C# 如何将包含XML的长字符串发布到Web API
我试图将一个长字符串(包含XML)发布到我的Web API控制器,但失败得很惨 如果TextAsXml很短,那么下面的方法可以工作,但是当TextAsXml很长时,它会失败“无效URI:URI字符串太长”,这是可以理解的C# 如何将包含XML的长字符串发布到Web API,c#,xml,httpclient,asp.net-web-api,C#,Xml,Httpclient,Asp.net Web Api,我试图将一个长字符串(包含XML)发布到我的Web API控制器,但失败得很惨 如果TextAsXml很短,那么下面的方法可以工作,但是当TextAsXml很长时,它会失败“无效URI:URI字符串太长”,这是可以理解的 // Client code using (var client = new HttpClient()) { var requestUri = "http://localhost:49528/api/some"; var content = new FormUrlEnc

将XML作为内容发送而不使用Uri编码。我已经了解到的部分:-)但是如何发送呢?正如您在我的示例中看到的,该示例导致500个内部服务器错误,我使用MultipartFormDataContent调用PostAsync,但运气不佳。
// This results in 500 Internal server error.
using (var client = new HttpClient())
{
var requestUri = "http://localhost:49528/api/some";
var textAsXml = File.ReadAllText("Note.xml");
var content = new MultipartFormDataContent();
content.Add(new StringContent("John Doe"), "Author");
content.Add(new StringContent(textAsXml), "TextAsXml");
var response = client.PostAsync(requestUri, content).Result;
response.EnsureSuccessStatusCode();
