The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although showing the disclosure in accompanying drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here Limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure Complete conveys to those skilled in the art.
In order to solve the above technical problems, the embodiments of the invention provide a kind of method for obtaining file, it is adaptable at file Manage server.Fig. 1 shows the schematic flow sheet of the method for acquisition file according to an embodiment of the invention., should referring to Fig. 1 Method at least includes step S102 to step S110.
Step S102, receives the file acquisition from client forwarded by web cluster and asks.
In the step, the form of file acquisition request can be HTTP (HTTP, Hyper Text Transfer Protocol), Hyper text transfer security protocol (HTTPS, Hyper Text Transfer Protocol over Secure Socket Layer) and FTP (FTP, File Transfer Protocol) etc., the present invention is implemented The concrete form that example is asked file acquisition is not limited.
In the step, multiple web servers can be included in web cluster, such as Nginx servers, Internet take Business device etc., embodiment of the present invention onserver-class is not specifically limited.
Step S104, it is determined that when the local file acquisition that is not stored with asks asked file content, waiting and coming from file Monitoring server, carry and notified because system file changes the monitoring of new file content generated.
In this step, file monitor server can be with the change of monitoring system file, while can also receive after change New file content.When file monitor server monitoring to system file changes, the server generation of triggering file generated is new File content, and the new file content that is generated from file generated server is received, while new file content is taken Band is sent to document processing server in monitoring is notified.
Step S106, when receiving monitoring notice, reads the new file content carried during monitoring is notified, judges newly Whether end mark that file terminated is included in file content.
In the step, the end mark that file has terminated actually is intended to indicate that file acquisition asks asked file The identifier whether content has generated completely.End mark can be a numeral, letter or character string etc. Deng.If including end mark in new file content, then it represents that file acquisition asks asked file content to be given birth to completely Into if not comprising end mark in the new file content, then it represents that file acquisition asks asked file content not Have and generated completely, be only to generate a part of file content, and now file acquisition is asked at asked file content In dynamically growth state.
End mark in the step can be added new by file generated server after new file content is generated File content in or by file monitor server receiving file generated server transmission new file content It is added to afterwards in new file content, the embodiment of the present invention is not limited this.
Step S108, if comprising end mark, deleting end mark, and the file content after deletion is sent to web collection Group, so that the file content after deleting is forwarded to client by web cluster.
Step S110, if not comprising end mark, new file content being forwarded into web cluster, makes new file content Client is forwarded to by web cluster, and continues to the monitoring for carrying new file content from file monitor server Notify, until including end mark in new file content.
In the embodiment of the present invention, when the file from client that document processing server receives web cluster forwarding is obtained Request is taken, and when determining that the local file acquisition that is not stored with asks asked file content, document processing server can be selected Select wait it is from file monitor server, carry and lead to because system file changes the monitoring of new file content generated Know.If the monitoring that document processing server receives the transmission of file monitor server is notified, and by judging to learn that monitoring is notified End mark is included in the new file content of middle carrying, then it represents that new file increases and terminated, document processing server can be with The file content deleted after end mark is sent to web cluster, user is then transmitted to by web cluster.If in new file Do not include end mark in appearance, represent that new file increases, i.e., the demand file content that user is asked is in dynamic and increased Long status, document processing server also needs the monitoring for continuing waiting for file monitor server to notify until being wrapped in new file content Contain end mark.Thus, no matter the file content that user is asked, whether in dynamic growth state, passes through the present invention program User can be made to get the file content of request in time.Particularly, if by judging to learn in new file content do not have When having comprising end mark, i.e., when the demand file content that user is asked is in dynamic growth state, document processing server The monitoring for pending file monitoring server always is notified, to receive the new file content of generation in time until new file End-of-file mark is included in content, when including end-of-file mark in new file content, the file of this request of user Content obtaining is completed.In the process, request is just got after waiting demand file content to be all generated without user File content, so as to effectively improve the real-time for obtaining file, reduce user and wait in asked demand file Hold the time of generation, and then improve the operating experience of user.
Step S102 is seen above, in an embodiment of the present invention, web cluster, can when receiving the request of client So that the web server for receiving file acquisition request is selected in web cluster according to load-balancing algorithm.Wherein, load equal Weighing apparatus refers to entering the loading condition of the website of each in system (such as server) Mobile state adjustment, to eliminate or reduce system as far as possible In each website load imbalance phenomenon.Concrete methods of realizing can be that the task on heavily loaded website is transferred into other underloadings On website, the load balancing of each website in system is realized as far as possible, so as to improve the handling capacity of system.In the embodiment, File acquisition can be asked on the relatively low server of the load being assigned in web cluster, with by loading relatively low server Manage this document and obtain request task.
Step S104 is seen above, in an embodiment of the present invention, if document processing server determines that text has been locally stored Part obtains the asked file content of request, then, the file content of request can be directly read and sent to web cluster, with The file content of request is set to be forwarded to client by web cluster.By file acquisition ask asked file content send to During web cluster, the file content of request can be packaged into the form of chunk with first, so by the file content of request with The form of chunk bags is sent to web cluster.
With continued reference to above step S104, in an embodiment of the present invention, when file monitor server monitoring to system text When part changes, such as system file is created, deletes or changed, and can be created, repaiied by file generated server foundation Change or the system file deleted generates new file content, so that by file monitor server by the new file content of generation Carry in monitoring is notified and send to document processing server.
In this embodiment, document processing server wait from file monitor server, carry because system text , can also be by judging to wait from file monitor server when the monitoring for the new file content that part change is generated is notified Monitor whether the stand-by period notified exceedes preset time, to determine whether document processing server needs to continue waiting for monitoring logical Know.For example, preset time can be 3 seconds, 4 seconds, the time such as 5 seconds, the embodiment of the present invention is not specifically limited to preset time.
If the stand-by period of the notice to be monitored such as document processing server is logical receiving monitoring not less than preset time When knowing, the new file content carried during monitoring is notified is read, and determine whether whether include file in new file content The end mark terminated.
If the stand-by period of the notice to be monitored such as document processing server exceedes preset time, it is determined that this file acquisition Request failure, and from document processing server to web cluster send file acquisition request failure notification message, and then again by Web cluster will ask the notification message of failure to be forwarded to client.The request failure notification message can be voice, word, The forms such as numeral.Such as, the notification message " file acquisition fails, and file is please obtained again " of written form.
Referring to step S106, in an embodiment of the present invention, when document processing server is reading carrying during monitoring is notified New file content when, file monitor server monitoring to client send to web cluster file acquisition request be disconnected, Such as, any one device fails, network disconnect in client and web cluster, or user closes client, refreshes client Page of display etc. is held, the connection that these situations can all cause the file acquisition between client and web cluster to be asked disconnects.This When, file monitor server can trigger the reading that document processing server interrupts new file content, and by file process service Device sends interrupt notification message to web cluster, and then interrupt notification message is forwarded to client by web cluster, so that user Solve file acquisition failure.
In order to clearly embody the embodiment of the present invention, now the present invention is carried out with the embodiment under a concrete scene Introduce.In this embodiment, client is " 360 secure browser ", and it is video that file acquisition, which asks asked file content, Content.
When user opens " 360 secure browser ", and click on the video " beginning lecturing " on " 360 secure browser " page, " 360 secure browser " can send http agreement requests to corresponding web cluster.When web cluster receives http agreement requests When, the relatively low web server of a present load can be chosen and receive http agreement requests, when the web server of selection is received To after http agreement requests, the http agreement requests are forwarded to document processing server.
When document processing server receives the http agreement requests of video file " beginning lecturing ", first determine it is local in whether Be stored with the video file content of " beginning lecturing ", if so, then directly send the video file of " beginning lecturing " to web server, Web server, can be by after transcoding after carrying out transcoding according to the order of video time line to video file " beginning lecturing " and caching Video file send to " 360 secure browser " so that on " 360 secure browser " play video " beginning lecturing ".
If it is determined that be not stored with document processing server " beginning lecturing " video file content when, document processing server It can select to wait the monitoring from file monitor server to notify.When video file of the file monitor server monitoring into system When " beginning lecturing " is created, file generated server generation video file " beginning lecturing " can be triggered.File generated server is in life Into after the partial content of video file " beginning lecturing ", first the partial video file content of generation can be sent to file monitor and taken Business device, and then sent partial video file content carrying to file process clothes in monitoring is notified by file monitor server Business device.Document processing server is received after monitoring notice, is read out partial video file content in being notified from monitoring and " is begun lecturing ".
If document processing server is learnt by judging, not comprising end in the partial video file content " beginning lecturing " Mark, then be forwarded directly to web server, and continue waiting for monitoring notice by the partial video file content " beginning lecturing ".So Afterwards, web server carries out transcoding simultaneously to the partial video file content " beginning lecturing " received according to the order of video time line Sent after caching to " 360 secure browser ".And then, " 360 secure browser " " is opened the partial video file content received Say " played out according to the order of transcoding.
If document processing server is learnt by judging, end mark is included in the partial video file content " beginning lecturing " Will, then delete the end mark, and the partial video file content " beginning lecturing " is sent to web server.Web server pair The partial video file content " beginning lecturing " received according to video time line order carry out transcoding and cache after send to " 360 secure browser ".And then, " 360 secure browser " is to the partial video file content " beginning lecturing " that receives according to turning The order of code is played out.
Certainly, above-described embodiment is only schematical, and file acquisition asks asked file content not merely to limit In video file, other any file contents are can also be, e.g., text content, audio file content etc., the present invention are implemented Example is not limited the type of file.But, the process of file acquisition is roughly the same, and the embodiment of the present invention is not another to this One introduces.
