Retrofit2 Authorization - Global Interceptor for access token

Question

I\'m trying to use Retrofit2, I want to add Token to my Header Like this:

Authorization: Bearer Token but the <

Answer 1

If you want to add Bearer Token as a Header you can do those types of process.

This is one way to work with Bearer Token

In your Interface

@Headers({ "Content-Type: application/json;charset=UTF-8"})
@GET("api/Profiles/GetProfile")
Call getUser(@Query("id") String id, @Header("Authorization") String auth);

After that you will call the Retrofit object in this way

Retrofit retrofit  = new Retrofit.Builder()
                    .baseUrl("your Base URL")
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();

APIService client = retrofit.create(APIService.class);
Call calltargetResponse = client.getUser("0034", "Bearer "+token);
calltargetResponse.enqueue(new Callback() {
       @Override
       public void onResponse(Call call, retrofit2.Response response) {
           UserProfile UserResponse = response.body();
           Toast.makeText(this, " "+response.body(), Toast.LENGTH_SHORT).show();
                }
        @Override
        public void onFailure(Call call, Throwable t) {
            //Toast.makeText(this, "Failed ", Toast.LENGTH_SHORT).show();
        }
});

Another Way is using intercept, which is similar the previous Answer. But, that time you just need to modify interface little bit like.

@Headers({ "Content-Type: application/json;charset=UTF-8"})
@GET("api/Profiles/GetProfile")
Call getUser(@Query("id") String id); 

Hope this will work for you.
