Question

我在尝试使用Okhttp进行改造时遇到了问题。我似乎不明白我做错了什么。

它显示错误：'Anonymous class derived from Callback' must either be declared abstract or implement abstract method 'onResponse(Response<T>, Retrofit)' in 'Callback'

在我的MainActivity中我有这个：

    OkHttpClient httpClient = new OkHttpClient();
            httpClient.interceptors().add(new Interceptor() {
                  @Override
                  public Response intercept(Interceptor.Chain chain) throws IOException {
                          Request original = chain.request();

                          Request request = original.newBuilder()
                          .header("User-Agent", "Your-App-Name")
                          .header("Content-Type", "application/json")
                          .header("Authorization","authorization_code")
                          .method(original.method(), original.body())
                          .build();

                          return chain.proceed(request);
                     }
            });


        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .client(httpClient)
                .build();
        TestInterface service = retrofit.create(TestInterface.class);



            Call<TestData> call = service.getPost();
/* It keeps pointing at this line below: 
'Callback' must either be declared abstract" */

            call.enqueue(new Callback<TestData>() {

                @Override
                public void onResponse(Response<TestData> response, Retrofit retrofit) {
                    // Get result Repo from response.body()
                    // response.isSuccess() is true if the response code is 2xx
                    int statusCode = response.code();
                    if (response.isSuccess()) {
                          System.out.println("Success: ");
                    } else {

                    }
                }

                @Override
                public void onFailure(Throwable t) {
                    System.out.println("failed: "+t);
                }
            });

在我的TestData界面中，我有这个

public interface TestInterface {

    @POST("/paths_to_web_directory")
    Call<TestData>
    getPost();
}

这是我在其他示例中看到的方式，所以也许我以错误的方式实现它。请纠正我。感谢

改装github项目有一个具有不同方法签名的样本。试试这个：

    call.enqueue(new Callback<TestData>() {    
        @Override public void onResponse(Call<TestData> call, Response<TestData> response) {  
        }
        @Override public void onFailure(Call<TestData> call, Throwable t) {
         }
});

使用Retrofit：2.0和Okhttp（拦截器）
