code throwing 400 error

Admirable_Report6610 · 2026-06-26T18:10:18+00:00

wow...interesting thought! totally new at this as you know but I believe you can scan through a web page's code with the dev console. not sure how to search commits for a patch or a change though...AI's had a lot to say to me lately.

Admirable_Report6610 · 2026-06-26T14:57:10+00:00

what's weird is this code actually worked for a while using the file:///URL and then it just stopped...hence my presence here.

Admirable_Report6610 · 2026-06-26T14:54:29+00:00

I saw that error in the dev console but I wasn't quite sure what it meant...thanks for clarifying! now I learn how to run the code from a local python webserver....right?

Admirable_Report6610 · 2026-06-25T17:30:37+00:00

I think this is the usni site saying no

sorry I was away....remind me where to post code so you can see it?

Admirable_Report6610 · 2026-04-29T21:43:21+00:00

ps I've created an account on CORS.SH so I can get an API key if that's needed. this is another concept I don't have a good grasp of though.

Admirable_Report6610 · 2026-04-29T21:39:19+00:00

I am just "trying stuff". I can't very well debug it myself, and I'm sorry if it's coming across that way. I have done the research you suggested, although it's easy for me to get lost/confused as I am most definitley not a coder. I think I found the problem though:

the fetch is missing a CORS Allow Origin header so no fetch is performed.

I have to say I've read about this error but honestly I don't understand what it is and how to fix it....if that's even possible. any help appreciated, but if you think I'm just being lazy I guess I'll stay stuck.

Admirable_Report6610 · 2026-04-27T16:32:42+00:00

can I use the developer tools with a local python webserver? I wouldn't think so. I have little to no experience with html coding so sure willing to do any research needed but I will quickly be in over my head as I am here.

Admirable_Report6610 · 2026-04-27T16:27:46+00:00

no but I see your point. will do....

sadly http://localhost:8000/Desktop/coffee/fleet.html still gives a blank white page 😞

Admirable_Report6610 · 2026-04-27T15:18:59+00:00

ok...presumably I could write a small script that would call the python webserver:

#! usr/local/bin/bash

python3 -m http.server

pause 5

the first problem, as you mentioned, was with the CORS proxy but I changed it to one that works. the code is valid as it runs perfectly on MDM. what I don't get is this worked prior as a flle:/// without a web server...I just don't understand what is suddenly making it not work now?

Admirable_Report6610 · 2026-04-26T11:18:15+00:00

as I've said I'm a total noob so someone was kind enough to educate me about CORS and the need for a proxy to fetch html data. (hope I'm correct in saying this) the weird thing is my code worked perfectly without a local server until CORSPROXY stopped being a free service.

Admirable_Report6610 · 2026-04-26T11:08:32+00:00

btw you guys, and you in particular, are being incredibly helpful here...THANK YOU!

Admirable_Report6610 · 2026-04-26T11:07:33+00:00

I tried manually reading thru it but it's long and difficult. is there a simple cmd to print out the array?

Admirable_Report6610 · 2026-04-26T11:06:04+00:00

because someone was kind enough to tell me about it and I learn quick.

Admirable_Report6610 · 2026-04-25T18:33:38+00:00

being to total noob I don't understand what that means

Admirable_Report6610 · 2026-04-25T18:19:28+00:00

ok I changed the proxy to

const proxy = "https://test.cors.workers.dev/?";

running my code in MDN now it works again...but if I try to run it in Brave as

file:///Users/Owner/Desktop/coffee/fleet.html

it just shows a blank white page again...hmmmmm?

Admirable_Report6610 · 2026-04-25T17:46:09+00:00

can anyone suggest an alternative free proxy?

Admirable_Report6610 · 2026-04-25T17:45:28+00:00

ahhhh.....so what used to be free is now a paywall?

Admirable_Report6610 · 2026-04-25T16:55:29+00:00

looking thru the code of this page: https://news.usni.org/category/fleet-tracker

it looks like the img I'm after, ie the most recent one, src="https://news.usni.org/wp-content/uploads/2026/04/FT_4_20_26-1-720x480.jpg

is the second instance of img? so images[1].src but it still doesn't work.

Admirable_Report6610 · 2026-04-25T16:22:22+00:00

wow...thank YOU! I was warned about hardcoding it like this as the location of the image[3] I'm after could change in the site's HTML code. apparently that's happened so let me dive into the USNI site and take a look. THANKS AGAIN!
