瓶框架中的多种途径和功能

Question

I'm trying to modify already existing code, simply add form to add photos.

python:

@route('/photos/add')
@jinja_view('add.html')
@post('/photos/add')
def upload_func():
    upload = request.files.get('pic')
    name, ext = os.path.splitext(upload.filename)
    if ext not in ('.png', '.jpg', '.jpeg'):
        return "ext is not allowed"
    save_path = "/src/photo_gallery/photos"
    upload.save(save_path)
    return "photo is saved"

HTML:

<form action="/photos/add" method="post">
    <div align="center">
        <label>Picture</label>
        <input type="file" name="pic" required>
    </div>
    <div>
        <label>Info</label>
        <input type="text" name="text">
    </div>
    <div>
        <input type="submit" value="add">
    </div>
</form>

Answer 1

You have linked the url path /photos/add to the callback function upload_func . It looks like you want to support two request types (GET and POST), then function decorators should look like this:

@route('/photos/add', method=['GET', 'POST'])
@jinja_view('add.html')
def upload_func():
    # ...

Take a look at:

Please also note that the code should not be written like this - too complex
