php模擬post提交請求，curl調(diào)用接口

/**
     * 模擬post進(jìn)行url請求
     * @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,$postUrl);//抓取指定網(wǎng)頁
        curl_setopt($ch, CURLOPT_HEADER, 0);//設(shè)置header
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求結(jié)果為字符串且輸出到屏幕上
        curl_setopt($ch, CURLOPT_POST, 1);//post提交方式
        curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
        $data = curl_exec($ch);//運(yùn)行curl
        curl_close($ch);

        return $data;
    }

將拼接也封裝了起來，這樣調(diào)用的時(shí)候就更簡潔了。

function testAction(){
        $url = 'http://mobile.jschina.com.cn/jschina/register.php';
        $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 = $this->request_post($url, $post_data);       
        print_r($res);

    }
