How to cancel a thread making a http request from another thread

Question

Any suggestion on how do we kill a thread which has made a http post request and waiting till getting response. I want to kill this thread from another thread running parallely before it could receive any response from request. I got suggestion to close or abort the http post request but did not workout, can anyone suggest how can we abort the http request in this scenario or any other way to achieve this.

The only way to stop a Thread is to interrupt it. Either the Thread’s run method will respond properly to the interrupt, or it won’t. If it doesn’t, there is nothing else you can do. — VGR, Jul 14 '17 at 14:36

Give some more details what http client you use. Do you use a third party library? (eg. Apache HTTP Client) It all depends HOW you do it. Interrupting the thread will wirk in most cases i guess. I suggest you read the documentation of the client you use. — Ortwin Angermeier, Jul 15 '17 at 10:38

The thread that made the request is blocked while waiting the server to respond. If you take a thread dump and see, it will be in some read() method, but not on a Thread.sleep. So calling interrupt() will not have an effect (unless it's an InterruptibleChannel). Do you have access to the socket or the output stream on which the POST request was made? If so, you can close that, which will bring out of the read wait with an exception. Do you have a code sample that you can put up?

you are right if we do thread.getState() on the thread during the wait for response we will get state as RUNNING. Due to which when interrupt is triggered the interrupt flag of the thread gets set but thread will be killed gracefully after finishing the request. – Muzammil Shareef Jul 15 '17 at 18:06

Iam using apache http client and I cannot use asynchttp. I tried using one thread to send the request and ex:ReqThread and cancel listener thread ex:CancelThread and I have a shared variable object holding httpPost object. actual request happens in class A and it uses httpPost sent by ReqThread for sending request. I have cancel event listening implementation in CancelThread which reads the httpPost set by ReqThreaad in shared object to issue**httppost.abort()**. Here is the problem where Iam getting httpPost object as null. – Muzammil Shareef Jul 15 '17 at 18:15

Helloo everyone, finally got this closing socket idea implemented and working. below is the snippet i tried.

my Requesting thread

package com.pkg.myhttptest;

import org.apache.http.client.methods.HttpPost;

public class RequestThread implements Runnable{

    Message msg = null;
    Util util = null;
    public RequestThread(Message msg, Util util) {
        this.msg = msg;
        this.util = util;
    }
    public void run() {
        System.out.println("its request thread");
        util.print(msg);
    }



}

Cancelling Thread

public class CancelThread implements Runnable {
    Message msg = null;
    Util util = null;
    public CancelThread(Message msg, Util util) {
        this.msg = msg;
        this.util = util;
    }
    public void run() {
        System.out.println("its cancel thread");
        int i=0;
        while(i<5){
            System.out.println("looping" + i);
            i++;
        }
        System.out.println(msg.getHttpost() + "In cancelled");
        Header[] hdr = msg.getHttpost().getAllHeaders();
        System.out.println(hdr.length + "length");
        msg.getHttpost().abort();
        System.out.println(msg.getHttpost().isAborted());

    }

}

Shared Object

public class Message {

    HttpPost httpost;

    public HttpPost getHttpost() {
        return httpost;
    }

    public void setHttpost(HttpPost httpost) {
        this.httpost = httpost;
    }
}

Util Class

public class Util {
    private final String USER_AGENT = "Mozilla/5.0";

    public void print(Message msg) {
        String url = "https://selfsolve.apple.com/wcResults.do";
        HttpPost post = new HttpPost(url);
        HttpClient client = HttpClientBuilder.create().build(); 
        post.setHeader("User-Agent", USER_AGENT);

        List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
        urlParameters.add(new BasicNameValuePair("sn", "C02G8416DRJM"));
        urlParameters.add(new BasicNameValuePair("cn", ""));
        urlParameters.add(new BasicNameValuePair("locale", ""));
        urlParameters.add(new BasicNameValuePair("caller", ""));
        urlParameters.add(new BasicNameValuePair("num", "12345"));

        try {
            post.setEntity(new UrlEncodedFormEntity(urlParameters));
            msg.setHttpost(post);
            HttpResponse response = client.execute(post);
            System.out.println("Response Code : " + response.getStatusLine().getStatusCode());

            BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

            StringBuffer result = new StringBuffer();
            String line = "";
            while ((line = rd.readLine()) != null) {
                result.append(line);
            }
        } catch (UnsupportedEncodingException e) {

        } catch (IOException e) {
           e.printStackTrace()
        }
    }

Main Class

public class App 
{
    public static void main( String[] args )
    {
        Message msg = new Message();
        Util util = new Util();

        Thread reqThread = new Thread(new RequestThread(msg, util));
        Thread cancelThread = new Thread(new CancelThread(msg, util));

        System.out.println("Starting Threads");
        reqThread.start();
        try {
            reqThread.sleep(2000);
            cancelThread.start();
            cancelThread.join();
            System.out.println("closing..");
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

Its little uncleaned code I agree, but it works. It results in below exception and kills the thread.

java.net.SocketException: Socket is closed
    at java.net.Socket.getInputStream(Socket.java:876)
    at sun.security.ssl.SSLSocketImpl.doneConnect(SSLSocketImpl.java:644)
    at sun.security.ssl.SSLSocketImpl.<init>(SSLSocketImpl.java:549)

Thanks everyone who has put their efforts in helping me.

I was trying to solve the same thing. I wrote an HTTP Request Runnable that took 20 seconds to timeout and executed on one thread (1st Thread). I wrote a Timeout Runnable on a separate thread (2nd Thread) that was supposed to interrupt/stop the 1st Thread after 10 seconds. For every second in the Main Thread (3 threads total), I printed the state of the threads and found the 1st thread kept running.

I use a SharedData class to hold information needed by both threads. By adding the extra information needed to terminate the thread (ie the HttpGet), I can have the monitoring thread do whatever is necessary to actually terminate the thread (ie call httpGet.abort).
