Embodiment
Fig. 1 is the flow chart of a kind of file synchronisation method among the present invention, as shown in Figure 1,
Step 101 is set up client and is connected with network between the server end, and the monitoring folder path is set.
Step 102 if the file in the described monitoring file changes, is put into file RTP message with the file that changes, and sends to server end.
Step 103 by resolving described file RTP message, is obtained the file and the operational order of destination server information, described change.
Step 104 is carried out corresponding operating according to described operational order at destination server, replys operation after operation is finished and finishes prompting message.
In order to make the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
The technical scheme that provides among the present invention is applicable to, can not directly be communicated with between local network and the destination server network, local file is synchronized to be needed in the destination server to operate by the redirect machine, wherein, in a kind of file synchronisation method provided by the invention, in this locality client is installed, in the redirect machine, server end is installed.
Fig. 2 is the detail flowchart of a kind of file synchronisation method among the present invention, as shown in Figure 2,
Step 201 starts client, and the path of monitoring file is set; In this step, start policer operation to the monitoring file after, set up a Socket between client and the server end and be connected.
Step 202, client is monitored the monitoring file, file changes in the file if monitor, then the triggering synchronous flow process.Wherein, file changes and comprises in the described monitoring file: file increases, file deletion and file modification.
Step 203, client is put into the main part of file RTP message with the file that changes, and adds a plurality of message headers in described file RTP message; Described file RTP message of having added message header is sent to server end.Wherein, if the file in the described monitoring file increases, the file of described increase is put into file RTP message; If the file modification in the described monitoring file is put into file RTP message with the file of described modification; If the file in described monitoring file deletion is put into file RTP message with the filename of the file of described deletion.
In this step, carry an essential information in the message header, the information of carrying in the message header that is added has: be used to deposit storing directory, the operating system of destination server, the type of destination server and the operational order of carrying out corresponding operating that changes file in the network address of destination server, the destination server; In other embodiments of the invention, can carry out function to described message header according to the actual requirements expands.
Step 204, server end receives the file RTP message from client, and described file RTP message is resolved, and parses the file of information, operational order and the described change of described destination server; The information of described destination server comprises: be used to deposit the storing directory that changes file, the operating system of destination server, the type of destination server in the network address of destination server, the destination server.
The network address of the destination server that server end obtains according to parsing, set up with destination server between network be connected, the OS Type of the destination server that obtains according to parsing adopts dos command, SSH safety shell protocol or SFTP Secure File Transfer Protocol to carry out corresponding operating.Wherein, if the window system adopts dos command to operate, if linux system adopts modes such as SSH or SFTP to operate.
Server end is operated accordingly according to the operational order that parsing obtains: if described operational order increases described file for increasing in the storing directory in destination server; If described operational order is for revising, in the storing directory in destination server original replaced to described file; If described operational order is deleted original in the storing directory in destination server for deletion.
Step 205, server end judge whether the operation on destination server is successful, if operate successfully, then carry out step 206; If operation is unsuccessful, then carry out step 204.
Step 206, server end send to client with the information of complete operation by file RTP message after being operable to merit on the destination server; After client was resolved the described file RTP message that receives, the operation of affirmation file synchronization was finished.
In a preferred embodiment of the present invention, a kind of form of file RTP message is provided, as shown in table 1.
| First byte |
| Message header [numbering of message header, the length of message header, the value of message header] |
| Message header [numbering of message header, the length of message header, the value of message header] |
| Message header [numbering of message header, the length of message header, the value of message header] |
| ....... |
