Retrofit2: Sending Post Request With String Request

Hi I am new to android and now I am using Retrofit for integrating the web services. I am not understanding how to send parameters to the server using Retrofit POST request. Please

Solution 1:

Make a new model class :

publicclassCredentials {
    privateString email;
    privateString password;
    publicCredentials(String email, String password) {
        this.email = email;
        this.password = password;
    }
}

Then modify your interface :

publicinterfacePostInterface {

    @POST("User/DoctorLogin")
    Call<String> getStringScalar(@Body Credentials body);
}

Then call it like this :

service.getStringScalar(newCredentials("device3@gmail.com", "1234")).enqueue(newCallback<String>() {
        @OverridepublicvoidonResponse(Call<String> call, Response<String> response) {

            System.out.println("result is====>" + response.body());
        }

        @OverridepublicvoidonFailure(Call<String> call, Throwable t) {
            System.out.println("Failuere");
        }
    });

Solution 2:

publicinterfacePostInterface {

@POST("User/DoctorLogin")
Call<JsonObject> getStringScalar(@Field("PARAMATER_ID") String body);}

You can use string also in place of jsonobject,but i would recomment using json. "@Field(YOUR_PARAMETER)" is the way you use this

Solution 3:

Read this artical this will help you to understand retrofit.

Solution 4:

create a model class

publicclassModel{

String userName;
String password;

}

generate getter and setter

modify your interface

publicinterfaceApiInterface {
@FormUrlEncoded@POST("User/DoctorLogin")
Call<Model> loadDetail(@Field("user_id") String user_id,
                       @Field("password") String password);
}

and call it like this

Retrofitretrofit=newRetrofit.Builder()
                .addConverterFactory(GsonConverterFactory.create()).baseUrl(url)
            .build();

    ApiInterfaceservice= retrofit.create(ApiInterface.class);

    Call<Model> call = service.loadDetail("username", "password");
    call.enqueue(newCallback<Model>() {
        @OverridepublicvoidonResponse(Call<Model> call, Response<Model> response) {

            intstatusCode= response.code();
            Modeluser= response.body();

            Log.d("userName: "  user.getUserName());
           Log.d("password: " + user.getPassword());
        }

        @OverridepublicvoidonFailure(Call<Model> call, Throwable t) {
            Toast.makeText(getApplicationContext(), "data not found", Toast.LENGTH_SHORT).show();
        }
