I just finished programming a dog photo program, and after a few issues it works fine. I decided to make a modified version that uses a different api to give cat images instead. It took a second to figure out but after changing the format, I get this error: urllib.error.HTTPError: HTTP Error 403: Forbidden
This error is consistent and happens every single time.
Here’s my entire code, since none of these answers seemed to help.
import tkinter, urllib.request, json
from PIL import Image, ImageTk
#Create the main window
main = tkinter.Tk()
main.geometry('550x600+800+300')
main.title('Dogs')
#This is the list of dog image urls
urllist = []
#This is the list of dog images
doglist = []
#This is a pointer to the image in the list, which is used as the image in the label
dognumber = 0
#Set W and H to the max width and height we want for the images
W, H = 500, 460
#Resize the image to the max width and height
def resize_image(img):
ratio = min(W/img.width, H/img.height)
return img.resize((int(img.width*ratio), int(img.height*ratio)), Image.ANTIALIAS)
#Change dog number by -1 to go back a dog, then set the image to the new dog
def last_image():
global doglist, dognumber
#This is pretty self explanatory
dognumber -= 1
#If the dog number is less than 0, set it to 0 so there's no negative indexing in dog list
if dognumber < 0:
dognumber = 0
#Set the image to the new dog
l.config(image=doglist[dognumber])
def fetch_image():
global doglist, dognumber, urllist
try:
#If the dog number is less than the length of the list, simply increment it by 1 and set the image to the new dog. This allows you to go back a dog, and then go forward again, instead of generating a new dog every time
dognumber += 1
l.config(image=doglist[dognumber])
except IndexError:
#Even if we are on the last dog on the list, that try script will add one to the dog number, so we need to subtract one to get the correct index
dognumber -= 1
#Get the actual image of the dog we want

dogapi.add_header("x-api-key", "blahblahblah12312")

def preloaddogs():
global doglist, dognumber, urllist
for _ in range(5):
#This does the same thing as fetch_image, but it doesn't increment the dog number so you dont end up on the last dog, and it sets the image shown to the first dog

dogjson = dogapi.read()

I tried adding an api key, and I still get the same error. Then tried adding it to the header, same story.
Since none of these answers are working, I added my entire code. Hopefully this helps.

Answer
The “thecatapi” needs an API Key and it seems like you aren’t providing one and that’s the reason you’re getting the 403 error
Try adding an API Key as Request Header
You can get one on the thecatapi website
import requests
from PIL import Image
from io import BytesIO
token = "token"
def getRandomCat():
url = "https://api.thecatapi.com/v1/images/search"
response = requests.get(url, params={"x-api-key": token})
return response.json()[0]["url"]
if __name__ == '__main__':
# get url of image
url = getRandomCat()
# get content from the url with the image
response = requests.get(url)
# convert and open Image (conversion with io)
image = Image.open(BytesIO(response.content))
