Amazon Elastic Beanstalk - get visitor IP address (python)

问题

My application is developed in python and the bottle framework. I am using following code snippet to get IP address of visitors to the page:

user_ip = bottle.request.environ['REMOTE_ADDR']

It works fine on my local machine, however, after deployment to the AWS Beanstalk instance, I think I am getting the load balancer IP, as the user_ip reads something like 10.48.95.234.

Is my thinking correct? If so, is there any way to obtain real visitor's ip address?

回答1:

You are correct that the REMOTE_ADDR value you are getting is for the ELB.

You would typically need to look for the X-Forwarded-For header in the request. The ELB will insert this header to let you know the end client IP address.

回答2:

There is also a bottle-specific version that helps out in this case:

user_ip = bottle.request.remote_addr

This automagically does the processing and gets user's address. See documentation or source code for more details.

回答3:

This works for my ELB:

from bottle import route, run, request

@route('/hello')
def hello():
    return "Hello, {}".format(request.remote_route)

run(host="0.0.0.0", port=8000, server='twisted')
