Question

我正在尝试连接到外部域，并在socketio和socketcluster中进行了相同的测试，出于某种原因，socketio连接可以正常工作，而套接字群集却没有连接

套接字IO代码

        var subscriptionUrl = 'https://streamer.cryptocompare.com/'

        var socket = io.connect(subscriptionUrl)

        socket.emit('SubAdd', {
            subs: ['5~CCCAGG~BTC~USD']
        })

        socket.on("m", function (message) {console.log('got message')}

套接字群集代码

var options = {
                hostname: 'streamer.cryptocompare.com',
                port: 443,
                secure: true,
                rejectUnauthorized: false
            }

        // Initiate the connection to the server
        var socket = socketCluster.create(options);

        socket.on('connect', function () {
            console.log('CONNECTED');
        });

我希望我什么都没错过，不过我发现开发人员工具的“网络”标签下的网址有所不同

未生成响应头我假设console.log中的connect语句至少应该执行，或者如果我忽略了某些内容。某些方向是超级赞赏。谢谢
