可以用curl代替该方法，代码如下：

/**

 * GET 请求  * string $url  */ function http_get($url) {     $oCurl = curl_init();     if (stripos($url, "https://") !== FALSE) {         curl_setopt($oCurl, CURLOPT_SSL_VERIFYPEER, FALSE);         curl_setopt($oCurl, CURLOPT_SSL_VERIFYHOST, FALSE);         curl_setopt($oCurl, CURLOPT_SSLVERSION, 1); //CURL_SSLVERSION_TLSv1     }     curl_setopt($oCurl, CURLOPT_URL, $url);     curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1);     $sContent = curl_exec($oCurl);     $aStatus = curl_getinfo($oCurl);     curl_close($oCurl);     if (intval($aStatus["http_code"]) == 200) {         return $sContent;     } else {         return false;     } }
