在 linux(ubuntu) .net core 2.2 版本下，Face接口调用操作超时。

在 linux(ubuntu) .net core 2.2 版本下，Face接口调用操作超时。
代码在window下正常。
网络访问正常，token能正常获得并输出。
单独wget api 地址，正常。

猜测，设置的某些入参会导致在linux下被卡到超时。

我用WebClient组件改写了网络请求功能，现在能调用了。
目前结论是，HttpWebRequest组件要么使用上有瑕疵，要么HttpWebRequest在linux下兼容不好。
建议将组件在linux下做一下兼容性测试，再更新一个版本吧。
