Postman able to use GET request properly but my program cannot - python-3.x

Question

I have a GET and PUT request built below:
from flask import Flask
from flask_restful import Api, Resource, reqparse
app = Flask(__name__)
api = Api(app)
userStorage =[
{
"id": "1234",
"currentBot": "BestBot"
}
]
class User(Resource):
def get(self, id):
for user in userStorage:
if(id == user["id"]):
return user, 200
return "User not found", 404
def put(self, id):
parser = reqparse.RequestParser()
parser.add_argument("currentBot")
args = parser.parse_args()
for user in userStorage:
if(id == user["id"]):
user["currentBot"] = args["currentBot"]
return user, 200
user = {
"id": id,
"currentBot": args["currentBot"]
}
userStorage.append(user)
return user, 201
def delete(self, id):
global userStorage
userStorage = [user for user in userStorage if user["id"] != id]
return "{} is deleted.".format(id), 200
api.add_resource(User, "/user/<string:id>")
app.run(debug = True, port = 4000)
Postman can properly get a response 200 when I do a simple get request but when I try to do a request through my own program it returns a 404
import requests
payload2Storage = {
"currentBot": "BestBot"
}
headers = {"Content-Type": "application/json"}
params = {
"id": "1234"
}
#response = requests.request("PUT", "http://127.0.0.1:4000/user/", data=payload2Storage, params=params, headers=headers)
response2 = requests.request("GET", "http://127.0.0.1:4000/user/", params=params, headers=headers)
Is there something wrong with my request to get the info from userStorage?

Answer 1

In the client code, changing from 127.0.0.1 to localhost worked for me. Try this:
response2 = requests.request("GET", "http://localhost:4000/user/", params=params, headers=headers)
OR in the server code, bind the server to 127.0.0.1 explicitly via host argument like this:
app.run(debug = True, port = 4000, host='127.0.0.1')
Other error in the code is user["id"] returns a str while id is a int, change the code as below:
def get(self, id):
for user in userStorage:
if(id == int(user["id"])):
return user, 200
return "User not found", 404
