The error there is resulting from a BadRequestKeyError
because of access to a key that doesn’t exist in request.form
.
ipdb> request.form['u_img']
*** BadRequestKeyError: 400 Bad Request: The browser (or proxy) sent a request that this server could not understand.
Uploaded files are keyed under request.files
and not request.form
dictionary. Also, you need to lose the loop because the value keyed under u_img
is an instance of FileStorage
and not iterable.
@app.route("https://stackoverflow.com/", methods=['GET', 'POST'])
def index():
target = os.path.join(app_root, 'static/img/')
if not os.path.isdir(target):
os.makedirs(target)
if request.method == 'POST':
...
file = request.files['u_img']
file_name = file.filename or ''
destination = "https://stackoverflow.com/".join([target, file_name])
file.save(destination)
