JSONP and it’s usages

JSONP or “JSON with padding” is a communication technique used in JavaScript programs running in web browsers to request data from a server in a different domain, something prohibited by typical web browsers because of the same-origin policy. Wikipedia

Simple HTTP Request in Android

New Post has been published on http://droidstack.com/32/simple-http-request-in-android/

Simple HTTP Request in Android

In most of the android applications it is essential that app may need to connect to internet and make some HTTP requests. In this article i’ll be demonstrating about making simple HTTP Requests in android or java.

Creating HTTP Client and HTTP Post

// Creating HTTP client HttpClient httpClient = new DefaultHttpClient(); // Creating HTTP Post HttpPost httpPost = new HttpPost("http://www.droidstack.com/login");

Bulding Post Parameters The following code will create post parameters pair with key and value.

// Building post parameters, key and value pair List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2); nameValuePair.add(new BasicNameValuePair("email", "[email protected]")); nameValuePair.add(new BasicNameValuePair("password", "123456"));

URL Encoding POST data Before making HTTP request you need to encode the post data in order to convert all string data into valid url format.

// Url Encoding the POST parameters try httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair)); catch (UnsupportedEncodingException e) // writing error to Log e.printStackTrace();

Finally making HTTP Request Finally you need to execute httpPost using the httpClient created before.

// Making HTTP Request try HttpResponse response = httpClient.execute(httpPost); // writing response to log Log.d("Http Response:", response.toString()); catch (ClientProtocolException e) // writing exception to log e.printStackTrace(); catch (IOException e) // writing exception to log e.printStackTrace();

Final Code The following is the final code to make http Requests. I am writing response to log. Check your Log report in Eclipse to see your http response.

package com.droidstack.httprequests; import java.io.IOException; import java.io.UnsupportedEncodingException; import java.util.ArrayList; import java.util.List; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.ClientProtocolException; import org.apache.http.client.HttpClient; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.message.BasicNameValuePair; import android.app.Activity; import android.os.Bundle; import android.util.Log; public class AndroidHTTPRequestsActivity extends Activity @Override public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.main); // Creating HTTP client HttpClient httpClient = new DefaultHttpClient(); // Creating HTTP Post HttpPost httpPost = new HttpPost( "http://www.droidstack.com/login"); // Building post parameters // key and value pair List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2); nameValuePair.add(new BasicNameValuePair("email", "[email protected]")); nameValuePair.add(new BasicNameValuePair("password", "123456")); // Url Encoding the POST parameters try httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair)); catch (UnsupportedEncodingException e) // writing error to Log e.printStackTrace(); // Making HTTP Request try HttpResponse response = httpClient.execute(httpPost); // writing response to log Log.d("Http Response:", response.toString()); catch (ClientProtocolException e) // writing exception to log e.printStackTrace(); catch (IOException e) // writing exception to log e.printStackTrace();
