C# 使用SSL协商对Web Api进行http请求的UWP应用程序

我正在尝试通过证书协商将UWP应用程序连接到启用了Web Api SSL（在IIS中）的Web Api。如果禁用证书协商，则以下代码可以工作，请求也可以工作，但没有客户端证书到达附加到请求的Web Api。提到firefox在GET请求时协商证书，一切都按预期工作（服务器接收证书）

private async void btn\u addCertificate\u单击（对象发送方，路由目标）
{
尝试
{
Windows.Web.Http.HttpResponseMessage响应=等待testCertConnect（）；
字符串responseBodyAsText；
System.Diagnostics.Debug.WriteLine（response.StatusCode+“”+response.ReasonPhrase+Environment.NewLine）；
responseBodyAsText=wait response.Content.ReadAsStringAsync（）；
系统.诊断.调试.写入线（responseBodyAsText）；
}
捕获（例外情况除外）
{
System.Diagnostics.Debug.WriteLine（例如ToString（））；
}
}
专用异步任务testCertConnect（）
{
Windows.Web.Http.Filters.HttpBaseProtocolFilter=新建Windows.Web.Http.Filters.HttpBaseProtocolFilter（）；
filter.ClientCertificate=certList[this.certificatesListCB.SelectedIndex]；
Windows.Web.Http.HttpClient HttpClient=新的Windows.Web.Http.HttpClient（过滤器）；
httpClient.DefaultRequestHeaders.UserAgent.tryparsead（“Mozilla/5.0（Windows NT 10.0；Win64；x64）AppleWebKit/537.36（KHTML，类似Gecko）Chrome/46.0.2486.0 Safari/537.36 Edge/13.10586”）；
httpClient.DefaultRequestHeaders.AcceptEncoding.tryparsead（“gzip，deflate”）；
httpClient.DefaultRequestHeaders.Add（“Pragma”，“无缓存”）；
返回wait-wait-httpClient.GetAsync（新Uri（“https://:44300/api/sites”）；
}

applicationhost.config中的SSL配置

<access sslFlags="Ssl, SslNegotiateCert" />

在SSL协商处于活动状态时执行请求时出错

注意：SSL证书是CA证书签名的，并且各自的PKI加载到证书存储。

我面临同样的问题。你能解决吗？@LohithKorupolu没有。很抱歉耽搁了。我也面临同样的问题。你能解决吗？@LohithKorupolu没有。很抱歉耽搁了。
