php采用file_get_contents代替使用curl实例,curlgetcontents
本文实例讲述了php采用file_get_contents代替使用curl的方法,分享给大家供大家参考。具体实现方法如下:
file_get_contents代替使用curl其实不多见了,但有时你碰到服务器不支持curl时我们可以使用file_get_contents代替使用curl,下面看个例子。
当用尽一切办法发现 服务器真的无法使用curl时。或者curl不支持https时。curl https 出现502时。你又不想重装网站环境的时候,你就改用file_get_contents 代替吧。
curl 经常使用的 curl get curl post
curl get 替代 直接用file_get_contents($url) 就可以了
curl post 替代如下:
复制代码 代码如下:
function Post($url, $post = null) {
$content = http_build_query($post);
$content_length = strlen($content);
$options = array(
'http' => array(
'method' => 'POST',
'header' =>"Content-type: application/x-www-form-urlencoded",
'content' => $post
)
);
return file_get_contents($url, false, stream_context_create($options));
}
希望本文所述对大家的php程序设计有所帮助。
模拟个头部信息
array( 'method'=>"GET", 'header'=>"User-Agent: ".$_SERVER['HTTP_USER_AGENT']."\r\n" ) ); $context = stream_context_create($opts); $url = dynamic.12306.cn/...0$data = file_get_contents($url,null,$context);echo $data;?> 这样就可以了
纯自动录入,还是配合人手动。假如手动就简单多了,无非就是写个正则把页
面的url和标题搞下来。要是纯自动的,你必须写一段程序模拟出来你正常访问
情况,当你到达第一页的时候,是发送的一个POST请求,你需要发送相应参数
和POST请求过去,然后再页面截取相应的需要,当要访问第二版的时候,发送
的是GET请求,这个时候同理要发送参数过去条状,直到第十页。php管网上有
类似的爬虫类,去下个,很方便的

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,
