Description

Method of archiving email attachments and cloud storage server

Technical field

The present invention relates to the field of communications and, more particularly, to a method of archiving a mail attachment and a cloud storage server.

Background technique

Mail plays a very important role in daily work and business activities. In the process of mail communication, files are generally delivered as email attachments. Since email attachments generally include some important files, archiving email attachments on a regular basis has become a common practice for mail clients. In general, email attachments can be archived to the mail client local, mail server, or cloud storage server.

When an existing mail client archives a mail attachment, there are mainly two methods of archiving to the local and archiving to the cloud storage server. However, archiving email attachments locally, files are easily lost, and attachments are slower to retrieve. Due to limited storage capacity, the mail client also periodically cleans up locally cached email attachments. Then the user cannot retrieve or access the deleted file. And the mail attachments stored locally are easy to be snooped, and personal privacy cannot be well protected.

When an email attachment is archived to a cloud storage server, similar to the email attachment being archived locally, the mail client periodically cleans up the locally cached email attachments. When the user needs to find the attachment, the mail client preferentially retrieves from the local, and when the local search fails, the email attachment is retrieved from the cloud storage server, and the email attachment is downloaded from the cloud storage server. The method of archiving such email attachments to the cloud storage server avoids some local archiving, that is, the problem of mail client archiving, but its archiving efficiency is very low, which wastes the bandwidth consumption and system resources of the mail client. And when multiple mail clients archive the same email, the concurrent load and resource consumption of the mail server and the cloud storage server are increased.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 is a schematic flow diagram of a method of archiving an email attachment according to an embodiment of the present invention Figure. The method of Figure 1 is primarily performed by a mail client, a mail server, and a cloud storage server.

101. The mail client receives the target mail except for the target attachment of the target mail, and the rest of the target mail includes the mail header of the target mail.

The target mail is the new mail received by the mail client, and the target attachment is the attachment in the new mail. The target attachment entity is not included in the mail received by the mail client, and may only include information related to the target attachment entity.

It should be noted that if the mail received by the mail client does not have information related to the attached entity, the attachment archive is not required. Therefore, the embodiment of the present invention only describes the case where there is information related to the attachment entity in the mail.

102. The mail client obtains the mail identifier from the mail header of the target mail.

By parsing the message, you can get the message ID from the message header. The mail identifier corresponds to the target mail, that is, the unique target mail can be determined according to the mail identifier. The mail identifier may include information related to the target attachment, and the target attachment may be determined according to the information, or the target attachment may be directly determined according to the mail identifier.

103. The mail client sends the mail identifier and the cloud storage user information to the cloud storage server.

Cloud storage user information can be used to indicate cloud storage users. For example, the cloud storage user information may include an account and/or password of the cloud storage user.

The mail client can send the mail identifier and cloud storage user information by calling the archive interface of the cloud storage server. The archive interface of the cloud storage server can be the standard interface of the cloud storage server that has been defined.

104. The cloud storage server determines, according to the mail identifier, whether the target attachment is stored in the cloud storage server.

Optionally, as an embodiment, the cloud storage server may determine that the target attachment is not stored in the cloud storage server by determining an unstored mail identifier in the cloud storage server. That is to say, as long as there is no mail identifier in the cloud storage server, there is no target attachment in the cloud storage server. As long as there is a mail identifier in the cloud storage server, there is a target attachment in the cloud storage server.

In addition, the cloud storage server can also set the (attachment) archive corresponding to the mail identifier. status. The archive status indicates the archive status of the attachment, which can be both in the archive and in the archived case. Archived indicates that the attachment has been downloaded and stored in the cloud storage server; the archive is indicating that the attachment is being downloaded, and if the download is completed, the archive status is automatically updated to archived. However, regardless of the archival status, as long as there is an archive state in the cloud storage server, the cloud storage server does not need to store the target attachment.

105. When the cloud storage server determines that the target attachment is not stored in the cloud storage server, the cloud storage server sends the client user information and the attachment download request to the mail server.

The attachment download request can carry the email identifier. The client user information can be used to indicate a client user corresponding to the cloud storage user. The attachment download request may be used to request the mail server to send the target attachment corresponding to the mail identifier when the login authentication of the client user is successful.

Specifically, the cloud storage server searches for client user information of the client user corresponding to the cloud storage through the cloud storage user information, and sends the client user information and the attachment download request to the mail server, for example, sending the email server to the email server. The client user's account and password and the attachment download request. The mail server performs login authentication on the client user or the mail server determines whether the client user has successfully authenticated, and after the authentication succeeds or determines that the client user has successfully authenticated, sends the message according to the received cloud storage server. The message ID in the attachment download request finds the target message.

106. The mail server sends the target attachment to the cloud storage server according to the attachment download request.

The mail server can know the attachment that the cloud storage server needs to download according to the email identifier carried in the download request, that is, the target attachment, and send the target attachment to the cloud storage server after finding the target attachment.

107. The cloud storage server stores the target attachment and the email identifier in the cloud storage server.

After receiving the target attachment sent by the mail server, the cloud storage server stores the target attachment to the cloud storage server and stores the mail identifier.

In the embodiment of the present invention, the target attachment is stored in the cloud storage server, and when the target attachment is not stored in the cloud storage server, the target is directly downloaded from the mail server. Attachments, so that you do not need to go through the target attachment of the mail client, which can save the storage space and traffic bandwidth of the mail client.

In addition, downloading email attachments from the mail server does not provide a breakpoint download feature in most cases. If the network is interrupted or the program is abnormal during the download process, it is very likely that you will lose all your efforts and need to download again. The method for archiving an email attachment provided by the embodiment of the present invention has a breakpoint download function, which can cope with network instability or various abnormalities, can save traffic consumption and shorten download time to a certain extent, thereby improving user experience. .

Optionally, as an embodiment, as shown in FIG. 2, in 101, before the mail client receives the remaining part of the target mail except the target attachment of the target mail, the method may further include the following steps 201-205.

201. The mail client receives a first login request of the client user.

The first login request can carry client user information. The client user information may indicate the client user, and the client user information may include the account number and/or password of the client user.

202. The mail server performs first login authentication on the mail client according to the first login request.

In the embodiment of the present invention, login authentication is first performed on the mail client to verify the real identity of the mail client that issues the login request. In the login authentication, the mail server is used to authenticate the mail client. At this time, the mail server can use the previously saved account and the corresponding password to compare with the account of the client user carried in the login request and the password corresponding thereto, and carry the account and the login request saved before the mail server. When the account of the client user is the same, and the password of the account saved by the mail server and the password of the account of the client user carried in the login request are the same, the identity authentication can be passed, that is, the login authentication succeeds.

203. When the first login authentication succeeds, the mail client sends the cloud storage server to the cloud storage server. The second login request and client user information of the cloud storage user.

That is to say, after the mail server successfully authenticates the mail client, the cloud storage user makes a login request. The login request, that is, the second login request, carries cloud storage user information, and the cloud storage user information may include an account of the cloud storage user and a password corresponding thereto.

204. The cloud storage server performs login authentication on the cloud storage user.

After performing login authentication on the mail client, the embodiment of the present invention performs login authentication on the cloud storage user to verify the real identity of the cloud storage user who issues the login request. The cloud storage server used in the login authentication authenticates the cloud storage user. At this time, the cloud storage server can use the previously saved account and the corresponding password to compare with the account of the cloud storage user and the password corresponding to the login request, and the account and login request saved before the cloud storage server. When the account of the cloud storage user is the same, and the password of the account saved by the cloud storage server is the same as the password of the account of the cloud storage user carried in the login request, the identity authentication can be passed, that is, the authentication succeeds.

205. When the login authentication succeeds, the cloud storage server saves the cloud storage user information and the client user information correspondingly.

At the same time that the login authentication succeeds, the cloud storage server completes the binding of the client user and the cloud storage user. At the same time, the cloud storage server saves the binding relationship between the client user and the cloud storage user, that is, the cloud storage user information and the client user information can be saved correspondingly. At the same time, the mail client also stores cloud storage user information and client user information correspondingly.

After the first binding of the client user and the cloud storage user is completed, the cloud storage server automatically performs login authentication on the cloud storage user bound to the client user as long as the client user logs in to the mail client. In other words, as long as the client user successfully logs in, the cloud storage user will automatically log in to the cloud storage server.

FIG. 3 is a schematic flowchart of a method of archiving a mail attachment according to another embodiment of the present invention. The method shown in FIG. 3 can be executed by a mail server. The cloud storage server records the correspondence between the cloud storage account and the email account, and the cloud storage account and the email account are respectively the accounts registered by the user on the cloud storage server and the mail server.

310, receiving a mail identifier and a cloud storage account sent by the mail client, and the mail identifier The ID of the destination message received for the mail client.

Specifically, the cloud storage user information may be included in the step 103, and the cloud storage user information may include a cloud storage account. For brevity, details are not described herein again.

320. Determine, according to the email identifier, whether the target attachment corresponding to the target email is stored in the cloud storage server.

For details, refer to step 104 shown in FIG. 1 for details. For brevity, details are not described herein again.

330. When it is determined that the target attachment is not stored in the cloud storage server, determine a mail account corresponding to the cloud storage account.

340 Log in to the mail server according to the mail account.

350. Send a mail identifier to the mail server.

For details, the steps 105 to 350 may be specifically referred to the step 105 shown in FIG. 1 . For brevity, details are not described herein again.

360, download the target attachment from the mail server according to the mail identifier.

For details, refer to step 106 shown in FIG. 1 for details. For brevity, details are not described herein again.

370. Establish a correspondence between the target attachment and the email identifier.

Specifically, in this step, the corresponding relationship between the target attachment and the mail identifier can be established and saved in the steps 107 and 107 shown in FIG. 1 . For brevity, details are not described herein again.

Optionally, as an embodiment, the method may further include the following steps: the cloud storage server generates N file metadata and N files according to the N files in the target attachment. The metadata identifier ID, wherein the N files are in one-to-one correspondence with the N file metadata, the N file metadata and the N file metadata IDs are in one-to-one correspondence, N≥1; and the cloud storage server stores N file metadata IDs. And N file metadata, wherein the N file metadata IDs and the mail identifiers are corresponding storage locations.

In addition to the target attachment entity, the cloud storage server can also save file metadata (file description information) of files in the target attachment.

Table 1 below is an example of file metadata in the target attachment. It should be noted that the example of Table 1 is not restrictive, and the file metadata of the embodiment of the present invention is not limited thereto, and some fields may be deleted as needed, or other fields may be added.

Table 1 File metadata

序号Serial number	字段Field	字段描述Field description
11	文件IDFile ID	文件的唯一标识Unique identifier of the file
22	文件名file name	文件名称file name
33	文件大小File size	文件的大小File size
44	文件类型file type	文件的类型Type of file
55	更新时间Update time	文件内容的更新时间Update time of file content
66	路径path	文件的存储路径File storage path

In addition, each file metadata corresponds to a file metadata ID, and the cloud storage server stores the file metadata together with the mail identifier and the storage file metadata ID. For example, the cloud storage server may store the correspondence between the mail identifier and the file metadata ID in the form of a table. In this way, according to the stored mail identifier, the file metadata ID can be found, and the corresponding file metadata can be found.

Optionally, as an embodiment, the method may further include: when the cloud storage server determines that the target attachment is stored in the cloud storage server, the cloud storage server acquires a file metadata identifier ID corresponding to the mail identifier according to the mail identifier; The storage server acquires file metadata corresponding to the file metadata ID according to the file metadata ID; the cloud storage server stores the file metadata to a storage space of the cloud storage account of the file metadata. The cloud storage account does not store the file metadata before, and belongs to the first save. In fact, only Need to save once.

When the cloud storage server determines that the target attachment is already stored in the cloud storage server, it is no longer necessary to download the target attachment from the mail server, but only needs to find the file metadata of the file in the target attachment, and copy the metadata. Share it to your account, that is, the cloud storage account. For example, the cloud storage server may pre-store the correspondence between the mail identifier and the file metadata ID in a form of a table. When the cloud storage server needs to find the file metadata, the file metadata ID corresponding to the mail identifier may be found according to the mail identifier, and the corresponding file metadata may be found according to the file metadata ID. The file metadata is then stored to the storage space of the cloud storage account.

Alternatively, the file metadata may include an owner identification ID. Then, after the cloud storage user copies the file metadata, the owner ID in the file metadata can be changed to its own ID, and the other file metadata remains unchanged.

In the embodiment of the present invention, when different client users receive the same email, the cloud storage server only needs to download the target attachment from the mail server, and by setting the file metadata reference relationship, multiple client users can be implemented. Share the goal. Thereby, the network bandwidth, storage space and system resource consumption of the mail client can be saved.

It should be noted that when different client users receive the same email, only the first request to invoke the archive interface, that is, the client user who first archives the email, will trigger the cloud storage server to download the attachment from the mail server. And the action of generating file metadata.

Optionally, as an embodiment, the method may further include: the mail client acquires an operation of the client user; the mail client generates an access request corresponding to the operation according to the operation, and the access request is used to request access to the N stored by the cloud storage server. Part or all of the data information of at least one of the files; the mail client sends an access request to the cloud storage server; and the mail client receives part or all of the data of at least one of the N files sent by the cloud storage server according to the access request information.

Client users can access files saved by the cloud storage server, such as online preview or download. For example, a client user can access a file in a file list of a mail client, and the file list can be a client user saved by the cloud storage service. The file name of the file is also composed of the keywords of the file.

For example, in the embodiment of the present invention, the client user performs a double-click operation on a file name in the file list. At this time, the mail client can generate an access request corresponding to the operation according to the operation, and send the request to the cloud storage server. . The cloud storage server searches for the data information in the file according to the access request, and sends the data information in the file to the mail client.

It should be noted that the client user may only need to view some content (data information) in the file, then the online preview function of the cloud storage server may be utilized, and the content in the file may be viewed without downloading the entire file. In this way, the traffic consumption of the mail client can be saved.

It should also be noted that when the mail client needs to retrieve the mail attachment, the file retrieval interface (standard interface) of the cloud storage server can be directly called, and the file browsing interface can be used for file browsing or downloading.

The method for archiving an email attachment according to an embodiment of the present invention is described in detail above with reference to FIG. 1 to FIG. 3, and a cloud storage server according to an embodiment of the present invention will be described in detail below with reference to FIG.
