When saving data to Firebase database with a Firebase cloud function, I'd like to also write the IP address where the request comes from.
使用Firebase云功能将数据保存到Firebase数据库时，我还想写出请求来源的IP地址。
However, req.connection.remoteAddress always returns ::ffff:0.0.0.0. Is there a way to get the actual IP address of the client that makes the request?

The IP address seems to be available in req.headers["x-forwarded-for"]. I didn't find official information on this in the documentation, though.
IP地址似乎在req.headers [“x-forwarded-for”]中可用。但是，我没有在文档中找到关于此的官方信息。
Also please note that if the client itself sends e.g. X-Forwarded-For: 1.2.3.4, the values are concatenated:
另请注意，如果客户自己发送例如X-Forwarded-For：1.2.3.4，值连接在一起：
"x-forwarded-for":"1.2.3.4, actual-client-ip-as-seen-by-google"

If you are looking for the client ip thru firebase hosting you should use the header fastly-client-ip there will be the real client ip.
如果你正在寻找客户端ip通过firebase托管你应该使用标头fastly-client-ip将有真正的客户端IP。
