Cannot access Coinex via WebSocket on Windows #3173

Closed quejp closed 5 months ago

quejp commented 5 months ago

Hello owner.

When I run the test code below, I cannot connect to the WebSocket server. If it is possible to avoid this, could you please tell me how to do so? The operating system is Windows 11. The version of Visual Studio used is toolset 2022 v143. The version of libwebsockets used is v4.3.3. The version of OpenSSL used is v3.3.0.

If you set the cmake options LWS_TLS_LOG_PLAINTEXT_RX=1 and LWS_TLS_LOG_PLAINTEXT_TX=1, you can see exactly what you're sending and receiving.

502 means the remote server didn't like something, such as requiring auth headers or somesuch (it's up to them to decide what they like or not). You might get some extra information from the returned 502 body.

Thank you for your advice. I will try it.

quejp commented 5 months ago

@lws-team I changed the cmake build options and ran it. I tried to analyze it in my own way, but since I don't have much knowledge of HTTP headers or the WebSocket protocol, I couldn't figure out what fundamentally was causing the server to reject it. From this message exchange, do you have any ideas as to what the cause might be?

The remote server can set whatever rules it likes for liking what you send. Usually, some kind of auth, eg with an "api key" in what you send is going to be required. A 30s google shows https://docs.coinex.com/api/v2/authorization

quejp commented 5 months ago

I found the cause. In conclusion, it seems that the following header information was the cause. Their server does not recognize the Sec-WebSocket-Protocol item, and it seems to be rejected if this information is included. "Sec-WebSocket-Protocol: COINEX protocol"

Therefore, I modified the code below and the connection was successful. ws.stLwsConInfo.protocol = NULL;// g_WsProtocols[0].name;

For anyone having the same problem, I will provide the steps I took to debug it.

Can connect using Node.js WebSocket. Therefore, I decided to monitor the http header when connecting with Node.js.

Node.js websocket http header request headers: { 'Sec-WebSocket-Version': 13, 'Sec-WebSocket-Key': 'g4q5OTKmU+ql6pg5semqKQ==', Connection: 'Upgrade', Upgrade: 'websocket', 'Sec-WebSocket-Extensions': 'permessage-deflate; client_max_window_bits' },

DEBUG test code on node.js

const WebSocket = require('ws');

const socketUrl = 'wss://socket.coinex.com/v2/spot';

// Dump http header on Node.js websocket
function logHttpRequest(options, callback) {
    const originalRequest = (options.protocol === 'https:' ? require('https') : require('http')).request;

    const req = originalRequest(options, (res) => {
        console.log('Status Code:', res.statusCode);
        console.log('Headers:', res.headers);

        res.on('data', (chunk) => {
            console.log('Response Body:', chunk.toString());
        });

        res.on('end', () => {
            console.log('No more data in response.');
        });

        if (callback) {
            callback(res);
        }
    });

    req.on('error', (e) => {
        console.error(`Request error: ${e.message}`);
    });

    return req;
}

const ws = new WebSocket(socketUrl, {
    createConnection: (options) => {
        console.log('Request Options:', options);
        return logHttpRequest(options);
    }
});

ws.on('open', () => {
    console.log('Connected to the WebSocket server');

});

ws.on('message', (data) => {
    const message = JSON.parse(data);
    console.log('Received message:', message);
});

ws.on('close', () => {
    console.log('Disconnected from the WebSocket server');
});

ws.on('error', (error) => {
    console.error('WebSocket error:', error);
});
