先為啥要純手工打造呢，因?yàn)閷?duì)方是用C++做的，我按照他們給出的WSDL實(shí)現(xiàn)了一個(gè)WebService，結(jié)果他們完全不能調(diào)用。具體是他們調(diào)用的問題還是WSDL定義的問題，不可考了。
悲催的弱勢(shì)方……只能我們?nèi)ヅ浜纤麄儭２惶崃恕?/P>
首先用C#調(diào)用對(duì)方的WebService。
因?yàn)閷?duì)方用的C++實(shí)現(xiàn)，添加Web服務(wù)引用方式無效……直接添加WSDL的調(diào)用對(duì)方不認(rèn)……
只好手工打造，還好C#足夠強(qiáng)大。
HttpWebRequest類可以簡(jiǎn)單的實(shí)現(xiàn)WebService調(diào)用。
首先手工打造SOAP包內(nèi)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(gòu)造HttpWebRequest對(duì)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(fā)送請(qǐng)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(dāng)然手工打造就是累……
如果是標(biāo)準(zhǔn)的WebService，直接一句string str = Serv.TestFunc(“”);
不提了。
C#實(shí)現(xiàn)WebService給對(duì)方調(diào)用
按照我的理解，WebService底層是SOAP，本質(zhì)上就是一個(gè)TCP的短連接。
解決的思路就是用C#來實(shí)現(xiàn)一個(gè)TCP的服務(wù)端，然后手工分析請(qǐng)求內(nèi)容。
//開始監(jiān)聽端口
myListener = new TcpListener(IPAddress.Parse(ListenIpAddr), ListenPort);
myListener.Start();
接收連接，并且獲取請(qǐng)求內(nèi)容
//接受新連接
Socket mySocket = myListener.AcceptSocket();
string sBuffer = "";
Byte[] bReceive = new Byte[2048];
// 接收請(qǐng)求內(nèi)容
int i = mySocket.Receive(bReceive, bReceive.Length, 0);
sBuffer = Encoding.ASCII.GetString(bReceive);
// 只處理 "POST"請(qǐng)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(qǐng)求內(nèi)容這里就略了。
返回消息的構(gòu)造如下。
首先構(gòu)造消息體內(nèi)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(gòu)造消息頭部 // 構(gòu)造頭部
String sMimeType = "text/html";
string sHttpVersion = "HTTP/1.1 ";
String sBuffer = "";
if (sMIMEHeader.Length == 0)
{
sMIMEHeader = "text/html"; // 默認(rèn) 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(fā)送給對(duì)方，關(guān)閉Socket。mySocket.Send(heads, heads.Length, 0);
mySocket.Send(bytes, bytes.Length, 0);
mySocket.Close();
