public interface ApiService {

}

import java.util.List;

                Log.w(TAG, "onFailure: " + t.getMessage());
            }
        });

    }

希望你能帮我。谢谢！

使用如下所示的“列表”广告：-

**Api interface**

公共接口ApiService{

@POST("register")
@FormUrlEncoded
Call<List<AccessToken>> register(@Field("name") String name, @Field("email") String email, @Field("password") String password);

@POST("login")
@FormUrlEncoded
Call<List<AccessToken>> login(@Field("username") String username, @Field("password") String password);

@GET("users")
Call<List<UserResponse>> users();

}

@OnClick(R.id.btn_get_user)
    void getUsers() {
        call = service.users();
        call.enqueue(new Callback<List<UserResponse>>() {
            @Override
            public void onResponse(Call<List<UserResponse>> call, Response<List<UserResponse>> response) {
                Log.w(TAG, "onResponse: " + response);

                if (response.isSuccessful()) {
                    username.setText(response.body().getData().get(0).getName());
                } else {
                    startActivity(new Intent(GameActivity.this, LoginActivity.class));
                    finish();
                    tokenManager.deleteToken();
                }

            }

            @Override
            public void onFailure(Call<List<UserResponse>> call, Throwable t) {
                Log.w(TAG, "onFailure: " + t.getMessage());
            }
        });

    }
