php程序员开发程序过程中,经常需要调用其他的接口。php为我们提供了一系列函数。curl系列函数。下面就这一些列函数的用法加以说明,以备自己和他人查阅。
demo.php
<?php function curl_get($url,$headerArr=‘‘,$cookie=‘‘){ $ch = curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 3); curl_setopt($ch, CURLOPT_TIMEOUT, 10);//10秒超时 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); if($headerArr){ curl_setopt($ch, CURLOPT_HTTPHEADER , $headerArr); } if($cookie){ curl_setopt($ch, CURLOPT_COOKIE, $cookie); } $data = curl_exec($ch); curl_close($ch); return $data; } // 调用实例 $url = "http://192.168.10.26:8801/2/sub-system/user"; $cookie = "token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VySWQiOjIyM30.Y25kn6rLQCttGrsEuf4taTqBvKD9oMaZVOEb2L0Ig7U"; $results=curl_get($url,‘‘,$cookie); $results=json_decode($results,true); if($results[‘code‘]==0){ return $results[‘data‘]; } return ""; function curl_post($url,$postData,$headerArr=‘‘,$cookie=‘‘){ if(is_array($postData)){ $postData=http_build_query($postData); //生成 URL-encode 之后的请求字符串 } $ch = curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 3); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_POST, 1);//10秒超时 curl_setopt($ch, CURLOPT_POSTFIELDS,$postData); if($headerArr){ curl_setopt($ch, CURLOPT_HTTPHEADER , $headerArr); } if($cookie){ curl_setopt($ch, CURLOPT_COOKIE, $cookie); } $data = curl_exec($ch); curl_close($ch); return $data; } // 调用实例 $url = "http://devwallet.100msh.com/walletadmin/api/wallet/"; $data = array(‘time‘=>date(‘Y-m-d H:i:s‘,strtotime(‘-1 day‘))); $des = new Des(‘@Wt^2)V#‘); // php,java等通用的des加密解密算法类 $data = $des->encrypt(json_encode($data)); $headerArr=array( ‘Content-type:text/html‘, ); $results = curl_post($url,$data,$headerArr); $results = json_decode($results,true); if($results[‘code‘]==0){ return $results[‘data‘]; } return ""; ?>
