Python URL中的可选参数

我有一个端点：

@register_endpoint.route('/<string:token>/verify', methods=['GET'])
def display_register_form(token):
    error = None
    decrypted_token = SecureMessage().decrypt(token)
    user_data = json.loads(decrypted_token)
    form = RegisterAccountForm()
    return render_template("auth/account_validation.html", form=form, error=error, user_data=user_data)


@register_endpoint.route('/<string:token>/verify', methods=['POST'])
def register_account():
    form = SignupForm(request.form)
    if form.validate_on_submit():
        email = form.email.data
        first_name = form.first_name.data
        last_name = form.last_name.data
        password = form.password.data
        json_user = json.dumps({"first_name": first_name, "last_name": last_name, "email": email, "password": password})
        response = requests.post("http://0.0.0.0:5000/api/v1/accounts", json=json_user)
        if response.status_code == 200:
            return redirect(url_for('account.signin'))

我怎样才能解决这个问题？我可以将令牌设置为可选的吗？解决我的问题的最佳架构是什么？

可能的重复：@mel尝试将（'register.register\u account'）的

url\u更改为（'register.register\u account'，token=form.csrf\u token）

。在您的路由中，令牌是必需的参数。顺便说一句，您忘了将arg令牌添加到

register\u帐户

<form action="{{ url_for('register.register_account') }}" method="post">
        <input name="first_name" class="user" type="text" required="" placeholder="{{ user_data["first_name"] }}" disabled/><br>
        <input name="first_name" class="user" type="text" required="" placeholder="{{ user_data["last_name"] }}" disabled/><br>
        <input name="email" class="user" type="text" required="" placeholder="{{ user_data["email"] }}" disabled/><br>
        <input  placeholder="Password" name="password" class="pass" type="password" required=""><br>
        <input  placeholder="Password verification" name="password_verification" class="pass" type="password" required=""><br>
        {{ form.csrf_token }}
        <input type="submit" value="">
    </form>

Could not build url for endpoint 'register.register_account'. Did you forget to specify values ['token']?
