我用抓包工具分析测试，发现用浏览器表单提交和c程序发送的数据一模一样，而浏览器能接收到应答，而c程序确一直阻塞于套接字的读过程，根本没有应答，代码如下：
#include "stdio.h"
#include "stdlib.h"
#include "winsock2.h"
#pragma comment(lib,"ws2_32.lib")
int main(int argc, char* argv[])
{
SOCKET hsocket;
SOCKADDR_IN saServer;
WSADATA wsadata;
LPHOSTENT lphostent;
int nRet;
char* host_name="**.**.**.**";
char* reqHead="GET /test/proc8.jsp?cardno=9175880000000051&action=3 HTTP/1.1\r\n"
"Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/msword, application/vnd.ms-excel, application/vnd.ms-powerpoint, */*\r\n"

// 初始化套接字
if(WSAStartup(MAKEWORD(2,2),&wsadata))
printf("初始化SOCKET出错！");
lphostent=gethostbyname(host_name);
if(lphostent==NULL)
printf("lphostent为空！");
hsocket = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
saServer.sin_family = AF_INET;
saServer.sin_port = htons(8088);
saServer.sin_addr = *((LPIN_ADDR)*lphostent->h_addr_list);
// 利用SOCKET连接 FineReader
nRet = connect(hsocket,(LPSOCKADDR)&saServer,sizeof(SOCKADDR_IN));
if(nRet == SOCKET_ERROR)
{
printf("建立连接时出错！");
closesocket(hsocket);
return 0;
}
// 利用SOCKET发送
nRet = send(hsocket,reqHead,strlen(reqHead),0);
if(nRet==SOCKET_ERROR)
{
printf("发送数据包时出错！");
