PHP 傳輸會話curl函數的實例詳解
前言：
接手公司項目PC端負責人的重擔，責任擔當重大；從需求分析，畫流程圖，建表，編碼，測試修bug，上線維護等我一個光桿司令一人完成(當然還有一個技術不錯的前端配合,感謝主管的幫助)，雖然累點加班多點但感覺還行吧，公司都是一個鳥樣。
閑話不多說了，因為項目中經常需要調取java那邊的接口，既然涉及到請求接口那就有了http的請求方式，PHP常見的是GET/POST兩種當然還有其他的比如put等，java那邊經常用到GET/POST/PUT/DELETE等方式，請求接口當然要用到curl的相關函數了，都是看文檔調試的希望大家都看文檔，下面是我封裝好的相關函數等(大概總結下，已調通)：
示例代碼：
private $serverhost = "https://demo.xxx.cn"; //測試 /** * 請求接口封裝 get/post/put/delete等 * access public * @param string $url 接口地址 * @param string $params 參數 * @param string $type 類型 get/post/put/delete * @return bool/array */ public function getcurldata($url,$params,$type="get"){ $url = $this->serverhost.$url; $response = array(); if($type == 'get'){ //get請求 //請求頭可以加其他設置 $headers = array( 'Content-type: application/json;charset=UTF-8', ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $response = curl_exec($ch); }elseif ($type == 'post'){ //post請求 $headers = array( 'Content-type: application/json;charset=UTF-8', ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_POST, true); //注意這幾行 curl_setopt($ch, CURLOPT_POSTFIELDS, $params); //注意這幾行 //curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $response = curl_exec($ch); }elseif ($type == 'put'){ //put請求 $headers = array( 'Content-type: application/json;charset=UTF-8', ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_PUT, true); //注意這幾行 curl_setopt($ch, CURLOPT_POSTFIELDS, $params); //curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $response = curl_exec($ch); } return $response; } //如何調用上面代碼 //get方式 /** * 查詢我創建過的班級 * @param string $url 接口地址 * @param string $params 參數 * @param string $type 類型 get * @return array */ public function mycreateclass($userid){ $url = "/xxx/xxxx/xxxx/".$userid; //請求地址拼接 $response = $this->getcurldata($url,array(),"get"); $createdclass = json_decode($response, true); //返回json格式數據 return $createdclass; } /** post方式請求 * 用戶登錄判斷 * access public * @param string $username 用戶名 * @param string $password 密碼 * @return bool */ public function getlogin($username,$password) { //要post的數據 $params = array( "username" => $username, "password" => $password ); $params = json_encode($params, 64|256); $uri = "/xxx/xxx/login"; $response = $this->getcurldata($uri,$params,"post"); $result = json_decode($response, true); return $result ; } /*身份轉換--put 請求 */ public function changeuserole($token){ //要put的數據 $params = array(); $params = json_encode($params, 64|256); $uri = "/xxx/xxx/xxx/".$token."/"; $response = $this->getcurldata($uri,$params,"put"); $result = json_decode($response, true); //dump($result);die; return $result; } //還有一個delete方式 大家自己參考文檔調試下吧上面3個請求方式都是單次請求(即請求一次)***************PHP自帶函數curl_multi_get_contents函數(thinkphp自帶此函數，可以微調下)： /** * 批量發起請求 已調通 * curl multi POST數據 * */ public function curl_multi_get_contents($url=array(), $param = array(), $timeout=1000){ $userAgent = 'Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1)'; $headers = array( 'Content-type: application/json;charset=UTF-8', ); $curl_array=array(); $mh = curl_multi_init(); foreach($url as $uk=>$uv){ $curl_array[$uk] = curl_init(); } unset($uk,$uv); foreach($url as $uk=>$uv) { $options = array( CURLOPT_URL => $uv, CURLOPT_TIMEOUT => $timeout, CURLOPT_RETURNTRANSFER => true, CURLOPT_DNS_CACHE_TIMEOUT => 86400, CURLOPT_DNS_USE_GLOBAL_CACHE => true, CURLOPT_SSL_VERIFYPEER => 0, CURLOPT_HEADER => false, CURLOPT_USERAGENT => 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)', CURLOPT_HTTPHEADER => $headers, ); if (isset($param[$uk])) { foreach ($param[$uk] as $_k => $_v) { //$options[$_k] = $_v; $optionsparam[$_k] = $_v; $options[CURLOPT_POSTFIELDS] = json_encode($optionsparam, 64|256); } } curl_setopt_array($curl_array[$uk], $options); curl_multi_add_handle($mh, $curl_array[$uk]); unset($options); } unset($uk,$uv); $running = NULL; do { curl_multi_exec($mh,$running); } while($running > 0); $res = array(); foreach($url as $uk=>$uv){ $res[$uk] = curl_multi_getcontent($curl_array[$uk]); } unset($uk,$uv); foreach($url as $uk=>$uv){ curl_multi_remove_handle($mh, $curl_array[$uk]); } unset($url,$curl_array,$uk,$uv); curl_multi_close($mh); return $res; } //如何調用--批量發起請求 //批量請求加入班級 public function batchjoinclass($token,$batchjoinclass){ $urlarr = $param = $returndata = array(); $param = $batchjoinclass; //二維數組 格式如下 /* $param[1]['name'] = '班級新1'; $param[1]['iamge'] = 'xxx11.png'; $param[1]['iamgeType'] = 'CUSTOM'; $param[2]['name'] = '班級新2'; $param[2]['iamge'] = 'xxx.png'; $param[2]['iamgeType'] = 'CUSTOM'; */ //獲取請求url foreach($batchjoinclass as $key=>$val){ $urlarr[$key] = $this->serverhost."/xxx/xxxx/xxxx/".$token; } $res = $this->curl_multi_get_contents($urlarr,$param); //格式化返回數據 foreach($res as $key=>$val){ $returndata[$key] = json_decode($val,true); } return $returndata; } 如有疑問請留言或者到本站社區交流討論，感謝閱讀，希望能幫助到大家，謝謝大家對本站的支持！
