php curl请求http和https

常规curl请求：

$url = 'http://www.jb51.net';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($curl);
curl_close($curl);
var_dump($data);

使用curl请求HTTPS$url = 'https://www.jb51.net';$curl = curl_init();curl_setopt($curl, CURLOPT_URL, $url);curl_setopt($curl, CURLOPT_HEADER, 1);curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);//这个是重点。$data = curl_exec($curl);curl_close($curl);var_dump($data);

当请求https的数据时，会要求证书，这时候，加上下面这两个参数，规避ssl的证书检查curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // https请求 不验证证书和hostscurl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
