Module request in nodejs don't stop pipe - node.js

Question

I have used dicer for parsing pipe by request but I don't know which command for stop pipe.
dicer.on('part', function(part) {
var frameEncoded = '';
part.setEncoding('base64');
part.on('header', function(header) { });
part.on('data', function(data) { frameEncoded += data; });
part.on('end', function() { console.log(frameEncoded); });
});
var options = {
method: 'GET',
uri: 'http://192.168.1.2/video.mjpeg/'
}
request(options).pipe(dicer)
//only for test
setTimeout(function() {
console.log('stop request.pipe');
var options = {
method: 'GET',
uri: 'http://192.168.1.2/video.mjpeg/'
}
request(options).end() //<-- ?? which command?? This not work...
}, 5000);
The uri pointing to a stream of ipcamera and impossible grab event connection close of request because stream it's infinite.

Answer 1

One way to get access to the underlying socket for the request is to listen for the socket event on the request object. Then it's just a matter of closing that socket. For example:
var req = request(options);
req.on('socket', function(sock) {
setTimeout(function() {
console.log('stop request.pipe');
sock.end(); // or sock.destroy();
}, 5000);
});
req.pipe(dicer);
Note though, the request may not have started yet when the socket event is emitted. The socket event basically lets you know that a socket has been assigned to be used for the request (this is especially useful when you are using an http Agent that has maxSockets set to some finite value so you may not necessarily get assigned a socket right away).
You could also try:
var req = request(options);
req.on('response', function(res) {
setTimeout(function() {
console.log('stop request.pipe');
res.socket.end(); // or res.socket.destroy();
}, 5000);
});
req.pipe(dicer);

#mscdex's method works for me. Here is the code :-
request("https://www.linkedin.com/afhdjalsdjhdks")
.on("error", function (error) { process.stderr.write(error.code) })
.on("response", function (resp) {
if ((resp.statusCode !== 200) && (resp.statusCode !== 201)) {
process.stderr.write(format("%s - %s", resp.statusCode, resp.statusMessage))
resp.socket.destroy()
}
})
// .pipe(StreamAll())
.pipe(process.stdout)
