我有一个c#winforms应用程序,我试图调用一个我控制代码的Web服务(两端)。我知道Web服务很好,因为我可以从jquery中调用它而没有任何问题,并且返回了有效的json。但是当我从c#调用它时,我收到此错误:"远程服务器返回错误:(500)内部服务器错误。"在调试器中,我无法收集到更多细节。
这是我的c#来电代码:
private string GetMemberCheckInData() {
string response = string.Empty;
string fullURL = RootServiceURL + "MemberCheckIn";
var httpWebRequest = (HttpWebRequest) WebRequest.Create(fullURL);
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = "POST";
using(var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream())) {
string json = "{\"scanCode\":\"" + APIKey + "\"," +
"\"siteID\":\"2\"," +
"\"revenueGroupID\":\"0\"," +
"\"employeeID\":\"12345\"}";;
streamWriter.Write(json);
streamWriter.Flush();
streamWriter.Close();
var httpResponse = (HttpWebResponse) httpWebRequest.GetResponse();
using(var streamReader = new StreamReader(httpResponse.GetResponseStream())) {
response = streamReader.ReadToEnd();
}
}
return response;
}
以下是正在发送的文字JSON:
{"scanCode":"***8G9V3MA39H0N****","siteID":"2","revenueGroupID":"0","employeeID":"12345"}
这是c#web服务代码(从jquery调用时工作正常):
[WebMethod]
public void MemberCheckIn(string scanCode, int siteID, int revenueGroupID, int employeeID)
{
...code is never reached...
}
实际上从未输入过Web服务功能;我用调试器证实了这一点。当我从jquery调用它时,我可以调试它。因此,似乎该请求被.net运行时或IIS等拒绝。
任何想法我做错了什么?

您的网络方法希望您将参数传递给它。
string fullURL = RootServiceUrl + "MemberCheckIn?scanCode=X&siteID=1...etc.
