It can be understood that: although the emphasis of each embodiment is different, the design concept is consistent. Moreover, for parts that are not described in detail in a certain embodiment, reference may be made to the detailed description throughout the specification, and further description is omitted.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for transmitting pictures by using a file server 20 as an execution subject according to an embodiment of the present invention, and the present specification provides the method operation steps as described in the embodiment or the flowchart, but may include more or less operation steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. When an actual image transmission device product is executed, the image transmission device product can be executed sequentially or in parallel according to the method shown in the embodiment or the figure (for example, a parallel processor or a multi-thread processing environment). Specifically, as shown in fig. 2, the method may include:
step S201: receiving an original picture sent by a first terminal and a unique identity of the original picture;
in the embodiment of the present invention, the original picture is a picture whose size and storage size are completely consistent with those of the original picture sent by the first terminal, the unique identity of the original picture is an identity for marking the uniqueness of the original picture, and the first terminal can identify whether the original pictures received for many times are the same original picture or not through the unique identity.
In some embodiments, the unique identifier of the original picture may be generated according to a third original picture directory address of the original picture locally and an identifier of a first terminal, and specifically, the first terminal packages and encrypts the third original picture directory address of the original picture and its own identifier to generate a string of codes, and uses the generated codes as the unique identifier of the original picture.
It can be understood that, if the first terminal sends the original picture at the third original picture directory address for multiple times, since the identity of the first terminal is fixed, the third original picture directory address is also the same, and the correspondingly generated multiple unique identities are also the same, that is, if the same original picture is sent for multiple times, the unique identity of the original picture sent for multiple times is also the same, and vice versa, that is, if different original pictures are sent for multiple times, the unique identities of the original pictures sent for multiple times are also different, so as to achieve the purpose of uniquely identifying the original picture by using the unique identities.
In some embodiments, two pictures which are stored in different positions of the first terminal and have completely consistent file names and storage sizes may be regarded as the same original picture, and correspondingly, the unique identifier of the original picture may be generated according to the file name and the storage size of the original picture, specifically, the first terminal packages and encrypts the file name and the storage size of the original picture to generate a string of codes, and the generated codes are used as the unique identifier of the original picture.
It can be understood that, by such an arrangement, the original pictures with the same file name and storage size stored at different locations of the first terminal can all be regarded as the same original picture, so that the file server can avoid repeatedly storing the same original picture from different storage locations of the first terminal.
In practical application, when the user a of the first terminal sends an original picture to the user B of the second terminal through the instant messaging application, the application program of the first terminal opens the album to allow the user a to select the original picture to be transmitted to the second terminal, or allow the user a to take a picture on site as the original picture to be transmitted to the second terminal. It should be noted that, no matter how the original picture to be transmitted is selected, the unique identifier of the original picture needs to be generated, so that when the original picture is sent to the file server, the unique identifier of the original picture is sent to the file server at the same time.
Step S203: determining a first original picture directory address and a first thumbnail directory address which correspond to the unique identity one by one;
in this embodiment of the present invention, the first original picture directory address is a storage address of the original picture in the file server, and the first thumbnail address is a storage address of the thumbnail of the original picture in the file server.
In some embodiments, in order to avoid the above situation, as shown in fig. 3, the determining the first original picture directory address and the first thumbnail directory address corresponding to the unique identifier may include:
step S301: inquiring whether the unique identity is recorded in a first preset database or not;
in an embodiment of the present invention, the first preset database is a database in the file server, and is configured to record the received unique identifiers of the various original pictures, the original picture directory addresses of the various original pictures in the file server, and the thumbnail directory addresses of the thumbnails of the various original pictures in the file server. And for any original picture stored by the file server, the unique identity, the original picture directory address at the file server and the thumbnail directory address at the file server are recorded in the first preset database in a one-to-one correspondence relationship.
Step S303: and when the unique identity is recorded in a first preset database, reading a first original picture directory address and a first thumbnail directory address which are recorded in the first preset database and correspond to the unique identity one by one.
It can be understood that, when the unique identifier is recorded in the first preset database, it indicates that the original picture with the unique identifier is already stored in the file server before, and at this time, the currently received original picture does not need to be stored, thereby avoiding waste of storage resources of the file server.
In other embodiments, in order to enable the file server to directly obtain the first original picture directory address and the first thumbnail directory address that are recorded in the first preset database and are in one-to-one correspondence with the unique identifier when receiving the original picture for the second time, so as to avoid that the file server repeatedly stores the original picture, and meanwhile, in order to avoid that the first original picture directory address and the first thumbnail directory address that are in one-to-one correspondence with the unique identifier cannot be successfully determined, as shown in fig. 4, the determining the first original picture directory address and the first thumbnail directory address that are in one-to-one correspondence with the unique identifier may further include:
step S305: when the unique identity is not recorded in a first preset database, generating a thumbnail of the original picture;
in the embodiment of the present invention, the thumbnail refers to a thumbnail obtained by compressing the size and storage size of the original picture in order to ensure the data loading speed.
Step S307: storing the original picture under a first original picture directory address, and storing the thumbnail under a first thumbnail directory address;
step S309: and writing the first original picture directory address, the first thumbnail directory address and the unique identity into the first preset database in a one-to-one corresponding relationship.
Step S205: and sending the first thumbnail directory address and the first original picture directory address to the first terminal, so that the first terminal sends the first thumbnail directory address and the first original picture directory address to the second terminal through a communication server, the second terminal downloads and displays the thumbnail under the first thumbnail directory address, and the second terminal downloads and displays the original picture under the first original picture directory address when receiving an instruction of a user to view the original picture of the thumbnail.
Referring to fig. 5, fig. 5 is a flowchart illustrating a method for transmitting pictures by using the second terminal 40 as an execution subject according to an embodiment of the present invention, and the present specification provides the method operation steps as described in the embodiment or the flowchart, but may include more or less operation steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. When an actual image transmission device product is executed, the image transmission device product can be executed sequentially or in parallel according to the method shown in the embodiment or the figure (for example, a parallel processor or a multi-thread processing environment). Specifically, as shown in fig. 5, the method may include:
step S501: receiving a first thumbnail directory address and a first original picture directory address sent by a first terminal through a communication server, wherein the first thumbnail directory address and the first original picture directory address are the first original picture directory address and the first thumbnail directory address which are determined to be in one-to-one correspondence with the unique identity after the file server receives the original picture and the unique identity of the original picture sent by the first terminal;
specifically, for the same original picture sent by the first terminal to different sessions of the second terminal, the second terminal may receive a first thumbnail directory address and a first original picture directory address sent by the first terminal through the communication server in the first session and the second session, respectively. The first session and the second session may be a single chat session between the user of the first terminal and the user of the second terminal, or may be a group chat session in which the user of the first terminal and the user of the second terminal participate.
Step S503: downloading and displaying the thumbnail under the first thumbnail directory address of the file server;
specifically, the user of the second terminal may download and display the thumbnail at the first thumbnail directory address of the file server in the first session or the second session.
Step S507: and when an instruction of a user for viewing the original picture of the thumbnail is received, downloading and displaying the original picture under the first original picture directory address of the file server.
Specifically, when receiving an instruction of a user to view the original picture of the thumbnail in a first session or a second session, the second terminal downloads and displays the original picture at the first original picture directory address of the file server.
In some embodiments, considering that if the second terminal receives the first thumbnail directory address non-first time (e.g., second time through the second session), that is, the second terminal has downloaded the thumbnail under the first thumbnail directory address from the file server for the first time in the first session, in order to avoid the user of the second terminal from repeatedly downloading the thumbnail, so as to reduce the waste of the traffic and the storage space of the second terminal, as shown in fig. 6, before performing step S503, the method may further include:
step S502: inquiring whether a second preset database records the first thumbnail directory address or not;
in an embodiment of the present invention, the second preset database is a first thumbnail directory address of the second terminal for recording various received original pictures in the file server and a second thumbnail directory address of the second terminal for recording various received original pictures in the second terminal, and for any original picture stored in the second terminal, the corresponding first thumbnail directory address and the corresponding second thumbnail directory address are recorded in the second preset database in a one-to-one correspondence relationship.
When the first thumbnail directory address is not recorded in the second preset database, downloading and displaying the thumbnail under the first thumbnail directory address of the file server;
accordingly, as mentioned above, in order to enable the second terminal to directly read the thumbnail stored for the first time locally when receiving the first thumbnail directory address for the second time, for example, in the second session, so as to avoid the user of the second terminal from repeatedly downloading the thumbnail, as shown in fig. 6, the method may further include:
step S504: and storing the downloaded thumbnail under a local second thumbnail directory address, and writing the second thumbnail directory address and the first thumbnail directory address into the second preset database in a one-to-one corresponding relationship.
In other embodiments, the method may further comprise:
and when the first thumbnail directory address is recorded in the second preset database, reading the thumbnail under the second thumbnail directory address corresponding to the first thumbnail directory address, and displaying the read thumbnail.
It is to be understood that, when the first thumbnail directory address is recorded in the second preset database, which indicates that the thumbnail at the first thumbnail directory address is downloaded from the file server and saved by the second terminal, the second terminal may directly read the thumbnail at the second thumbnail directory address and display the read thumbnail.
In some embodiments, considering that if the second terminal receives the first original picture directory address non-first time (for example, second time through the second session), that is, the second terminal has downloaded the original picture under the first original picture directory address from the file server for the first time in the first session, in order to avoid repeated downloading of the original picture by the user of the second terminal, so as to reduce the waste of the traffic and the storage space of the second terminal, as shown in fig. 6, before step S507, the method may further include:
step S506: inquiring whether the second preset database records the directory address of the first original picture;
when an instruction of a user for viewing the original picture of the thumbnail is received and the first original picture directory address is not recorded in the second preset database, executing a step of downloading and displaying the original picture under the first original picture directory address of the file server;
it can be understood that, when the first original picture directory address is not recorded in the second preset database, which indicates that the original picture at the first original picture directory address has not been downloaded from the file server by the second terminal, at this time, the original picture at the first original picture directory address of the file server is downloaded by the second terminal, and the downloaded original picture is displayed at the second terminal.
Correspondingly, as described above, in order to enable the second terminal to directly read the original picture stored locally for the first time when receiving the first original picture directory address for the second time, for example, in the second session, so as to avoid that the user of the second terminal repeatedly downloads the original picture, as shown in fig. 6, the method may further include:
step S508: and storing the downloaded original pictures in a local second original picture directory address, and writing the second original picture directory address and the first original picture directory address into the second preset database in a one-to-one corresponding relationship.
In other embodiments, the method may further comprise:
when an instruction of a user for viewing the original picture of the thumbnail is received and the first original picture directory address is recorded in the second preset database, reading the original picture at the second original picture directory address corresponding to the first original picture directory address, and displaying the read original picture.
