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
