我一直在尝试为网站的重置密码编码。但是，我继续遇到405错误。 Google说这很可能是客户端错误，但我认为我的html很好。我不确定还有什么可能导致该错误。

我已经尝试过在没有内容的情况下测试url，但这也没有起作用。

routes.py

def send_reset_email(user):
    token = user.get_reset_token()
    msg = Message('Password Reset Request',sender='noreply@clubsapp.com',recipients=[user.email])
    msg.body = f'''To reset your password,visit the following link:
{url_for('reset_token',token=token,_external=True)}

If you did not make this request then simply ignore this email and no change will be made.
'''
    mail.send(msg)

@users.route('/reset_request',methods=['GET,POST'])
def reset_request():
    if current_user.is_authenticated:
        return redirect(url_for('main.home'))
    form = RequestResetform()
    if form.validate_on_submit():
        user = User.query.filter_by(email=form.email.data).first()
        send_reset_email(user)
        flash('An email has been sent with instructions to reset your password','info')

        user.password = hashed_password
