Send Post Request With Params Using Retrofit

March 21, 2024 Post a Comment

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 1:

build.gradle

compile'com.google.code.gson:gson:2.6.2'compile'com.squareup.retrofit2:retrofit:2.1.0'// compulsory

      compile'com.squareup.retrofit2:converter-gson:2.1.0' //for retrofit conversion

Login APi Put Two Parameters

{"UserId":"1234","Password":"1234"}

Login Response

{"UserId":"1234","FirstName":"Keshav","LastName":"Gera","ProfilePicture":"312.113.221.1/GEOMVCAPI/Files/1.500534651736E12p.jpg"}

APIClient.java

import retrofit2.Retrofit;
    import retrofit2.converter.gson.GsonConverterFactory;

    classAPIClient {

        publicstaticfinalStringBASE_URL="Your Base Url ";
        privatestaticRetrofitretrofit=null;

        publicstatic Retrofit getClient() {
            if (retrofit == null) {
                retrofit = newRetrofit.Builder()
                        .baseUrl(BASE_URL)
                        .addConverterFactory(GsonConverterFactory.create())
                        .build();
            }
            return retrofit;
        }
    }

APIInterface interface

interfaceAPIInterface {

        @POST("LoginController/Login")
        Call<LoginResponse> createUser(@Body LoginResponse login);
    }

Login Pojo

    package pojos;

    import com.google.gson.annotations.SerializedName;

    publicclassLoginResponse {


        @SerializedName("UserId")
        publicStringUserId;
        @SerializedName("FirstName")
        publicStringFirstName;
        @SerializedName("LastName")
        publicStringLastName;
        @SerializedName("ProfilePicture")
        publicStringProfilePicture;
        @SerializedName("Password")
        publicStringPassword;
        @SerializedName("ResponseCode")
        publicStringResponseCode;
        @SerializedName("ResponseMessage")
        publicStringResponseMessage;

        publicLoginResponse(StringUserId, StringPassword) {
            this.UserId = UserId;
            this.Password = Password;
        }

        publicStringgetUserId() {
            returnUserId;
        }

        publicStringgetFirstName() {
            returnFirstName;
        }

        publicStringgetLastName() {
            returnLastName;
        }

        publicStringgetProfilePicture() {
            returnProfilePicture;
        }

        publicStringgetResponseCode() {
            returnResponseCode;
        }

        publicStringgetResponseMessage() {
            returnResponseMessage;
        }
    }

Solution 2:

This is a simple solution where we do not need to use JSON

publicinterfaceRegisterAPI {
@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

privatevoidinsertUser(){
    //Here we will handle the http request to insert user to mysql db//Creating a RestAdapterRestAdapteradapter=newRestAdapter.Builder()
            .setEndpoint(ROOT_URL) //Setting the Root URL
            .build(); //Finally building the adapter//Creating object for our interfaceRegisterAPIapi= 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 callbacknewCallback<Response>() {
                @Overridepublicvoidsuccess(Response result, Response response) {
                    //On success we will read the server's output using bufferedreader//Creating a bufferedreader objectBufferedReaderreader=null;

                    //An string to store output from the serverStringoutput="";

                    try {
                        //Initializing buffered reader
                        reader = newBufferedReader(newInputStreamReader(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();
                }

                @Overridepublicvoidfailure(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.

publicclassLandingPageReport{

    private ArrayList<LandingPageReportItem> GetDetailWithMonthWithCodeResult;

    // + Getter Setter methods
}

publicclassLandingPageReportItem{

    privateString code;

    privateString 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

publicinterfaceService {
    @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.

publicinterfaceAPIInterface {
    @POST("/GetDetailWithMonthWithCode")
    List<LandingPageReport> getLandingPageReport(@Body Report report);
}

Then make your POJO with a constructor, getters and setters.

publicstaticclassReport {
    privateString code;
    privateString monthact;

    publicReport(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));
