the Exact error is System.Net.WebException: The Remote server returned an Error: (400) Bad Request. at system.Net.HttpWebRequest.GetResponse()我有一个在IIS中托管的WCF休息服务..我创建了一个简单的WPF应用程序只有一个按钮..现在我需要使用get ...来访问我的WCF服务中的方法。
这是WPF的代码

}
private void RestDemo_Click(object sender, RoutedEventArgs e)
{
string msg="";
HttpWebResponse resp=null;
//WebRequest my = WebRequest.Create(@"http://www.google.com");
//MessageBox.Show(my.ToString());
WebRequest myRequest = WebRequest.Create(@"http://localhost/REST/RestServicesSample.svc/XmlData/sad");
MessageBox.Show(myRequest.ToString());
//Provides response from a URI.
myRequest.Method = "GET";
myRequest.ContentType = @"text/xml; charset=utf-8";
try
{
resp=myRequest.GetResponse() as HttpWebResponse;
}
catch (WebException c)
{
MessageBox.Show(c.ToString());
}
if (resp.StatusCode == HttpStatusCode.OK)
{
XmlDocument myXMLDocument = new XmlDocument();
XmlReader myXMLReader = new XmlTextReader(resp.GetResponseStream());
myXMLDocument.Load(myXMLReader);
msg= myXMLDocument.InnerText;
}
MessageBox.Show(msg);
}
}
}
为什么我在myRequest.GetResponse()中收到错误..? 这是我的.svc.cs文件

using System.ServiceModel.Web;
namespace RestServices
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IRestServicesSample" in both code and config file together.

[WebGet]
////[WebInvoke(Method = "GET",
//// ResponseFormat = WebMessageFormat.Xml,

[OperationContract]
[WebInvoke(Method = "GET",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Wrapped,
UriTemplate = "json/{id}")]
string JsonData(string id);
}
}

有关服务配置,请查看:Can't connect to rest webservice through c# client
这是一个发出GET请求的示例C#客户端
string url = "localhost:8080/MyService.svc/Submit/" + "helloWorld";
string strResult = string.Empty;
HttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create(url);
webrequest.Method = "GET";
// set content type based on what your service is expecting
webrequest.ContentType = "application/xml";
//Gets the response
WebResponse response = webrequest.GetResponse();
//Writes the Response
Stream responseStream = response.GetResponseStream();
StreamReader sr = new StreamReader(responseStream);
string s = sr.ReadToEnd();
return s;
