Abstract
The invention provides a method for analyzing and downloading a network file address of a thin client. The method is used for analyzing whether a remote file address inputted by a user is valid or not, returning file information and downloading a file to a downloading storage space of a network file of a user. By the method, the network address is simply and reliably analyzed, the method can inform the user of true information of the network address before downloading, so that a wrong file, a web page link and a wrong web page cannot be downloaded, high-intensity work of a server cannot be affected by an overlarge downloaded file, a remote file is directly downloaded to a network disk of the user by the method, the method is more efficient as compared with a method for firstly downloading the remote file to a local disk and then uploading the remote file to the server, the server still can automatically download the file after the user logs off, and waiting time of the user is shortened.
Description
Technical field
The present invention relates to a kind of network file address resolution and method for down loading for thin-client, belongs to the network storage
Technical field.
Background technology
In recent years, with computer network, the development of thin client terminal, meeting user's request, improving user's requisite number
According to safety, reduces cost, be easy to dispose and safeguard etc. and require under, based on " thin-client+network+cloud computing server "
Pattern is into certainty.In such a mode, user to the verity of required telefile address, the transporting of telefile, under
It is loaded onto high efficiency of user's storage server etc. and proposes preferably requirement.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of network file address resolution for thin-client and under
Support method.The method is whether the telefile address of parsing user input is effective, returns fileinfo and is downloaded to user network
The method of network file download memory space.
Technical scheme is as follows：
Under a kind of network file address resolution and method for down loading for thin-client, including parsing remote address and file
Load program, it is specific as follows：
The step of parsing remote address, return address information approach such as 1）-8）：
1）Dropbox is logged in, the fileinfo that login user has been stored is read；
2）Network file download button is clicked on, the network address of user input network file is pointed out；
3）Behind the network address of Web server receiving user's input, and array ARRAY is obtained, the array includes clothes
Business device responds all headers that a HTTP request is sent；
4）Server judges whether http response is successful, if success, i.e. ARRAY [0] is 200 or 302 or 302Moved
Temporarily, performs next step；Otherwise, user's this address is pointed out not to be that effective address, i.e. a this address cannot be beaten
Open, skip to step 8）；
5）Obtain file type ARRAY [Content-Type] and network address points to address ARRAY [Location] or ARRAY
[location], if there is character string " application " in file type or point to address existed, then it represents that this address
Middle presence can download file, and this points to address and is the file source address that user needs, execution step 7）；Otherwise, perform next
Step；
6）File type is judged with the presence or absence of character string " text/html ", and without address is pointed to, if it is not, informing user
The file of input is unknown；If so, the address for informing user input is not download address, it may be possible to a web page interlinkage, and is pointed out
This link whether is downloaded, if downloading, next step is performed, otherwise, is skipped to step 8）；
7）Obtain file size, if file be less than enactment document size, the enactment document size with ensure service
Device normal work, e.g., less than 20M, return source address, and startup file downloads；Otherwise point out file larger, using download
Instrument is downloaded；
8）Parsing terminates；
The step of file download program such as step 9）-14）：
9）Start；
10）The file of source address is opened in read-only method；
11）In user network file download memory block new files, filename is the filename obtained from source address；
12）The content for pointing to address file is read, and writes newly-built file, terminated until source file reads；
13）Judge whether the filename downloaded is url codings, if so, by filename RNTO source original document name；If
It is no, perform next step；
14）Terminate.
According to selected by the present invention, client of the thin-client for built-in Linux operating environment, there is provided input,
Outut device, is embedded in web browser.
According to currently preferred, the server end is cloud computing server cluster, is built by multiple servers,
Provide the user correspondence memory block and web-based management service.
Advantage of the invention is that：
（1）It is simple and reliability is high using the present invention parsing network address；
（2）Method of the present invention may inform the user that the real information of this network address before downloading, prevent down
Wrong file, downloads web link are carried, wrong webpage is downloaded, is downloaded excessive impact server intensive work of file etc.；
（3）Telefile is directly downloaded to user's Dropbox by method of the present invention, is first downloaded to locally again than user
Upload onto the server more efficient；
（4）After user logs off, server still can download file to the present invention automatically, reduce the waiting time of user.
Description of the drawings
The step of what Fig. 1 was represented is the server parsing network address of the present invention is schemed, wherein,
1. user input url；
2. server responds the request of a http；
3. whether response is successful；
4. there is application or there is sensing address in file type；
5. the source address of file is obtained；
6. obtain whether file size is less than 20M（It is variable）；
7. whether download；
8. start server to download；
9. there is text/html in file type；
10. this is a network linking；
The type of 11. files is unknown；
The address of 12. user inputs is unknown（Misprinted addresses）；
13. telefiles are excessive, it is proposed that download this document using downloader.
What Fig. 2 was represented is the address resolution interaction between web browser and server, wherein,
14. log according to account and password Dropbox；
Logging in for 15. response servers, obtains the information of this user storage space；
16. user files show；
17., to download telefile, point out the user input network address；
18. servers respond all headers of http request；
The 19. all information for obtaining address, parsing obtain the real source address of file；
20. return analysis result；
21. startups download, and download file to user network file storage according to parsing address；
After the completion of 22. download, terminate current download.
Specific embodiment
The present invention is described in detail with reference to example and Figure of description, but not limited to this.
