For example, the user may trigger the download of the numbered notation picture of popular music A through the browser, thereby generating a download command carrying the numbered notation picture identifier.

Since the configuration parameters of different terminal devices are different, in order to make the downloaded picture adapt to the terminal device and achieve the best display effect. Therefore, after receiving the download instruction carrying the picture identifier, it is not directly downloaded from the server side, but before downloading the picture, the picture application parameters matching the terminal device are obtained. Among them, the specific information of the picture application parameters can be set according to the actual application needs, for example:

As an example, the image application parameters include screen resolution, and the screen resolution of the terminal device is obtained through a related driver.

Terminal devices with different screen resolutions have different requirements for picture pixels. for example:

A terminal device with a high screen resolution needs to obtain a relatively high-pixel picture, so that it can make full use of its own screen to provide users with a better picture display effect.

A terminal device with a low screen resolution cannot display pictures with high pixels, so it only needs to obtain pictures with relatively low pixels to avoid waste of pixels and traffic.

As an example, the picture application parameter may include the current memory capacity of the terminal device, and the current memory capacity is obtained by reading the RAM of the terminal device.

Specifically, current terminal devices with different memory capacities have different requirements for the size of pictures, for example:

For a terminal device with a large memory capacity, a relatively large picture can be obtained, thereby providing a user with a better picture display effect.

For a terminal device with a relatively small memory capacity, due to insufficient memory, it is only necessary to obtain a smaller picture to ensure that the picture can be displayed to the user.

For a terminal device that only supports the JPG format, it is necessary to obtain a picture in the JPG format, so as to ensure that the picture can be displayed to the user.

S120. Send a picture download request to the server, wherein the picture download request includes: picture identification and picture application parameters.

Specifically, a picture download request carrying a picture identifier and picture application parameters may be sent to the server, so that the server can acquire pictures matching the picture application parameters of the terminal device. For example, the server acquires a picture A in JPG format and a size smaller than 4M according to the received picture download request.
