php之curl实现http与https请求的方法
这篇文章主要介绍了php之curl实现http与https请求的方法,分别讲述了PHP访问http网页与访问https网页的实例,以及相关的注意事项,需要的朋友可以参考下
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:
复制代码 代码如下:
$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:
复制代码 代码如下:
$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);
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
复制代码 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。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
