Import image with Odoo API in Python 3.4

Question

I'm working on a script to import a list of product in my Odoo database. The script is working really fine with the Odoo API, except for importing the image. What I have done so far, is to import an image from an URL in python, and then, encoding it in base64:

    response = requests.get(image_url)
    img_obj = Image.open(BytesIO(response.content))
    buffer = BytesIO()
    img_obj.save(buffer, format="JPEG")
    img = base64.encodestring(buffer.getvalue()).strip()
    try:
        base64.b64decode(img)
    except TypeError:
        padding = len(img) % 4
        if padding == 1:
            img = "Invalid base64 string: {}".format(img)
        elif padding == 2:
            img += b'=='
        elif padding == 3:
            img += b'='

This code is working great. But, when I run the python code to import it with Odoo API, here is what I have:

Error: Incorrect padding

I have tried to correct the base64 padding, (as you can see in my previous code), but that's not working. Did anyone know how can I fixe this problem? May it come from my script, which is in Python 3.4 wheras Odoo is in Python 2.7 ?

Thanks,

Answer 1

Ok, I finaly find out the problem. As I was wondering, the problem come from the difference between Python 3.4 et Python 2.7. I just run my code in python 2.7, changing just some library importation, and now, it's work :-)

Hope this could help someone!
