Question

我需要将以下文本发送到Web应用程序（MVC2）

你好<>〜！@＃$％^＆*（）_ + |} {“：？> << / p>
你好<>？:: P {{} | +）_）_＆*（）＆^ * ^％＆＃％^ @＃$〜！@＃〜！@＃〜Q

我正在使用Windows.Web.Http.HttpClient通过UWP应用发送此消息。但是，当从网上收到此消息时，它将引发异常。

“从客户端检测到一个潜在危险的Request.Form值（数据=” ..._＆*（）＆^ * ^％＆＃％^ @＃$〜！@＃〜！@＃〜Q“ ）。”

Android和iOS应用程序可以发送相同的消息，并且Web服务器可以毫无问题地接受该消息。有人可以在没有服务器端任何修改的情况下帮助我解决此问题吗？

这是我在UWP应用上使用的代码。如果需要任何更改，请告诉我。再次感谢。

func xmppOutgoingFileTransferIBBClosed(_ sender: XMPPOutgoingFileTransfer!) {
}

Windows.Web.Http.HttpClient帖子发送特殊字符（从客户端检测到潜在危险的Request.Form值）
