Question

我正在Android项目中使用Retrofit，想了解人们如何在Retrofit中构造其API。

因此，我有一些具有相同基础URL的API，现在我将它们全部放在一个interface中吗？还是根据使用情况放置它们？就像签名和身份验证合而为一，获取新闻提要数据并执行相关操作又是另一个？

Answer 1

我始终使用Retrofit和API，如下所示：

1）首先，我以特殊的Intent（第一步）定义所有API

2）然后，我为每个API创建一个控制器（第二步）

3），然后当我要使用它们时，如下所示：（第三步）

第一步

public interface OnlineShopAPI {

   String BASE_URL = "https://api.backtory.com/";


   @Headers({"X-Backtory-Authentication-Id:5a154d2fe4b03ffa0436a534"})
   @POST("auth/users")
   Call<User> registerUser(@Body User user);

   interface RegisterUserCallBack {

      void onResponse(boolean successful, String errorMessage, User user);

      void onFailure(String cause);

    }
}

第二步

 public class RegisterUserController {

     OnlineShopAPI.RegisterUserCallBack registerUserCallBack;

     public RegisterUserController(OnlineShopAPI.RegisterUserCallBack registerUserCallBack) {
    this.registerUserCallBack = registerUserCallBack;
}

     public void start(User user){
         Retrofit retrofit = new Retrofit.Builder()
                 .addConverterFactory(GsonConverterFactory.create())
                 .baseUrl(OnlineShopAPI.BASE_URL)
                 .build();

         OnlineShopAPI onlineShopAPI = retrofit.create(OnlineShopAPI.class);

         Call<User> call = onlineShopAPI.registerUser(user);
         call.enqueue(new Callback<User>() {
             @Override
             public void onResponse(Call<User> call, Response<User> response) {

                 Log.d("TAG" , "Response : " + response.code());

                 if (response.isSuccessful()){
                     registerUserCallBack.onResponse(true , null      ,response.body());
                 }else  {

                    registerUserCallBack.onResponse(false , errorResponse.getMessage() , null);

                 }
             }

             @Override
             public void onFailure(Call<User> call, Throwable t) {

                 Log.d("TAG" , "onFailure : " + t.getCause());

                 registerUserCallBack.onFailure(t.getCause().getMessage());
             }
         });

     }

 }

第三步

public class RegisterFragment extends Fragment {

private EditText username;
private EditText password;
private EditText email;

private Button register;
private MenuInflater inflater1;

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    return inflater.inflate(R.layout.fragment_register , container ,false);
}

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    findViews(view);

    register.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            RegisterUserController userController = new RegisterUserController(registerUserCallBack);
            User user = new User();
            user.setPassword(password.getText().toString());
            user.setUsername(username.getText().toString());
            user.setEmail(email.getText().toString());
            userController.start(user);
        }
    });
}

OnlineShopAPI.RegisterUserCallBack registerUserCallBack = new OnlineShopAPI.RegisterUserCallBack() {
    @Override
    public void onResponse(boolean successful , String errorMessage ,User user) {

        if (successful){
            Toast.makeText(getActivity() , "DONE " + user.getUsername() , Toast.LENGTH_LONG).show();
            loginUser();
        }else {
            Toast.makeText(getActivity() , errorMessage , Toast.LENGTH_LONG).show();
        }
    }


    @Override
    public void onFailure(String cause) {

        Toast.makeText(getActivity() , cause , Toast.LENGTH_LONG).show();

    }
};

private  void findViews(View view){

    username = view.findViewById(R.id.username);
    password = view.findViewById(R.id.password);
    email = view.findViewById(R.id.email);

    register = view.findViewById(R.id.register);

  }
}
