[0028] Embodiments of the present embodiment will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present embodiment are shown in the accompanying drawings, it should be understood that the present embodiment can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein, which are instead provided for a more thorough and complete understanding of the present embodiment. It should be understood that the drawings and embodiments of the present embodiment are only for exemplary purposes and are not intended to limit the scope of protection of the present embodiment.

[0029] In order to better understand the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained as follows:

[0030] Linked list: is a common data structure, which consists of a series of nodes, each node contains a data part and a reference (i.e. pointer) to the next node. The main feature of the linked list is its dynamic nature, which allows easy insertion and deletion of elements without reallocating memory or moving large amounts of data like an array.

[0031] Node: Each element in a linked list is called a node. A node usually consists of two parts: a data field and a pointer field. The data field is used to store actual data. The pointer field is used to store a pointer to the next node.

[0032] Head node: The first node of a linked list, usually accessed through a pointer (such as head).

[0033] Tail node: The last node of a linked list, whose pointer field is usually NULL.

[0034] Doubly linked list: Each node has two pointer fields, one pointing to the previous node and the other pointing to the next node. It can be traversed in both directions, and the insertion and deletion operations are more flexible.

[0035] In the related art, when the mail client performs the above operations, the data synchronization efficiency between the mail client and the server is relatively low, and it is impossible to quickly determine whether there are new mails on the server, and it is impossible to quickly locate the mails to be deleted on the server, resulting in poor performance of the mail client, which in turn affects the user experience. In order to solve this problem, the embodiments of the present application provide a related solution, which is described in detail below.

[0036] Figure 1 is a flowchart of an email operation method according to an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0037] Step S102: receiving an instruction sent by the mail client to operate the target mail.

[0038] An email client is a software application used to send, receive, and manage emails. It provides a user interface that enables users to easily interact with an email server.

[0039] According to an optional embodiment of the present application, the above instructions include but are not limited to operations such as querying and obtaining new emails from the server and deleting emails.

[0040] In this step, the execution subject is the server, which receives instructions sent by the mail client to perform relevant operations on the target mail.

[0041] Step S104, in response to the instruction, searching for the target email in the linked list of the server, wherein each email is stored in the form of a linked list in both the server and the email client, and each node in the linked list is used to store an email, an identification number of the email, an identification number of the previous email, and an identification number of the next email.

[0042] In an embodiment of the present application, the mail client and the server both store each mail in the form of a linked list, and use the SM3 algorithm to calculate the unique identifier of the mail, Mail ID; and record the ID of the previous mail and the ID of the next mail of this mail.

[0043] ‌SM3 algorithm is a cryptographic hash function, the full name is "National Cryptography Administration Announcement No. 3 Cryptographic Hash Algorithm". It is a one-way cryptographic system that can only perform encryption process but no decryption process. The main function of SM3 algorithm is to convert input data of any length into output data of fixed length, usually a 256-bit hash value. The calculation process of this hash value is irreversible, which means that the original input data cannot be restored from the hash value.

[0044] Figure 2is a schematic diagram of the structure of a link list in a mail client and a server according to an embodiment of the present application, such as Figure 2 As shown, both the email client and the server store data in the form of linked lists. The data field of each node in the double linked list is used to store the email body and the identification ID of the email, and the two pointer fields of each node are used to store the identification ID of the previous email and the identification ID of the next email.

[0045] Step S106: executing the operation corresponding to the instruction on the target email.

[0046] The above method provided in the embodiment of the present application stores each email, the email identification number, the identification number of the previous email, and the identification number of the next email in the form of a linked list in the email client and the server. When the email client performs the operation of searching for new emails or deleting emails, it searches the email identification number stored in the linked list, thereby achieving the purpose of quickly searching whether there are new emails on the server and quickly locating the emails that need to be deleted, thereby achieving the technical effect of improving the data synchronization efficiency between the email client and the server and improving the performance of the email client.

[0047] According to an optional embodiment of the present application, if the instruction is to obtain a new email from the server, step S104 is executed to search for the target email in the linked list stored on the server, including the following steps: obtaining the first email identification number stored in the tail node of the linked list sent by the email client; comparing the second email identification number stored in the tail node of the linked list on the server with the first email identification number; if the first email identification number is the same as the second email identification number, determining that no new email is stored in the server; if the first email identification number is different from the second email identification number, determining that a new email is stored in the server, and determining the new email as the target email.

[0048] Whether it is the email client or the server, the latest email is stored in the tail node of the linked list. Therefore, when the email client queries and obtains new emails from the server, it uses the email ID (latest email) stored in the tail node of the linked list to ask the server. The server compares the email ID stored in the tail node of its linked list with the email ID sent by the email client. If the two are the same, the server has no new email; if the two are different, the server has new email. If the server has new emails, the server needs to push the new emails to the client.

[0049] like Figure 2 As shown, the email client uses the latest email ID number 4 recorded in Table 1 to query the server whether there is a new email. The server compares the latest email ID number 5 recorded in Table 1 with the email ID number 4 sent by the client. If the two are different, it means that the server has a new email.

[0050] According to another optional embodiment of the present application, step S106 is executed to execute the operation corresponding to the instruction on the target email, including the following steps: searching for the corresponding email in the linked list on the server side according to the first email identification number; determining the identification of the next email in the node storing the email corresponding to the first email identification number as the identification number of the target email; searching for the target email in the linked list on the server side according to the identification number of the target email; and sending the target email and the identification number of the target email to the email client.

[0051] The server queries the corresponding email stored on the server according to the email identification ID sent by the email client (i.e. the first email identification number mentioned above); the server queries the next email according to the ID of the next email pointed to by the corresponding email; the server returns the body and ID of the next email to the email client.

[0052] like Figure 2 As shown, the server searches for the corresponding email according to the latest email ID 4 of the email client. The node recording the email also records the ID 5 of the next email. The next email (the target email mentioned above, i.e. the latest email of the server) is found according to the ID 5 of the next email, and then the server returns the email with ID 5 to the email client.

[0053] As some optional embodiments of the present application, after sending the target email and the identification number of the target email to the email client, the email client modifies the identification number of the next email in the node storing the first email identification number in its linked list to the identification number of the target email; the email client inserts the target email and the identification number of the target email into its linked list, and modifies the identification number of the previous email in the node storing the target email to the identification number of the first email.

[0054] After receiving the latest email returned by the server, the email client inserts the new email body and the new email ID into the linked list, updates the linked list, and modifies the Next Email field in the node storing the original email to point to the ID of the new email (i.e. the ID of the target email mentioned above). The Previous Email field in the node storing the new email is modified to point to the ID of the original email (i.e. the ID of the first email mentioned above).

[0055] like Figure 2 As shown, after receiving the email with email ID 5 (hereinafter referred to as email No. 5), the email client modifies the node storing email No. 4, and changes the ID of the next email stored therein to 5. Then, the email client inserts email No. 5 and changes the ID of the previous email in the node storing email No. 5 to 4. Finally, the email client updates the ID of the latest email to 5. Through the above series of steps, the email client completes a process of querying and obtaining new emails from the server.

[0056] like Figure 2 As shown, the latest email ID on the server is 8. Similarly, the email client uses email No. 5 to query the server for new emails. The logic is the same as querying email No. 4 and inserting email No. 5. Until the email client obtains email No. 8 from the server, the entire query process ends.

[0057] According to an optional embodiment of the present application, if the instruction is to delete the target email from the server, execute step S106 to perform the operation corresponding to the instruction on the target email, including the following steps: search for the previous copy of the target email in the linked list of the server, and modify the data in the node in the linked list of the server for storing the previous copy of the target email; search for the next copy of the target email in the linked list of the server, and modify the data in the node in the linked list of the server for storing the next copy of the target email; delete the target email in the linked list of the server.

[0058] When the email client sends an instruction to the server to delete an email, the email client sends the email identification ID to be deleted to the server. The server queries the corresponding email based on the email identification ID, and then queries the next email and the previous email based on the corresponding email, and modifies the data in the nodes storing the next email and the previous email respectively.

[0059] As an optional embodiment of the present application, searching for the previous copy of the target email in a linked list on the server side, and modifying the data in the node in the linked list on the server side for storing the previous copy of the target email, is achieved by the following method: searching for the identification number of the previous copy of the target email in the node storing the target email in the linked list on the server side; determining the previous copy of the target email based on the identification number of the previous copy of the target email; and modifying the identification number of the next email stored in the node storing the previous copy of the target email from the identification number of the target email to the identification number of the next email stored in the node storing the target email.

[0060] like Figure 2 As shown in the figure, the email client wants to delete email No. 2. The server finds the corresponding email based on email ID 2, and then finds the previous email of email No. 2 (i.e., email No. 1). The ID of the next email in the node storing email No. 1 is changed from 2 to 3 (because email No. 2 no longer exists after it is deleted).

[0061] As an optional embodiment of the present application, searching for the next copy of the target email in a linked list on the server side, and modifying the data in the node in the linked list on the server side for storing the next copy of the target email, includes the following steps: searching for the identification number of the next copy of the target email in the node storing the target email in the linked list on the server side; determining the next copy of the target email according to the identification number of the next copy of the target email; and modifying the identification number of the previous copy of the email stored in the node storing the next copy of the target email from the identification number of the target email to the identification number of the previous copy of the email stored in the node storing the target email.

[0062] like Figure 2 As shown in the figure, the email client wants to delete email No. 2. The server finds the corresponding email based on email ID 2, and then finds the next email of email No. 2 (i.e., email No. 3). The ID of the previous email in the node storing email No. 3 is changed from 2 to 1 (because email No. 2 no longer exists after it is deleted). Finally, email No. 2 is deleted on the server.

[0063] The above solution proposed in this application can quickly retrieve whether there are new emails on the email server and quickly locate and delete emails, which greatly improves the performance of the email client.

[0064] Figure 3 is a flowchart of another email operation method according to an embodiment of the present application. Figure 3 As shown, the method comprises the following steps:

[0065] Step S302, sending an instruction to obtain a new email and the first email identification number stored in the tail node of the linked list of the email client to the server, wherein the server and the email client both store each email in the form of a linked list, and each node in the linked list is used to store an email, an email identification number, an identification number of the previous email, and an identification number of the next email.

[0066] Step S304, receiving a target email and an identification number of the target email sent by the server, wherein the target email is a new email.

[0067] According to an optional embodiment of the present application, after executing step S304 to receive the target email and the identification number of the target email sent by the server, the identification number of the next email in the node storing the first email identification number in the linked list of the email client is modified to the identification number of the target email; the target email and the identification number of the target email are inserted into the linked list, and the identification number of the previous email in the node storing the target email is modified to the first email identification number.

[0068] It should be noted that the execution subject of step S302 to step S304 is the mail client. Figure 3The illustrated embodiment shows the steps performed by the email client in the process of querying and obtaining new emails from the server. Figure 3 The preferred implementation of the embodiment shown can be referred to Figure 1 The relevant description of the illustrated embodiment will not be repeated here.

[0069] Figure 4 is a flowchart of another email operation method according to an embodiment of the present application. Figure 4 As shown, the method comprises the following steps:

[0070] Step S402, sending an instruction to delete the target email to the server, wherein the server and the email client store each email in the form of a linked list, and each node in the linked list is used to store an email, an email identification number, an identification number of the previous email, and an identification number of the next email.

[0071] Step S404: search for the previous copy of the target email in the linked list of the email client, and modify the data in the node for storing the previous copy of the target email in the linked list of the email client.

[0072] Step S406, searching the linked list of the mail client for the next copy of the target mail, and modifying the data in the node for storing the next copy of the target mail in the linked list of the mail client.

[0073] Step S408: Delete the target email from the linked list of the email client.

[0074] According to an optional embodiment of the present application, step S404 is executed to search for the previous copy of the target email in the linked list of the email client, and the data in the node for storing the previous copy of the target email in the linked list of the email client is modified, including the following steps: searching for the identification number of the previous copy of the target email in the node storing the target email in the linked list of the email client; determining the previous copy of the target email based on the identification number of the previous copy of the target email; and modifying the identification number of the next email stored in the node storing the previous copy of the target email from the identification number of the target email to the identification number of the next email stored in the node storing the target email.

[0075] According to an optional embodiment of the present application, step S406 is executed to search for the next copy of the target email in the linked list of the email client, and the data in the node used to store the next copy of the target email in the linked list of the email client is modified, including the following steps: searching for the identification number of the next copy of the target email in the node storing the target email in the linked list of the email client; determining the next copy of the target email according to the identification number of the next copy of the target email; and modifying the identification number of the previous email stored in the node storing the next copy of the target email from the identification number of the target email to the identification number of the previous email stored in the node storing the target email.

[0076] It should be noted that the execution subject of steps S402 to S408 is the mail client. Figure 4 The illustrated embodiment shows the steps performed by the email client during the process of deleting emails. Figure 4 The preferred implementation of the embodiment shown can be referred to Figure 1 The relevant description of the illustrated embodiment will not be repeated here.
