How to send JSON data as body in POST request through HttpClient - mysql

Question

I've a requirement. I have a working POST call ("http://localhost:8080/POSTAPI/table/testmaster/create"). I sent JSON data through postman and details got inserted into MySQL database. Now i'm trying to send the json data through apache httpcleint. but, it failed to insert into mysql database.
CloseableHttpClient client = HttpClients.createDefault();
HttpPost post = new HttpPost("http://localhost:8080/POSTAPI/table/testmaster/create");
JSONObject testmaster = new JSONObject();
testmaster.put("testRunId", testRunId);
testmaster.put("testClassName", className);
testmaster.put("testMethod", methodName);
testmaster.put("createdBy", "leela");
testmaster.put("createdDate", startDate);
testmaster.put("lastUpdatedBy", "raghu");
testmaster.put("lastUpdatedDate", endDate);
testmaster.put("attribute1", "methodName");
testmaster.put("attribute1Value",methodName );
testmaster.put("attribute2", "result");
testmaster.put("attribute2Value", successResult);
testmaster.put("attribute3", "Test Suite");
testmaster.put("attribute3Value", suiteName);
testmaster.put("attribute4", "test group");
testmaster.put("attribute4Value", TestGroup);
testmaster.put("attribute5", "dataprovider");
testmaster.put("attribute5Value", dataProvider);
StringEntity stringEntity = new StringEntity(testmaster.toString());
post.setEntity(stringEntity);
post.setHeader("Accept", "application/json");
post.setHeader("Content-type", "application/json");
CloseableHttpResponse response = client.execute(post);
System.out.println("Status: "+response.getStatusLine());
This is what i tried. if anybody have any idea of post operation through httpclient or any other alternative please let me know. Thanks in advance.

Use the following code :
private class postJsonData extends AsyncTask<Void, Integer, Boolean> {
ProgressDialog dialog;
String responseString = null;
private postJsonData() {
super();
dialog = new ProgressDialog(MainActivity.this);
this.dialog.setTitle("Please wait.");
this.dialog.setCancelable(false);
this.dialog.show();
}
#Override
protected void onPreExecute() {
dialog.setProgress(0);
super.onPreExecute();
}
#Override
protected void onProgressUpdate(Integer... progress) {
// Making progress bar visible
if (this.dialog.isShowing()) {
dialog.setProgress(progress[0]);
}
}
#SuppressWarnings("deprecation")
#Override
protected Boolean doInBackground(Void... params) {
Boolean result=false;
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://192.168.2.2/android/jsonpost.php");
try {
JSONObject testmaster = new JSONObject();
try {
testmaster.put("testRunId", "1");
testmaster.put("testClassName", "className");
testmaster.put("testMethod", "methodName");
testmaster.put("createdBy", "leela");
testmaster.put("createdDate", "startDate");
} catch (JSONException e) {
e.printStackTrace();
}
List<NameValuePair> nameValuePairs = new ArrayList<>();
nameValuePairs.add(new BasicNameValuePair("json_string", testmaster.toString()));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Making server call
HttpResponse response = httpclient.execute(httppost);
HttpEntity r_entity = response.getEntity();
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == 200) {
// Server response
responseString = EntityUtils.toString(r_entity);
result = false;
} else {
responseString = "Error occurred! Http Status Code: "
+ statusCode;
result = false;
}
} catch (final ClientProtocolException e) {
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(),
"ClientProtocolException : " + e.toString(),
Toast.LENGTH_LONG)
.show();
}
});
result = false;
} catch (final IOException e) {
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(),
"IOException : " + e.toString(),
Toast.LENGTH_LONG)
.show();
}
});
result = false;
}
return result;
}
#Override
protected void onPostExecute(final Boolean success) {
//progressBar.setVisibility(View.GONE);
if (dialog.isShowing()){
dialog.dismiss();
}
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(),
"Response from Server: " + responseString ,
Toast.LENGTH_LONG)
.show();
}
});
if (success){
}else{
}
super.onPostExecute(success);
}
}
Here is my php code which accepts the json string and decode into array.
<?php
if (empty($_POST['json_string'])) {
echo "Empty json data";
exit;
}else{
$json_string = $_POST['json_string'];
}
$params = array();
$params = json_decode($json_string,true);
//echo $params['testClassName'];
var_dump($params);
?>
