Embodiment
The flow chart of the data transmission method of the websocket agreement that Fig. 1 provides for the embodiment of the present invention, as shown in Figure 1, the method comprises:
Support the server of websocket in the access request that receives the client transmission of supporting websocket, and before returning to the needed original document of user according to access request to client, first server consults with client the compression type information of jointly supporting, negotiations process specifically comprises: user end to server sends the compression type information of self supporting, such as gzip, rar, zip, cab, 7z, tar etc., the compression type information that the compression type information that server is supported according to self and client send compares, choose the compression type information that identical compression type is supported jointly as both sides, and feed back to client.Then the compression type information that server is supported jointly from both sides, determine the first compression type with the type matching of the original document to client to be transmitted, concrete deterministic process is the corresponding relation that server this locality stores file type and compression type, this corresponding relation is based on those skilled in the art application compression algorithm corresponding from different compression types, dissimilar file to be carried out to compression efficiency test to obtain, thereby this corresponding relation of server lookup obtains the first compression type with the type matching of the original document to client to be transmitted.
After server is determined the first compression type with the type matching of the original document to client to be transmitted, apply the compression algorithm corresponding with the first compression type this original document is compressed to processing, it should be noted that, applied compression algorithm compresses to process to this original document and belongs to prior art, repeat no more herein, only take gzip compression algorithm as example simple declaration, the process of compressing html file such as application gzip compression algorithm is: find the repeat character string in input data, the character string that secondary occurs is replaced by a pointer that points to last character string, wherein, pointer is with right form--and distance and length represent, if distance is defined as 32KB, length is defined as 258 bytes, if the character string that secondary occurs does not occur in this front 32KB, it will send as word byte sequence.Further, in order to improve compression efficiency, server is before compressing processing to original document, whether the size that first judges this original document is more than or equal to default threshold value, if judgement knows that the size of this original document is more than or equal to this threshold value, the application compression algorithm corresponding with the first compression type compressed processing to original document, if judgement knows that the size of this original document is less than this threshold value, this original document is moved into buffer area, reach after default cache-time, the application compression algorithm corresponding with the first compression type compressed processing to depositing one or more original documents of buffer area in again.Server is after compressing original document and finishing dealing with, by the compressed file of application the first compression type sign by and client between TCPsocket passage send to client, client knows that this compressed file is that the server application compression algorithm corresponding with the first compression type compressed after applying the compressed file of the first compression type sign, therefore client is applied the compression algorithm corresponding with the first compression type and this compressed file is carried out to decompression is obtained original document, and original document is shown to user by client.
The data transmission method of the websocket agreement that the present embodiment provides, first support the server of websocket by consulting with supporting the client of websocket the compression type information of jointly supporting, then determine the first compression type with the type matching of original document waiting for transmission, apply the compression algorithm corresponding with the first compression type original document is compressed to processing, and by TCPsocket passage, the compressed file of application the first compression type sign is sent to client, the client application compression algorithm corresponding with the first compression type carried out decompression to compressed file and obtained original document, thereby improved client and server refer between data transmission efficiency based on websocket agreement.
Based on above-described embodiment, further, described method also comprises: when client need to be applied the second compression type and decompresses, can initiatively to server, send the change request that comprises the second compression type, thereby when server receives the update request message that comprises the second compression type that client sends, if knowing, judgement self supports this second compression type, by current compression algorithm, handle after the current original document that will transmit, with regard to the compression algorithm that application is corresponding with the second compression type, the follow-up original document of client of giving to be transmitted is compressed to processing, and by the compressed file of application the second compression type sign by and client between TCPsocket passage send to client, client knows that this compressed file is that the server application compression algorithm corresponding with the second compression type compressed after applying the compressed file of the second compression type sign, therefore client is applied the compression algorithm corresponding with the second compression type and this compressed file is carried out to decompression is obtained original document, and original document is shown to user by client.
