怎么在PHP中对CURL扩展类进行封装?针对这个问题,这篇文章详细介绍了相对应的分析和解答,希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
具体如下:
<?php * @编码规范 * @class 类名首字母大写,类名为多个单词, 每个大字首字母大写 eg: class Curl , class CurlPage * @variable 变量名小写, 变量名为多个单词, 每个单词小写,使用下划线_分割 eg: $curl_result * @function 函数名与类名规则相同 eg: function SendRequest * @params 函数形参规则与变量名相同 * @class-variable 成员变量,以下划线结尾,多个单词使用下划线分隔. eg: private $host_name_ */ /** * @要求 * */ class Curl{ /** * @请求的host */ private $host_; /** * @curl 句柄 */ private $ch_; /** * @超时限制时间 */ const time_=5; /** * @请求的设置 */ private $options_; /** * @保存请求头信息 */ private $request_header_; /** * @保存响应头信息 */ private $response_header_; /** * @body_ 用于保存curl请求返回的结果 */ private $body_; /** * @读取cookie */ private $cookie_file_; /** * @写入cookie */ private $cookie_jar_; /** * @todo proxy * @构造函数,初始化CURL回话 */ public function Start($url){ $this->ch_ = curl_init($url); curl_setopt($this->ch_, CURLOPT_HEADER, 1); curl_setopt($this->ch_, CURLOPT_RETURNTRANSFER , 1 ); } /** * @返回响应头 */ public function ResponseHeader($url){ if (!function_exists('http_parse_headers')) { function http_parse_headers ($raw_headers){ $headers = array(); foreach (explode("\n", $raw_headers) as $i => $h) { $h = explode(':', $h, 2); if (isset($h[1])) { if(!isset($headers[$h[0]])) { $headers[$h[0]] = trim($h[1]); } else if(is_array($headers[$h[0]])) { $tmp = array_merge($headers[$h[0]],array(trim($h[1]))); $headers[$h[0]] = $tmp; } else { $tmp = array_merge(array($headers[$h[0]]),array(trim($h[1]))); $headers[$h[0]] = $tmp; } } } return $headers; } } $this->Start($url); curl_setopt($this->ch_, CURLOPT_TIMEOUT, Curl::time_); $this->body_=$this->Execx(); $header_size = curl_getinfo($this->ch_, CURLINFO_HEADER_SIZE); $this->response_header_ = substr($this->body_, $start = 0, $offset = $header_size); $this->response_header_ = http_parse_headers($this->response_header_); print_r($this->response_header_); return $this->Close($this->body_); } /** * @读取cookie */ public function LoadCookie($url,$cookie_file){ $this->Start($url); curl_setopt($this->ch_, CURLOPT_COOKIE, 1); curl_setopt($this->ch_, CURLOPT_COOKIEFILE , $cookie_file); $this->body_=$this->Execx(); return $this->Close($this->body_); } /** * @写入cookie */ public function SaveCookie($url){ $this->Start($url); curl_setopt($this->ch_, CURLOPT_COOKIE, 1); curl_setopt($this->ch_, CURLOPT_COOKIEFILE ,'cookie.txt'); curl_setopt($this->ch_, CURLOPT_COOKIEJAR , 'cookie.txt'); $this->body_=$this->Execx(); return $this->Close($this->body_); } /** * @设置HEADER */ public function SetHeader($headers = null){ if (is_array($headers) && count($headers) > 0) { curl_setopt($this->ch_, CURLOPT_HTTPHEADER, $headers); } } /** * @GET请求 */ public function Get($url, array $params = array()) { if ($params) { if (strpos($url, '?')) { $url .= "&".http_build_query($params); } else { $url .= "?".http_build_query($params); } } $this->Start($url); curl_setopt($this->ch_, CURLOPT_TIMEOUT, Curl::time_); if (strpos($url, 'https') === 0) { curl_setopt($this->ch_, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($this->ch_, CURLOPT_SSL_VERIFYPEER, 0); } $this->body_=$this->Execx(); return $this->Close($this->body_); } /** * @POST请求 */ public function Post($url, array $params = array()) { $this->Start($url); curl_setopt($this->ch_, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($this->ch_, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded")); curl_setopt($this->ch_, CURLOPT_POST, true); curl_setopt($this->ch_, CURLOPT_TIMEOUT, Curl::time_); if ($params) { curl_setopt($this->ch_, CURLOPT_POSTFIELDS, http_build_query($params)); } $this->body_=$this->Execx(); return $this->Close($this->body_); } /** * @tips: google http head 方法 */ public function Head($url, array $params = array()) { $this->Start($url); curl_setopt($this->ch_, CURLOPT_TIMEOUT, Curl::time_); curl_setopt($this->ch_, CURLOPT_RETURNTRANSFER , 0); curl_setOpt($this->ch_,CURLOPT_NOBODY, true); $this->body_=$this->Execx(); return $this->Close($this->body_); } /** * @执行CURL会话 */ public function Execx(){ return curl_exec($this->ch_); } /** * @关闭CURL句柄 */ public function Close($body_){ if ($body_ === false) { echo "CURL Error: " . curl_error($body_); return false; } curl_close($this->ch_); return $body_; } }
