[英]Unable to consume web services using c# but working on postman
我正在尝试通过 httpwebrequest 调用 webservice。 已成功添加 XML 文档和标题,但仍然收到内部服务器错误 500 错误。 从调试模式复制的相同 xml 文档在邮递员上工作正常。 我的代码是
public HttpWebRequest CreateWebRequest(string url, string action)
{
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Headers.Add("SOAPAction",action);
//webRequest.Headers.Add("ContentType","text/xml;charset=\"utf-8\"");
webRequest.ContentType = "text/xml;charset=\"utf-8\"";
// "charset=\"utf-8\"";
webRequest.Accept = "text/xml";
webRequest.Method = "POST";
return webRequest;
}
public string CallWebService()
{
try
{
var _url = "https://xxxxxxxxxx/siebel/app/eai/enu?SWEExtSource=WebService&SWEExtCmd=Execute&WSSOAP=1";
var _action = @"""document/http://yyyyyy/:CreateFollowup""";
XmlDocument soapEnvelopeXml = CreateSoapEnvelope();
ServicePointManager
.ServerCertificateValidationCallback +=
(sender, cert, chain, sslPolicyErrors) => true;
HttpWebRequest webRequest = CreateWebRequest(_url, _action);
//InsertSoapEnvelopeIntoWebRequest(soapEnvelopeXml, webRequest);
Invoke(new Action(() =>
{
listBox_Log.Items.Add("saving soapenvelope.");
}));
soapEnvelopeXml.Save(webRequest.GetRequestStream());
// begin async call to web request.
IAsyncResult asyncResult = webRequest.BeginGetResponse(null, null);
// suspend this thread until call is complete. You might want to
// do something usefull here like update your UI.
asyncResult.AsyncWaitHandle.WaitOne();
// get the response from the completed web request.
string soapResult = null;
using (WebResponse webResponse = webRequest.EndGetResponse(asyncResult))
{
Invoke(new Action(() =>
{
listBox_Log.Items.Add("fetching response");
}));
using (StreamReader rd = new StreamReader(webResponse.GetResponseStream()))
{
Invoke(new Action(() =>
{
listBox_Log.Items.Add("collecting response");
}));
soapResult = rd.ReadToEnd();
}
Console.Write(soapResult);
}
return soapResult;
}
catch(Exception ex)
{
throw ex;
}
}
public XmlDocument CreateSoapEnvelope()
{
XmlDocument soapEnvelop = new XmlDocument();
soapEnvelop.LoadXml(@"xml code");
return soapEnvelop;
}
我还尝试绕过 ssl 证书,因为 webservice 服务器 ssl 证书已过期或不受信任。 请帮忙,因为我被卡住了。 我也尝试过 WSDL 文件,但也无法成功。
解决了
经过艰苦的寻找,不知何故,我知道如果 webservice 在邮递员上成功运行,它还会提供该语言的代码(就在保存按钮下方)。 所以我使用了该代码(基于RestClient )。 我的错误是没有在 xml doc 中使用 \\r\\n 和适当的空格。 所以 xml 是问题所在。
//THis code used for ssl bypassing

RestSharp.IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
return response.Content.ToString();
