简介一边听听音乐，一边写写文章。
一、curl上传文件
// POST
curl_easy_setopt(curl, CURLOPT_URL, url); //url地址
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, ResponseData); //对返回的数据进行操作的函数地址
curl_easy_setopt(curl, CURLOPT_WRITEDATA, urlres); //这是write_data的第四个参数值
curl_easy_setopt(curl, CURLOPT_POST, 1); //设置问非0表示本次操作为post
curl_easy_setopt(curl, CURLOPT_HEADER, 0); //1 将响应头信息和相应体一起传给write_data
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1); //设置为非0, 响应头信息location
curl_easy_setopt(curl, CURLOPT_AUTOREFERER, 1); // 以下3个为重定向设置
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1); //返回的头部中有Location(一般直接请求的url没找到)，则继续请求Location对应的数据
curl_easy_setopt(curl, CURLOPT_MAXREDIRS, 3);//查找次数，防止查找太深
curl_easy_setopt(curl, CURLOPT_TIMEOUT, 25);//接收数据时超时设置，如果10秒内数据未接收完，直接退出
curl_easy_setopt(curl, CURLOPT_CONNECTTIMEOUT, 10);//连接超时，这个数值如果设置太短可能导致数据请求不到就断开了
curl_easy_setopt(curl, CURLOPT_NOSIGNAL, 1);
curl_easy_setopt(curl, CURLOPT_FORBID_REUSE, 1);
