本文实例讲述了php之curl实现http与https请求的方法,分享给大家供大家参考。具体如下:

通常来说,php的curl函数组可以帮助我们把机器伪装成人的行为来抓取网站,下面来分享两个例子,一个是访问http网页,一个访问https网页,一起来看一下。

每次要使用curl的时候,总要查一堆资料。
现在将常用的几句保存下来,省的每次都去谷歌。

常规curl请求:

代码如下:

$url = 'http://www.bitsCN.com';
$curl = curl_init();
curl_setopt($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:

代码如下:

$url = 'https://www.bitsCN.com';
$curl = curl_init();
curl_setopt($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);

注意

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

代码如下:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // https请求 不验证证书和hosts
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

希望本文所述对大家的PHP程序设计有所帮助。
