Abstract
The invention provides a method for transmitting documents by breakpoint transmission with an instant communications tool, which includes the following steps: when a client terminal receives documents, a server is connected, an instruction for receiving documents is sent to the server, and the client terminal then creates a new task of document transmission; after the instruction for receiving documents is received by the server, the data of the documents are sent to the client terminal which stores the data of the task on a regular basis; if the client terminal fails to complete the receiving of the documents, the client terminal then transmits the task information to the server requesting for receiving the remaining document data, the server then continues to transmit the remaining document data after receiving the request when a user receives documents the next time; if the client terminal completes the receiving of the documents, the client terminal then notifies the user that the receiving is completed, and the task of document transmission is deleted. The time for repeated transmission is saved in transmitting documents by breakpoint transmission, and the pressure on network is alleviated, thus improving efficiency of transmission and strengthening the ability to withstand risks. Therefore, the method is suitable for the instant communications software applied in ever-changing network environment with frequent on-and-off-line of users.
Description
Technical field:
The present invention relates to computer software, network communication field, instant messaging especially particularly relates to and a kind ofly uses breakpoint transmission to carry out the method for file transfer in JICQ.
Background technology:
Instant messaging (Instant messaging is called for short IM) has become the important means that the user communicates by network, and a lot of JICQs are arranged at present, QQ as company of Tengxun, the MSN of Microsoft also has some enterprise immediate communications, as RTX, Sametime etc.
The instant messaging product is used by increasing people, file transfer then is very important in an instant messaging function, present immediate communication tool, during transfer files, if interrupt, the transmission primaries again that then can only start anew can't continue the remaining file data of transmission in last time on the uncompleted basis.As: when the user receives the file of a 10M, when receiving 9M, because network interrupts, after client was logined again, when the user received file once more, the file of this 10M needed to restart transmission again.
Summary of the invention:
The present invention provides a kind of and has used breakpoint transmission to carry out the method for file transfer in JICQ for addressing the above problem weak point.
In order to address the above problem, the invention provides following technical scheme: a kind of method of using breakpoint transmission to carry out file transfer in JICQ comprises the steps:
When a. client received, the Connection Service device sent the file command that receives to server, client new files transformation task;
B. after server is received file command, send file data to client, client scheduled store task data;
If c. client is not finished reception, when then next user continued to receive, client sent to server to mission bit stream, and request receives remaining file data, after server is received, continued to send remaining file data;
If d. client is finished reception, then client notifies the user to finish reception, and the deleted file transformation task.
Described step also comprises
2.1 server finishes receiving the file data that the sender sends;
2.2 the server notification client has the fileinfo of not accepting.
The fileinfo to be received that described file command comprises is that server sends to client by notification message.
Described task data comprises file unique identification, sender, transmitting time, recipient, filename, file size, file modification time, file verification value, the byte number that has received, last time of reception.
Described file unique identification is that server generates and sends to client.
Advantage of the present invention:
When the user uses the instant communication client transmission or receives file, client and server can be preserved transmission progress, if imperfect tense end in transmission, no matter be that accidental interruption or user suspend, then the user can continue the remaining file data of transmission next time on original basis.Transfer files uses breakpoint transmission to save the time that repeats to transmit, and has alleviated the pressure of network, thereby has improved the efficient of transmission, and the ability to ward off risks is strong simultaneously, is well suited in the software big in this change of network environment of instant messaging, that user's going on line or off line is frequent.
For example the user receives the file of a 10M, and when receiving 9M, network interrupts, if every biographys 1M needs 20 seconds, does not support the time that breakpoint transmission needs: 200 seconds of the 180 seconds+transmission afterwards that begins to transmit.Under the situation that repeatedly transmission is interrupted, the transmission time that needs is longer.And the time of utilizing this method to realize that breakpoint transmission needs is about 200 seconds, no matter interrupt several times.
Description of drawings:
Fig. 1 receives document flowchart for client of the present invention.
Embodiment:
As shown in Figure 1, a kind of method of using breakpoint transmission to carry out file transfer in JICQ comprises the steps,
S1. server finishes receiving the file data that the sender sends.Server is finished and is received the back storage file, prepares beginning then and transmits to recipient's client.
S2. the server notification client has the fileinfo of not accepting.
When S3. client receives, the Connection Service device, the file command that sends reception is to server, and the fileinfo to be received that this document order comprises is that server sends to client by notification message, client new files transformation task.
S4. after server is received file command, send file data to client, client in the process that receives file, scheduled store file task data, as: 5 seconds are once;
The content of task data comprises:
File unique identification, sender, transmitting time, recipient, filename, file size, file modification time, file verification value, the byte number that has received, last time of reception.
Wherein the file unique identification is that server generates and sends to client, the file of unique identification transmission.
The file verification value is that file content is carried out the value of digest calculations by the technology of MD5 or SHA1 and so on, and in theory, as long as file content changes, then the value of Ji Suaning will change, so client is used for the file that receives is carried out verification.
The byte number that has received is the byte number that client storage has received, and guarantees that the byte of transmission is not accurately transmitted.
Original position when the byte number that has received is used for writing down next client and continues to receive.Suppose that this document is 100 bytes, if client interrupt when receiving 80 bytes, when then next client receives since the 81st byte.
If S5. client is not finished reception, when then next user continued to receive, client sent to server to mission bit stream, and request receives remaining file data, and server receives that follow-up supervention send remaining number of files.
If S6. client is finished reception, then client notifies the user to finish reception, and the deleted file transformation task.
