So my goal is to send via api the image or pdf i have on odoo somewhere else.

the problem is i don't find the path of the odoo image I want to move, so i looked for it in :

invoice = self.env['account.move'].search([('id', '=', invoice_id)], limit=1)

attachments = invoice.attachment_ids

Where i found : attachments.local_url 

with this i could do : 

"http://localhost:8069/"+attachments.local_url

and it downloads it on my navigator.

so i'm like "ok i can download it here so i could just request it via code"

so I made this function : 

def url_to_document(self, url_attachments):

        import os

        import re

        import requests

        from urllib.parse import urlparse

        import mimetypes

        folder_path = './invoice/temp/'

        os.makedirs(folder_path, exist_ok=True)

        parsed_url = urlparse(url_attachments)

        raw_filename = os.path.basename(parsed_url.path) or 'downloaded_file'

        raw_filename = re.sub(r'[<>:"/\\|?*=]', '_', raw_filename)

        try:

            response = requests.get(url_attachments, headers={

                        "User-Agent": (

                            "Mozilla/5.0 (Windows NT 10.0; Win64; x64) "

                            "AppleWebKit/537.36 (KHTML, like Gecko) "

                            "Chrome/114.0.0.0 Safari/537.36"

                        ),

                        "Accept": "application/pdf,application/octet-stream;q=0.9,*/*;q=0.8",

                        "Accept-Encoding": "identity",

                    })

            response.raise_for_status()

            content_type = response.headers.get("Content-Type", "").lower()

            extension = mimetypes.guess_extension(content_type.split(';')[0]) or '.bin'

            if content_type == 'application/pdf':

                extension = '.pdf'

            elif content_type == 'image/png':

                extension = '.png'

            elif content_type == 'image/jpeg':

                extension = '.jpg'

            filename = os.path.splitext(raw_filename)[0] + extension

            full_file_path = os.path.join(folder_path, filename)

            with open(full_file_path, 'wb') as f:

                f.write(response.content)

            print(f"✅ Saved as: {full_file_path}")

            return full_file_path

        except requests.RequestException as e:

            print(f"❌ Error downloading file: {e}")

            return None

The problem : 

1. The function does request something but for some reason it gets a png enven thought on the web it's a pdf
2. the png img is a default camera logo

solutions : ??

1. Is there another solution you guys have to find the document
2. am i missing something evident in my code or the way this "http://localhost:8069/"+attachments.local_url works ?

Thank you for the read,

have a nice day
