除非http_user_agent = xxx，否则客户希望我阻止对该页面的访问.

A client wants me to block access to a page unless the http_user_agent = xxx.

有没有办法做到这一点?我在想if else或if not函数，但这似乎不存在.

Is there a way to do this? I was thinking of an if else or if not function but this doesn't seem to exist.

如果我想阻止用户代理，可以执行以下操作，但是有一种方法只能允许该用户代理吗?

If I wanted to block a user agent I could do the below but is there a way to only allow that user agent?

if ($http_user_agent ~* (xxx) ) { return 403; }

推荐答案

使用!~*运算符，它是~*的否定版本.

Use the !~* operator which is the negated version of ~*.
