Technical Field
The invention relates to the field of data transmission, in particular to a data transmission method, a data transmission system and a data transmission medium based on WebSocket.
Background
With the development of internet technology, in order to realize a push technology, a technology used by many websites is generally Ajax polling. Polling is the HTTP request by the browser to the server at a specific time interval (e.g., every 1 second), and then the server returns the most recent data to the client's browser. In a target monitoring system based on WebGIS, the position and state information of a target are often required to be monitored in real time, the behavior of the target can be alarmed, the target can be monitored, and the requirement can be basically met by a polling request mechanism based on ajax.
However, although the ajax-based polling request mechanism can effectively solve the data communication problem, the traditional mode brings obvious disadvantages that the browser needs to continuously send requests to the server, however, the HTTP request may contain a long header, wherein the really valid data may be only a small part, and obviously, much bandwidth and other resources are wasted.
Fig. 1 shows a schematic operation mode of Ajax and WebSocket. As shown in fig. 1, based on the polling request mode of Ajax, every time data is requested, the process of GET connecting to server- > protocol handshake- > receiving return data is executed, that is, the left side of fig. 1 is indicated by the arrow between the client and the server. Based on the WebSocket push mode, as long as connection is performed once, the server pushes the data to the client as long as the data exists, and the server does not need to be initiated again to connect and receive the data, that is, the client and the server on the right side in fig. 1 interact with the content indicated by the arrow.

Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A first aspect of the present invention provides a data transmission method based on WebSocket, and fig. 2 is a schematic diagram of a flow of the data transmission method based on WebSocket according to an embodiment of the present invention.
As shown in fig. 2, the process starts at step S1, and a WebSocket connection is established between a client and a server, where the client sends an HTTP request to the server, and additional header information of the HTTP request includes upgraded WebSocket connection information. In some embodiments, the client includes, but is not limited to, a browser. The method comprises the steps that a browser of a client initiates a WebSocket connection, firstly, an HTTP request is initiated to a server, the request is different from a common HTTP request and contains some additional header information, wherein the additional header information 'Upgrade: WebSocket' indicates that the request is an HTTP request for applying protocol upgrading, the server analyzes the additional header information and then generates response information to return to the client, and therefore the WebSocket connection between the client and the server is established, the client and the server can freely transmit information through the connection channel, and the connection can continuously exist until the client or one of the server actively closes the connection.
In step S2, through the WebSocket connection, the client sends a subscription request to the server according to a service requirement, so as to establish a subscription and distribution relationship. The browser client sends a subscription request to the server through WebSocket connection according to the service requirement, and the communication can be directly carried out without requesting connection to the server. And the server side responds to the request and establishes a subscription and distribution relation. In some embodiments, the business requirements are, for example: the method comprises the steps that vehicle monitoring is carried out, a user needs to monitor the distribution and the use condition of vehicles of a unit at the current level, the user uses a WebGIS system to send a subscription request to a message server, and the server pushes information such as vehicle position information, speed, direction and state of the unit at the current level to the WebGIS system through requested parameters and user information and Websocket.
In step S3, the client receives the subscription topic data pushed from the server, where the server pushes the subscription topic data based on the subscription distribution relationship. The subscription topic data comprises one or more of location point data, attribute data and alarm data. Specifically, the server finds a browser client WebSocket session through a subscription and distribution relationship, and starts to continuously push subscribed theme data to the client, for example: location point data, attribute data, alarm data, etc.
In some embodiments, the method further includes step S4, where the client performs visualization processing on the received subscription topic data. After receiving the data, the browser client displays the data such as the real-time position, the attribute and the like of the target on the WebGIS; for example: longitude, latitude, altitude, speed, direction, status, etc. of the target location.
FIG. 3 shows a flow diagram of message publishing and subscribing according to an embodiment of the disclosure. As shown in fig. 3, the message producer is generally a GPS or beidou positioning terminal, and after the terminal is connected to the message server, the terminal starts to send message data to a corresponding topic in the message exchange server, and starts to broadcast the message; then the message exchange server pushes the corresponding topic message to a client subscribing the corresponding topic, namely a message consumer; the message consumers can be a plurality of messages, and the same message can be processed differently, including map display, data calculation and the like. The messages are automatically pushed to the client by the message exchange server through WebSocket data transmission, and the client only needs to be connected to the message exchange server and subscribe to corresponding topics.
To sum up, the data transmission method based on the WebSocket in the first aspect of the present invention has the following technical effects:
1) less control overhead: when data is exchanged between the server and the client after the connection is created, the header of the packet for protocol control is relatively small. Without the inclusion of an extension, this header size is only 2 to 10 bytes (relative to the packet length) for server-to-client content; for client-to-server content, this header also needs to be added with an additional 4-byte mask. This overhead is significantly reduced relative to HTTP requests that each time carry a complete header.
2) Stronger real-time performance: because the protocol is full duplex, the server can actively send data to the client at any time. Compared with the HTTP request, the response can be realized only by waiting for the client to initiate the request server, so that the delay is obviously less; it can deliver data more times in a short time even in comparison with Comet and the like, which are long polls.
3) Maintaining the connection state: unlike HTTP, WebSocket requires a connection to be created first, which makes it a stateful protocol, and then partial state information can be omitted during communication. And HTTP requests may need to carry state information (e.g., authentication, etc.) at each request.
4) Better binary support: WebSocket defines binary frames, which can handle binary content more easily than HTTP.
5) Extensions can be supported: the WebSocket defines the extension, and a user can extend a protocol and realize a partially customized subprotocol, such as compression supported by a partial browser.
6) Better compression effect: compared with HTTP compression, WebSocket can continue the context of the previous content under the support of proper expansion, and can remarkably improve the compression rate when similar data is transferred.
A second aspect of the present invention provides a data transmission system based on WebSocket, and fig. 4 is a structural diagram of the data transmission system based on WebSocket according to the embodiment of the present invention. As shown in fig. 4, the system includes a client 401 and a server 402, and a WebSocket connection is established between the client 401 and the server 402. The client 401 is configured to: sending a subscription request to the server 402 according to a service requirement via the WebSocket connection to establish a subscription and distribution relationship; and receiving the subscription topic data pushed by the server side 402, wherein the server side 402 pushes the subscription topic data based on the subscription distribution relationship.
In the system provided by the second aspect of the present invention, in the process of establishing the WebSocket connection between the client 401 and the server 402, the client 401 is configured to send an HTTP request to the server 402, where additional header information of the HTTP request includes upgraded WebSocket connection information.
According to a second aspect of the present invention there is provided a system wherein the subscription topic data comprises one or more of location point data, attribute data, alert data.
The system according to the second aspect of the present invention, wherein the client 401 is further configured to: and carrying out visualization processing on the received subscription theme data.
The data transmission system based on the WebSocket in the second aspect of the invention has the following technical effects:
1) system decoupling: there is no direct calling relation between interactive systems, only through message transmission, so the system intrusiveness is not strong, the coupling degree is low, different systems are independent and can be linked with each other.
2) Providing services for big data processing architectures: by using the message as integration, the message queue is also integrated with a real-time processing architecture in the context of big data, and performance support is provided for data processing.
3) Expansibility: because the message queue decouples the processing, it is easy to increase the frequency of message enqueuing and processing, as long as the processing is additionally increased; the code and the parameters do not need to be changed and adjusted, thereby facilitating the distributed capacity expansion.
4) Overload protection: in case of a drastic increase in the amount of access, the application still needs to continue to function, but such burst traffic cannot extract the prediction; it is clearly a huge waste if resources are put on standby at any time in order to be able to handle such instantaneous peak accesses. The use of message queues enables critical components to withstand burst access pressures without crashing completely due to burst overloaded requests.
5) Recoverability: when a part of components of the system fail, the whole system is not influenced. Message queues reduce the degree of coupling between processes so that even if a process that processes a message hangs, messages that are enqueued can still be processed after the system resumes.
6) And (3) ensuring the sequence: in most use scenes, the data processing sequence is important, especially in a target monitoring system, the point positions and the time of targets are in one-to-one correspondence, and the sequence requirement is particularly high. Most message queues are inherently ordered and ensure that data is processed in a particular order.
7) Buffering: in any important system, there will be elements that require different processing times. The message queue facilitates the most efficient execution of tasks through a buffer layer that helps control and optimize the speed of data flow through the system to adjust system response time.
A third aspect of the present invention provides a non-transitory computer-readable medium storing instructions that, when executed by a processor, perform the steps in the WebSocket-based data transmission method according to the first aspect of the present invention.
In conclusion, the technical scheme of the invention establishes a data sharing synchronization mechanism based on WebSocket, and a fast channel with long connection is formed between the browser and the server, so that the browser and the server can directly transmit data to each other; the trouble of actively sending the polling request of the server in the past is changed, the pressure of the service can be reduced, and the whole response capability of the system and the real-time display effect of the system are improved. Meanwhile, a dynamic message data subscription and distribution mechanism based on the WebSocket protocol is realized, and the problem of synchronous data sharing between the browser client and the server is solved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
