作为一个模拟项目，我让一个控制器向另一个控制器发送请求，在该控制器中，发送者模拟外部API。
我正在使用restsharp库，因为我可以更好地了解异常消息，并且对我来说更容易使用。
请求将发送到另一个端点，如下所示：
string url = $"{BaseUrl}/api/orders/post3";
string rawXml = "<?xml version='1.0' encoding='UTF-8'?><xml><quote>26</quote></xml>";
var client = new RestClient(url);
var request = new RestRequest()
{
RequestFormat = DataFormat.Xml,
XmlSerializer = new RestSharp.Serializers.DotNetXmlSerializer(),
Method = Method.POST,
XmlNamespace = null
};
request.AddXmlBody(rawXml);
var response = client.Post(request);
这是抛出的完整异常：

我已经浏览过多个帖子，但都出现了相同的错误，但是没有一个帮助。
但是，我还必须提到，接收方控制器还处理来自其他控制器的其他请求，这些请求工作正常。
非常感谢！
