The large-screen projection application is an application which is arranged at a screen projection end and is used for realizing the screen projection sharing operation of the file. As an example, the large screen projection application comprises a file playing module and a screen projection connection module. The file playing module is a module for realizing file playing, and can support playing multimedia files (such as audio, video, pictures and other files) and also can support playing common office files (such as WORD, EXCEL, PPT and other files). The screen projection connecting module is a module which is arranged at a screen projection end and used for realizing communication with other equipment, can adopt a point-to-point connecting mode to carry out screen projection application communication with a mobile phone, and can adopt a long connecting mode to carry out communication with a cloud system.

The cloud system is a system which is arranged at the cloud and used for achieving screen projection and sharing operation of files. As an example, the cloud system includes a cloud file management module, a data management module, and a cloud pushing module. The cloud file management module is used for receiving files uploaded by the mobile phone screen-casting application, storing the received files in the cloud database, and sending the files to the mobile phone screen-casting application and the large-screen-casting application.

In an embodiment, as shown in fig. 2, a file screen-casting sharing method is provided, which is described by taking the file screen-casting sharing system in fig. 1 as an example, and includes the following steps:

s201: the sharing mobile phone terminal generates a file sharing instruction corresponding to the target file ID and sends the file sharing instruction to the cloud terminal system;

s202: the cloud system responds to the file sharing instruction, generates a file sharing URL corresponding to the target file ID, and sends the file sharing URL to the sharing mobile phone terminal;

s203: the sharing mobile phone end sends the file sharing URL to the screen casting end;

s204: the screen projection terminal generates a file sharing two-dimensional code corresponding to the file sharing URL according to the file sharing URL and displays the file sharing two-dimensional code;

s205: the participating mobile phone terminal scans the file sharing two-dimensional code, generates a file downloading instruction corresponding to the file sharing URL, and sends the file downloading instruction to the cloud end system;

s206: and the cloud system receives the file downloading instruction, analyzes the file downloading instruction, acquires a target file and sends the target file to the participating mobile phone terminal.

The object file ID is an identifier for uniquely identifying a certain object file. The target file refers to a file which needs to be subjected to screen projection sharing at this time. The file sharing instruction is an instruction triggered by the sharing mobile phone end and used for realizing file sharing.

As an example, in step S201, the sharing mobile phone may select a specific meeting file or teaching file in the mobile phone screen-casting application, and determine the meeting file or teaching file as a target file; the file sharing method includes the steps that a file sharing button of the screen-casting application of the mobile phone is clicked by a user, a file sharing instruction corresponding to a target file ID can be generated, the file sharing instruction is sent to a cloud end system, namely the file sharing instruction is sent to the cloud end system through a mobile phone connecting module of the sharing mobile phone end and a cloud end pushing module of the cloud end system, and therefore the cloud end system can execute subsequent file screen-casting sharing operation.

The file sharing URL is used for determining a path or other associated information of the target file in the cloud system.

As an example, in step S202, after receiving a file sharing instruction sent by a sharing mobile phone, the cloud system analyzes the file sharing instruction, and determines a target file ID corresponding to the file sharing instruction; and then, generating a file sharing URL corresponding to the target file ID so as to search the target file by utilizing the file sharing URL.

In this example, after parsing the file sharing instruction and determining the target file ID corresponding to the file sharing instruction, the cloud system may query the cloud database based on the target file ID to determine whether the cloud database stores the target file; if the cloud database stores the target file, generating a file sharing URL corresponding to the ID of the target file; and if the target file is not stored in the cloud database, generating file non-uploading information, and sending the file non-uploading information to the sharing mobile phone terminal. When receiving information that the file is not uploaded, the sharing mobile phone end needs to upload the target file to the cloud end system. The cloud system receives the target file, generates file recording information corresponding to the target file, and sends the file recording information to the sharing mobile phone terminal.

The file recording information is used for recording information of a target file stored in a cloud database. As an example, the file record information includes, but is not limited to, a target file name, a target file size, a target file ID, a target file path, a target file owner, and the like corresponding to the target file. The target file name refers to the name of the target file. The target file ID is an ID for uniquely identifying a certain target file. The target file path refers to a path of the target file stored in the cloud database. The target file owner refers to an owner of the target file, namely, a sharing user who operates the sharing mobile phone to upload the target file.

As an example, in step S203, after receiving the file sharing URL sent by the cloud system, the sharing mobile phone may determine the device ID and the device MAC corresponding to the screen casting end, and send the file sharing URL to the corresponding screen casting end through the peer-to-peer connection established between the sharing mobile phone and the screen casting end, so that the screen casting end may share the file sharing URL.

As an example, in step S204, the screen projection end may receive a file sharing URL transmitted by the sharing mobile phone end in a point-to-point connection manner, and may use a two-dimensional code generation tool to encode the file sharing URL to generate a file sharing two-dimensional code corresponding to the file sharing URL. The screen projection end displays the file sharing two-dimensional code, so that the participating users can utilize the code scanning application in the participating mobile phone end to scan the file sharing two-dimensional code displayed by the screen projection end, and the follow-up file sharing operation is completed.

The file downloading instruction is an instruction which participates in mobile phone end triggering and is used for achieving the purpose of file downloading.

As an example, in step S205, a code scanning application in the participating mobile phone scans the file sharing two-dimensional code displayed by the screen projection end to obtain a file sharing URL corresponding to the file sharing two-dimensional code; analyzing the file sharing URL, and acquiring information such as a download website and a target random number corresponding to the screen-casting application of the mobile phone; then, generating a file downloading instruction corresponding to the file sharing URL according to a downloading website and a target random number corresponding to the mobile phone screen-casting application; and then, the participating mobile phone end can send the file downloading instruction to the cloud end system.

As an example, in step S206, the cloud system receives a file downloading instruction sent by the mobile phone, analyzes the file downloading instruction, and determines a target random number in the file downloading instruction; then, inquiring a cloud database according to the target random number, and acquiring a target file ID corresponding to the target random number; and then, inquiring a cloud database according to the ID of the target file to obtain the target file, and then sending the target file to the participating mobile phone end, so that the participating mobile phone end can receive the target file to fulfill the aim of screen-casting and sharing of the file.

In the file screen-casting sharing method provided by this embodiment, the sharing mobile phone end sends the generated file sharing instruction to the cloud end system, and sends the file sharing URL returned by the cloud end system to the screen casting end, so that the screen casting end displays the file sharing two-dimensional code corresponding to the file sharing URL; the participating mobile phone end scans the file sharing two-dimensional code and sends a file downloading instruction to the cloud system to receive the target file sent by the cloud system, so that the file screen-casting sharing operation process is simple, and the operation convenience is guaranteed.

In an embodiment, as shown in fig. 3, in step S202, that is, the cloud system responds to the file sharing instruction, generates a file sharing URL corresponding to the target file ID, and sends the file sharing URL to the sharing mobile phone terminal, where the steps include:

s301: the cloud system analyzes the file sharing instruction and generates a target random number corresponding to the target file ID;

s302: the cloud system determines the target file ID and the target random number as target sharing information, and stores the target sharing information in a cloud database in a correlation manner;

s303: the cloud system generates a file sharing URL corresponding to the target file ID based on the download website and the target random number corresponding to the mobile phone screen-casting application, and sends the file sharing URL to the sharing mobile phone terminal.

The target random number is a random number which is generated by the system at the current moment and is associated with the target file ID.

As an example, in step S301, the cloud system parses the file sharing instruction to obtain a target file ID in the file sharing instruction; when the cloud database is stored in the target file, a random number generation script can be adopted to generate a target random number corresponding to the target file. For example, the cloud system may generate a random number of 16 bytes in length as the target random number according to the received target file ID. The target random number has randomness, so that the target random number is used for carrying out security verification subsequently, and the screen-casting sharing security of the target file is guaranteed.

The target sharing information is used for recording information related to file screen projection sharing.

As an example, in step S302, after generating the target random number corresponding to the target file ID, the cloud system may determine the target file ID and the target random number as target sharing information in a Key-Value form, and store the target sharing information in the cloud database for subsequent query operation.

The downloading website corresponding to the screen-casting application of the mobile phone refers to an official website address link of the screen-casting application of the mobile phone.

As an example, in step S303, the cloud system may encapsulate, by using a URL format, a download website corresponding to a mobile phone screen-casting application and a target random number generated at the current time of the system, which are stored in advance by the system, to form a file sharing URL, so that the file sharing URL includes information such as the download website and the target random number corresponding to the mobile phone screen-casting application, and the participating mobile phone terminal may obtain a target file according to the file sharing URL, thereby completing the file screen-casting sharing operation.

Understandably, the file sharing URL includes a download website and a target random number corresponding to the mobile phone screen-casting application, and the target random number and the target file ID are stored in association, so that the participating mobile phone can directly obtain the target file according to the target file ID corresponding to the target random number according to the file sharing URL, and also can obtain the target file according to the target file ID corresponding to the target random number by the mobile phone screen-casting application first according to the download website corresponding to the mobile phone screen-casting application and then by the mobile phone screen-casting application, so as to ensure feasibility and safety of the file screen-casting sharing operation.

In an embodiment, after step S301, that is, after the cloud system determines the target file ID and the target random number as the target sharing information and stores the target sharing information in the cloud database in an associated manner, the file screen-casting sharing method further includes: and the cloud system determines the validity period of the random number corresponding to the target random number.

As an example, after generating the target random number corresponding to the target file ID, the cloud system may determine a random number validity period corresponding to the target random number according to the current time of the system and a preset validity duration. For example, when the current time of the system is T1 and the validity period is T, the validity period of the random number corresponding to the target random number is the period from T1 to T1+ T. Understandably, after the cloud system generates the target random number, the validity period of the random number corresponding to the target random number needs to be recorded, so that the security verification is performed based on the validity period of the random number, the timeliness of the target random number is guaranteed, and the security of file screen-casting sharing operation is further guaranteed.

In an embodiment, as shown in fig. 4, in step S205, that is, participating in the mobile phone scanning the file sharing two-dimensional code, generating a file downloading instruction corresponding to the file sharing URL, and sending the file downloading instruction to the cloud end system, the method includes:

s401: the participating mobile phone terminal scans the file sharing two-dimensional code by adopting code scanning application to obtain a file sharing URL;

s402: the participating mobile phone side analyzes the file sharing URL to obtain target sharing information, wherein the target sharing information comprises a target random number;

s403: and the participating mobile phone terminal generates a file downloading instruction based on the target random number and sends the file downloading instruction to the cloud terminal system.

As an example, in step S401, the participating mobile phone may employ a code scanning application, including but not limited to a mobile phone screen-casting application, a system camera, a WeChat, or other applications with a code scanning function, to scan the file sharing two-dimensional code displayed on the screen-casting terminal, so as to identify a file sharing URL in the file sharing two-dimensional code.

As an example, in step S402, the participating mobile phone terminal parses the file sharing URL by using a parsing tool corresponding to the URL format to obtain target sharing information corresponding to the file sharing URL, where the target sharing information includes a target random number, and the target random number is a random number formed by the cloud system based on a file sharing instruction sent by the sharing mobile phone terminal.

As an example, in step S403, the participating mobile phone end may generate a file downloading instruction related to the target random number based on the parsed target random number, and send the file downloading instruction to the cloud system, so that the cloud system may obtain a target file related to the target random number according to the file downloading instruction, and send the target file to the participating mobile phone end, so that the participating mobile phone end may obtain a target file shared by the sharing mobile phone end, and complete the file screen-casting and sharing operation.

In one embodiment, the target sharing information further includes a download website corresponding to the mobile phone screen-casting application;

step S403, namely, the participating mobile phone generates a file downloading instruction based on the target random number, and sends the file downloading instruction to the cloud end system, including:

s4031: when the code scanning application is a mobile phone screen projection application, the participating mobile phone end generates a file downloading instruction based on the target random number and sends the file downloading instruction to the cloud end system;

s4032: when the code scanning application is not the mobile phone screen projection application, the participating mobile phone side downloads and installs the mobile phone screen projection application based on the downloading website, jumps to the mobile phone screen projection application, generates a file downloading instruction based on the target random number, and sends the file downloading instruction to the cloud end system.

As an example, in step S402, the mobile phone terminal is involved in parsing the file sharing URL, and the obtained target sharing information includes not only the target random number but also a download website corresponding to the mobile phone screen-casting application. Correspondingly, in step S403, the participating end participates in the mobile phone end, generates a file download instruction based on the target random number, and sends the file download instruction to the cloud end system, which specifically includes the following two cases:

in the first case, when the code scanning application participating in the file sharing two-dimensional code scanning at the mobile phone end is the mobile phone screen casting application, a corresponding file downloading instruction can be generated directly based on the target random number and sent to the cloud system, so that the cloud system sends the target file to the mobile phone screen casting application participating at the mobile phone end, and the file screen casting sharing function is completed through the mobile phone screen casting application.

In the second case, when the code scanning application participating in the file sharing two-dimensional code scanning at the mobile phone end is not the mobile phone screen projection application, the mobile phone screen projection application capable of realizing the file screen projection sharing function is not installed at the participating mobile phone end, and at the moment, the mobile phone screen projection application can be downloaded and installed based on the download website corresponding to the analyzed mobile phone screen projection application; and then skipping to the installed mobile phone screen-casting application, generating a corresponding file downloading instruction directly based on the target random number, and sending the file downloading instruction to the cloud system, so that the cloud system sends the file downloading instruction to the mobile phone screen-casting application participating in the mobile phone terminal to the target file, and the file screen-casting sharing function is completed through the mobile phone screen-casting application.

In an embodiment, as shown in fig. 5, in step S403, that is, the participating mobile phone generates a file download instruction based on the target random number, and sends the file download instruction to the cloud end system, where the step includes:

s501: the participating mobile phone end generates an information acquisition instruction corresponding to the target random number, and sends the information acquisition instruction to the cloud end system;

s502: the cloud system receives the information acquisition instruction, analyzes the information acquisition instruction, acquires a target random number, queries a cloud database based on the target random number, determines a target file ID corresponding to the target random number, acquires file recording information corresponding to the target file ID, and sends the file recording information to the participating mobile phone end;

s503: and the participating mobile phone end displays the file recording information, generates a file downloading instruction carrying the target random number, and sends the file downloading instruction to the cloud end system.

The information acquisition instruction is used for acquiring file record information corresponding to the target file.

As an example, in step S501, after the participating mobile phone scans a code and analyzes a target random number, the participating mobile phone may receive an information sharing button clicked by a participating user in a mobile phone screen application, generate an information obtaining instruction corresponding to the target random number, and send the information obtaining instruction to the cloud end system.

As an example, in step S502, after receiving an information acquisition instruction sent by a participating mobile phone, the cloud system may analyze the information acquisition instruction to acquire a target random number; then, inquiring a cloud database based on the target random number, determining target sharing information corresponding to the target random number, and determining a target file ID in the target sharing information as a target file ID corresponding to the target random number; and then, inquiring a cloud database based on the target file ID, determining file record information corresponding to the target file ID, and sending the file record information to the participating mobile phone terminal.

In this example, in step S502, the cloud system receives the information obtaining instruction, parses the information obtaining instruction, and after obtaining the target random number, needs to query the cloud database according to the target random number to determine a random number validity period corresponding to the target random number; when the current time of the system is within the validity period of the random number, inquiring a cloud database based on the target random number, determining a target file ID corresponding to the target random number, acquiring file record information corresponding to the target file ID, and sending the file record information to a participating mobile phone terminal; and when the current time of the system is not within the validity period of the random number, generating sharing failure information, and sending the sharing failure information to the participating mobile phone terminal.

As an example, in step S503, the participating mobile phone may receive and display the file record information, and learn information such as a target file name, a target file size, a target file ID, a target file path, and a target file owner corresponding to the target file, so that the participating user may determine whether to download the target file. In this example, when the participating user determines that the target file needs to be downloaded, a file downloading instruction carrying the target random number may be generated, and the file downloading instruction is sent to the cloud end system. The cloud system can determine a target file according to a file downloading instruction carrying a target file ID or a target random number, and then sends the target file to the participating mobile phone end to complete file screen-casting sharing operation.

Understandably, after the participating mobile phone end displays the file recording information, the file downloading instruction can be determined and generated according to the user requirement, so that the participating user can determine whether to download the target file after preliminarily knowing the related information of the target file, and the experience of the participating user is improved. The participating mobile phone end generates a file downloading instruction carrying the target random number, so that the cloud system can perform time efficiency verification according to the target random number, and then determines the ID of the target file according to the target random number, so as to obtain the target file, and the time efficiency and the safety of the target file determination are guaranteed.

In another embodiment, in step S403, that is, the participating mobile phone generates a file downloading instruction based on the target random number, and sends the file downloading instruction to the cloud end system, the method includes:

and the participating mobile phone terminal generates a file downloading instruction carrying the target random number based on the target random number, and sends the file downloading instruction to the cloud terminal system.

As an example, in step S403, after the participating mobile phone scans the code and analyzes the target random number, the participating mobile phone may receive a file download button in the screen-casting application of the participating user clicked the mobile phone, and may directly generate a file download instruction carrying the target random number, and send the file download instruction to the cloud end system, so that the cloud end system sends the target file to the participating mobile phone according to the file download instruction.

In an embodiment, as shown in fig. 6, in step S206, that is, the cloud system receives the file downloading instruction, analyzes the file downloading instruction, obtains the target file, and sends the target file to the participating mobile phone end, where the steps include:

s601: the cloud system receives the file downloading instruction, analyzes the file downloading instruction and obtains a target random number;

s602: the cloud system queries a cloud database based on the target random number, determines a target file ID corresponding to the target random number, acquires a target file corresponding to the target file ID, and sends the target file to the participating mobile phone terminals.

As an example, in step S601, the cloud system receives a file downloading instruction sent by the participating mobile phone, and parses the file downloading instruction to obtain the target random number, so as to query and determine the target file by using the target random number.

As an example, in step S602, after the target random number is parsed, the cloud system queries the cloud database based on the target random number, determines target sharing information corresponding to the target random number, and determines a target file ID in the target sharing information as the target file ID corresponding to the target random number; then, inquiring a cloud database based on the ID of the target file, determining file record information corresponding to the ID of the target file, determining a path of the target file from the file record information, and further acquiring the target file; and then, sending the target file to a participating mobile phone end so as to achieve the purpose of screen casting and sharing of the file.

In this example, in step S602, after the cloud system analyzes the file downloading instruction and obtains the target random number, the cloud database needs to be queried according to the target random number, and the random number validity period corresponding to the target random number is determined; when the current time of the system is within the validity period of the random number, inquiring a cloud database based on the target random number, determining a target file ID corresponding to the target random number, acquiring a target file corresponding to the target file ID, and sending the target file to a participating mobile phone end; and when the current time of the system is not within the validity period of the random number, generating sharing failure information, and sending the sharing failure information to the participating mobile phone terminal.

In an embodiment, as shown in fig. 7, after step S203, that is, after the sharing mobile phone sends the file sharing URL to the screen casting end, the file screen casting and sharing method further includes:

s701: the sharing mobile phone end generates a sharing suspension instruction corresponding to the ID carrying the target file, and sends the sharing suspension instruction to the cloud end system;

s702: the cloud system receives the sharing suspension instruction, analyzes the sharing suspension instruction, determines the ID of the target file, and deletes the target sharing information corresponding to the ID of the target file stored in the cloud database.

The sharing suspension instruction is an instruction for the sharing user to actively trigger the sharing operation to stop.

As an example, in step S701, the sharing mobile phone sends a file sharing instruction to the cloud system, and sends a file sharing URL returned by the cloud system to the screen projection end, so that after the screen projection end displays the file sharing two-dimensional code, the screen projection end can receive a sharing stop button that the sharing user clicks the mobile phone screen projection application, generate a sharing stop instruction corresponding to the target file ID, and send the sharing stop instruction to the cloud system.

As an example, in step S702, after receiving the sharing suspension instruction sent by the sharing mobile phone, the cloud system may parse the sharing suspension instruction, determine a target file ID corresponding to a target file that needs to be stopped from sharing, and then delete target sharing information corresponding to the target file ID stored in the cloud database, that is, delete a target random number corresponding to the target file ID, so that when subsequently receiving a file download instruction carrying the target random number, the cloud system cannot find the corresponding target file, thereby achieving the purpose of stopping sharing, so that the sharing user can operate a mobile phone screen-casting application of the sharing mobile phone, thereby implementing the function of stopping sharing, so as to meet the user demand and improve the user experience.

In an embodiment, before step S201, that is, before the sharing mobile phone generates a file sharing instruction corresponding to the target file ID and sends the file sharing instruction to the cloud end system, the file screen-casting sharing method further includes:

s801: the sharing mobile phone end generates a screen throwing control instruction carrying the ID of the target file, and sends the screen throwing control instruction to the screen throwing end;

s802: the screen projection end analyzes the screen projection control instruction, generates a file screen projection instruction corresponding to the target file ID, and sends the file screen projection instruction to the cloud end system;

s803: the cloud system analyzes the file screen-casting instruction, acquires a target file corresponding to the ID of the target file, and sends the target file to a screen casting end;

s804: and the screen projection end receives the target file and demonstrates the target file.

The screen projection control instruction is an instruction which is triggered by the sharing mobile phone end and is used for realizing file screen projection control.

As an example, in step S801, the sharing mobile phone may select a specific meeting file or teaching file in the mobile phone screen-casting application, and determine the meeting file or teaching file as a target file; and when the user clicks a file screen-casting button of the mobile phone screen-casting application, a screen-casting control instruction corresponding to the target file ID can be generated, and the screen-casting control instruction is sent to the cloud end system.

The file screen-casting instruction is an instruction which is triggered by a screen-casting end and is used for acquiring files needing screen casting from a cloud system.

As an example, in step S802, a large-screen-projection application at a screen projection end receives a screen projection control instruction sent by a sharing mobile phone end, analyzes the screen projection control instruction, and obtains a target file ID in the screen projection control instruction; then, a file screen-casting instruction carrying the target file ID can be formed based on the target file ID, and the file screen-casting instruction is sent to the cloud end system.

As an example, in step S803, the cloud system receives a file screen-casting instruction sent by a screen-casting end, analyzes the file screen-casting instruction, and obtains a target file ID in the file screen-casting instruction; and then inquiring a cloud database based on the ID of the target file to obtain the target file, and then sending the target file to a screen projection end.

As an example, in step S894, the large-screen-projection application at the screen projection end may receive the target file sent by the cloud system, and then display the target file, so that the participating user can know the detailed information of the target file through the screen projection end, thereby achieving the purpose of sharing the file screen projection.

In an embodiment, as shown in fig. 9, in step S801, that is, the sharing mobile phone generates a screen projection control instruction carrying the target file ID, and sends the screen projection control instruction to the screen projection end, the method includes:

s901: the sharing mobile phone end generates a screen projection control instruction corresponding to the ID carrying the target file, and judges whether the sharing mobile phone end stores file record information corresponding to the ID of the target file or not;

s902: when the sharing mobile phone end stores the file record information corresponding to the target file ID, sending a screen casting control instruction to the screen casting end;

s903: and when the sharing mobile phone end does not store the file record information corresponding to the ID of the target file, the sharing mobile phone end sends the target file to the cloud end system, and after the file record information returned by the cloud end system is received, the sharing mobile phone end sends a screen projection control instruction to the screen projection end.

As an example, in step S901, after the sharing mobile phone generates a screen-casting control instruction corresponding to the target file ID, it needs to determine whether the sharing mobile phone stores file record information corresponding to the target file ID, so as to determine whether the target file is uploaded to the cloud system.

As an example, in step S902, when the sharing mobile phone end stores the file record information corresponding to the target file ID, it indicates that the sharing mobile phone end has sent the target file to the cloud system before the current time of the system, and at this time, the screen-casting control instruction may be directly sent to the screen-casting end, so that the screen-casting end queries the target file to be screen-cast and displayed from the cloud system according to the target file ID.

As an example, in step S903, when the sharing mobile phone end does not store file record information corresponding to the target file ID, it is stated that the sharing mobile phone end does not send the target file to the cloud system before the current time of the system, at this time, the target file needs to be sent to the cloud system first, and after receiving file record information returned by the cloud system, a screen-casting control instruction is sent to the screen-casting end, so that the screen-casting end queries the target file to be screen-cast and displayed from the cloud system according to the target file ID, so as to ensure reliability of the screen-casting end in screen-casting and displaying the target file.

In one embodiment, as shown in fig. 10, the screen-projection end receives a target file, and the target file is presented, including:

s1001: the screen projection end receives the target file, obtains a file type corresponding to the target file, and judges whether a target demonstration application corresponding to the file type exists or not;

s1002: when a target demonstration application exists at the screen projection end, displaying a target file through the target demonstration application;

s1003: and when the target demonstration application does not exist, the screen projection end downloads and installs the application installation package corresponding to the target demonstration application, and the target file is displayed through the target demonstration application.

Wherein the target presentation application is an application for presenting a target file.

As an example, in step S1001, after receiving a target file sent by the cloud system, the screen projection end may determine a file type corresponding to the target file. In this example, the screen projection end can identify a file suffix of the target file, and determine the file type corresponding to the target file according to the file suffix, for example, when the file suffix of the target file is doc, the file type can be determined to be a text type; when the file suffix of the target file is.wav, it can be determined that the file type thereof is the audio type. Then, the screen projection end needs to judge whether a target demonstration application corresponding to the file type exists or not so as to determine whether the target file can be displayed or not.

As an example, in step S1002, when the target presentation application exists, the screen-projecting end may jump to open the target presentation application, and the target file is presented through the target presentation application, so as to ensure the reliability of the target file presentation.

As an example, in step S1003, when the target presentation application does not exist, the screen-casting terminal may jump to the application download interface, download the target presentation application corresponding to the file type, open the target presentation application, and demonstrate the target file through the target presentation application, thereby ensuring the reliability of the target file demonstration.
