httpurlconnection

I am writing a REST client for CouchDB in Java. The following code should be quite standard: this.httpCnt.connect(); Map<String, String> responseHeaders = new HashMap<>(); int i = 1; while (true){ String headerKey = this.httpCnt.getHeaderFieldKey(i); if (headerKey == null) break; responseHeaders.put(headerKey, this.httpCnt.getHeaderField(i)); i++; } InputStreamReader reader = new InputStreamReader(this.httpCnt.getInputStream()); StringBuilder responseBuilder = new StringBuilder(); char[] buffer = new char[1024]; while(true){ int noCharRead = reader.read(buffer); if (noCharRead == -1){ reader

I am uploading string and photo.and its working fine. Now I want to show progress bar while uploading data with percentage but percentage show very quickly to 100 percentage and take some more time to upload and finally come to the post execute method. protected class upload_images extends AsyncTask<String, Integer, String> { ProgressDialog progressDialog; @Override protected void onPreExecute() { super.onPreExecute(); // showDialog(progress_bar_type); progressDialog = new ProgressDialog(Accept_Report.this); progressDialog.setCancelable(false); // dialog.setCanceledOnTouchOutside(false);

I'm using HttpURLConnection to do download of pages in Java. I forgot to release the connections and I think this was causing some problems to my system (a webcrawler). Now I've done some tests and see that after disconnecting, some connections still like TIME_WAIT in the results from the netstat command on Windows. How I do to free this connection immediately? Example code: private HttpURLConnection connection; boolean openConnection(String url) { try { URL urlDownload = new URL(url); connection = (HttpURLConnection) urlDownload.openConnection(); connection.setInstanceFollowRedirects(true);

The Problem An app I'm maintaining keeps getting socket timeouts after approximately 21000 ms, despite the fact that I've explicitly set longer timeouts. This seemingly magical value of 21000 ms has come up in a few other SO questions and answers, and I'm trying to figure out exactly where it comes from. Here's the essence of my code: HttpURLConnection connection = null; try { URL url = new URL(urlString); connection = (HttpURLConnection) url.openConnection(); connection.setConnectTimeout(45000); connection.setReadTimeout(90000); int responseCode = connection.getResponseCode(); if

I am trying to do a GET request with some parameters in Java using HttpURLConnection. Everytime I do this however, I get a 400: Bad Request each time. What do I need to change to make it work? String url = "http://www.awebsite.com/apath?p1=v1&p2=v2&p3=v3"; HttpURLConnection conn = (HttpURLConnection)new URL(url).openConnection(); conn.setDoInput(true); conn.setDoOutput(false); conn.setUseCaches(false); conn.setRequestMethod("GET"); conn.setRequestProperty("Host", "www.awebsite.com"); conn.setRequestProperty("User-Agent", "Mozilla/4.0"); conn.setRequestProperty("Accept", "text/html,application

I am copying this method verbatim from my application, which isn't complete yet but it does attempt to provide me with a timeout stack trace if things don't go smoothly: protected boolean isHttpAlive() { boolean isHttpOk = false; HttpURLConnection httpConnection = null; try { URL gurl = new URL("http://www.amazon.com/"); URLConnection connection = gurl.openConnection(); connection.setConnectTimeout(5 * 1000); // 5 seconds! httpConnection = (HttpURLConnection) connection; int responseCode = httpConnection.getResponseCode(); if (responseCode == HttpURLConnection.HTTP_OK) isHttpOk = true; } catch

I've written a programm that opens a httpurlconnection to a website through random proxies. My httpurlconnection is called conn . Now I know, that some of those proxies might be too slow, so i've set the timeout of the connection to 40000 milliseconds with conn.setConnectTimeout(40000) and conn.setReadTimeout(40000) . After doing so, i got this code: long diff = 0; long starttime = 0; long endtime = 0; try { starttime = System.currentTimeMillis(); conn.connect(); endtime = System.currentTimeMillis(); diff = endtime - starttime; if (endtime <= starttime + conn.getConnectTimeout()) { //Trying to
