How to use OKHTTP to make a post request?

Question

I read some examples which are posting jsons to the server.

some one says :

OkHttp is an implementation of the HttpUrlConnection interface p

Answer 1

Here is my method to do post request first pass in method map and data like

HashMap<String, String> param = new HashMap<String, String>();

param.put("Name", name);
param.put("Email", email);
param.put("Password", password);
param.put("Img_Name", "");

final JSONObject result = doPostRequest(map,Url);

public static JSONObject doPostRequest(HashMap<String, String> data, String url) {

    try {
        RequestBody requestBody;
        MultipartBuilder mBuilder = new MultipartBuilder().type(MultipartBuilder.FORM);

        if (data != null) {


            for (String key : data.keySet()) {
                String value = data.get(key);
                Utility.printLog("Key Values", key + "-----------------" + value);

                mBuilder.addFormDataPart(key, value);

            }
        } else {
            mBuilder.addFormDataPart("temp", "temp");
        }
        requestBody = mBuilder.build();


        Request request = new Request.Builder()
                .url(url)
                .post(requestBody)
                .build();

        OkHttpClient client = new OkHttpClient();
        Response response = client.newCall(request).execute();
        String responseBody = response.body().string();
        Utility.printLog("URL", url);
        Utility.printLog("Response", responseBody);
        return new JSONObject(responseBody);

    } catch (UnknownHostException | UnsupportedEncodingException e) {

        JSONObject jsonObject=new JSONObject();

        try {
            jsonObject.put("status","false");
            jsonObject.put("message",e.getLocalizedMessage());
        } catch (JSONException e1) {
            e1.printStackTrace();
        }
        Log.e(TAG, "Error: " + e.getLocalizedMessage());
    } catch (Exception e) {
        e.printStackTrace();
        JSONObject jsonObject=new JSONObject();

        try {
            jsonObject.put("status","false");
            jsonObject.put("message",e.getLocalizedMessage());
        } catch (JSONException e1) {
            e1.printStackTrace();
        }
        Log.e(TAG, "Other Error: " + e.getLocalizedMessage());
    }
    return null;
}

Answer 2

This is one of the possible solutions to implementing an OKHTTP post request without a request body.

RequestBody reqbody = RequestBody.create(null, new byte[0]);  
Request.Builder formBody = new Request.Builder().url(url).method("POST",reqbody).header("Content-Length", "0");
clientOk.newCall(formBody.build()).enqueue(OkHttpCallBack());

Answer 3

You can make it like this:

    MediaType JSON = MediaType.parse("application/json; charset=utf-8");
    RequestBody body = RequestBody.create(JSON, "{"jsonExample":"value"}");

    OkHttpClient client = new OkHttpClient();

    Request request = new Request.Builder()
            .url(url)
            .post(body)
            .addHeader("Authorization", "header value") //Notice this request has header if you don't need to send a header just erase this part
            .build();

    Call call = client.newCall(request);

    call.enqueue(new Callback() {
        @Override
        public void onFailure(Request request, IOException e) {

            Log.e("HttpService", "onFailure() Request was: " + request);

            e.printStackTrace();
        }

        @Override
        public void onResponse(Response r) throws IOException {

            response = r.body().string();

            Log.e("response ", "onResponse(): " + response );

        }
    });

OkHttp POST request with token in header

       RequestBody requestBody = new MultipartBody.Builder()
            .setType(MultipartBody.FORM)
            .addFormDataPart("search", "a")
            .addFormDataPart("model", "1")
            .addFormDataPart("in", "1")
            .addFormDataPart("id", "1")
            .build();
    OkHttpClient client = new OkHttpClient();
    okhttp3.Request request = new okhttp3.Request.Builder()
            .url("https://somedomain.com/api")
            .post(requestBody)
            .addHeader("token", "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiIkMnkkMTAkZzZrLkwySlFCZlBmN1RTb3g3bmNpTzltcVwvemRVN2JtVC42SXN0SFZtbzZHNlFNSkZRWWRlIiwic3ViIjo0NSwiaWF0IjoxNTUwODk4NDc0LCJleHAiOjE1NTM0OTA0NzR9.tefIaPzefLftE7q0yKI8O87XXATwowEUk_XkAOOQzfw")
            .addHeader("cache-control", "no-cache")
            .addHeader("Postman-Token", "7e231ef9-5236-40d1-a28f-e5986f936877")
            .build();

    client.newCall(request).enqueue(new Callback() {
        @Override
        public void onFailure(Call call, IOException e) {
            e.printStackTrace();
        }

        @Override
        public void onResponse(Call call, okhttp3.Response response) throws IOException {
            if (response.isSuccessful()) {
                final String myResponse = response.body().string();

                MainActivity.this.runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Log.d("response", myResponse);
                        progress.hide();
                    }
                });
            }
        }
    });

1. Add the following to the build.gradle
   

compile 'com.squareup.okhttp3:okhttp:3.7.0'

2. Create a new thread, in the new thread add the following code.

OkHttpClient client = new OkHttpClient();
MediaType MIMEType= MediaType.parse("application/json; charset=utf-8");
RequestBody requestBody = RequestBody.create (MIMEType,"{}");
Request request = new Request.Builder().url(url).post(requestBody).build();
Response response = client.newCall(request).execute();
