得到正确的HTTP状态代码的PHP

Question

我的代码给我HTTP状态代码302，当我访问谷歌，但我与Firefox浏览器访问并检查与萤火虫的状态，有状态为200

这里是我的代码：

$ch = curl_init($url); 
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.0) Gecko/20100101 Firefox/25.0"); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); 
curl_exec($ch); 
$info = curl_getinfo($ch); 
curl_close($ch); 

我也试过get_headers，但它给了我301个状态

get_headers($url); 

编辑：结果低于

    'url' => string 'https://www.google.com.cy/?gws_rd=cr&ei=SIeOUo7bGuKH0AWO14CYDQ' (length=62)

Answer 1

啊！谷歌正在通过GEO-IP或类似软件定位你，并将你重定向到你的本地谷歌镜像。

请参见：https://webapps.stackexchange.com/questions/46591/what-does-gws-rd-cr-in-the-url-indicate

所以他们要重定向你的302代码是正确的。

尝试使用网址：https://www.google.com/ncr （ncr代表无国家重定向），并看看你如何去。

Answer 2

您使用Google的哪个网址？

我用你的代码上面，设置：

$url = 'http://www.google.com'; 

并获得在卷曲信息200响应。

的完整代码我正在与测试：

奇怪 - 我使用：

$url = 'http://www.google.com'; 

$ch = curl_init($url); 
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.0) Gecko/20100101 Firefox/25.0"); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); 
curl_exec($ch); 
$info = curl_getinfo($ch); 
curl_close($ch); 

var_dump($info); 

的的var_dump输出I接收返回：
