1 Four data streams

1. Simple mode
2. Server side data flow mode
3. Client data stream mode
4. Two way data flow pattern

2 Server data flow

This mode is that the client sends a request together , The server returns a continuous data stream . A typical example is that the client sends a stock code to the server , The server will continuously return the implementation data source of the stock to the client .

3 Client data stream

Contrary to the server-side data flow pattern , This time, the client sends data stream to the server , And after the end of the transmission , The server returns a response . A typical example is the Internet of things terminal sending data to the server .

4 Bidirectional data flow

seeing the name of a thing one thinks of its function , This is that both the client and the server can send data streams to each other , At this time, the data of both sides can be sent to each other at the same time , In other words, real-time interaction can be realized . A typical example is a chat robot .
