################################GET方法请求######################
一、culr函数
/*
 * curl get 方式获取远程内容
 * @param $url string 远程URL
 * @param $timeout int 
 * @return string
 */
function curl_get($url,$timeout){
    $ch = curl_init();
    curl_setopt ($ch, CURLOPT_URL, $url);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt ($ch, CURLOPT_TIMEOUT, $timeout);
    $file_contents = curl_exec($ch);
    curl_close($ch);
    return $file_contents;
}
二、通过file_get_contents()
return file_get_contents($url); 

/*
    * 对https的URL发送请求
    */
   private function curl_for_https($url){
       $ch = curl_init();
       curl_setopt($ch, CURLOPT_URL,$url);
       curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
       curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
       //并且页面直接输出后 就不向下执行了
       curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
       $result = curl_exec($ch);
       curl_close($ch);
       return $result;
   }
