deb*_*kar 1 javascript websocket reactjs cryptocurrency binance
这是我的客户端代码库。它正在与交换 websocket 之一一起使用,但不与此 websocket 一起使用。有什么建议么?
websocket参考:https://github.com/binance-exchange/binance-official-api-docs/blob/master/web-socket-streams.md
import React, { Component, createContext } from "react";
export const Contx = createContext();
export class ConProvider extends Component {
state = {
coins: [],
digCoin: [],
sou: [],
passSocket: undefined
};
componentDidMount() {
this.socketCall();
}
socketCall = () => {
var ws = new WebSocket("wss://stream.binance.com:9443");
var msg = {
"method": "SUBSCRIBE",
"params": "btcusdt@depth",
"id": 1
};
ws.onopen = () => {
ws.send(msg);
};
ws.onmessage = e => {
const value = e.data;
this.setState({
coins: value
});
};
this.setState({
passSocket: ws
});
};
socketClose = () => {
var wss = this.state.passSocket;
wss.close();
};
render() {
console.log(this.state.coins);
// console.log(this.state.coins)
return (
<Contx.Provider
value={{
...this.state,
socketCall: this.socketCall,
socketClose: this.socketClose
}}
>
{this.props.children}
</Contx.Provider>
);
}
}

const ws = new WebSocket('wss://stream.binance.com:9443/ws');
const msg = {
method: 'SUBSCRIBE',
params: ['btcusdt@depth'],
id: 1,
};
ws.onopen = () => {
ws.send(JSON.stringify(msg));
};

Send 接受 JSON 格式,我将 msg 更改为 object,将数组传递给 params 并添加 /ws,如上所述。
