Setting parameters in HTTP POST

Question

I am trying make a JSON call to a server using HttpClient API. The code sinppet is shown below.

HttpClient httpClient = new DefaultHttpClient();
HttpGet httpPost = new HttpPost(URLString);
HttpResponse response = httpClient.execute(httpPost);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);  
nameValuePairs.add(new BasicNameValuePair("method", "completeUserLogin")); 
String[] params = new String[]{"100408"};
response = httpClient.execute(httpPost);

I want to add params to nameValuePairs. BasicNameValuePair class does not allow you to add arrays. Any thoughts?

Thanks in advance!

you should try converting your array to the string representation expected by the post, and then adding it. — CasualT

Look at this . Here they pass the array in BasicNameValuePairs.Here the colours is the array which we are going to send on a server. You should use your array varible instead of colours.

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();  
nameValuePairs.add(new BasicNameValuePair("colours[0]","red"));  
nameValuePairs.add(new BasicNameValuePair("colours[1]","white"));  
nameValuePairs.add(new BasicNameValuePair("colours[2]","black"));  
nameValuePairs.add(new BasicNameValuePair("colours[3]","brown"));  

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
response = httpClient.execute(httpPost);

If you are posting data in json format then you should not post params like this. Instead create a JSONObject put these values in that json object, and get a string from that json object and then create a StringEntity, and set this Entity to HttpPost object.

Creating JSONObject for the Request:

JSONObject json=new JSONObject();
json.put("method", "completeUserLogin");
JSONArray arr= new JSONArray();
arr.put("100408");
json.put("params", arr);

String params=json.toString();
