android - 使用 Retrofit 2 向请求添加 header

Question

我正在尝试发送带有身份验证 header 的请求，但服务器似乎无法识别客户端。我用了this教程，并实现了一个拦截器，如下所示:

public class AuthenticationInterceptor implements Interceptor {

private String authId;
private String authToken;

public AuthenticationInterceptor(String authId, String authToken) {
    this.authId = authId;
    this.authToken = authToken;
}

@Override
public Response intercept(@NonNull Chain chain) throws IOException {
    Request original = chain.request();
    Request.Builder builder = original.newBuilder();

    if (authId != null && authToken != null) {
        Timber.d("adding auth headers for: " + this);
        builder.header("auth_id", authId)
                .header("auth_token", authToken);
    }

    Request request = builder.build();
    return chain.proceed(request);
  }
}

当我尝试向服务器发送经过身份验证的请求时，它返回错误响应 409。服务器人员告诉我我缺少那些参数:(例如，由 Postman 接收)

    “accept”: [
        “*/*”
    ],
    “accept-encoding”: [
        “gzip, deflate”
    ],
    “cookie”: [
        “PHPSESSID=ah1i1856bkdln5pgmsgjsjtar3"
    ]

• 我认为使用 Dagger2 可能会导致此问题(请参阅 here )，所以我隔离了 okHttpClient，但它仍然不起作用。

• 这是我的用法实现(非常简单):

  Retrofit retrofit;
  OkHttpClient client;
  AuthenticationInterceptor authenticationInterceptor;
  HttpLoggingInterceptor loggingInterceptor;
  
  private void testHeaders() {
  loggingInterceptor = new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {
      @Override
      public void log(String message) {
          Timber.i(message);
      }
  });
  loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
  
  client = new OkHttpClient.Builder()
          .addInterceptor(loggingInterceptor)
          .build();
  
  retrofit = new Retrofit.Builder()
          .addConverterFactory(GsonConverterFactory.create())
          .client(client)
          .baseUrl(BuildConfig.SERVER_ADDRESS)
          .build();
  
  retrofit.create(EntrOnline.class).getLoginToken("email@email.com", "XXX").enqueue(new Callback<NewAccount>() {
      @Override
      public void onResponse(Call<NewAccount> call, Response<NewAccount> response) {
  
          authenticationInterceptor = new AuthenticationInterceptor(response.body().getAuthId(), response.body().getAuthToken());
  
          client = new OkHttpClient.Builder()
                  .addInterceptor(loggingInterceptor)
                  .addInterceptor(authenticationInterceptor)
                  .build();
  
          retrofit = new Retrofit.Builder()
                  .addConverterFactory(GsonConverterFactory.create())
                  .client(client)
                  .baseUrl(BuildConfig.SERVER_ADDRESS)
                  .build();
  
          retrofit.create(EntrOnline.class).getKeys("50022d8a-b309-11e7-a902-0ac451eb0490").enqueue(new Callback<List<NewEkey>>() {
              @Override
              public void onResponse(Call<List<NewEkey>> call, Response<List<NewEkey>> response) {
                  Timber.d("Test Api");
              }
  
              @Override
              public void onFailure(Call<List<NewEkey>> call, Throwable t) {
  
              }
          });
  
      }
  
      @Override
      public void onFailure(Call<NewAccount> call, Throwable t) {
  
      }
  });
  

谢谢!
