Anvil HTTP Get Method "Headers Not Defined

Anvil Q&A
#1

What I’m trying to do:
Hi,

I am trying to get the results of my API when the button is clicked. But each time I try the terminal shows an error " NameError: name 'headers' is not defined". I’ve tried testing my code on visual studio and it works perfectly but not for anvil.

Code Sample:

from anvil import *
import anvil.tables as tables
import anvil.tables.query as q
from anvil.tables import app_tables
import anvil.http
import json

class Form1(Form1Template):  #anvil.http.request

  def __init__(self, **properties):
    # Set Form properties and Data Bindings.
    self.init_components(**properties)

    # Any code you write here will run when the form opens.

  def button_1_click(self, **event_args):
    url = "https://breachdirectory.p.rapidapi.com/"

    querystring = {"func":"auto","term":self.UserData}
    response = anvil.http.request(url, method="GET", headers=headers, params=querystring)
    data = str(json.loads(response.text)) #12 char position 
    p = data[12]
    if p == 'T':
      self.output = "Your Data Has Been Leaked!"
    else: 
      self.output = "Your Data Has Not Been Leaked"
    
    
    """This method is called when the button is clicked"""
    pass

I’m still learning Python, but with the error it seems like your issue is here:

response = anvil.http.request(url, method="GET", headers=headers, params=querystring)

I don’t see a headers variable in your code so you are defining a header in the request with no data. If a header is not needed then removed headers=headers or use a header and see if that works.
