Bittrex WebSocket编码方式是什么？附Chrome模拟连接方法

Great question! Let's break this down clearly for you:

1. WebSocket Encoding Method #

Bittrex's WebSocket implementation (built on SignalR) uses JSON encoding for message serialization. This is the default format for SignalR communications, so all data exchanged between the client and server will be structured as JSON objects.

2. Simulating the Connection with Chrome DevTools #

You're right that this process is straightforward once you know the steps—here's a detailed walkthrough:

• First, send a GET request to retrieve your unique ConnectionToken. You can run this directly in Chrome DevTools' Network tab or Console:

  https://socket.bittrex.com/signalr/negotiate?clientProtocol=1.5&connectionData=%5B%7B%22name%22%3A%22c2%22%7D%5D&_=1524596108843
  

• The response will include a ConnectionToken field (like the example you shared: "gbLsm8C6Jck1mQTTFjmuIv5qgUuMZz/kXU1s+fAnjnW qUFQocNBfp3VOrd/y0acxWL5Fv7MZ54heRddLYZS+EMhLnaPPQiSZblvgJPCbLKqZTIkb"). Copy this token—you’ll need it for the next step.
• Finally, initiate the WebSocket connection using a wss endpoint, replacing the placeholder with your retrieved token. The base connection URL looks like this:

  wss://socket.bittrex.com/signalr/connect?transport=webSockets&clientProtocol=1.5&connectionToken=YOUR_TOKEN_HERE&connectionData=%5B%7B%22name%22%3A%22c2%22%7D%5D&tid=7
  

  Swap YOUR_TOKEN_HERE with the token you copied earlier, and you’ll have an active WebSocket connection to Bittrex.
