Step S101: The client sends the mail operation request and related device information of the embedded device to the first server. Before sending the mail operation request and device information, the client can also perform compression and encryption operations on it, so that the transmitted The amount of data is reduced and the security of information transmission can be increased;

Step S102: The first server receives and parses the above-mentioned compressed and encrypted information, and uses the same compression method and decryption algorithm to perform decompression and decryption operations, obtains the above-mentioned mail operation request and related device information, and sends the mail operation request forward to the second server;

Step S103: the second server executes the corresponding mail operation according to the above mail operation request, obtains the corresponding mail operation result, and sends the mail operation result to the first server;

Step S104: The first server performs relevant adaptation processing on the operation result adapted to the embedded device according to the above-mentioned device information, obtains the processing result after the adaptation processing, and sends the processing result to the client, and then sends the Before sending the processing result, the first server may also perform compression and encryption operations on the processing result, and send the compressed and encrypted results to the client;

Step S105: The client receives and parses the information sent by the first server, performs decryption and decompression operations according to the same encryption and decryption algorithm and decompression algorithm, and displays the decrypted and decompressed processing results on the embedded device show.

in:

In the step S101, the device information may include the identification information of the embedded device, screen size information, screen resolution information, and file format information supported by the embedded device, etc., and the mail operation request may include Contains the user name information and request content information requesting the mail operation, such as receiving mail, sending mail, etc.;

In the steps S101 and S104, the same encryption algorithm may be used, preferably an asymmetric encryption algorithm, so as to improve the security of information transmission;

In addition, in the step S103, when the second server obtains the result of the mail operation, it can also store the result of the mail operation. When the next operation performed by the client needs to return to the previous operation page, the second According to the returned operation instruction, the server can directly return the saved last operation page to the client after being adapted, compressed and encrypted by the first server, so that each operation does not need to be performed through the mail server, or, When the user needs to read the content of the old mail, the second server can directly extract the content of the mail from the stored content according to the command to read the mail, and send it to the client after being compressed and encrypted by the first server , without the need to perform the operation of extracting mail from the mail server again, which improves the efficiency of mail operation, and can support automatic conversion and browsing of mail pages.

In the step S104, the adaptation process may include: adjusting the operation result returned by the mail server according to the screen size of the embedded device, so that the adjusted result is suitable for display on the embedded device, wherein the The adjustments made may include: removing unnecessary information in the above operation results, such as advertisement information, page footers, third-party plug-ins, etc.; rearranging the pages in the above operation results that are suitable for the embedded device, so that the pages The rearranged pages are convenient to display on embedded devices, including vertical browsing or horizontal browsing, and the rearranged pages can include corresponding menus and navigation functions; The controls displayed by the user do related processing suitable for embedded devices and so on.

In addition, in the step S102, if there are multiple second server ends, before forwarding the mail operation request, the first server first selects the corresponding second server end, and sends the mail operation request to The selection method of the selected second server may include: different second servers correspond to different user names, and the first server sends the mail operation request to the There is a second server with the user name; or, select the corresponding second server according to the name of the mail server of different mailbox types in the mail operation request, or, all the second servers can execute any type of mail server For the operation, the first server selects the appropriate second server according to the number or complexity of the current processing tasks of each second server, and preferentially selects the second server that is relatively idle to obtain a more efficient processing process.
