HTTPClient Post请求，包含标题和正文

Question

我希望使用HttpClient设置Content-Type和Authorization头，并希望为body（请求）加载xml文件，并发送Post请求。

   HttpClient clientTest = new HttpClient();

   HttpRequestMessage httpRequest = new HttpRequestMessage(HttpMethod.Post,url);


   httpRequest.Content = new StringContent(string.Empty, Encoding.UTF8, "application/vnd.citrix.sessionparams+xml");
   httpRequest.Headers.Authorization = new AuthenticationHeaderValue("CitrixAuth", "H4sIAAAAAAAEAK1X2Y6jyBL9lZLnEbnZt1J");

XDocument xml = XDocument.Load("RequestSession.xml");

转换为document.toString（）

var httpContent = new StringContent(xml.Document.ToString(), Encoding.UTF8, "application/vnd.citrix.sessionstate+xml");

请帮助我使用HttpClient组合邮件请求的头和正文。

我不知道这是否是您正在调用的服务的有效请求，但要设置标题和正文并发送请求，它将如下所示：

HttpClient clientTest = new HttpClient();

HttpRequestMessage httpRequest = new HttpRequestMessage(HttpMethod.Post,url);

httpRequest.Content = new StringContent(xml.Document.ToString(), Encoding.UTF8, "application/vnd.citrix.sessionstate+xml");
httpRequest.Headers.Authorization = new AuthenticationHeaderValue("CitrixAuth", "H4sIAAAAAAAEAK1X2Y6jyBL9lZLnEbnZt1J");

var response = await clientTest.SendAsync(httpRequest);

如果您得到一个400坏请求，它是因为您发送的不适合API，而不是因为您发送它的方式。
