Description
技术领域technical field
本发明实施例涉及通信技术领域，尤其涉及一种websocket协议的数据传输方法、设备和系统。The embodiment of the present invention relates to the field of communication technology, and in particular to a data transmission method, device and system of the websocket protocol.
背景技术Background technique
很多网站为了实现即时通讯采用轮询技术，即在特定的时间间隔，由客户端对服务器发出HTTP请求，然后由服务器返回最新的数据给客户端。这种传统模式带来很明显的缺点是客户端需要不断的向服务器发出请求，然而HTTP请求的报文头是非常长的，里面包含的数据可能只是一个很小的值，这样会占用很多的带宽。Many websites use polling technology to implement instant messaging, that is, at a specific time interval, the client sends an HTTP request to the server, and then the server returns the latest data to the client. The obvious disadvantage of this traditional mode is that the client needs to continuously send requests to the server. However, the header of the HTTP request is very long, and the data contained in it may only be a small value, which will take up a lot of time. bandwidth.
为了解决上述问题，实现了客户端与服务器全双工通信(full-duplex)，HTML5中采用WebSocket协议，基于WebSocket协议，客户端和服务器只需要要做一个握手的动作，然后，客户端和服务器之间就形成了一条快速通道，两者之间就直接可以实现数据互相实时传送。但是，现有技术中，客户端与服务器之间的websocket的报文采用直接传输方式，因此，在实际应用中随着通信交互内容的海量增加，影响了数据传输的效率。In order to solve the above problems, full-duplex communication (full-duplex) between the client and the server is realized. The WebSocket protocol is adopted in HTML5. Based on the WebSocket protocol, the client and the server only need to do a handshake action, and then, the client and the server A fast channel is formed between them, and the two can directly transmit data to each other in real time. However, in the prior art, the websocket messages between the client and the server are directly transmitted. Therefore, in practical applications, the efficiency of data transmission is affected with the massive increase of communication interaction content.

具体实施方式detailed description
图1为本发明实施例提供的一个websocket协议的数据传输方法的流程图，如图1所示，该方法包括：Fig. 1 is the flow chart of the data transmission method of a websocket agreement that the embodiment of the present invention provides, as shown in Fig. 1, this method comprises:
步骤100，支持websocket的服务器与支持websocket的客户端协商所共同支持的压缩类型信息，根据所述压缩类型信息确定与待传输给所述客户端的原始文件的类型匹配的第一压缩类型；Step 100, the server that supports websocket negotiates with the client that supports websocket about the compression type information that they support, and determines the first compression type that matches the type of the original file to be transmitted to the client according to the compression type information;
支持websocket的服务器在接收支持websocket的客户端发送的访问请求，以及根据访问请求向客户端返回用户所需要的原始文件之前，服务器首先与客户端协商所共同支持的压缩类型信息，协商过程具体包括：客户端向服务器发送自身所支持的压缩类型信息，比如gzip、rar、zip、cab、7z、tar等等，服务器根据自身所支持的压缩类型信息与客户端发送的压缩类型信息进行比较，选取相同的压缩类型作为双方所共同支持的压缩类型信息，并反馈给客户端。然后服务器从双方所共同支持的压缩类型信息中确定与待传输给客户端的原始文件的类型匹配的第一压缩类型，具体的确定过程为服务器本地存储有文件类型与压缩类型的对应关系，该对应关系是基于本领域技术人员应用与不同的压缩类型对应的压缩算法对不同类型的文件进行压缩效率测试所获取的，从而服务器查询该对应关系获取与待传输给客户端的原始文件的类型匹配的第一压缩类型。Before the websocket-supporting server receives the access request sent by the websocket-supporting client and returns the original file required by the user to the client according to the access request, the server first negotiates with the client about the compression type information it supports. The negotiation process specifically includes : The client sends the compression type information it supports to the server, such as gzip, rar, zip, cab, 7z, tar, etc., and the server compares the compression type information supported by itself with the compression type information sent by the client, and selects The same compression type is used as the compression type information supported by both parties, and is fed back to the client. Then the server determines the first compression type that matches the type of the original file to be transmitted to the client from the compression type information supported by both parties. The specific determination process is that the server locally stores the correspondence between the file type and the compression type. The relationship is based on those skilled in the art applying compression algorithms corresponding to different compression types to perform compression efficiency tests on different types of files, so that the server queries the corresponding relationship to obtain the first file that matches the type of the original file to be transmitted to the client. A compression type.
步骤101，所述服务器应用与所述第一压缩类型对应的压缩算法对所述原始文件进行压缩处理，并通过与所述客户端之间的TCPsocket通道将应用所述第一压缩类型标识的压缩文件发送给所述客户端，以供所述客户端应用与所述第一压缩类型对应的压缩算法对所述压缩文件进行解压缩处理获取所述原始文件。Step 101, the server applies the compression algorithm corresponding to the first compression type to compress the original file, and applies the compression identified by the first compression type through the TCP socket channel with the client. The file is sent to the client, so that the client applies a compression algorithm corresponding to the first compression type to decompress the compressed file to obtain the original file.
服务器确定与待传输给客户端的原始文件的类型匹配的第一压缩类型之后，应用与第一压缩类型对应的压缩算法对该原始文件进行压缩处理，需要说明的是，应用压缩算法对该原始文件进行压缩处理属于现有技术，此处不再赘述，仅仅以gzip压缩算法为例简单说明，比如应用gzip压缩算法压缩HTML文件的过程为：寻找输入数据内的重复字符串，二次出现的字符串由一个指向前一字符串的指针代替，其中，指针以对的形式--距离和长度来表示，假如距离限定为32KB，长度限定为258字节，若二次出现的字符串没有在这前32KB内出现，它就会作为文字字节序列发出。进一步地，为了提高压缩效率，服务器在对原始文件进行压缩处理之前，首先判断该原始文件的大小是否大于等于预设的阈值，若判断获知该原始文件的大小大于等于该阈值，则应用与第一压缩类型对应的压缩算法对原始文件进行压缩处理，若判断获知该原始文件的大小小于该阈值，则将该原始文件移入缓存区，达到预设的缓存时间后，再应用与第一压缩类型对应的压缩算法对存入缓存区的一个或多个原始文件进行压缩处理。服务器在对原始文件进行压缩处理完成后，将应用第一压缩类型标识的压缩文件通过与客户端之间的TCPsocket通道发送给客户端，客户端接收应用第一压缩类型标识的压缩文件后获知该压缩文件是服务器应用与第一压缩类型对应的压缩算法进行压缩的，因此客户端则应用与第一压缩类型对应的压缩算法对该压缩文件进行解压缩处理获取原始文件，并将原始文件通过客户端显示给用户。After the server determines the first compression type that matches the type of the original file to be transmitted to the client, it applies the compression algorithm corresponding to the first compression type to compress the original file. It should be noted that the original file is compressed using the compression algorithm Compression processing belongs to the prior art, so I won’t go into details here, and just take the gzip compression algorithm as an example for a brief description. For example, the process of applying the gzip compression algorithm to compress HTML files is: looking for repeated strings in the input data, characters that appear twice The string is replaced by a pointer to the previous string, where the pointer is expressed in the form of a pair - distance and length. If the distance is limited to 32KB, the length is limited to 258 bytes. If the string that appears twice is not here appears within the first 32KB, it is emitted as a sequence of literal bytes. Further, in order to improve the compression efficiency, before compressing the original file, the server first judges whether the size of the original file is greater than or equal to a preset threshold, and if it is judged that the size of the original file is greater than or equal to the threshold, then apply and A compression algorithm corresponding to a compression type compresses the original file. If it is judged that the size of the original file is smaller than the threshold, the original file is moved into the cache area. After the preset cache time is reached, the first compression type is applied. The corresponding compression algorithm performs compression processing on one or more original files stored in the cache area. After the server compresses the original file, it sends the compressed file marked with the first compression type to the client through the TCP socket channel with the client, and the client knows the compressed file after receiving the compressed file marked with the first compression type The compressed file is compressed by the server using the compression algorithm corresponding to the first compression type, so the client applies the compression algorithm corresponding to the first compression type to decompress the compressed file to obtain the original file, and passes the original file through the client displayed to the user.
本实施例提供的websocket协议的数据传输方法，首先支持websocket的服务器通过与支持websocket的客户端协商所共同支持的压缩类型信息，然后确定与待传输的原始文件的类型匹配的第一压缩类型，应用与第一压缩类型对应的压缩算法对原始文件进行压缩处理，并通过TCPsocket通道将应用第一压缩类型标识的压缩文件发送给客户端，客户端应用与第一压缩类型对应的压缩算法对压缩文件进行解压缩处理获取原始文件，从而提高了客户端与服务器指间基于websocket协议的数据传输效率。In the data transmission method of the websocket protocol provided by this embodiment, first, the server supporting websocket negotiates with the client supporting the websocket to jointly support the compression type information, and then determines the first compression type that matches the type of the original file to be transmitted, Apply the compression algorithm corresponding to the first compression type to compress the original file, and send the compressed file marked with the first compression type to the client through the TCP socket channel, and the client applies the compression algorithm corresponding to the first compression type to compress the original file. The file is decompressed to obtain the original file, thereby improving the data transmission efficiency between the client and the server based on the websocket protocol.
基于上述实施例，进一步地，所述方法还包括：当客户端需要应用第二压缩类型进行解压缩时，可以主动向服务器发送包括第二压缩类型的变更请求，从而当服务器接收客户端发送的包括第二压缩类型的更新请求消息，若判断获知自身支持该第二压缩类型，则用当前的压缩算法处理完当前要传输的原始文件后，就应用与第二压缩类型对应的压缩算法对后续待传输给客户端的原始文件进行压缩处理，并将应用第二压缩类型标识的压缩文件通过与客户端之间的TCPsocket通道发送给客户端，客户端接收应用第二压缩类型标识的压缩文件后获知该压缩文件是服务器应用与第二压缩类型对应的压缩算法进行压缩的，因此客户端则应用与第二压缩类型对应的压缩算法对该压缩文件进行解压缩处理获取原始文件，并将原始文件通过客户端显示给用户。Based on the above embodiment, further, the method further includes: when the client needs to apply the second compression type for decompression, it can actively send a change request including the second compression type to the server, so that when the server receives the Including the update request message of the second compression type, if it is judged that it supports the second compression type, after the original file to be transmitted is processed by the current compression algorithm, the compression algorithm corresponding to the second compression type is applied to the subsequent The original file to be transmitted to the client is compressed, and the compressed file with the second compression type identification is sent to the client through the TCP socket channel between the client and the client. After receiving the compressed file with the second compression type identification, the client knows The compressed file is compressed by the server using the compression algorithm corresponding to the second compression type, so the client uses the compression algorithm corresponding to the second compression type to decompress the compressed file to obtain the original file, and pass the original file through displayed to the user by the client.
