先為啥要純手工打造呢，因為對方是用C++做的，我按照他們給出的WSDL實現了一個WebService，結果他們完全不能調用。具體是他們調用的問題還是WSDL定義的問題，不可考了。
悲催的弱勢方……只能我們去配合他們。不提了。
首先用C#調用對方的WebService。
因為對方用的C++實現，添加Web服務引用方式無效……直接添加WSDL的調用對方不認……
只好手工打造，還好C#足夠強大。
HttpWebRequest類可以簡單的實現WebService調用。
首先手工打造SOAP包內容
string soap =
"<soapenv:Envelope xmlns:soapenv=/"http://schemas.xmlsoap.org/soap/envelope//" xmlns:down=/"http://down.wsdl.position.mdd.ailk.com/" xmlns:in=/"http://in.object.down.wsdl.position.mdd.ailk.com/">"
+ "<soapenv:Header/>"
+ "<soapenv:Body>"
+ "<TestFunc>"
+ "<object>Test Message</object>"
+ "</TestFunc>"
+ "</soapenv:Body>"
+ "</soapenv:Envelope>";
構造HttpWebRequest對象
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://localhost:8088/");
request.Method = "POST";
request.ContentType = "text/xml; charset=utf-8";
request.Headers.Add("SOAPAction", "/TestFunc");
byte[] bts = Encoding.UTF8.GetBytes(soap);
發送請求
request.ContentLength = data.Length;
Stream writer = request.GetRequestStream();
writer.Write(data, 0, data.Length);
writer.Close();
獲取返回信息
StreamReader sr = new StreamReader(request.GetResponse().GetResponseStream(), Encoding.UTF8);
String retXml = sr.ReadToEnd();
sr.Close();
之后按照WSDL的定義，解析返回的XML串就好了。
當然手工打造就是累……
如果是標準的WebService，直接一句string str = Serv.TestFunc(“”);
不提了。
C#實現WebService給對方調用
按照我的理解，WebService底層是SOAP，本質上就是一個TCP的短連接。
解決的思路就是用C#來實現一個TCP的服務端，然后手工分析請求內容。
//開始監聽端口
myListener = new TcpListener(IPAddress.Parse(ListenIpAddr), ListenPort);
myListener.Start();
接收連接，并且獲取請求內容
//接受新連接
Socket mySocket = myListener.AcceptSocket();
string sBuffer = "";
Byte[] bReceive = new Byte[2048];
// 接收請求內容
int i = mySocket.Receive(bReceive, bReceive.Length, 0);
sBuffer = Encoding.ASCII.GetString(bReceive);
// 只處理 "POST"請求類型
if (sBuffer.Substring(0, 4) != "POST")
{
return;
}
截取soap:Body部分
string soap = "<?xml version=/"1.0/" encoding=/"utf-8/" ?>/n";
int iStartPos = sBuffer.IndexOf("<soap:Body>", 1);
int iStopPos = sBuffer.IndexOf("</soap:Body>", 1);
if (iStartPos > 0)
{
soap = soap + sBuffer.Substring(iStartPos, iStopPos - iStartPos + 9);
}
分析請求內容這里就略了。
返回消息的構造如下。
首先構造消息體內容
string ret = string.Format(
""
+ "<soapenv:Envelope xmlns:soapenv=/"http://schemas.xmlsoap.org/soap/envelope//" xmlns:down=/"http://down.wsdl.position.mdd.ailk.com/" xmlns:out=/"http://out.object.down.wsdl.position.mdd.ailk.com/">/n"
+ "<soapenv:Header/>/n"
+ "<soapenv:Body>/n"
+ "<TestRsp>/n"
+ "<object ResultCode=/"0/"/>/n"
+ "</TestRsp>/n"
+ "</soapenv:Body>/n"
+ "</soapenv:Envelope>"
);
byte[] bytes = Encoding.ASCII.GetBytes(ret);
構造消息頭部 // 構造頭部
String sMimeType = "text/html";
string sHttpVersion = "HTTP/1.1 ";
String sBuffer = "";
if (sMIMEHeader.Length == 0)
{
sMIMEHeader = "text/html"; // 默認 text/html
}
sBuffer = sBuffer + sHttpVersion + " 200 OK" + "/r/n";
sBuffer = sBuffer + "Server: cx1193719-b/r/n";
sBuffer = sBuffer + "Content-Type: " + sMimeType + "/r/n";
sBuffer = sBuffer + "Accept-Ranges: bytes/r/n";
sBuffer = sBuffer + "Content-Length: " + iTotBytes + "/r/n/r/n";
Byte[] heads = Encoding.ASCII.GetBytes(sBuffer);
然后發送給對方，關閉Socket。mySocket.Send(heads, heads.Length, 0);
mySocket.Send(bytes, bytes.Length, 0);
mySocket.Close();
