也就是说服务端的代码都是涉及到运算等方面的,而客户端代码只是呈现出服务端代码运算的结果,现在全球服务器里面的代码跟客户端的代码几乎都不是一样的
要实现客户端与服务器端的通讯,需要两部分C++的程序:服务器端程序代码和客户端代码。
首先是服务器端程序代码:
#include <WinSock2.h>
#include <stdio.h>
#include <stdlib.h>
#pragma comment(lib, "ws2_32.lib")
void main()
{
WSADATA wsaData
int port = 5099
char buf[] = "Server: hello, I am a server....."
if(WSAStartup(MAKEWORD(2, 2), &wsaData) != 0)
{
printf("Failed to load Winsock")
return
}
//创建用于监听的套接字
SOCKET sockSrv = socket(AF_INET, SOCK_STREAM, 0)
SOCKADDR_IN addrSrv
addrSrv.sin_family = AF_INET
addrSrv.sin_port = htons(port)//1024以上的端口号
addrSrv.sin_addr.S_un.S_addr = htonl(INADDR_ANY)
int retVal = bind(sockSrv, (LPSOCKADDR)&addrSrv, sizeof(SOCKADDR_IN))
if(retVal == SOCKET_ERROR){
printf("Failed bind:%d\n", WSAGetLastError())
return
}
if(listen(sockSrv,10) ==SOCKET_ERROR){
printf("Listen failed:%d", WSAGetLastError())
return
}
SOCKADDR_IN addrClient
int len = sizeof(SOCKADDR)
while(1)
{
//等待客户请求到来
SOCKET sockConn = accept(sockSrv, (SOCKADDR *) &addrClient, &len)
if(sockConn == SOCKET_ERROR){
printf("Accept failed:%d", WSAGetLastError())
break
}
printf("Accept client IP:[%s]\n", inet_ntoa(addrClient.sin_addr))
//发送数据
int iSend = send(sockConn, buf, sizeof(buf) , 0)
if(iSend == SOCKET_ERROR){
printf("send failed")
break
}
char recvBuf[100]
memset(recvBuf, 0, sizeof(recvBuf))
// //接收数据
recv(sockConn, recvBuf, sizeof(recvBuf), 0)
printf("%s\n", recvBuf)
closesocket(sockConn)
}
closesocket(sockSrv)
WSACleanup()
system("pause")
}
接下来是客户端代码:
#include <WinSock2.h>#include <stdio.h>
#pragma comment(lib, "ws2_32.lib")
void main()
{
//加载套接字
WSADATA wsaData
char buff[1024]
memset(buff, 0, sizeof(buff))
if(WSAStartup(MAKEWORD(2, 2), &wsaData) != 0)
{
printf("Failed to load Winsock")
return
}
SOCKADDR_IN addrSrv
addrSrv.sin_family = AF_INET
addrSrv.sin_port = htons(5099)
addrSrv.sin_addr.S_un.S_addr = inet_addr("127.0.0.1")
//创建套接字
SOCKET sockClient = socket(AF_INET, SOCK_STREAM, 0)
if(SOCKET_ERROR == sockClient){
printf("Socket() error:%d", WSAGetLastError())
return
}
//向服务器发出连接请求
if(connect(sockClient, (struct sockaddr*)&addrSrv, sizeof(addrSrv)) == INVALID_SOCKET){
printf("Connect failed:%d", WSAGetLastError())
return
}else
{
//接收数据
recv(sockClient, buff, sizeof(buff), 0)
printf("%s\n", buff)
}
//发送数据
char buff = "hello, this is a Client...."
send(sockClient, buff, sizeof(buff), 0)
//关闭套接字
closesocket(sockClient)
WSACleanup()
}
<soapenv:Header/><soapenv:Body>
<api:getEmp>
<shopId>string</shopId>
</api:getEmp>
</soapenv:Body>
</soapenv:Envelope>
这个时SOAP协议的标准报文格式,客户端只要发送这样的报文给支持SOAP协议的webservice服务器即可成功调用web service服务
服务端:部署服务只需要自己定义服务的接口和实现类,并用@webservice注解,通过endPoint类直接发布即可
