因为你域名 HTTP变成了HTTPS了在 curl_get方法中写一个 

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 就OK了

public static function curl_getth($url){
// die(6);
$testurl = $url;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $testurl);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);                            //  <-------------------------
//參数为1表示数据传输。为0表示直接输出显示。
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//參数为0表示不带头文件，为1表示带头文件
curl_setopt($ch, CURLOPT_HEADER,0);
$output = curl_exec($ch);
curl_close($ch);
return $output;
}
