Retrieving Visitors' IP Addresses in Flask for Python
Question:
In a Flask-based Python website that allows users to log in and download files, how can one obtain the IP addresses of visitors upon login for logging purposes?
Answer:
To retrieve the IP addresses of visitors in a Flask application using Python, you can leverage the Werkzeug framework upon which Flask is built. Here's how you can do it:
Code Example:
<code class="python">from flask import request from flask import jsonify @app.route("/get_my_ip", methods=["GET"]) def get_my_ip(): return jsonify({'ip': request.remote_addr}), 200</code>
Explanation:
In this code, we obtain the Request object using the request import from Flask. This object provides access to various request-related information, including the remote_addr attribute, which contains the IP address of the user making the request. We then jsonify the IP address and return it as a response.
Further Information:
For additional insights, refer to the Werkzeug documentation for more details on accessing request attributes and additional request handling methods.
