改造方法不执行

Question

我有一个 Android 客户端和一个使用 ASP Web API 构建的 Rest API。我的问题仅在一个请求中，onSuccess() 和 onFailure() 方法不执行，API 的返回值为 Null。但是请求工作正常（我使用 OkHttp 进行了检查）。但其他请求完美运行。我尝试使用execute() 运行它，但我使用的是NetworkOnMainThreadException。

这是我的 OkHttp 部分：

    OkHttpClient.Builder client = new OkHttpClient.Builder();
    HttpLoggingInterceptor loggingInterceptor = new 
    HttpLoggingInterceptor();
    loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

    client.addInterceptor(new Interceptor() {
        @Override
        public Response intercept(Chain chain) throws IOException {
            Request request = chain.request();
            Request.Builder requestBuilder = request.newBuilder();
            requestBuilder.addHeader("Accept", "application/json");
            requestBuilder.addHeader("Content-type", " application/json");
            if (SharedPrefs.isAuthorized(CApplication.appContext)) {
                String token = "bgbqdjsbfjsadnvas";
                requestBuilder.addHeader("Authorization", token);
            }
            requestBuilder.method(request.method(), request.body());


            return chain.proceed(requestBuilder.build());
        }
    }).addInterceptor(loggingInterceptor);

    mRetrofit = new Retrofit.Builder()
            .baseUrl(ClientConfig.BASE_URL)
            .client(client.build())
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    restInterface = mRetrofit.create(RestInterface.class); 

这是我的请求：

M_Contact mContact = new M_Contact();
Call<M_Contact> call = rest.getAllContacts(userId);
call.enqueue(new Callback<M_Contact>() {
@Override
public void onResponse(Call<M_Contact> call, Response<M_Contact> response) {
    if (null != response) {
        if (response.isSuccessful()) 
            Toast.makeText(mContext, "Success: " + response.code(), Toast.LENGTH_SHORT).show()
        else 
            Toast.makeText(mContext, "Something Happened: " + response.code(), Toast.LENGTH_SHORT).show();      
    }
    else Toast.makeText(mContext, "No Data", Toast.LENGTH_SHORT).show(); 
}
@Override
public void onFailure(Call<M_Contact> call, Throwable t) {
    Toast.makeText(mContext, "Failed: " + t.getMessage(), Toast.LENGTH_SHORT).show();  
    }
});

System.out.println("request finished");

这是我的 build.gradle 文件：

compile('com.squareup.retrofit2:retrofit:2.2.0') {
    exclude module: 'okhttp'
}
compile 'com.squareup.okhttp3:okhttp:3.6.0'
compile 'com.squareup.okhttp3:logging-interceptor:3.6.0'
compile 'com.squareup.retrofit2:converter-gson:2.2.0'

这是我的日志文件：

我非常感谢任何形式的帮助。谢谢

更新： 再次结束，请求结果是成功的，但是，这两种方法（onSuccess() 和onFailure()）不起作用。他们甚至没有开始。 我刚刚更新了请求部分。就好像call.enqueue(...行开始后，突然跳到System.out.println('...');行，没有经过onSuccess()和onFailure();。

更新

这是我的响应数据结构：

class M_Contact{
    public int userId;
    public List<ContactModel> contactList;
    public int contactCount;
    public int phoneNumberCount;
    public M_Device userDevice;
    public boolean isCacheAvailable;
}

class ContactModel{
    public int id;
    public String name;
    public List<M_ContactPhoneNumber> phoneNumberList;
}

class M_ContactPhoneNumber{
    public int id;
    public String phoneNumber;
    public String isPrimary;
    public String label;
}

class M_Device{
    public String model;
    public String serial;
}

为了便于阅读，我删除了 getter 和 setter 等方法。

Answer 1

我知道这很愚蠢，但我只是通过更改请求执行行来解决问题。起初，请求在onCreate() 的最后一行执行，但是当我将其删除到onCreate() 的第一行时，它解决了：| 如果有人知道为什么会这样，我也会很感激让我知道。

谢谢！
