Send Post Request With Params Using Retrofit
I'm trying unsuccessfully to consume an API on Android using Retrofit library but while using POSTMAN I can see the expected results. POSTMAN SETTING The api url (base+controller

Solution 2:
This is a simple solution where we do not need to use JSON
public interface RegisterAPI {
@FormUrlEncoded
@POST("/RetrofitExample/insert.php")
public void insertUser(
@Field("name") String name,
@Field("username") String username,
@Field("password") String password,
@Field("email") String email,
Callback<Response> callback);
}
method to send data
private void insertUser(){
//Here we will handle the http request to insert user to mysql db
//Creating a RestAdapter
RestAdapter adapter = new RestAdapter.Builder()
.setEndpoint(ROOT_URL) //Setting the Root URL
.build(); //Finally building the adapter
//Creating object for our interface
RegisterAPI api = adapter.create(RegisterAPI.class);
//Defining the method insertuser of our interface
api.insertUser(
//Passing the values by getting it from editTexts
editTextName.getText().toString(),
editTextUsername.getText().toString(),
editTextPassword.getText().toString(),
editTextEmail.getText().toString(),
//Creating an anonymous callback
new Callback<Response>() {
@Override
public void success(Response result, Response response) {
//On success we will read the server's output using bufferedreader
//Creating a bufferedreader object
BufferedReader reader = null;
//An string to store output from the server
String output = "";
try {
//Initializing buffered reader
reader = new BufferedReader(new InputStreamReader(result.getBody().in()));
//Reading the output in the string
output = reader.readLine();
} catch (IOException e) {
e.printStackTrace();
}
//Displaying the output as a toast
Toast.makeText(MainActivity.this, output, Toast.LENGTH_LONG).show();
}
@Override
public void failure(RetrofitError error) {
//If any error occured displaying the error as toast
Toast.makeText(MainActivity.this, error.toString(),Toast.LENGTH_LONG).show();
}
}
);
}
Now we can get the post request using php aur any other server side scripting.

Solution 3:
I have found the solution. The issue was a problem in my classes structure. So i updated them like the following samples.
public class LandingPageReport {
private ArrayList<LandingPageReportItem> GetDetailWithMonthWithCodeResult;
// + Getter Setter methods
}
public class LandingPageReportItem {
private String code;
private String field1;
// + Getter Setter methods
}
And then i use this retrofit configuration
@POST("/GetDetailWithMonthWithCode")
void getLandingPageReport(@Field("code") String code,
@Field("monthact") String monthact,
Callback<LandingPageReport> cb);
Solution 4:
You should create an interface for that like it is working well
public interface Service {
@FormUrlEncoded
@POST("v1/EmergencyRequirement.php/?op=addPatient")
Call<Result> addPerson(@Field("BloodGroup") String bloodgroup,
@Field("Address") String Address,
@Field("City") String city, @Field("ContactNumber") String contactnumber,
@Field("PatientName") String name,
@Field("Time") String Time, @Field("DonatedBy") String donar);
}
or you can visit to http://teachmeandroidhub.blogspot.com/2018/08/post-data-using-retrofit-in-android.html
and youcan vist to https://github.com/rajkumu12/GetandPostUsingRatrofit
Solution 5:
The good way in my opinion is to send it in the POST Body this means you'll have a create a new POJO but some might like this implementation the most.
public interface APIInterface {
@POST("/GetDetailWithMonthWithCode")
List<LandingPageReport> getLandingPageReport(@Body Report report);
}
Then make your POJO with a constructor, getters and setters.
public static class Report {
private String code;
private String monthact;
public Report(String code, String monthact) {
this.code = code;
this.monthact = monthact;
}
// Getters and Setters...
}
And just call it the normal way.
Call<List<Report>> request = apiInterface
.createRetrofitAPIInterface()
.getLandingPageReport(new Report(code, monthact));
