What does Flask return when parameters are empty

Solution

@app.route("/test",methods=["GET"]) 
def test():
  emptyvalues = ["", "''", " ", "' '", None, '""', '" "']
  data = request.args
  if "ip" in data and data["ip"] not in emptyvalues:
    hasIP = True
  else:
    hasIP = False
  if "port" in data and data["port"] not in emptyvalues:
    hasPort = True
  else:
    hasPort = False

  print(hasIP, hasPort)
  print(data)
  return 'hello'

/test?ip=123&port=&domain=&formated_domain=&asn=&isp=&orginization=&tag=&product=&city=i&country=u&email=&tel=

True
False
ImmutableMultiDict([('ip', '123'), ('port', ''), ('domain', ''), ('formated_domain', ''), ('asn', ''), ('isp', ''), ('orginization', ''), ('tag', ''), ('product', ''), ('city', 'i'), ('country', 'u'), ('email', ''), ('tel', '')])
