Getting 'KeyError: destination' when making redirection to oAuth provider using redirect_to_auth_server()

Question

我想要一种使用 flask-oidc.
激活和停用 OIDC 检查的方法使用 @require_login 装饰器是一个问题，因为它无法停用。例如：

g_use_oidc = True # <= A global boolean to activate or deactivate OIDC at application level

@app.route('/') # <= Flask routing
@require_login # <= Flask-OIDC making redirection to oAuth provider
def home():
    return render_template('index.html')

当我被重定向到我的 oAUth 提供商时，这与 OIDC 配合得很好。但现在我希望将 g_use_oidc 设置为 False 并将 @require_login 设置为停止重定向呼叫。

为了实现这一点，我创建了一个装饰器来检查 g_use_oidc 状态，如下所示：

def check_oidc_test(func):

    @wraps()
    def inner():
        if not use_oidc or oidc.user_loggedin == True:
            func()
        elif use_oidc and oidc.user_loggedin == False:
            return oidc.redirect_to_auth_server(None, request.values) # <= Redirection to OIDC provider as shown in the doc
    return inner

我应该可以像这样使用装饰器：

@app.route('/')
@check_oidc # <= my new decorator
def home():
    return render_template('index.html')

不幸的是，我从 OIDC 得到了这个堆栈跟踪：

解决了。

我查看了 @require_login 的代码，它看起来像这样：

if g.oidc_id_token is None:
    return self.redirect_to_auth_server(request.url)

(require_login_code)

所以我不远...

我更新了装饰器以匹配他们的装饰器

def check_oidc(view_func):
    @wraps(view_func)
    def decorated(*args, **kwargs):
        if g_use_oidc is True and oidc.user_loggedin == False:
            return oidc.redirect_to_auth_server(request.url)
        return view_func(*args, **kwargs)
    return decorated

它使用的是从 1.0.0 开始弃用的 oidc.redirect_to_auth_server。但它是 @require_login 内部使用的函数，因此不建议弃用它。
