方法call.enqueue()不调用。而且我放弃了为什么?请帮忙。

我将Retrofit2用于POST请求。这是我简单的项目示例。

我有名为FaceAPI类的API服务。码:

package com.facelocation.testretrofit;

import okhttp3.ResponseBody;
import retrofit2.Call;
import retrofit2.http.Body;
import retrofit2.http.POST;


public interface FaceAPI {

    @POST("api/auth/register")
    Call<ResponseBody> registerUser(
            @Body RegistrationBody body
    );
}


我有一个RegistrationBody类,我正在尝试以JSON格式(仅两个参数-电子邮件和密码)将其推入服务器。码:

package com.facelocation.testretrofit;

public class RegistrationBody {
    public String email;
    public String password;

    public RegistrationBody(String email, String password) {
        this.email = email;
        this.password = password;
    }
}


我只有一个按钮,拥有最简单的MainActivity类。码:

package com.facelocation.testretrofit;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import okhttp3.ResponseBody;
import retrofit2.Call;
import retrofit2.Callback;
import retrofit2.Response;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;

public class MainActivity extends AppCompatActivity {

    String TAG = "Reg";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button button = (Button) findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Retrofit retrofit = new Retrofit.Builder()
                        .baseUrl("https://face-location.com/")
                        .addConverterFactory(GsonConverterFactory.create())
                        .build();

                FaceAPI api = retrofit.create(FaceAPI.class);
                RegistrationBody reg = new RegistrationBody("[email protected]", "password12");

                Call<ResponseBody> call = api.registerUser(reg);
                Log.i(TAG, "Works until here");

                call.enqueue(new Callback<ResponseBody>() {
                    @Override
                    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                        Toast.makeText(MainActivity.this, "Все прошло хорошо",Toast.LENGTH_SHORT).show();
                        Log.i(TAG, "THIS METHOD DOESN'T CALL! WHY?" + response.toString());

                    }

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

                    }
                });
            }
        });
    }
}


当我运行这段代码时,我没有任何错误。而且我没有任何服务器响应。这行代码适用于Log.i(TAG,“直到这里工作”);但是我认为下一个方法不会调用。我不明白为什么我没有收到任何错误或服务器响应。请帮忙!

最佳答案

因此,问题主要出在您的RegistrationBody()中。

首先将RegistrationBody()更改为String

您可以自由使用以下代码来实现:

public static String modelAsString(Object obj) {
        String value;
        ObjectMapper mapper = new ObjectMapper();
        try {
            value = mapper.writeValueAsString(obj);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
            return e.getMessage();
        }
        return value;
    }


看起来像

RegistrationBody reg = new RegistrationBody("[email protected]", "password12");
String modelAsString = modelAsString(req)


并在活动中添加您的mediaType

  public static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");


之后,使您的requestModel如下所示:

RequestBody requestBody = RequestBody.create(JSON, modelAsString);


不要忘记!来自okhttp3的此请求正文,
这意味着您必须import okhttp3.RequestBody

毕竟让您喜欢

Call<ResponseBody> call = api.registerUser(requestBody);


让我知道它是否有效!!!!
