Server returns JSON object in case of success and simple String for error case.
There are no problems with parsing JSON into object. The problem rises when I want to parse error since the response.errorBody().string() is empty.
When I send the same request using Postman the response as follows:
And I can't read this error... Anyone faced such problem?

My answer is based on HttpLoggingInterceptor class.
I wrote getStatusError() method by given in parameter response.errorBody().
private StatusError getStatusError(ResponseBody responseBody) {
StatusError statusError = null;
if (responseBody != null) {
try {
BufferedSource source = responseBody.source();
if (source != null) {
source.request(Long.MAX_VALUE); // Buffer the entire body.
Buffer buffer = source.buffer();
Charset charset = UTF8;
MediaType contentType = responseBody.contentType();
if (contentType != null) {
charset = contentType.charset(UTF8);
}
String string = buffer.clone().readString(charset);
if (!TextUtils.isEmpty(string)) {
GsonBuilder gsonBuilder = new GsonBuilder();
Gson gson = gsonBuilder.create();
statusError = gson.fromJson(string, StatusError.class);
}
}
} catch (Exception e) {
LogUtils.LOGW(TAG, "Impossible to get StatusError stream", e);
}
}
return statusError;
}
StatusError is a POJO class to map (JSON) elements:
public class StatusError {
#SerializedName("message")
public String message;
#SerializedName("errors")
public ArrayList<ErrorDetail> errors;
}

I am hitting a URL with four parameters, If parameters not match I will get the Following response.
This is my JSON response:
{
"result": "0"
}
Now my question is. How do I get that result value from response?
Here's, my Retrofit instance
public class RetrofitClientInstance {
private static Retrofit retrofit;
private static final String BASE_URL = "https://URL/";
public static Retrofit getRetrofitInstance() {
if (retrofit == null) {
retrofit = new retrofit2.Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}
}
Retrofit Interface
public interface ApiInterface {
#GET("f/f/ff.php")
Call<Object> verifyUser (#QueryMap Map< String, String > params );
}
Code for getting the response
ApiInterface apiInterface = RetrofitClientInstance.getRetrofitInstance().create(ApiInterface.class);
Call<Object> call = apiInterface.verifyUser(params);
call.enqueue(new Callback<Object>() {
#Override
public void onResponse(Call<Object> call, Response<Object> response) {
Log.e("Code ", response.code() + "");
if (!response.isSuccessful()) {
Log.e("Code ", response.code() + "");
return;
}
// Convert String to json object
JSONObject json = null;
String str_value = null;
try {
json = new JSONObject(String.valueOf(response));
//JSONObject json_LL = json.getJSONObject("result");
// get value from LL Json Object
str_value = json.getString("result"); //<< get value here
} catch (JSONException e) {
e.printStackTrace();
}
// Log.e("Response ", json.length() + "");
Toast.makeText(RegistrationForm.this, str_value, Toast.LENGTH_SHORT).show();
Object responseBody = response.body();
}
#Override
public void onFailure(Call<Object> call, Throwable t) {
Log.e("Failed", t.getMessage() + "");
}
});
Since you're using Gson. You can replace Object with a class that holds the fields that you want to parse.
for example:
public class ResultResponse {
String result;
public String getResult() {
return result;
}
public void setResult(String result) {
this.result = result;
}
}
And change your endpoint method to return this class.
public interface ApiInterface {
#GET("f/f/ff.php")
Call< ResultResponse> verifyUser (#QueryMap Map< String, String > params );
}
Also don't forget to change the remaining code to use the new return type ResultResponse
Call<ResultResponse> call = apiInterface.verifyUser(params);
call.enqueue(new Callback<ResultResponse>() {
#Override
public void onResponse(Call<ResultResponse> call, Response<ResultResponse> response) {
Log.e("Code ", response.code() + "");
if (!response.isSuccessful()) {
Log.e("Code ", response.code() + "");
return;
}
ResultResponse resultResponse = response.body();
String str_value = resultResponse.getResult();
Toast.makeText(RegistrationForm.this, str_value, Toast.LENGTH_SHORT).show();
}
#Override
public void onFailure(Call<Object> call, Throwable t) {
Log.e("Failed", t.getMessage() + "");
}
});

API client
Please help
//In ApiInterface do like this
#Headers("charset:UTF-8")
#POST("verificationProfiles")
Call<BaseModel> SearchResponse(

have you tried #SerializedName("") and #Expose in your pojo class
#SerializedName("status")
#Expose
private Boolean status;
Instead of JSONObject, you can use Map
For example:
Headers("Content-Type: application/json")
#POST("/apipath")
request(#Body Map<String, String> body);
Im using retrofit to send a a json object to the server, im trying to create a user, im sending this json object
{"apellido":"prueba","email":"prueba#hotmail.com","fechaDeNacimiento":"11/29/1998","formaDeRegistro":"Android","nombre":"prueba","password":"12345678","username":"prueba"}
In this example i create a invalid user , so the server response with a json object where code its the code error and message its the explication of the error
[{"code":"5","message":"The email is in use"}]
Interface
public interface UserClient {
#POST("usuarios")
Call<Usuarios> create(#Body Usuarios usuario);
}
Data model
import com.google.gson.annotations.SerializedName;
public class Usuarios {
#SerializedName("username")
String username;
#SerializedName("email")
String email;
#SerializedName("password")
String password;
#SerializedName("nombre")
String nombre;
#SerializedName("apellido")
String apellido;
#SerializedName("fechaDeNacimiento")
String fechaDeNacimiento;
#SerializedName("formaDeRegistro")
String formaDeRegistro;
String message;
public Usuarios(String email, String username, String password, String nombre, String apellido, String fechaDeNacimiento, String formaDeRegistro){
this.username=username;
this.email=email;
this.password=password;
this.nombre = nombre;
this.apellido= apellido;
this.fechaDeNacimiento = fechaDeNacimiento;
this.formaDeRegistro = formaDeRegistro;
}
public String getMessage(){
return message;
}
}
and Retrofit implement
OkHttpClient.Builder okhttpClientBuilder=new OkHttpClient.Builder();
HttpLoggingInterceptor loggin=new HttpLoggingInterceptor();
loggin.setLevel(HttpLoggingInterceptor.Level.BODY);
okhttpClientBuilder.addInterceptor(loggin);
Retrofit.Builder builder = new Retrofit.Builder()
.baseUrl("https://intense-lake-39874.herokuapp.com")
.addConverterFactory(GsonConverterFactory.create())
.client(okhttpClientBuilder.build());
Retrofit retrofit = builder.build();
UserClient service = retrofit.create(UserClient.class);
Call<Usuarios> call = service.create(usuario);
call.enqueue(new Callback<Usuarios>() {
#Override
public void onResponse(Call<Usuarios> call, Response<Usuarios> response) {
Toast.makeText(Main2Activity.this,"Usuario Registrado! "+response.body().getMessage,Toast.LENGTH_SHORT).show();
}
#Override
public void onFailure(Call<Usuarios> call, Throwable t) {
Toast.makeText(Main2Activity.this,"Algo fallo..",Toast.LENGTH_SHORT).show();
}
});
}
So i can see the logcat response but in the body its appoint to null, how i can acces to the "message"?
This is the logcat
That error is because your response is not successful therefore you need to parse the error body, try with this code:
if (response.isSuccessful()) {
// Do your success stuff...
} else
{
try
{
JSONObject jObjError = new JSONObject(response.errorBody().string());
Toast.makeText(getContext(), jObjError.getString("message"), Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(getContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
}
Of course that you can use another parser like Gson .

Just use annotation:
public interface Service {
#Headers("application-Key", your key)
#GET("/example")
Call<List<Example>> getExamples();
}
All examples are available here: https://futurestud.io/tutorials/retrofit-add-custom-request-header
You can use #Header annotation for your api method as it is clearly stated in a documentation https://square.github.io/retrofit/
#Headers("XYZ: value")
you can set it in your base retrofit file
request = original.newBuilder()
.header("header key", "your header)
.header("x-requested-with", "XMLHttpRequest")
.method(original.method(), original.body())
.build();
okhttp3.Response response = chain.proceed(request);
#Header
this is a Retrofit specific annotation which will allow you the pass the request headers to the targeting HTTP endpoint, where every argument represents a request header entry.
I create a request with retrofit2 and send parameter to server, how can access sent parameter in onResponse?
retrofit = new Retrofit.Builder()
.baseUrl("baseAddress")
.addConverterFactory(GsonConverterFactory.create())
.build();
ApiBase serviceSetParam = retrofit.create(ApiBase.class);
Call<String> myCall = serviceSetParam.setParam("data1","data2");
Callback<String> myCallback = new Callback<String>() {
#Override
public void onResponse(Call<String> call, Response<String> response) {
//i need access data1 & data2 Here !
if (response.isSuccessful()) {
String mResponse= response.body();
} else {
Utils.Log("unSuccessful");
}
}
#Override
public void onFailure(Call<String> call, Throwable t) {
Utils.Log("onFailure");
}
};
myCall.enqueue(myCallback);
here the send param method:
#FormUrlEncoded
#POST("set")
Call<String> setParam(#Field("param1") String param1, #Field("param2") String param2);
in onResponse method of your request, test this code:
try {
BufferedSink bf = new Buffer();
call.request().body().writeTo(bf);
Log.i("params are",bf.buffer().readUtf8().toString());
} catch (IOException e) {
e.printStackTrace();
}
You need to get the original Request from OkHttp.
List<String> pathSegments = original(response.raw()).url().pathSegments();
given:
static Request original(Response response) {
while (true) {
Response prior = response.priorResponse();
if (prior == null) {
break;
}
response = prior;
}
return response.request();
}
