Description

Mail downloading method and terminal

Technical Field

The invention relates to the technical field of computers, in particular to a method and a terminal for downloading mails.

Background

Currently, a mailbox client mainly uses an Internet Message Access Protocol (IMAP), and when a mail is downloaded through the IMAP, especially under the condition of a large number of mails, the mail downloading speed is easily caused, which is specifically a disadvantage as follows:

when a local mailbox acquires a mail information list in a mail updating time period, the mail updating end time is not the end time directly acquired from a server, but the mail updating end time calculated according to the time format of coordinated universal time UTC, such as the mail updating end time (UTC) = the mail updating end time (Chinese district server time) -8.

Therefore, when the user refreshes the mails, especially under the condition of a large number of the mails, the downloading speed of the new mails is low, and the user can load all the new mails after waiting for a long time, thereby seriously influencing the user experience.

Disclosure of Invention

The invention provides a method and a terminal for downloading a mail, which are used for overcoming the defect of low downloading speed when the mail is downloaded through an IMAP protocol, improving the speed of downloading the mail and improving the experience of a user using a mailbox client.

In a first aspect, the present invention provides a method for downloading an email, including:

responding to the mail updating instruction, taking the current local time of the terminal as the starting time of the mail updating, and taking the local downloading time of the earliest mail in the current mail list as the finishing time of the mail updating, and determining a mail updating time period;

acquiring the mail information in the updating time period from a server;

and downloading the mail information in the updating time period according to the downloaded mail information in the current mail list.

In the method for downloading the mails, when determining the end time of the mail update, a time zone factor is considered, the end time of the mail update is not calculated according to the time format of coordinated Universal Time Coordinated (UTC), but the local download time of the earliest mail in a current mail list acquired by a terminal from a server is taken as the end time of the mail update, so that the end time of the mail update in the embodiment is calculated according to the local time, because the start time of the mail update is calculated according to the local time of the current mail client, the mail download method provided by the application can acquire the more accurate end time of the mail update, thereby acquiring the more accurate mail update time period, avoiding the defect that the mail update time period is increased due to the time zone factor, and the mail information in the update time period acquired from the server avoids acquiring the downloaded mail information of a mailbox client, therefore, under the condition that the number of the mails needing to be updated is large, the downloading speed of the mails can be greatly improved, the long-time waiting of a user is avoided, and the use experience of the user is improved.

In an optional implementation manner, downloading the mail information in the update time period according to the downloaded mail information in the current mail list includes:

and simultaneously starting a plurality of threads in the thread pool, and individually downloading the mail information in the updating time period through each thread according to the downloaded mail information in the current mail list.

The method for starting the multithreading downloading overcomes the defect of one package of the existing downloading, and can further improve the speed of downloading the mail under the condition of abundant data transmission bandwidth.

In an optional implementation manner, downloading the mail information in the updated time period according to the downloaded mail information in the current mail list, further includes:

and responding to a specified mail downloading instruction, and starting an independent thread outside the thread pool to download the specified mail.

Furthermore, the method can ensure that the thread in the thread pool is not occupied, the independent thread is adopted to download the designated mail independently, the user can be ensured to download the designated mail independently in a targeted manner, and particularly in the process that the designated mail is waiting for downloading, the independent thread can be used to download the designated mail quickly by responding to the downloading instruction of the user to the designated mail, so that the waiting time of the user is avoided, and the use experience of the user can be improved.

In an optional embodiment, the method further comprises:

and after responding to the mail updating instruction, if the number of the mails in the current mail list exceeds a preset value, deleting the mails according to the sequence of the mail downloading time in the current mail list until the number of the mails does not exceed the preset value.

In the process of downloading the mail according to the IMAP protocol, header information of the mail in the update time period, such as a mail header, a sender and the like, is downloaded first, the flag bits of the mails in the current mail list, such as read or unread mails, important mails, replied mails, etc., when the flag bit is updated, whether the number of mails in the current mail list exceeds 500 is judged, if so, 500 is taken as a segment, the flag bit updating application is initiated to the server in segments, the initiated update flag bit application is time-consuming, about 0.5 seconds is needed for each time of initiating the application command, therefore, further, by the method, the mails can be automatically deleted, the number of the mails is ensured not to exceed the preset value, the application times of updating the zone bit are reduced to a certain extent, therefore, the time for initiating the updating of the zone bit is saved to a certain extent, and the speed of downloading the mail is improved to a certain extent.

In an optional implementation manner, after deleting the mails in sequence until the number of the mails does not exceed a preset value, the method further includes:

and responding to the instruction of viewing the mails, sending the number of the viewed mails and the local downloading time of the earliest mail in the current mail list to the server, and acquiring the number of mails before the local downloading time from the server.

The method can ensure that on the basis of an automatic mail deleting mechanism, even if a user wants to acquire mails of which the number exceeds that of the mails in the current mail list, the number of the mails to be checked and the starting time of checking can be still sent to the server, and the mails to be checked are acquired from the server and stored in the current mail list.

In a second aspect, the present invention provides a terminal for downloading a mail, the terminal comprising: a processor and a memory, wherein the memory stores program code that, when executed by the processor, causes the terminal to perform the following:

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Some of the words that appear in the text are explained below:

1. the term "terminal", or "terminal device", in the embodiment of the present invention, is a device located at the outermost periphery of a network in a computer network, and can access a wireless local area network WLAN to perform input of user information and output of processing results, and includes a desktop computer, a mobile phone, a notebook, a tablet computer, a POS machine, and a vehicle-mounted computer.

2. In the embodiment of the invention, the term "coordinated universal time UTC" is also called universal time, universal standard time and international coordinated time. The coordinated universal time is a time metering system which is based on the length of atomic hour and second and is as close to the universal time as possible in time. The set of time systems is used in many standards for the internet and world wide web, for example, the network time protocol is one way to coordinate the use of the world time in the internet. The time difference between UTC and time in china (including hong kong, australia, taiwan), mongolia, singapore, malaysia, philippines, western australia is +8, i.e., UTC + 8.

The execution main body of the invention is a terminal which comprises a mailbox client or other application programs capable of downloading the mail, and a user can acquire the mail through the mailbox client and perform corresponding operations on the mail, such as downloading, deleting and the like. As shown in fig. 1A, the terminal display page displays a mailbox client, and as shown in fig. 1B, the mailbox client includes a plurality of function options such as an inbox, a sent mail, a deleted mail, an important mail, a draft box, a recycle bin, a collected mail, and a collected contact, wherein as shown in fig. 1C, after the user clicks the inbox function, a mail list can be displayed, and downloaded mail information is displayed in the mail list.

The application scenario described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by a person skilled in the art that with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems.

Currently, a mailbox client mainly uses an Internet Message Access Protocol (IMAP), where the IMAP is a Protocol for specifying how a personal computer accesses a mail server on the Internet to send and receive mails, and supports the mailbox client to Access and read mails on the server online or offline, and also can interactively operate mails on the server and provide a user-oriented mail download service. The user can decide whether to download, delete and retrieve a specific part of the mail by browsing the mail header information, and the user is provided with a function of selectively receiving the mail from the mail server.

The IMAP provides two-way communication between the mail on the server and the mailbox client, the operation of the mailbox client synchronously reacts to the server, the operation is carried out on the mail, and the mail on the server also performs corresponding action. For example, 3 mails in the mailbox are downloaded at the mailbox client, one of the three mails is marked as read, the other two mails are marked as deleted, and the operations are fed back to the server immediately.

The IMAP protocol supports an off-line mode and an on-line mode to transmit data, and in the on-line mode, a mail box client operates a mail on a server, so that the mail does not need to be downloaded to the local, and a user can browse the mail through the mail box client or the Wed on line; in the off-line mode, the mailbox client can continuously connect the server to download unread mails to the local disk.

As shown in fig. 2, a brief introduction is made to the flow of the mail downloading process by the existing IMAP protocol:

step 200, taking the current time as the starting time of the mail updating, and determining the ending time of the mail updating, wherein the current time is calculated according to the current local time, and the ending time is calculated according to the time format of UTC;

and if the end time of the mail updating of the account which is just created is the time obtained by subtracting 1 day from the current time, and if the account is not the account which is created for the first time, the end time of the mail updating is the UTC time of the earliest mail in the current mail list.

Step 201, acquiring mail list information from a server in a time period from the current time to the end of the mail updating, wherein each mail comprises identification information Remote access identifier (UID);

step 202, obtaining mail list information in a Local mail list, wherein each mail comprises identification information Local UID;

step 203, comparing whether the identification information Remote User Identifier (UID) is consistent with the identification information Local UID, if so, executing step 204, otherwise, executing step 205;

step 204, determining that the mail corresponding to the identification information is downloaded locally, and not executing the downloading of the mail;

step 205, judging whether the Local UID is null or not and whether the Remote UID is not null or not, if the Local UID is null and the Remote UID is not null, executing step 206, and if the Local UID is not null and the Remote UID is null, executing step 207;

step 206, determining that the mail corresponding to the identification information is not downloaded to the local, and adding the mail into a mail list which is not downloaded;

step 207, determining that the mail corresponding to the identification information is deleted at the server side, and deleting the mail locally;

step 208, downloading the mail header information in the undelivered mail list;

step 209, refreshing the zone bit of the mail in the local mail list;

the flag bits include, but are not limited to, read, unread, important mail, advertised mail, replied.

If the current local mail exceeds 500, taking 500 mails as a section, and sending a flag bit updating application to the server in a segmented manner; if the local mail is less than 500, initiating an application to the server through a command.

And step 210, downloading the mails in the undelivered mail list one by one in sequence.

Through the above simple introduction of the mail downloading process in the prior art, it can be seen that the following time-consuming operations are available in the mail downloading process:

when the local mailbox client side obtains the mail information list in the updated time period, the end time of the mail update is calculated according to the time format of UTC, and the start time of the mail update is calculated according to the current local time, for example, the SERVER timestamp (SERVER _ TIMESTAMP) of the last mail of the local mailbox client side is 2017-08-0607: 00:00, if the SERVER timestamp (SERVER _ TIMESTAMP) is 2017-08-0523: 00:00 after being converted into UTC time (time zone 8 hours is removed), the end date of the mail update is 2017-08-05, when a refreshing operation is initiated, all mails of 2017-08-05 are refreshed as new mails, the process of downloading the mails is a time-consuming operation, and the mail refreshing speed and the downloading speed are slow on a mailbox client side interface.

Aiming at the defects, the invention provides a mail downloading method, which can improve the speed of downloading the mail and improve the experience of a user in using a mailbox client.

Example 1

The following describes a method for downloading a mail according to the present invention by using a specific embodiment.

In order to improve the defect of slow downloading speed when the mails are downloaded through an IMAP protocol, the embodiment of the invention mainly optimizes the end time for determining the mail updating time, directly takes the time of the earliest mail in the current mail list as the end time of the mail updating, does not take the UTC time of the earliest mail in the current mail list as the end time of the mail updating, calculates the start time and the end time of the mail updating according to the local time, avoids the inaccuracy of the mail updating end time caused by a time zone, and can improve the mail downloading speed, particularly improve the use experience of a user when a large number of mails are downloaded.

As shown in fig. 3, the method for downloading an email provided in this embodiment includes the following specific implementation flows:

and step 300, responding to the mail updating instruction, taking the current local time of the terminal as the starting time of the mail updating, and taking the local downloading time of the earliest mail in the current mail list as the ending time of the mail updating, and determining the mail updating time period.

In this embodiment, determining that the mailbox client responds to the mail update instruction includes, but is not limited to, the following manners:

mode 1, when determining that a mailbox client is started, responding to a mail updating instruction; that is, the email update is started at the moment when the email client is started, as shown in fig. 4A, after the user clicks the email client, the email client is started and responds to the email update instruction.

Mode 2, when determining that the trigger updating instruction is received, responding to the mail updating instruction; specifically, the trigger update instruction may be determined to be received when the user clicks the refresh or load option of the mailbox client, as shown in fig. 4B, after the user clicks the refresh or load option of the mailbox client, the email update instruction is responded.

And 3, responding to the mail updating instruction when the set time is determined to be reached. The mailbox client automatically initiates the mail updating indication in the background every set time.

In this embodiment, the mailbox client determines that the start time and the end time of the email update are determined according to the local time, so as to notify the server of acquiring the email information in the time period, and specifically may determine the time period for email update in the following manner:

mode 1, if the account is a mailbox account which is just created, the start time of updating the mail is the current time, the end time of updating the mail is the time obtained by subtracting 1 day from the current time, that is, the end time of updating the mail = the local download time of the earliest mail in the current mail list = the current local time of the terminal-1 day, and the time period of updating the mail = the current local time of the terminal-the local download time of the earliest mail in the current mail list of the terminal =1 day, so if the account is a mailbox account which is just created, the mail information before one day is acquired from the server;

and 2, if the mail is not the newly created mailbox account, determining the mail updating time period by taking the current local time of the terminal as the starting time of the mail updating and taking the local downloading time of the earliest mail in the current mail list as the finishing time of the mail updating. And taking the current local time of the terminal as the start time of mail updating, and taking the server time of the last mail acquired by the terminal from the server, namely the local downloading time of the earliest mail in the current mail list, as the end time of mail updating, namely the time period of mail updating = the current local time of the terminal-the local downloading time of the earliest mail in the current mail list of the terminal.

If the current local time of the terminal (namely the current time of the local mailbox client) is 2019-7-2912: 00:00, the local downloading time of the earliest mail in the current mail list of the terminal, namely the server time of the last mail acquired from the server by the local mailbox client is 2019-7-297: 00:00, the time period for updating the mail is 2019-7-2907: 00: 00-12: 00:00, and all mail information in the time period is acquired from the server.

In the embodiment, when the time zone factor is considered and the UTC time is not used for calculation, the mail information which does not need to be updated is also prevented from being downloaded, and the speed of downloading the mail is increased.

For another time-consuming operation in the current mail downloading process, when the number of local mails is large, such as more than 1000, updating flag bit application is initiated to the server in segments, such as 500 mails are taken as one segment, but each time of initiating an application command requires about 0.5 second, when the number of local mails is far more than 1000, the application command is initiated for multiple times, and if N (N is a positive integer) times of application commands are initiated, N x 0.5 seconds are additionally required, so that the time consumption is long; to improve this time consuming operation, embodiments of the present invention provide the following:

as a possible implementation manner, after responding to the mail update instruction, if the number of mails in the current mail list exceeds the preset value, the embodiments of the present invention delete the mails according to the sequence of the mail download time in the current mail list until the number of mails does not exceed the preset value.

Optionally, the preset value is a value not greater than 1000, for example, the preset value =1000, if the number of the mails in the local mailbox client exceeds 1000, the mails are deleted according to the sequence of the download time until the number of the local mails is within 1000, so that the mail refreshing operation can be completed only by sending a command of refreshing the flag bit twice at most.

As an optional implementation manner, the emails are deleted until the number of the emails does not exceed the preset value, and the deletion may also be performed according to the priority, the importance degree, or the type of the email, for example, the emails with the type of the email being an advertisement type, the emails with the lowest priority of the emails, or the unimportant emails marked by the user may be preferentially deleted.

If the user needs to check the mails beyond the preset value, the embodiment also provides the following method for checking:

as a possible implementation manner, in response to the instruction of viewing the mails, the number of the viewed mails and the local download time of the earliest mail in the current mail list are sent to the server, and the number of the mails before the local download time are obtained from the server.

For example, the user needs to view the mails of other than the latest 1000 mails, as shown in fig. 4C, the user may trigger to acquire more mails from the server by clicking the "load more mail" button, and display the mails in the mail list of the local mailbox client; when the user refreshes the mails next time, the above mail deleting mode can be adopted to determine that the mails in the local mailbox client exceed 1000 packages, and the mails are deleted according to the sequence of the downloading time until the number of the local mails is within 1000 packages.

In the process of downloading the mail by the IMAP protocol at present, header information of the mail in an updating time period, such as a mail title, a sender and the like, is downloaded first, then flag bits of the mail in a current mail list, such as a read mail, an unread mail, an important mail, a reply and the like, are refreshed, when the flag bits are updated, whether the number of the mails in the current mail list exceeds 500 is judged, if so, the mails are divided into one segment by 500, the application for updating the flag bits is initiated to a server in a segmented manner, and the initiated application for updating the flag bits takes time, and each time of initiating an application command needs about 0.5 second.

Therefore, further, by the method, the mails can be automatically deleted, the number of the mails is guaranteed not to exceed the preset value, the time for initiating the application of the update flag bit for many times is saved by the method for deleting the mails in the embodiment when the number of the mails exceeds 1000 in the prior art, and particularly when the number of the mails exceeds 1000, the method in the embodiment is adopted, the number of times for applying the update flag bit is reduced to a certain extent, so that the time for initiating the update flag bit is saved to a certain extent, the time for updating the mails is saved, and the speed for downloading the mails is improved to a certain extent.

Step 301, obtaining the mail information in the updating time period from the server.

And according to the time period of updating the mail determined by the terminal, after all mail information in the time period of updating is obtained from the server, according to the downloaded mail information in the current mail list, the mail information which is not downloaded by the terminal is determined from the mail information obtained by the server.

Specifically, as shown in fig. 5, the mail information that has not been downloaded by the terminal may be determined by the following steps:

step 500, acquiring mail list information from a server within a time period from the current time to the end of the mail updating, wherein each mail comprises identification information Remote access identification (UID);

step 501, mail list information in a Local mail list is obtained, wherein each mail comprises identification information Local UID;

step 502, comparing whether the identification information Remote UID is consistent with the identification information Local UID, if so, executing step 503, otherwise, executing step 504;

step 503, determining that the mail corresponding to the identification information is downloaded locally, and not executing the downloading of the mail;

step 504, judging whether the Local UID is null or not and whether the Remote UID is not null or not, if the Local UID is null and the Remote UID is not null, executing step 505, and if the Local UID is not null and the Remote UID is null, executing step 506;

step 505, determining that the mail corresponding to the identification information is a mail which is not downloaded by the terminal;

step 506, if the mail corresponding to the identification information is determined to be deleted at the server side, the mail is locally deleted.

And 507, downloading the mail information in the updating time period according to the downloaded mail information in the current mail list.

Further, as a possible implementation manner, in the present embodiment, an asynchronous multithreading manner is adopted for the yet-to-be-downloaded mail, that is, multiple threads in a thread pool are simultaneously started, and mail information is separately downloaded through each thread according to the downloaded mail information in the current mail list, in the present embodiment, multiple threads are simultaneously started, each thread separately starts downloading of mail content, if a certain thread among the multiple threads finishes downloading, the thread starts new mail content to download, and the multiple threads simultaneously operate until all mail content is downloaded.

For example, the number of threads in the thread pool is 6, each thread separately starts downloading the mail content, for example, thread 1 is responsible for downloading the mail 1 content, thread 2 is responsible for downloading the mail 2 content, and in the case of abundant data transmission bandwidth, the downloading speed is 6 times that in the prior art.

By the method for starting the multithread downloading, a plurality of threads are started to independently download the mails of multiple packages, the defect of one package-to-one package downloading at present is overcome, and the speed of downloading the mails can be further improved under the condition of abundant data transmission bandwidth.

Furthermore, the embodiment provides a method for facilitating the user to preferentially download a specific mail, for example, when the mail content is downloaded in sequence after the mail header information has been downloaded, and the user is in a position to view a piece of mail content that has not been downloaded according to the downloaded mail header information, the method may be as follows:

And for the mails which are not downloaded, when the download instruction of the set mail is determined to be received, responding to a specified mail download instruction, and starting independent threads except the thread pool to download the set mail.

As an optional implementation manner, for a mail whose mail header information is downloaded and whose mail content has not been downloaded yet, determining, according to the mail header information, that a download instruction of the mail corresponding to the mail header information is received.

In this embodiment, the user may determine whether to download the mail starting independent thread according to the mail header information that has been downloaded, where the mail header information includes but is not limited to: mail title, sending user information, receiving user information, copying user information, secret sending user information and sending date.

On one hand, in the embodiment, a multithread simultaneous downloading starting mode can be adopted, and on the basis, an independent thread can be set and used for starting the independent thread to download the specified mail when a downloading instruction of the set mail is received, for example, when the downloading instruction of the specified mail by a user is received, so that the user can immediately check the mail content without waiting.

For example, there are 6 threads in the current thread pool that are respectively executing the downloading of the contents of the mails 1 to 6, but at this time, the user specifies to download the content of the 8 th mail, and when the user clicks the mail 8, the mailbox client will start an independent thread to download the mail 8 independently, which is not affected by the downloading progress of the 6 threads in the current thread pool.

At present, the downloading of the mail content generally adopts a serial downloading mode, namely, the downloading of the next piece of content is started after the downloading of one piece of mail is finished, the speed is low, the efficiency is low, and particularly when the content of a single piece of mail is large, the downloading time is long, and the user experience is poor. The embodiment adopts the thread pool scheme, and greatly improves the efficiency of mail downloading by simultaneously starting downloading by using a plurality of mails.

As shown in fig. 6, the implementation manner of the thread pool in this embodiment is described in detail as follows:

step 600, sorting all mails of which the mail header information is downloaded in the mail list according to the sequence of time;

specifically, the mails in the mail list have corresponding identification IDs and download statuses in the database, including but not limited to: the downloaded mail header information, the downloaded all mail content, etc.

601, creating a thread pool with the maximum thread number of N, putting all mails with downloaded mail header information into the thread pool, and preferentially downloading the latest N mails according to the time sequence;

and N is a positive integer and can be adjusted according to the performance of a terminal system, wherein if the performance of the terminal is higher, the created N is larger, and if the performance of the terminal is lower, the created N is smaller.

Step 602, adding other mails of the thread pool except the N mails into a blocking queue for waiting to be downloaded;

the blocking queue adopts a list blocking queue mode according to time sequencing, so that all mails of which the mail header information is downloaded can be ensured to be sequentially started to download the idle thread pool.

And 603, when the thread pool automatically judges that an idle thread exists, selecting a task from the blocking queue and downloading the task through the idle thread.

In the downloading thread of each mail, if the downloading state of the current mail is 'the content of the downloaded mail', the current thread is finished, and the current thread is in an idle state at the moment.

The downloading of all the undelivered mails can be completed circularly through the steps.

The method can be used for preferentially downloading the mail by adopting a mode of starting an independent thread when the mail which a user wants to view preferentially is not downloaded in the thread pool.

Example 2

As shown in fig. 7, a detailed flow of mail downloading is described in this embodiment, a mail downloading process in this embodiment is based on an IMAP protocol, and time-consuming operations of different links in the IMAP protocol are improved, and a flow of mail downloading specifically is as follows:

step 700, responding to the mail updating instruction;
