c# - 我如何使用 post 方法调用 Rest Web 服务并在 C# 中发送 xml 数据

Question

我在这里尝试做的是使用 xml 数据向 Rest web 服务发出 post 请求。

这是我现在拥有的，但我不确定如何传递我的 xml 数据

            XElement xml = new XElement("MatchedOptions",
               from m in _matchedOptionsList
               select new XElement("Listing",
                       new XElement("DomainID", _trafficCopInputs.DomainID),
                       new XElement("AdSource", _trafficCopInputs.AdSource),
                       new XElement("Campaign", _trafficCopInputs.Campaign),
                       new XElement("AdGroup", _trafficCopInputs.AdGroup),
                       new XElement("RedirectURL", m.RedirectPath),
                       new XElement("FunnelKeyword", m.FunnelKeyword)));

            HttpWebRequest req = WebRequest.Create("http://something.com/")
                 as HttpWebRequest;


            req.Method = "POST";
            req.ContentType = "text/xml";
            req.ContentLength = 0;
            StreamWriter writer = new StreamWriter(req.GetRequestStream());
            writer.WriteLine(xml.ToString());

我使用 WebClient 类:

WebClient webClient = new WebClient();
using (webClient)
{
   requestInterceptor.OnRequest(webClient);
   var enc = new ASCIIEncoding();
   return enc.GetString(webClient.UploadData(uri, enc.GetBytes(dataAsString)));
}
