javascript - 如何连接Websocket API？

Question

我尝试查询的 API 是:https://socket.etherdelta.com

API 文档位于:https://github.com/etherdelta/etherdelta.github.io/blob/master/docs/API.md

当我尝试执行简单的获取请求时:https://socket.etherdelta.com/getmarkets它给了我一条错误消息“Cannot GET/getmarkets”

这是我试图用来获取市场信息的代码:

var request = require('request');
var url = 'https://socket.etherdelta.com/getMarket';


request(url , (err, res, body) => {
try{
var json = JSON.parse(body);
console.log(json);


}catch(err){
console.log('parsing error');
console.log(body);
}
});

将其编辑为:

var WebSocket = require('ws')
var ws = new WebSocket('wss://socket.etherdelta.com')

ws.onopen = function(){
ws.send(JSON.stringify("getMarket"))

};

ws.onmessage = function(msg){
var response = JSON.parse(msg.data);
console.log(response);
};

这个 API 似乎在 WSS 协议(protocol)上运行，而不是 HTTPS。您能尝试一下像ws这样的网络套接字客户端库吗？带有以下网址

wss://socket.etherdelta.com
