httpurlconnection

I want to make some API calls to a server using HttpURLConnection . But the requests are not successful, returning: <error> <http_status>400 Bad Request</http_status> <message>Unexpected request Content-Type header ''. Expecting 'application/x-www-form-urlencoded'.</message> </error> So I want to check what the "real" content is that is being sent to the server. By real content I mean the exact HTTP request. Any ideas how I can see this? Edit: Based on the first answers here I should clarify my problem: I want to avoid using an external program like HTTP sniffer or anything and I was hoping

I am encountering some problems with the HttpUrlConnection in devices running Jellybean (4.1 - 4.3) wherein connections are not closed and results to a SocketException "Too many open files" after executing a number of times. I do call HttpUrlConnection.disconnect() and am closing all the Inputstream, Outputstream, Reader and Writers in a finally block. Going to adb shell and executing a netstat shows all the connections created by the application are left in CLOSE_WAIT state. InputStream inputStream = httpUrlConnection.getInputStream(); // After calling inputStream.read() then the problem

I'm using URL.openConnection() to download something from a server. The server says Content-Type: text/plain; charset=utf-8 But connection.getContentEncoding() returns null . What up? Waldheinz This is documented behaviour as the getContentEncoding() method is specified to return the contents of the Content-Encoding HTTP header, which is not set in your example. You could use the getContentType() method and parse the resulting String on your own, or possibly go for a more advanced HTTP client library like the one from Apache .

Hi I am trying to use the HttpResponseCache introduced in Android 4.The docs do talk clearly about how to install the cache but I am at a complete loss on how to cache Images downloaded from the net.Earlier I was using the DiskLruCache to cache them. Would anyone point me towards some examples of working code where HttpResponseCache has been used.. Edit:- Can someone tell me what I am doing wrong here:- MainActivity.java public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final long httpCacheSize = 10 * 1024 * 1024; //

I make some proxy server in andorid which modify http headers, it works ok, but I have to forward full response to 'top layer'. How I can read whole response (all headers, content, everything) from HttpURLConnection? HttpURLConnection httpURLConnection; URL url = new URL(ADDRESS); httpURLConnection = (HttpURLConnection) url.openConnection(); // add headers, write output stream, flush if (httpURLConnection.getResponseCode() == HttpsURLConnection.HTTP_OK) { Map<String, List<String>> map = httpURLConnection.getHeaderFields(); System.out.println("Printing Response Header...\n"); for (Map.Entry

I've already created my HTTPUrlConnection : String postData = "x=val1&y=val2"; URL url = new URL(strURL); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setRequestMethod("POST"); conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); conn.setRequestProperty("Set-Cookie", sessionCookie); conn.setRequestProperty("Content-Length", "" + Integer.toString(postData.getBytes().length)); // How to add postData as http body? conn.setUseCaches(false); conn.setDoInput(true); conn.setDoOutput(true); I don't know how to set postData in http body. How to do so?

We have an Android application that requires the user to enter an answer to a Captcha. The Captcha is generated on our server. When the replies, it is sent to the server for verifying. Problem is that since I have to close the HttpURLConnection after the request for the Captcha I then find that the reply is running on a different session on the sever. Because of this the Captcha check fails since it is session dependant. Is there a way to keep the connection alive or should I be following a different path? I know that in the equivalent iPhone application they remain "connected" and thus have

I have a Java application (JDK 1.7.0_13) and am using java.net.HttpURLConnection to connect to some servlet based services that do session management. I am trying to figure out how to use java.net.CookieManager to track session cookies. Reading the docs I get the impression that installing CookieManager with CookieHandler.setDefault(new CookieManager()) should cause cookie management to happen automatically. However, multiple requests to the same URL's does not seem to preserve cookies. Do I have to manually extract cookies from responses and resend them in requests on my own or is
