php用curl调用接口方法，get和post两种方式

首先是客户端执行方法ApiModel.php：

<?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;
    }
    ?>

客户端调用方法，可以在此配置基本信息api.php：

<?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();
?>

服务器的接口函数test.php：

<?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();
?>
