我們將一些web服務從asmx升級到了WCF,我需要在應用程序中更改對Web服務的調用,合約名稱和方法名稱和簽名是相同的。 有沒有簡單的方法可以從調用一個asmx Web服務到一個svc Web服務(WCF)?從asmx切換到svc web服務
internal XmlDocument ServiceCall()
{
WebResponse reponseWeb = null;
string strReponse = string.Empty;
HttpWebRequest webRequest = this.CreateWebQuery();
XmlDocument soapEnvelopeXml = this.CreerEnveloppeSoap();
using (Stream stream = webRequest.GetRequestStream())
{
soapEnvelopeXml.Save(stream);
}
XmlDocument xmlSoapRequest = new XmlDocument();
try
{
reponseWeb = webRequest.GetResponse();
}
catch (System.Exception ex)
{
throw ex;
}
Stream str = reponseWeb.GetResponseStream();
StreamReader sr = new StreamReader(str);
xmlSoapRequest.Load(sr);
return xmlSoapRequest;
}
private HttpWebRequest CreateWebQuery()
{
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(this.UrlServiceWeb);
webRequest.Headers.Add("SOAPAction", "\"" + this.UrlHost + this.WCFNameContrat + "/" + this.MethodeWeb + "\"");
webRequest.ContentType = "application/soap+xml; charset=utf-8";
webRequest.Accept = "text/xml";
webRequest.Method = "POST";
return webRequest;
}
private XmlDocument CreerEnveloppeSoap()
{
XmlDocument soapEnvelop = new XmlDocument();
string appelMethode = "<" + this.MethodeWeb + " xmlns=" + "\"" + this.UrlHote + this.WCFNomContrat + "\"" + ">";
string strParametres = string.Empty;
foreach (Parametre param in this.Parametres)
{
strParametres = strParametres + "<" + param.Nom + ">" + param.Valeur + "</" + param.Nom + ">";
}
appelMethode = appelMethode + strParametres + "</" + this.MethodeWeb + ">";
StringBuilder sb = new StringBuilder(_enveloppeSoap);
sb.Insert(sb.ToString().IndexOf("</soap12:Body>"), appelMethode);
// Get XML
soapEnvelop.LoadXml(sb.ToString());
return soapEnvelop;
}
我試圖在config文件來更改Web服務地址,它給我的錯誤:
(415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..
所以在CreateWebQuery方法我改變了:
webRequest.ContentType = "application/soap+xml; charset=utf-8"
到
webRequest.ContentType from "text/xml;charset=utf-8"
Web服務調用返回:
The remote server returned an error: (400) Bad Request.
我不熟悉的WCF服務,任何幫助表示讚賞。
謝謝。
