Flask 에서 사용 할 경우

 

from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route("/geolocation", methods=["POST"])
def geolocation():
    ip = request.remote_addr
    result = get_geolocation(ip)
    return jsonify(result)

if __name__ == "__main__":
    app.run(debug=True)

 

필요한 라이브러리
