Jak załadować i zapisać plik przy użyciu butelka ramowa

Question

HTML:

<form action="/upload" method="post" enctype="multipart/form-data"> 
    Category:  <input type="text" name="category" /> 
    Select a file: <input type="file" name="upload" /> 
    <input type="submit" value="Start upload" /> 
</form> 

Widok:

@route('/upload', method='POST') 
def do_login(): 
    category = request.forms.get('category') 
    upload  = request.files.get('upload') 
    name, ext = os.path.splitext(upload.filename) 
    if ext not in ('png','jpg','jpeg'): 
     return 'File extension not allowed.' 

    save_path = get_save_path_for_category(category) 
    upload.save(save_path) # appends upload.filename automatically 
    return 'OK' 

Próbuję zrobić ten kod, ale to nie działa. Co robię źle?

Od butelki 0,12 potrzeb klasy FileUpload zrealizowano z upload.save() funkcjonalności.

Oto przykład dla Bottle-0,12:

import os 
from bottle import route, request, static_file, run 

@route('/') 
def root(): 
    return static_file('test.html', root='.') 

@route('/upload', method='POST') 
def do_upload(): 
    category = request.forms.get('category') 
    upload = request.files.get('upload') 
    name, ext = os.path.splitext(upload.filename) 
    if ext not in ('.png', '.jpg', '.jpeg'): 
     return "File extension not allowed." 

    save_path = "/tmp/{category}".format(category=category) 
    if not os.path.exists(save_path): 
     os.makedirs(save_path) 

    file_path = "{path}/{file}".format(path=save_path, file=upload.filename) 
    upload.save(file_path) 
    return "File successfully saved to '{0}'.".format(save_path) 

if __name__ == '__main__': 
    run(host='localhost', port=8080) 

Uwaga: os.path.splitext() funkcja daje rozszerzenie w”<ext>. "Format, a nie" <ext> ".

• przypadku korzystania z wersji poprzedniej do butelki 0,12, zmiany:

  ... 
  upload.save(file_path) 
  ... 
  

do: serwer

... 
    with open(file_path, 'w') as open_file: 
     open_file.write(upload.file.read()) 
    ... 

• Run;
• Wpisz "localhost: 8080" w przeglądarce.
