You can use code like this

// Create a new HttpClient and Post Header
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(
                "http://fort.example.com");
        JSONObject json = new JSONObject();

        try {
            // Add your data
            json.put("key", "value");
            StringEntity se = new StringEntity( json.toString());
            httppost.setEntity(se);

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);

            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(
                            response.getEntity().getContent(), "UTF-8"));
            String jsonString = reader.readLine();
            JSONTokener tokener = new JSONTokener(jsonString);

            JSONObject finalResult = new JSONObject(tokener);

Don't forget to add this to nonUI thread.

How can I send JSON data to server, It is commonly used to send data from or to server. Nowadays it is widely used in API integration because of its advantages and simplicity. In this example we are  JavaScript Object Notation (JSON). It is a lightweight data transferring format. It is very easy to understand by human as well as machine. It is commonly used to send data from or to server. Nowadays it is widely used in API integration because of its advantages and simplicity.


You can use droidQuery to do this very easily:

$.ajax(new AjaxOptions().url("http://fort.example.com")
                        .type("POST")
                        .data("\"signup\": [{" +
                              "\"username\": \"test1264\"," +
                              "\"password\": \"1234\"," +
                              "\"email\": \"example@gmail.com\"," +
                              "\"phoneno\": \"223344556\"," +
                              "\"altphoneno\": \"12345678\"," +
                              "\"firstname\": \"abc\"," +
                              "\"lastname\": \"xyz\"" +
                        "\"}]")
                        .dataType("json")
                        .success(new Function() {
                            @Override
                            public void invoke($ d, Object... args) {
                                JSONObject json = (JSONObject) args[0];
                                boolean success = json.getBoolean("status");
                                if (success) {
                                    //handle success
                                }
                                else {
                                    //handle error
                                }
                            }
                        })
                        .error(new Function() {
                            @Override
                            public void invoke($ d, Object... args) {
                                AjaxError error = (AjaxError) args[0];
                                Log.i("Ajax", "Error " + error.status + ": " + error.reason);
                            }
                        }));

You can repeat this logic for other cases, such as your login web service.

How to send a JSON object to a server using Javascript , JavaScript can send network requests to the server and load JSON. JS does this using something called AJAX. AJAX stands for Asynchronous  Whenever we need data to process further, we request server to send data and the only format we mostly use is JSON (JavaScript Object Notation) a basic format that can easily being understand by most of the programming languages in web development. So, in this tutorial we are going to understand how to send data in JSON format through our server?


PostMethod method = new PostMethod();
org.apache.commons.httpclient.URI newUri = new org.apache.commons.httpclient.URI(URIstring, true);
method.setURI(newUri);
method.setRequestBody(JsonObj().toString());
method.setRequestHeader("Content-Type", "application/json");
org.apache.commons.httpclient.HttpClient newhttpClient = new org.apache.commons.httpclient.HttpClient();
int statusCode = newhttpClient.executeMethod(method);
return method.getResponseBodyAsString();

How to Send and Receive JSON Data to and from the Server, JSON stands for JavaScript Object Notation. It is an independent data exchange format and is the best alternative for XML. This chapter  I agree the data must be converted into a JSON string, not only to agree with the dataType and contentType setup but more importantly, to satisfy the server. data: JSON.stringify(data), dataType:'json'


How to send JSON data to server with http post request, In this tutorial, we'll demonstrate how to make a JSON POST request using the target URI string that accepts the JSON data via HTTP POST method: Failing to do so, the server returns HTTP status code “400-bad request”. Sending the JSON data inside the HTTP post request Once the JSON data is available as a String, the code calls http.POST to send out the HTTP request with POST as the request method. When the call returns, the status code of the HTTP response that the server returns back is stored in httpResponseCode.


For Restful API, can GET method use json data?, If you want to send JSON data from Android app to a server, how do you go about doing it. Follow the steps below to use Async thread to do it. I'm new to IOS development and I have started with the swift language. I'm trying to get the value from two text fields and convert those two text fields into json and send that json to the server receive.php.


Making a JSON POST Request With HttpURLConnection, Using XMLHttpRequest() in plain JavaScript XMLHttpRequest is an API that provides client functionality for transferring data between a client and a server. The common ways I encountered are using the Base64 string approach: you encode your image into a Base64 string and set it as part of the JSON Object that you send over to your server. Another approach seems to be using the Binary Data in JSON but I'd never tried this before so not much info from me.
