php模拟post提交请求，调用接口

 /**
     * 模拟post进行url请求
     * @param string $url
     * @param string $param
     */
    function request_post($url = '', $param = '') {
        if (empty($url) || empty($param)) {
            return false;
        }
        
        $postUrl = $url;
        $curlPost = $param;
        $ch = curl_init();//初始化curl
        curl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定网页
        curl_setopt($ch, CURLOPT_HEADER, 0);//设置header
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上
        curl_setopt($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;
    }

这是方法，

下面是具体的调用案例。

    function testAction(){
        $url = 'http://mobile.jschina.com.cn/jschina/register.php';
        $post_data['appid']       = '10';
        $post_data['appkey']      = 'cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ';
        $post_data['member_name'] = 'zsjs123';
        $post_data['password']    = '123456';
        $post_data['email']    = '[email protected]';
        $o = "";
        foreach ( $post_data as $k => $v ) 
        { 
            $o.= "$k=" . urlencode( $v ). "&" ;
        }
        $post_data = substr($o,0,-1);

        $res = $this->request_post($url, $post_data);       
        print_r($res);

    }

这样就提交请求，并且获取请求结果了。一般返回的结果是json格式的。

这里的post是拼接出来的。

也可以改造成下面的方式。

/**
     * 模拟post进行url请求
     * @param string $url
     * @param array $post_data
     */
    function request_post($url = '', $post_data = array()) {
        if (empty($url) || empty($post_data)) {
            return false;
        }
        
        $o = "";
        foreach ( $post_data as $k => $v ) 
        { 
            $o.= "$k=" . urlencode( $v ). "&" ;
        }
        $post_data = substr($o,0,-1);

        $postUrl = $url;
        $curlPost = $post_data;
        $ch = curl_init();//初始化curl
        curl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定网页
        curl_setopt($ch, CURLOPT_HEADER, 0);//设置header
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上
        curl_setopt($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;
    }

将拼接也封装了起来，这样调用的时候就更简洁了。

        $post_data['member_name'] = 'zsjs124';

        print_r($res);

    }
