Embodiment
When user's login does not provide the Website server of E-mail service; In order to make this user receive the Email that other mail servers (being the POP3 server) send through said Website server; In the embodiment of the invention; User's Website login server, and be sent to acting server through the request message that this Website server will be used to receive mail, carry the mailbox sign of at least one E-mail address of user binding in this request message; Said acting server is downloaded mail according to the mailbox that carries in described request message sign from corresponding POP3 server, and the e-mail messages after will upgrading through said Website server is tabulated and sent to said user; Said acting server sends to this user with the mail of appointment through said Website server according to user's selection.
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
Consult shown in Figure 1ly, the communication system in the present embodiment comprises Website server 10, acting server 11, caching server 12, storage device 13 and POP3 server 14.
Said Website server 10 is used for to the user website service being provided; And when the user need receive mail; The request message that the user is sent is sent to acting server 11; And the tabulation to said user's e-mail messages that acting server 11 issues sent to this user, and behind the mail of selecting to need to download said user, the corresponding mail that acting server 11 is returned is transmitted to this user.
Said acting server 11 is used to receive the request message in order to the reception mail that Website server 10 sends, and carries the mailbox sign of the E-mail address of the user binding of logining this Website server 10 in this request message; Acting server 11 is downloaded mail according to the mailbox sign of carrying in the request message that receives from corresponding POP3 server 14, and the e-mail messages tabulation to said user that preserve this locality is upgraded; The tabulation of e-mail messages after acting server 11 will upgrade sends to Website server 10, and according to user's selection the mail of user's appointment is sent to Website server 10.
Said caching server 12 is used for when acting server 11 is handled the request message that receives, preserving the log-on message of the E-mail address that this request message carries.
Said storage device 13 is used to preserve the mail that acting server 11 is downloaded from POP3 server 14.
Said POP3 server 14 is used to store user's mail data, and according to the operational order of acting server 11 corresponding mail is sent to acting server 11.
In practical application; The function of acting server 11, caching server 12 and storage device 13 can be integrated in the same functional entity; Perhaps; Acting server 11 also can be used as a functional module in other communicators and exists, and the multiple systems framework all can be realized same invention effect, and the embodiment of the invention provides relative preferred implementation.
Consult shown in Figure 1B, said acting server 11 comprises memory cell 110, receiving element 111, processing unit 112 and transmitting element 113.
Said memory cell 110 is used to store user's e-mail messages tabulation;
Said receiving element 111 is used to receive the mail that Website server 10 sends downloads from POP3 server 14 in order to the request message that receives mail and this acting server 11;
The mailbox sign that said processing unit 112 is used for carrying according to request message is downloaded mail from corresponding POP3 server 14, and said user's e-mail messages tabulation is upgraded;
Said transmitting element is used for the e-mail messages tabulation after upgrading and the mail of user's appointment are sent to Website server 10.
In the embodiment of the invention; The quantity of acting server 11 can be one or more; If there are a plurality of acting servers 11 (being server proxy cluster); Then in server proxy cluster, adopt hardware or software to realize load balancing, the request message that Website server 10 sends evenly is distributed to each server in the cluster.
For the mass memory of realizing data and the fail safe that guarantees customer data; Optimum execution mode is to adopt the memory device of specialty to preserve mail data; But the dedicated storage equipment expensive price can increase the cost of building the mail agent system if the storage device in the mail agent system 13 all is set to high performance dedicated storage equipment.Therefore; The big and access speed requirement height according to mail data mail data near-mid term visit possibility; And the historical mail data visit characteristics that possibility is less and access speed is relatively low; Present embodiment is separately preserved mail data according to the time of reception of mail data, because the restriction of file system, the file under the same catalogue/catalogue number is too much unsuitable; Thereby the algorithm that adopts " time+month+date+N level catalogue+random file name at random " obtains the path of depositing of mail data; Wherein, each level directory name at random includes only two ASCII (asci) letter/number, is no more than 36*36=1296 to guarantee the subdirectory number under every grade of catalogue; Simultaneously; In order to guarantee the access speed of recent mail data; Recent mail (like the mail data in a nearly week) is deposited on the high performance dedicated storage equipment, and historical mail data is deposited on the slower memory device (like read-only device) of cheapness, access speed.
Based on the said system framework; In the present embodiment; Website server 10 is the server of website A; And Website server 10 does not provide the E-mail address service, the mail server that POP3 server 14 is belonged to for user's E-mail address (mailbox 1), and this user is bundled in the information of mailbox 1 in the log-on message of self when website A registers; The user can also bind the information (like mailbox 2, mailbox 3, mailbox 4......) of other a plurality of E-mail addresses simultaneously in said log-on message, present embodiment is that example describes with mailbox 1 only.
Consult shown in Figure 2ly, acting server 11 is following from the detailed process that POP3 server 14 receives mails:
Step 200: behind user's Website login A, send the request message (being called message 1) that is used for receiving mail to acting server 11, comprise the mailbox sign (being called sign 1) of mailbox 1 in the message 1 from mailbox 1 through Website server 10.
Step 210: acting server 11 is checked the operating position of thread, and is judged in the current thread of having set up whether have the thread that is in idle condition, if then carry out step 220 after receiving the message 1 of Website server 10 transmissions in the thread pool of this locality; Otherwise, carry out step 230.
In practical application, acting server 11 is when the more request message of concurrent processing, and the thread that can create respective numbers according to actual needs is with complete operation; Simultaneously, acting server 11 can be cancelled idle thread for a long time when relatively more idle, with free system resources, reduction system load.The establishment of thread and cancel all and need consume certain system resource, so acting server 11 will reuse the thread of having set up as far as possible when the request message that processing receives, rather than all create new thread at every turn.The thread of 11 pairs of this locality of acting server is managed for ease, has introduced the notion of " thread pool " in the present embodiment, and said thread pool is used for the quantity of control agent server 11 active threads, and the relevant parameter of its setting is following:
< a>minimum Thread Count: the minimum number of threads that acting server 11 need be kept, even all being in idle condition, these threads can not they be cancelled;
<b>maximum thread: maximum number of threads that acting server 11 can parallel processing.
< c>thread the longest standby time: the quantity of the thread of in acting on behalf of server 11, having set up allows unnecessary thread to be in the maximum duration of idle condition during greater than " minimum Thread Count "; If the time that a certain thread is in idle condition in the said unnecessary thread surpasses preset threshold, then acting server 11 is cancelled this thread.
Step 220: acting server 11 distributes a thread from the current thread that is in idle condition, in order to processing messages 1, then carry out step 260.
Step 230: whether the quantity of the thread that acting server 11 further judgements have been set up surpasses maximum thread, if then carry out step 240; Otherwise, carry out step 250.
Step 240: acting server 11 adds waiting list with message 1, through this thread message 1 is handled when waiting some threads to get into idle condition again, then carry out step 260.
Step 250: acting server 11 is created a new thread in thread pool, through this thread message 1 is handled, and then carry out step 260.
Step 260: acting server 11 further judges whether response message 1 according to the relative recording of caching server 12, if then carry out step 270; Otherwise, finish current flow process.
In practical application; Website server 10 is sometimes because the former thereby continuous of user's operation sent identical request message to acting server 11; To this situation; Present embodiment has adopted following method to solve: owing to carry the mailbox sign of user's electronic mailbox in the request message; Therefore, acting server 11 is when processes said request message, and the mailbox sign that in caching server 12, comprise according to this request message is registered to represent that the mail data in this E-mail address is processed corresponding E-mail address; After executing the processing operation, acting server 11 also will write down the last processing time and nullify this E-mail address in caching server 12; If carried the mailbox sign of a plurality of E-mail addresses in the request message, then a plurality of mailbox signs in 11 pairs of request messages of acting server are carried out parallel processing.
According to said method, in the present embodiment, acting server 11 successively judges whether the message 1 that receives is responded through following two kinds of methods.
First method: acting server 11 judges according to the sign that comprises in the message 11 whether mailbox 1 is registered in caching server 12, if then finish current flow process; Otherwise, continue to judge through second method.
Second method: acting server 11 obtains the time of mail data in the last processing mailbox 1 according to the sign that comprises in the message 11; And whether the interval of further judging this time and current time is less than setting threshold; If then acting server 11 thinks that the number of times that Website server 10 sends message 1 too frequently and automatically finishes current flow process; Otherwise, acting server 11 response messages 1.
Step 270: acting server 11 is registered mailbox 1 in caching server 12, and sends the unique tabulation of mail identifier (Unique ID Listing, UIDL) order to POP3 server 14.
If carried the mailbox sign of a plurality of E-mail addresses in the request message that Website server 10 sends; Then acting server 11 is registered a plurality of mailbox signs in the request message in caching server 12 simultaneously, and sends the UIDL order to its corresponding POP3 server respectively.
Step 280:POP3 server 14 returns the ID tabulation of all mails in the current mailbox 1 to acting server 11, and the mail of preserving in mail ID tabulation that acting server 11 is preserved this locality according to the mail ID tabulation that receives and the storage device 13 carries out corresponding renewal.
In the present embodiment; The ID tabulation (being called tabulation C) of the mail of once downloading from mailbox 1 before preserving on the acting server 11; When acting on behalf of ID tabulation that server 11 receives all mails in the current mailbox 1 that POP3 server 14 returns when (being called tabulation S), the S that will tabulate makes otherness with tabulation C and compares:
1) if the ID of certain mail is recorded among the tabulation S; And be not recorded among the tabulation C; Then acting server 11 belongs to the ID of this mail to " new mail set "; From the mailbox 1 of POP3 server 14, download corresponding mail according to the mail ID that is somebody's turn to do in " new mail set " simultaneously, and newly downloaded mail is saved to the relevant position of storage device 13.
2) if the ID of certain mail both had been recorded among the tabulation S, be recorded in again among the tabulation C, then acting server 11 belongs to the ID of this mail to " keeping the mail set ".
3) if the ID of certain mail is recorded among the tabulation C, and be not recorded among the tabulation S, then acting server 11 belongs to the ID of this mail to " waiting to delete the mail set ".
After tabulation S was divided into three types with the mail of tabulation among the C, acting server 11 was carried out different operation according to the quantity of the mail ID in " waiting to delete the mail set ":
If the quantity of mail ID does not reach preset threshold in " waiting to delete the mail set ", then acting server 11 keeps existing tabulation C, simultaneously the mail ID in " new mail set " is recorded among the tabulation C, and this mode is called " append mode ".
If the quantity of mail ID has reached preset threshold in " waiting to delete the mail set "; Then acting server 11 is C.bak with existing tabulation C backup; Create a new tabulation C simultaneously, and " new mail set " and the mail ID in " keeping the mail set " are recorded among the said new tabulation C, then; Backup file C.bak before the deletion, this mode is called " reconstruction mode ".If the process of carrying out " reconstruction mode " is because of the accident aborted; Information among the tabulation C of so said new establishment is unreliable; Acting server 11 will be deleted the tabulation C of this new establishment this moment; Recover former tabulation C according to backup file C.bak simultaneously, and the mail ID in " new mail set " is added among the said former tabulation C.
Step 290: the information among the tabulation C that acting server 11 will newly be created through Website server 10 is presented to the user, and according to user's operation corresponding mail is sent to the user through Website server 10.
In the above-described embodiments; Website server 10 adopts asynchronous system to send a request message to acting server 11, and promptly Website server 10 only adds it in formation after generating request message, and this request message of wait acknowledge is not sent out; Can not wait for the result that receives this request message yet; Check queue element (QE) by background work thread poll, with the information interaction of completion, like this with mail proxy server 11; The availability of acting server 11 and treatment effeciency just can not have influence on the response speed of Website server 10, thereby have guaranteed user's experience to a certain extent.
In sum; In the embodiment of the invention; The user can directly not receive mail from one or more POP3 servers through this Website server 10 when login does not provide the Website server 10 of E-mail address service; So just, reduce user's operation complexity, improved user experience to a certain extent; Simultaneously; Acting server 11 has played cushioning effect between Website server 10 and corresponding POP3 server; When the huge request message of Website server 10 concurrent quantity; Acting server 11 has slowed down the visit pressure that a large amount of concurrent requests causes for the POP3 server, thereby has improved the stability of system to a certain extent.
On the other hand, in the embodiment of the invention, acting server 11 can so just guarantee the response speed of system to Website server 10 according to system resources such as the load reasonable distribution thread of system, internal memories; Simultaneously, acting server 11 had so both guaranteed the access speed of recent mail data according to the distributed mail data of depositing of the download date of mail, had reduced the cost that on storage device 13, drops into again.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technologies thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
