Question

这是我第一次使用改装，我迷失了说明。我阅读了官方指南和其他一些答案和教程，但我仍然遇到麻烦。看起来它们都涵盖了复杂的场景，但不仅仅是一个领域的简单帖子。

这是我想要做的细节。将名称发布到php服务器：

输入：application / x-www-form-urlencoded 有效负载名称：例如名称=约翰％20Smith

我花了很多时间并且有基本的但我认为我错过了一些东西：

我已经知道我需要这样的界面：

public interface ApiService {

    @FormUrlEncoded
    @POST("./")
    Call<User> updateUser(@Field("Name") String name);
}

然后我为我的用户提供了一个模型：

public class User {
    @SerializedName("Name")
    String name;
}

然后我有我的改装客户：

公共类RetroClient {

private static final String ROOT_URL = "http://alarm.abc.ch/";
public static ApiService RETROFIT_CLIENT;

    public static ApiService getInstance() {
        //if REST_CLIENT is null then set-up again.
        if (RETROFIT_CLIENT == null) {
            setupRestClient();
        }
        return RETROFIT_CLIENT;
    }

    private static void setupRestClient() {
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(ROOT_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
        RETROFIT_CLIENT = retrofit.create(ApiService.class);
    }
}

我在我的主要活动的post函数中这样称呼它：

 public void post (){
        mRetrofitCommonService = RetroClient.getInstance();

        call = mRetrofitCommonService.updateUser("test");
        call.enqueue(new Callback<User>() {
            @Override
            public void onResponse(Call<User> call, Response<User> response) {

                System.out.println("responseee  " + response);
            }

            @Override
            public void onFailure(Call<User> call, Throwable t) {
                System.out.println("eeee " + t);
            }
        });

从那里我完全迷失了。我确信这是我想念的小东西，但不确定是什么。

提前感谢您的帮助。

编辑：代码已更改以反映我当前的尝试。这给了我以下错误：

MalformedJsonException: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 2 path

Answer 1

你快到了！现在你必须打电话给你的api。

示例代码

public class App {

    private ApiService apiService = RetroClient.getApiservice();

    public static void main(String[] args) {

        User user = new User("username")
        Call<User> call = apiService.updateUser(user);
        call.enqueue(new Callback<User>() {
            @Override
            public void onResponse(Call<User> call, Response<User> response) {
                int statusCode = response.code();
                User user = response.body();
                // process success
            }

            @Override
            public void onFailure(Call<User> call, Throwable t) {
                // process failure
            }
        });

    }

}

使用主要活动的post（）方法进行更新

public void post() {

    Call<User> call = apiService.updateUser("username");
    call.enqueue(new Callback<User>() {
        @Override
        public void onResponse(Call<User> call, Response<User> response) {
            int statusCode = response.code();
            User user = response.body();
        }

        @Override
        public void onFailure(Call<User> call, Throwable t) {
            // Log error here since request failed
        }
    });

}

Answer 2

在getApiService()返回的对象上，您可以致电updateUser()。

在回复此调用后，您将收到如下所示的Call对象：

Call<User> userUpdateCall = RetroClient.getApiService().updateUser(somestring);

然后同步执行此调用请执行以下操作：

userUpdateCall.execute();

<强>更新

抱歉，我以前错过了。在ApiService界面中，执行以下操作：

@FormUrlEncoded
@POST("YourPostEndpoint")
Call<User> updateUser(@Field("Name") String name);

ASYNC CALL

有关详细信息，请参阅here

要异步调用它，而不是.execute()使用以下代码（从上面链接获取的代码并修改为此方案：

userUpdateCall.enqueue(new Callback<User>() {  
    @Override
    public void onResponse(Call<User> call, Response<User> response) {
        if (response.isSuccessful()) {
            // user available
        } else {
            // error response, no access to resource?
        }
    }

    @Override
    public void onFailure(Call<List<Task>> call, Throwable t) {
        Log.d("Error", t.getMessage());
    }
}

Answer 3

请参阅我的onCreate方法我是如何做到的。

public class LoginActivity extends AppCompatActivity {

    RetrofitCommonService mRetrofitCommonService;
    Call<LoginResponse> call;
    String firstName, lastName, userId, token;

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

        mRetrofitCommonService = RetrofitClient.getInstance();

        call = mRetrofitCommonService.doLogin("danish.sharma@gmail.com", "12345678");
        call.enqueue(new Callback<LoginResponse>() {
            @Override
            public void onResponse(Call<LoginResponse> call, Response<LoginResponse> response) {
                LoginData responseReg = response.body().getData();

                firstName = responseReg.getFirstName();
                lastName = responseReg.getLastName();
                userId = responseReg.getUserId();
                token = responseReg.getToken();

                System.out.println("responseee  " + firstName + " " + lastName);
            }

            @Override
            public void onFailure(Call<LoginResponse> call, Throwable t) {
                System.out.println("eeee " + t);
            }
        });
    }
}

我的RetrofitClient类：

import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;

/**
 * Created by Danish.sharma on 7/22/2016.
 */
public class RetrofitClient {
    public static final String BASE_URL = "http://face2friend.com/";
    public static RetrofitCommonService RETROFIT_CLIENT;


    public static RetrofitCommonService getInstance() {
        //if REST_CLIENT is null then set-up again.
        if (RETROFIT_CLIENT == null) {
            setupRestClient();
        }
        return RETROFIT_CLIENT;
    }

    private static void setupRestClient() {
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
        RETROFIT_CLIENT = retrofit.create(RetrofitCommonService.class);
    }
}

＆安培; RetrofitCommonService类：

import com.aquasoft.retrofitexample.model.LoginResponse;
import com.aquasoft.retrofitexample.model.RegistrationResponse;
import com.aquasoft.retrofitexample.model.UserImageResponse;
import com.aquasoft.retrofitexample.model.VehicleResponse;

import okhttp3.MultipartBody;
import okhttp3.RequestBody;
import retrofit2.Call;
import retrofit2.http.Field;
import retrofit2.http.FormUrlEncoded;
import retrofit2.http.Multipart;
import retrofit2.http.POST;
import retrofit2.http.Part;

/**
 * Created by Danish.sharma on 7/22/2016.
 */
public interface RetrofitCommonService {

    /*@POST("http://server.pogogamessupport.com/parkway/api/v1/registration")
    Call<RegistrationResponse> createUser(@Body RegistrationResponse user);*/

    @FormUrlEncoded
    @POST("registration")
    Call<RegistrationResponse> doRegistration(@Field("email") String email, @Field("firstname") String firstname, @Field("lastname")
    String lastname, @Field("password") String password);

    @FormUrlEncoded
    @POST("login")
    Call<LoginResponse> doLogin(@Field("email") String email, @Field("password") String password);

    @FormUrlEncoded
    @POST("listvehicle")
    Call<VehicleResponse> getAllVehicle(@Field("userId") String userId, @Field("token") String token);

    @Multipart
    @POST("updateprofilepic")
    Call<UserImageResponse> updateUserImage(@Part("userId") RequestBody userId, @Part("token") RequestBody  token, @Part MultipartBody.Part image);

}

＆安培;关于build.gradle中依赖项的最后一件事，我正在使用：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.google.code.gson:gson:2.6.2'
    compile 'com.squareup.retrofit2:retrofit:2.1.0'
    compile 'com.squareup.retrofit2:converter-gson:2.1.0'
    compile 'com.squareup.okhttp:okhttp:2.4.0'
    provided 'org.glassfish:javax.annotation:10.0-b28'
}
