Get raw HTTP response with Retrofit

Question

I want to get the raw http response from my API REST. I have tried with this interface:

@POST("/login") @FormUrlEncoded Call<retrofit.Response> login(@Field("username") String login, @Field("password") String pass,                      @Field("appName") String appName, @Field("appKey") String appKey); 

But I get:

java.lang.IllegalArgumentException: Unable to create call adapter for retrofit.Call for method Api.login

I create Retrofit this way:

Retrofit.Builder retrofitBuilder = new Retrofit.Builder(); retrofitBuilder.addConverterFactory(JacksonConverterFactory.create()); Retrofit retrofitAdapter = retrofitBuilder.baseUrl(baseUrl).build(); return retrofitAdapter.create(apiClass);

To get access to the raw response, use ResponseBody from okhttp as your call type.

Call<ResponseBody> login(...) 

In your callback, you can check the response code with the code method of the response. This applies to any retrofit 2 return type, because your callback always gets a Response parameterized with your actual return type. For asynchronous --

Call<ResponseBody> myCall = myApi.login(...) myCall.enqueue(new Callback<ResponseBody>() {     @Override     public void onResponse(Response<ResponseBody> response, Retrofit retrofit) {         // access response code with response.code()         // access string of the response with response.body().string()     }      @Override     public void onFailure(Throwable t) {         t.printStackTrace();     } }); 

for synchronous calls --

Response<ResponseBody> response = myCall.execute(); System.out.println("response code" + response.code());
