[java] Http Post With Body

i have sent method in objective-c of sending http post and in the body i put a string:

NSString *requestBody = [NSString stringWithFormat:@"mystring"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:[requestBody dataUsingEncoding:NSUTF8StringEncoding]];

now in Android i want to do the same thing and i am looking for a way to set the body of http post.

This question is related to java android

The answer is


 ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

then add elements for each pair

 nameValuePairs.add(new BasicNameValuePair("yourReqVar", Value);
 nameValuePairs.add( ..... );

Then use the HttpPost:

HttpPost httppost = new HttpPost(URL);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

and use the HttpClient and Response to get the response from the server


You can try something like this using HttpClient and HttpPost:

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("mystring", "value_of_my_string"));
// etc...

// Post data to the server
HttpPost httppost = new HttpPost("http://...");
httppost.setEntity(new UrlEncodedFormEntity(params));

HttpClient httpclient = new DefaultHttpClient();
HttpResponse httpResponse = httpclient.execute(httppost);

You can use HttpClient and HttpPost to send a json string as body:

public void post(String completeUrl, String body) {
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(completeUrl);
    httpPost.setHeader("Content-type", "application/json");
    try {
        StringEntity stringEntity = new StringEntity(body);
        httpPost.getRequestLine();
        httpPost.setEntity(stringEntity);

        httpClient.execute(httpPost);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

Json body example:

{
  "param1": "value 1",
  "param2": 123,
  "testStudentArray": [
    {
      "name": "Test Name 1",
      "gpa": 3.5
    },
    {
      "name": "Test Name 2",
      "gpa": 3.8
    }
  ]
}

You can use HttpClient and HttpPost to build and send the request.

HttpClient client= new DefaultHttpClient();
HttpPost request = new HttpPost("www.example.com");

List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("paramName", "paramValue"));

request.setEntity(new UrlEncodedFormEntity(pairs ));
HttpResponse resp = client.execute(request);
