详解php用curl调用接口方法，get和post两种方式

<?php /**   * 模拟post进行url请求   * @param string $url   * @param array $post_data   */  function request_post($url = '',$ispost=true, $post_data = array()) {    if (empty($url) || empty($post_data)) {      return false;    }        $o = "";    foreach ( $post_data as $k => $v )     {       $o.= "$k=" . urlencode( $v ). "&" ;    }    $post_data = substr($o,0,-1);    $key=md5(base64_encode($post_data));    if($ispost){      $url=$url;    }else{      $url = $url.'?'.$post_data;    }            $curlPost = 'key='.$key;    header("Content-type: text/html; charset=utf-8");    $ch = curl_init();//初始化curl    curl_setopt($ch, CURLOPT_URL,$url);//抓取指定网页    curl_setopt($ch, CURLOPT_HEADER, 0);//设置header    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上    if($ispost){      curl_setopt($ch, CURLOPT_POST, 1);//post提交方式      curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);    }    $data = curl_exec($ch);//运行curl    curl_close($ch);    return $data;  }  ?>

<?php require 'ApiModel.php';function testAction(){    $url = '接口地址';    $post_data['appid']    = '10';    $post_data['appkey']   = 'cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ';    $post_data['member_name'] = 'zsjs124';    $post_data['password']  = '123456';    $post_data['email']  = 'zsjs124@126.com';    //$post_data = array();    $res = request_post($url,$ispost=true,$post_data);        print_r($res);  }testAction();?>

<?php function serverapi(){  $key='57173d6ad842d807443ee0db91fed323';  if($_GET&&$_GET['appkey']=='cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ'||$_POST&&$_POST['key']===$key){    $arr=array('name'=>'huanglu','password'=>'123456');    echo json_encode($arr);  }else{    exit('非法访问！');  }}serverapi();?>
