In this blog post, you can learn android source code on how to post data to a url by using a httpclient post method.
Please find below the very simple android source code example for dealing with httpclient post. This simple code executes a http post request with org.apache.http.client.HttpClient and can be used in the combination with Non-Blocking Web Requests.
public void postData() {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.website.com/phpscript.php");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("id", "9449"));
nameValuePairs.add(new BasicNameValuePair("stringdata", "android"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}
Creating HTTP Client and HTTP Post
// Creating a HTTP client
HttpClient httpClient = new DefaultHttpClient();
// Creating a HTTP Post
HttpPost httpPost = new HttpPost("http://www.androidsourcecodeexamples.com/index");
Create post parameters with key and value.
List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);
nameValuePair.add(new BasicNameValuePair("email", "xxx@gmail.com"));
nameValuePair.add(new BasicNameValuePair("password", "xxx_password"));
At last we should execute the httpPost using httpClient which is created previously.
// 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();
}
Please find below the full android code units to make a http Request. This example is for response to the log. For http response see your eclipse log report.
