android - 如何在android中使用改造修复401未经授权的错误？

Question

我在android中使用了retrofit2库。我收到 401 未经授权的错误。如果有人解决了这个问题，请在这里告诉我。我学习了在android中使用retrofit2。
这是 APIClient 类。
APIClient 类:

           public class APIClient {
                private static Retrofit retrofit = null;
                private static OkHttpClient okHttpClient = new OkHttpClient.Builder()
                        .connectTimeout(7, TimeUnit.MINUTES)
                        .readTimeout(7, TimeUnit.MINUTES)
                        .writeTimeout(7, TimeUnit.MINUTES)
                        .build();
                public static Retrofit getClient() {
                    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
                    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
                    OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();

                    retrofit = new Retrofit.Builder().baseUrl("http://www.example.com/").addConverterFactory(GsonConverterFactory.create())
                            .client(okHttpClient).build();

                    return retrofit;
                }
            }

这是我的界面。

                    public interface APIInterface {
                        @GET("/teacher/api/getStudentTakeAttendanceList")
                        Call<List<Apiresponse>> getstudentAttendanceListView(@Query("teacherId") int userId);

                    //    Callback<List<Apiresponse>> studentAttendanceListView(@Query("teacherId") int userId);
                    }         

这是我最后的呼吁。

final Call<List<Apiresponse>> getstudentAttendanceListView = apiInterface.getstudentAttendanceListView(userId);
            getstudentAttendanceListView.enqueue(new Callback<List<Apiresponse>>() {
                    @Override
                    public void onResponse(Call<List<Apiresponse>> call, Response<List<Apiresponse>> response) {
                        Log.d("responsecode:::", "" + response.code());

                        if (progressDialog.isShowing()) {
                            progressDialog.dismiss();
                        }

                        Log.e("response::", "" + response.errorBody());

    //                    Log.e("response::", "" + response.body());

                    }

                    @Override
                    public void onFailure(Call<List<Apiresponse>> call, Throwable t) {
                        call.cancel();
                        if (progressDialog.isShowing()) {
                            progressDialog.dismiss();
                        }

                    }
                });
in app.gradle file.
        compile 'com.squareup.retrofit2:retrofit:2.0.2'
        compile 'com.squareup.retrofit2:converter-gson:2.0.2'
    output.
    responsecode:::: 401
    response::: okhttp3.ResponseBody$1@537beb4c

Answer 1

A 401 Unauthorized error意味着您无权访问。
在您的情况下，这意味着您必须添加带有 accessToken 的 header 。

Here解释了如何做到这一点。
