Http in - remote address

[Vlad Livshitz]

Hi,

How to get remote data from "http in" node?

I created a such node and redirected the request related data to console - i did not find any relevant IP there,

So, how can i collect statistic log?

Thanks

Vlad msg.req.ip

NodeRed uses Express so you can access Express Request Object to get at parameters

Lawrence,

thank you for this response.

Yes, i can see an IP  address in such way!

But, I still don't understand,  when i printed a whole msg to console, why I was not able find the IP?

And another issue, i'm running my app on IBM BlueMix. So all addresses that I get are address of SoftLayer. I.e. it seems that request is redirected... Here, i guess, I can't do anything...

Thanks!

Vlad,

how are you printing the whole message to the console? The debug node, by default, only displays the value of msg.payload. 

As for running the Bluemix, you are seeing the IP address of the proxy that sits in front of VMs running the actual applications.

By inspection, I think the proxy sets the http header "x-client-ip" to the IP address of the original requesting client:

    var ip = msg.req.get("x-client-ip")

Vlad you might also want to look at this req.ips

When "trust proxy" is true, parse the "X-Forwarded-For" ip address list and return an array. Otherwise, an empty array is returned.

For example, if the value were "client, proxy1, proxy2", you would receive the array ["client", "proxy1", "proxy2"], where "proxy2" is the furthest down-stream.

Thank you,

The assignment var ip = msg.req.get("x-client-ip") solves my problem!

Thanks, i tried, but i obtained empty list.

Now i use

var ip = msg.req.get("x-client-ip")

from previous post to get an IP.

Thank you

P.S. I need IP to apply some security polices for my POC.
In the future i would like to protect the webpage with password. Do you have a tip how to do it?

Thank you
