[0126] Please refer to Figure 4 , Figure 4 The application provided for the embodiment of this application image 3 The flow chart of the mail data storage method of the electronic device 300, the steps included in the method will be described in detail below.

[0127] Step S401, obtaining emails to be stored. The mail includes a mail header and a mail body, the mail body includes at least one atomic segment, and each atomic segment includes a segment header and a segment body.

[0128] Each atomic segment body in the email body expresses a piece of data, which can be text, images, audio, attachments, etc. The atomic segment body data are independent of each other and have no relationship. There are a lot of repeated information in emails on the Internet. Different emails may contain the same picture and the same document, which means that different email bodies contain the same atomic segment body.

[0135] The embodiment of the present application provides a method for storing mail data on the mail server 100 . In this embodiment of the application, the situation of mail data storage can be that the mail server 100 receives a mail and saves it to the user's inbox, or that the mail server 100 saves a copy of the mail to the user after sending the mail. The mailbox can also be the user draft mailbox in which the mail client 200 uploads the draft mail to the mail server 100 after writing the draft mail.

[0136] Please refer to Figure 5 , Figure 5 The application provided for the embodiment of this application figure 2 A flowchart of a method for storing mail data in the mail server 100.

[0137] Step S501, calculating the mail data identifier of the mail to be stored.

[0138] Calculate the mail data identifier of the mail to be stored according to the mail header and mail body of the mail to be stored, wherein the mail header includes the mailbox identifier.

[0163] This embodiment provides a method for downloading and viewing mails on the basis of storing mail data in the manner in the second embodiment. In this embodiment, the way of downloading and viewing mails can be downloading mails in the Mail in the outbox or download mail in the draft box, etc.

[0164] Please refer to Image 6 , Image 6 A schematic flow chart of downloading emails is shown, and the specific flow will be introduced below.

[0165] Step S601, receiving a download request for downloading emails in a mailbox.

[0166] When the user downloads mail from the mail server 100 through the mail client 200, the mail server 100 will transmit the mail data to the mail client 200 through the POP3 protocol or the IMAP protocol, and then the mail client 200 stores the mail data in the user's local storage space.

[0167] Step S602, according to the mailbox identifier of the mailbox, look up the mail data identifier of the mail to be downloaded in the mailbox mail re...

Abstract

In the mail data storage method and device provided by the present application, in the method, first, calculate the segment body identification of each atomic segment in the mail to be stored; then, use the segment body identification to replace the atomic segment body in the mail to be stored, and obtain the compression mail data, and store the mail data; finally, detect whether the atomic segment body in the mail to be stored has been stored in the electronic device, and save the atomic segment body not stored in the electronic device into the electronic device according to the detection result. Compared with the existing technology that stores the mail as a whole to be stored, the storage granularity of storing the mail body as an atomic segment body is smaller, and the same atomic segment in the mail body of different mails can be stored in the process of mail data storage. The body is only stored once, which can reduce the storage redundancy of mail data storage and save storage resources.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular, to a method and device for storing mail data. Background technique [0002] E-mail is one of the most commonly used means of communication in people's daily life and office. An email transmitted over the Internet is essentially a piece of data. [0003] When using e-mail for communication, the sent or received e-mail data will be stored for the convenience of users to view at any time. However, when mail data is stored, most of the existing mail data storage methods store different mails separately. There will be storage redundancy and the disadvantage of occupying more storage resources. Contents of the invention [0004] In view of this, one of the purposes of the present application is to provide a mail data storage method and device to solve the existing technical problems of high storage redundancy and occupying more storage resources when storing mail ...
