使用nodejs客户端访问golang websocket服务器

我认为this正是你要找的 . 使用服务器代码的快速示例：

var WebSocketClient = require('websocket').client;

var client = new WebSocketClient();

client.on('connectFailed', function(error) {
    console.log('Connect Error: ' + error.toString());
});

client.on('connect', function(connection) {
    console.log('WebSocket client connected');
    connection.on('error', function(error) {
        console.log("Connection Error: " + error.toString());
    });
    connection.on('close', function() {
        console.log('echo-protocol Connection Closed');
    });
    connection.on('message', function(message) {
        if (message.type === 'utf8') {
            console.log("Received: '" + message.utf8Data + "'");
        }
    });

    connection.sendUTF("Hello world");
});

client.connect('ws://127.0.0.1:8082/echo', "", "http://localhost:8082");

lib/WebSocketCLient.js

//this.failHandshake("Expected a Sec-WebSocket-Protocol header.");
        //return;

由于某种原因，您提供的websocket库似乎没有发送“Sec-Websocket-Protocol”标头，或者至少客户端找不到它 . 我没有做太多的测试，但是应该在某个地方提交错误报告 .

以下是使用Go客户端的示例：

package main

import (
    "fmt"
    "code.google.com/p/go.net/websocket"
)

const message = "Hello world"

func main() {
    ws, err := websocket.Dial("ws://localhost:8082/echo", "", "http://localhost:8082")
    if err != nil {
        panic(err)
    }
    if _, err := ws.Write([]byte(message)); err != nil {
        panic(err)
    }
    var resp = make([]byte, 4096)
    n, err := ws.Read(resp)
    if err != nil {
        panic(err)
    }
    fmt.Println("Received:", string(resp[0:n]))
}
