示例1: doUpload
// POST 方式且满足：
// Content-Type: multipart/form-data; boundary=xxx
bool doUpload(HttpServletRequest& req, HttpServletResponse& res)
{
// 先获得 Content-Type 对应的 http_ctype 对象
http_mime* mime = req.getHttpMime();
if (mime == NULL)
{
logger_error("http_mime null");
return false;
}
// 获得数据体的长度
long long int len = req.getContentLength();
if (len <= 0)
{
logger_error("body empty");
return false;
}
// 获得输入流
istream& in = req.getInputStream();
