我想从C程序或Chrome扩展程序Smart Websocket客户端连接到node.js + socket.io中写入的websocket服务器,但我不能。 我只能从其他nodejs应用程序或js + socket.io连接到它。从C程序连接到node.js websocket服务器

的Node.js服务器:

var app = require('http').createServer(handler) 
var io = require('socket.io')(app); 
var fs = require('fs'); 

app.listen(3000); 

function handler (req, res) { 
    fs.readFile(__dirname + '/index.html', 
    function (err, data) { 
    if (err) { 
     res.writeHead(500); 
     return res.end('Error loading index.html'); 
    } 

    res.writeHead(200); 
    res.end(data); 
    }); 
} 

io.on('connection', function (socket) { 
    socket.emit('news', { hello: 'world' }); 
    socket.on('my other event', function (data) { 
    console.log(data); 
    }); 
}); 

C客户(我用github.com/payden/libwsclient):

#include <time.h> 
#include <wsclient/wsclient.h> 
#include <errno.h> 


int onopen(wsclient *c) { 
    printf("ad\n"); 
    fprintf(stderr, "onopen called: %d\n", c->sockfd); 
    libwsclient_send(c, "Hello onopen"); 
    return 0; 
} 


void initSocketConnection() { 
    //char *host = "ws://echo.websocket.org"; 
    char *host = "ws://127.0.0.1:3000"; 

    wsclient *client = libwsclient_new(host); 

    if(!client) { 
     fprintf(stderr, "Unable to initialize new WS client.\n"); 
     exit(1); 
    } 
    printf("connecrionnn \n"); 
    libwsclient_onopen(client, &onopen); 

    char *msg = "{\"msg\":\"STATION_READY_FOR_ACTION\", \"appKey\":\"secret-key\"}"; 
    libwsclient_send(client, msg); 
} 

我在做什么错?

您是否收到任何错误? – nilobarp

没有错误。为什么我无法通过Chrome扩展程序连接? C程序连接到ws://echo.websocket.org,到localhost no。 – user7213585

我解决了问题,套接字端点必须 “WS://127.0.0.1:3000/socket.io/EIO = 3 &运输= WebSocket的”
