translating curl command into java/android

Question

Can someone help me figure out how to translate the following curl commands into Java syntax for use in an Android application?

The curl commands are:

curl -u username:password -H "Content-Type:application/vnd.org.snia.cdmi.container" http://localhost:8080/user

curl -u username:password -T /home/user1/a.jpg -H "Content-Type:image" http://localhost:8080/user/a.jpg

thanks

You can use Apache HttpClient in Android for performing HTTP posts.

• HttpClient code snippet (untested)

  public void postData(String url) {
      // Create a new HttpClient and Post Header
     HttpClient httpclient = new DefaultHttpClient();
     HttpPost httppost = new HttpPost(url);
  
  try {
      // Set the headers (your -H options)
      httpost.setHeader("Content-type", "application/json");
      // Add your data
      List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
      nameValuePairs.add(new BasicNameValuePair("param1", "value1"));
      httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
  
      // Execute HTTP Post Request
      HttpResponse response = httpclient.execute(httppost);
  
  } catch (Exception e) {
      // Exception handling
  } 
  

  }
