Cant seem to find any info on this, but was wondering if there is any way to detect if a user is on a wifi connection, specifically public wifi, using javascript, or php?

推荐答案

不，没有，IPv4和HTTP传输中没有任何内容甚至提示使用何种连接，除了底层协议本身，通常是IPv4和HTTP。

No, there isn't, there is nothing in the IPv4 nor the HTTP transport that even hints at what kind of connection is used, except for the underlying protocol itself, which is usually IPv4 and HTTP.

不，IPv6也不包含此信息。

No, IPv6 doesn't include this information either.
