Question

我有一个带蓝图结构的模块化应用程序。我注册了蓝图，他们工作正常。我遇到了带参数的url_for问题：

werkzeug.routing.BuildError：无法使用值['token']

为端点'confirm_email'构建网址

这是我在 home.py

中的端点

@home.route('/register',methods=['GET','POST'])
def register():

    form = RegistrationForm(request.form)
    print(form, file=sys.stderr)
    print(form.email, file=sys.stderr)
    if request.method == 'POST' and form.validate():
        u = User(
            email = form.email.data,
            password = form.password.data
        )
        email_ddbb = User.query.filter_by(email=form.email.data).first()
        # we register the user
        if email_ddbb is None:
            # Now we'll send the email confirmation link
            subject = "Confirm your email"
            token = ts.dumps(u.email, salt='email-confirm-key')
            print(url_for('user.activate',token=token,_external=True))
            confirm_url = url_for('user.activate',token=token,_external=True)
            html = render_template('mail/activate.html', confirm_url=confirm_url)
            # we send the email from utils.py
            send_email(u.email, subject, html)
            db.session.add(u)
            db.session.commit()
            flash('Thanks for registering, please check your inbox')
            return redirect(url_for('home.index'))
        else:
            flash('Email already in use')
            return redirect(url_for('home.index'))
        #TODO MUST BE UNIQUE
    else:
        flash('Please enter a valid email address')
        return redirect(url_for('home.index'))

这是 user.py

中的另一个端点

@user.route('/confirm/<token>')
def activate(token):
    try:
        email = ts.loads(token, salt="email-confirm-key", max_age=86400)
    except:
        abort(404)
    user = User.query.filter_by(email=email).first_or_404()
    user.verified = True
    db.session.add(user)
    db.session.commit()
    return redirect(url_for('home.index'))

Okey，问题不在那里，而是在邮件中：

def send_email(to, subject, template, **kwargs):
    msg = Message(app.config['MAIL_SUBJECT_PREFIX'] + subject,
                      sender=app.config['MAIL_SENDER'], recipients=[to])
    msg.body = ''
    token = ts.dumps(to, salt='email-confirm-key')

    confirm_url = url_for(
        'confirm_email', <-- should be user.activate 
        token=token,
        _external=True)

    msg.html = render_template(
            'activate.html',
            confirm_url=confirm_url)
    mail.send(msg)
