怎样做网站教程/服装市场调研报告
症状：php curl调用https出错
排查方法：在命令行中使用curl调用试试。
原因：服务器所在机房无法验证SSL证书。
解决办法：跳过SSL证书检查。
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
症状：php curl调用curl_exec返回bool(false)，命令行curl调用正常。
排查方法：
var_dump(curl_error($ch));
返回：
string(23) "Empty reply from server"
再排查：
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false);
返回：
HTTP/1.1 100 Continue
Connection: close
原因：php curl接收到HTTP 100就结束了，应该继续接收HTTP 200
解决方案：
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));
