Yii 1.1 使用 curl 请求第三方接口 [ 1.1 版本 ]

function curl_post_contents($url, $data = array(), $cookiepath = '',$timeout=10){
    $userAgent = 'Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1)';
    $referer = $url;
    if(!is_array($data) || !$url) return '';
    $post = '';
    foreach($data as $key => $value){
        $post .= $key . '=' . urlencode($value) . '&';
    }
    rtrim($post, '&');
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);                //设置访问的url地址
    curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);        //设置超时
    curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);    //用户访问代理 User-Agent
    curl_setopt($ch, CURLOPT_REFERER, $referer);        //设置 referer
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);        //跟踪301
    curl_setopt($ch, CURLOPT_POST, 1);                  //指定post数据
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post);        //添加变量
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiepath);   //COOKIE的存储路径,返回时保存COOKIE的路径
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        //返回结果
    $content = curl_exec($ch);
    curl_close($ch);
    return $content;
}

 function curl_get_contents($url, $timeout = 5)

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
