 php curl常见错误:SSL错误、bool(false)

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:'));
Copy after login
