在 VC 中用 WinInet 的 CInternetSession::OpenURL(url),得到一个 CFile,读取其中的内容即可，详细代码如下
#include
#include
int main(int argc, char* argv[])
{
CInternetSession session("HttpClient");
char * url = " http://www.imobile.com.cn/simcard.php?simcard=1392658";
CHttpFile* pfile = (CHttpFile *)session.OpenURL(url);
DWORD dwStatusCode;
pfile -> QueryInfoStatusCode(dwStatusCode);
if(dwStatusCode == HTTP_STATUS_OK)
{
CString content;
CString data;
while (pfile -> ReadString(data))
{
content += data + "rn";
}
content.TrimRight();
printf(" %sn " ,(LPCTSTR)content);
}
pfile -> Close();
delete pfile;
session.Close();
return 0 ;
}

while (pfile -> ReadString(data))
{

}
content.TrimRight();
printf(" %sn " ,(LPCTSTR)content);
}
pfile -> Close();
delete pfile;
session.Close();
return 0 ;
}
其他如不从缓存中读取内容及如何使用代理连接现在就不说了，可以参考下面的链接，或者下次补上。另外不妨看看 Java 是如何读取 URL 内容的，更简单
GetMethod httpMethod = new GetMethod("http://unmi.blogcn.com");
int statusCode = new HttpClient().executeMethod(httpMethod);
if(statusCode == HttpStatus.SC_OK)
{
System.out.println(httpMethod.getResponseBodyAsString());
}
httpMethod.releaseConnection();
GetMethod httpMethod = new GetMethod("http://unmi.blogcn.com");
int statusCode = new HttpClient().executeMethod(httpMethod);
if(statusCode == HttpStatus.SC_OK)
{
System.out.println(httpMethod.getResponseBodyAsString());
}
httpMethod.releaseConnection();
内容取过来之后，总是希望从中拣出需要的数据，可惜 VC6 中没有自己的正则表达式库，所以下一步要学用 boost 的正则表达式库。
