Question

请帮忙，我正在android应用程序和服务器之间建立连接，我使用android和nginx的改装作为代理，当我使用postMan时，一切正常，但是当我通过android应用程序尝试时，我收到了消息

{"timestamp":1548830303461,"status":500,"error":"Internal Server Error","exception":"java.lang.NullPointerException","message":"No message available"

这是我的代码：

final String key = Constant.getKey(24);
    System.out.println("asd key "+key);
    OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
    httpClient.addInterceptor(new Interceptor() {
        @Override
        public okhttp3.Response intercept(Chain chain) throws IOException {
            Request original = chain.request();
            Request request = original.newBuilder()
                    .addHeader("authorization_token",key)
                    //.header("authorization_token",key)
                    //.header("partner_identifier",Constant.PARTNER_IDENTIFIER)
                    //.header("partner_auth",Constant.PARTNER_AUTH)
                    .method(original.method(), original.body())
                    .build();
            return chain.proceed(request);
        }
    });



    OkHttpClient client = httpClient.build();
    System.out.println("asd ip "+Constant.URL_SERVICE_SECURE);
    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(Constant.URL_SERVICE_SECURE)  //http://backendService/login}

            .addConverterFactory(ScalarsConverterFactory.create())
            .addConverterFactory(GsonConverterFactory.create())
            .client(client)
            .build();

    ApiService apiInterface = retrofit.create(ApiService.class);
    paramObject = new JSONObject();
    try{
        tripleDes = new TripleDes(key);
        paramObject.put("msisdn",txtPhoneNumber.getText());
        encryptedBody = tripleDes.encrypt(paramObject.toString());
    }catch (JSONException e){
        System.out.println("asd JSON Exception : "+e.toString());
    }catch (Exception e){
        System.out.println("asd encrypt error :"+e.toString());
    }
    System.out.println("asd enc "+encryptedBody);
    Call<String> call = apiInterface.check_msisdn(encryptedBody);
    call.enqueue(new Callback<String>() {
        @Override
        public void onResponse(Call<String> call, Response<String> response) {
            try{
                System.out.println("asd respon 1"+response.errorBody().string());
                System.out.println("asd respon 2"+response.message().toString());
                System.out.println("asd respon 3"+response.raw().toString());
                System.out.println("asd respon 4"+response.code());

               }else{
                   Snackbar.make(getView(),valueUser.rm,Snackbar.LENGTH_SHORT).show();
               }

            }catch (Exception e){
                System.out.println("asd catch "+e.toString());
                Snackbar.make(getView(),"Cannot processing server's response !",Snackbar.LENGTH_SHORT).show();
            }
            progressDialog.dismiss();
        }

        @Override
        public void onFailure(Call<String> call, Throwable t) {
            Snackbar.make(getView(),"Oops, Something wrong please try again later or check your internet connection",Snackbar.LENGTH_SHORT).show();
            System.out.println("asd failure "+t.toString());
            progressDialog.dismiss();
        }
    });

}

使用Nginx服务器时出现此错误，如果我使用的服务器不使用代理服务器，则可以正常工作

在此先感谢您，谢谢您使用的语言

nginx服务器无法从改造中读取标头
