今天无聊,用php封装了一套比较简单的http请求类
细节方面可以再优化
class Creeper { public $url; public $header; public $text; public $responseHeader; public function __construct($url){ $this->url = $url; $this->header = "Accept-language: *\r\n" . "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36\r\n" ; } public function get(){ $a = array( ‘http‘ => array( ‘method‘=> "GET", ‘header‘=> $this->header ), ‘ssl‘ => array( # 取消ssl验证 "verify_peer" => false, "verify_peer_name" => false ) ); $context = stream_context_create($a); // 创建上下文 $url = $this->url; $this->text = file_get_contents($url, false, $context); // 进行访问 $this->responseHeader = $http_response_header; //var_dump($http_response_header); } public function post($data){ $postdata = urlencode($data); $a = array( ‘http‘=>array( ‘method‘=> "POST", ‘header‘=> $this->header. "Content-Type: application/x-www-urlencoded\r\n", ‘content‘ => $postdata ) ); $context = stream_context_create($a); // 创建上下文 $url = $this->url; $this->text = file_get_contents($url, false, $context); // 进行访问 $this->responseHeader = $http_response_header; //var_dump($http_response_header); } }
基本上使用起来也还是挺方便的:
$creeper = new Creeper(‘http://www.xxxxx.com‘); $creeper->get(); preg_match_all("/href=\"(.*?)\" target=/", $creeper->text, $links); $links = $links[1];
over.
