java - Retrofit 需要太多时间才能得到响应

Question

我正在为 REST API 调用使用改造。使用 POSTMAN 客户端检查时，我可以在几分之一秒内得到响应。我用不到一秒钟的时间得到回应。当我使用 retrofit 调用请求时，它需要超过 5 到 10 秒才能获得响应。它显示我的应用程序运行速度较慢。请给我一个解决方案。

注意:在 .NET 中创建的 Web API

下面是我的代码

//Retrofit client code:

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient client = new 
            OkHttpClient.Builder().addInterceptor(interceptor)
                                .connectTimeout(600, TimeUnit.SECONDS)
                                .readTimeout(600, TimeUnit.SECONDS)
                                .build();


    if (client != null) {
        ConnectionPool pool = client.connectionPool();
        if (pool != null) {

            pool.evictAll();
        }
    }

    if (retrofit==null) {
        retrofit = new Retrofit.Builder()
                .baseUrl(baseUrl)
                .addConverterFactory(GsonConverterFactory.create())
                .client(client)
                .build();
    }

我的请求电话如下:

 private void makeServiceCallUPSData(String upsNameId, String spvId) {
    showLoadingView();

    if (calledFrom.equals(Constants.UPS_EDIT)) {
        logId = upsId;
    } else {
        logId = "0";
    }

    apiService.getUPSData(upsNameId, spvId, logId, authorizationToken).enqueue(new Callback<UPSDataResponse>() {
        @Override
        public void onResponse(Call<UPSDataResponse> call, Response<UPSDataResponse> response) {

            if (response.isSuccessful()) {
                UPSDataResponse upsDataResponse = response.body();
                hideLoadingView();
                if (upsDataResponse.getCode() == Constants.RESPONSE_SUCCESS) {
                    updateUI(upsDataResponse);
                } else {
                    showErrorAlertDialog(upsDataResponse.getMessage());
                }
                Logger.infoLog("Logg resp " + response.body());
            }
        }

        @Override
        public void onFailure(Call<UPSDataResponse> call, Throwable t) {
            //dismissProgressDialog();
            hideLoadingView();
            //Toast.makeText(thisActivity, "Server not Responsding. Try after Sometime", Toast.LENGTH_SHORT).show();
        }
    });
}

还添加了以下日志:

在上面的日志中，可以看到End GET 和200 OK 之间的时间差。同样，我也遇到了延迟，这类似于应用运行速度变慢。

在你的updateUI(upsDataResponse) 方法中从response fill recyclerview,listview 或任何其他字段一次填充
