Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
An embodiment of the present disclosure provides an image transmission method, as shown in fig. 1, the image transmission method includes the following steps:
s110, the server side sends an application file uploading instruction to the client side.
The application file uploading instruction is used for indicating the client to send the application file to the server.
It should be noted that the instruction to upload the application file may instruct the client to send a plurality of application files to the server in a time-sharing manner, or may instruct the client to send a plurality of application files to the server at the same time.
If the application file contains a plurality of application types, the server side can only instruct the client side to send the application file uploading instruction to the client side in a time-sharing mode or simultaneously send a plurality of application files belonging to one application type.
And S120, after receiving the application file uploading instruction sent by the server, the client sends the application file to the server and deletes the local application file.
The client can obtain or generate the application file, and after receiving the application file uploading instruction sent by the server, the client can send the application file to the server.
The local application file refers to the application file stored in the client, and the application file can be automatically deleted after being sent to the server, so that the application file is prevented from being leaked, and the safety is improved.
The client sends the application File to the server, and the application File can be uploaded by a File Transfer Protocol (File Transfer Protocol).
For example, in a video surveillance system, a client may include a camera that sends a captured video file to a server and deletes an application file stored locally on the camera.
S130, the server receives the application file sent by the client.
It should be noted that the server may be set in a machine room with a very high security level, and may be set to only upload and not output, so that the security of storing the application file uploaded to the server by the client in the server is very high.
S140, the client sends a push instruction to the server.
The pushing instruction is used for indicating the server side to push the image corresponding to the application file to be pushed to the client side.
It can be understood that the application file is only stored by the server side, and therefore, when the user needs to view the application file, the user can only view the application file in the form of image transmission.
S150, after receiving the push instruction sent by the client, the server acquires the image corresponding to the application file to be pushed.
It should be noted that the image corresponding to the application file to be pushed is collected, and may include an independent image, or may include an image belonging to a certain frame in a moving picture or a video.
Illustratively, if the application file to be pushed is 1.doc, the file of the word application type is operated, and if the interface presented after operation is an article with white background and black characters, the interface image is collected as an image corresponding to the application file to be pushed and sent to the client.
And S160, the server collects the image corresponding to the application file to be pushed and sends the image to the client.
When the collection is completed, the server side can send the image corresponding to the application file to be pushed to the client side.
And S170, the client receives the image sent by the server.
It can be understood that the server can collect an image of an application file running, encode the collected image, generate encoded data, send the encoded data to the client, and then the client decodes the encoded data to obtain an image corresponding to the application file to be pushed.
If a plurality of clients send push instructions to the server at the same time, the server acquires images corresponding to application files to be pushed after receiving the push instructions sent by the plurality of clients, and then the images can be sent to the plurality of clients.
Here, if the client includes a display, the received image transmitted by the server may be displayed by the display. If the client includes multiple displays and receives multiple images, each display may be used to display one image. That is to say, the image transmission method provided by the embodiment of the application can be applied to scenes such as training, teleconferencing and the like which need to push application files to a plurality of clients.
The embodiment of the disclosure provides an image transmission method, wherein after receiving an application file uploading instruction sent by a server, a client sends an application file to the server, deletes a local application file, and prevents the application file from being leaked from the client, and then, when the client needs to check an image corresponding to the application file to be pushed, the client sends a pushing instruction to the server to receive the image corresponding to the application file to be pushed sent by the server. Therefore, the application file can be checked at any time through the client under the condition of ensuring the absolute safety of the application file, and the safety is improved.
Optionally, after S130 above, before S140, as shown in fig. 2, the method further includes:
s131, the client sends an acquisition request to the server.
The obtaining request is used for obtaining an application file list; the application file list comprises a plurality of application files and file identifications which are respectively in one-to-one correspondence with the application files; the file identifier includes a number and a file name corresponding to the plurality of application files one to one.
It should be noted that the form of the file identifier may be one or a combination of several of chinese characters, english characters, numbers, or symbols, and the like, and the present application is not particularly limited to this, and may be set as needed.
Based on this, if the application file includes a plurality of application types, the obtaining request may be used to obtain an application file list corresponding to one or several application types. It is understood that the application file list includes application files of one or several application types and file identifications corresponding to the application files of the one or several application types one by one, and the file identifications include numbers and file names corresponding to the application files of the one or several application types one by one.
And S132, after receiving the acquisition request, the server sends an application file list to the client.
If the obtaining request is used for obtaining the application file lists corresponding to all the application files, the server side sends the application file lists corresponding to all the application files to the client side after receiving the obtaining request.
If the obtaining request is only used for obtaining the application files of one or a few application types, the server may only send the application file list corresponding to the application files of one or a few application types to the client after receiving the obtaining request. At this time, the data sent by the server to the client is less, so that the bandwidth is saved, and the efficiency is higher when the subsequent client determines the file identifier of the file to be pushed.
Illustratively, as shown in fig. 3, the application files stored by the server include 4 types, which are Word application, Excel application, PPT application, PDT application or PDF application respectively. Wherein, the Word application category comprises three files with numbers of 11, 12 and 13 respectively and file names of 1.doc, 2.doc and 3. doc; the Excel application type comprises three files with codes of 21, 22 and 23 respectively and file names of 1.xlsx, 2.xlsx and 3. xlsx; the PPT application category comprises three files with the numbers of 31, 32 and 33 respectively and the file names of 1.PPT, 2.PPT and 3. PPT; the PDT or PDF application type comprises three files numbered 41, 42, 43, respectively, with file names 1.PDF, 2.PDF, 3. PDF.
The server stores the 12 application files, and generates a corresponding application file list after receiving the acquisition request, as shown in fig. 4, in which the application files, file identifiers, serial numbers, and file names are in one-to-one correspondence.
It can be understood that the server may further include application types such as a browser application, a Video application, an app application, and an Image application, which are not particularly limited in this application and may be specifically classified according to needs.
The Image application type refers to pictures and comprises picture files of all formats such as jpg, png, gif and the like; the Video application type refers to a Video, and includes files of all formats of mp4, mkv, rmkb, avi, and the like.
S133, the client determines the file identification of the application file to be pushed according to the application file list.
The client can find out the file identifier of one of the application files in a traversal mode according to the application file list, and the file identifier is used as the file identifier of the application file to be pushed.
In addition, if the application file list contains a plurality of application types, one application type may be determined first, and the file identifier of the application file to be pushed is searched for in the application type, so that the search efficiency can be improved. Of course, the file identifier of the application file to be pushed may also be determined in other manners, which is not particularly limited in this application and may be set as needed.
Optionally, on this basis, the S140 includes:
and the client sends a push instruction carrying the file identifier to the server.
The push instruction carrying the file identifier is used for instructing the server to push the image corresponding to the application file to be pushed carrying the file identifier.
The S150 includes:
and after receiving a push instruction carrying a file identifier sent by the client, the server acquires an image corresponding to the application file to be pushed, carrying the file identifier.
For example, referring to fig. 3, if the client determines that the file identifier of the application file to be pushed is 11/1.doc according to the application file list, that is, the number of the application file to be pushed, which needs to be pushed by the server, is 11 and the file name is 1.doc, therefore, the application file to be pushed determined by the client refers to the 1 st application file in the word application type, and after receiving a push instruction carrying the file identifier of 11/1.doc and sent by the client, the server acquires an image corresponding to the application file to be pushed, which is numbered 11 and has the file name of 1. doc.
S134, the client determines the first address identification.
The first address identifier is used for indicating an address for receiving an image corresponding to the application file to be pushed, and the first address identifier may be a Rid address and a sip address.
It should be noted that the first address identifier may be set in the client in advance. The first address identifier may be one or multiple, and the application is not particularly limited in this respect and may be set as needed.
Here, the address indicated by the first address identifier may be an address space of internal hardware of the client, may also be an address space of external hardware of the client, may be address spaces on different clients, and may also be different address spaces on the same client.
Optionally, on this basis, the S140 includes:
the client sends a push instruction carrying the file identifier and the first address identifier to the server.
It can be understood that, here, the push instruction is used to instruct the server to push the image corresponding to the application file to be pushed carrying the file identifier, and is used to instruct to receive the image corresponding to the application file to be pushed by using the address at the first address identifier.
The S150 includes:
and the server receives a push instruction which is sent by the client and carries the file identifier and the first address identifier.
Based on this, as shown in fig. 5, the method further includes:
and S151, the server sends the second address identifier to the client.
And the second address mark is used for indicating the address of acquiring the image corresponding to the application file to be pushed.
And after the server runs the application file to be pushed, acquiring an image corresponding to the application file to be pushed by using the address identified by the second address.
S152, after the client receives the second address identifier sent by the server, the corresponding relation between the first address identifier and the second address identifier is established.
The first address identifier and the second address identifier may be in a one-to-one relationship, or may be in a many-to-one relationship.
On this basis, after the above S170, the method further includes:
the client finds the first address identifier corresponding to the image by utilizing the corresponding relation of the first address identifier and the second address identifier according to the second address identifier corresponding to the image, and then stores the received image at the address of the first address identifier corresponding to the second address identifier.
Illustratively, the client sends an acquisition request to the server, and starts to select an application file to be pushed after receiving an application file list sent by the server. If the client determines that the number of the application file to be pushed is 11, the file name is 1.doc, and the three first address identifiers are 00 and 0.0.0.1 respectively; 01, 0.0.0.2; 02, 0.0.0.3; when the client sends a push instruction to the server, the push instruction is used for indicating the server to push the application file with the serial number of 11 and the file name of 1.doc to the client, and the application file is pushed to the addresses of the three first address identifiers, after receiving the push instruction, the server determines a second address identifier and sends the second address identifier to the client, and the client establishes the corresponding relationship between the second address identifier and the three first address identifiers; the server side acquires an image of the application file to be pushed, which carries the file identifier, by using the address at the second address identifier, and then sends the image to the client side, and the client side stores the received image at the addresses of the three first address identifiers by using the three first address identifiers corresponding to the second address identifier to which the image belongs.
