推荐答案

http_build_query不创建一个有效的网址，但只格式化您的GET请求的参数数组。
你应该这样做：

http_build_query does not create a valid url but only formats the parameters array for your GET request. You should do something like :

$url = "https://".$_REQUEST['host']."?"."{$query_string}";

在您的示例中，生成的url将是

In your example the resulting url will be

https://www.google.com?host=www.google.com
