在Django中重定向操作URL片段

Question

我一直在使用Django的auth模块,但最近不得不关闭它.auth模块通过重定向到登录页面并将您从中注销的页面设置为?next=/currentPage参数来处理会话过期.

因此,如果我的会话到期,#dashboard我将被重定向到:

mydomain/account/login?next=/#dashboard

离开Django auth模块后,我注意到这已经改为:

mydomain/account/login/#dashboard

这看起来与我理解它在阅读URL Fragment和302重定向后应该起作用的方式一致,但是,我想操纵这个片段但是在我的HttpResponse对象中没有看到它.

django.contrib.auth使用以下函数来处理此请求,但我看不到它们移动片段的位置.实际上我只是想完全删除片段,但如果我不能,我会满足于将它放回?next=参数中.

def user_passes_test(test_func, login_url=None, redirect_field_name=REDIRECT_FIELD_NAME):
    """
    Decorator for views that checks that the user passes the given test,
    redirecting to the log-in page if necessary. The test should be a callable
    that takes the user object and returns True if the user passes.
    """

    def decorator(view_func):
        @wraps(view_func, assigned=available_attrs(view_func))
        def _wrapped_view(request, *args, **kwargs):
            if test_func(request.user):
                return view_func(request, *args, **kwargs)
            path = request.build_absolute_uri()
            # urlparse chokes on lazy objects in Python 3, force to str
            resolved_login_url = force_str(
                resolve_url(login_url or settings.LOGIN_URL))
            # If the login url is the same scheme and net location then just
            # use the path as the "next" url.
            login_scheme, login_netloc = urlparse(resolved_login_url)[:2]
            current_scheme, current_netloc = urlparse(path)[:2]
            if ((not login_scheme or login_scheme == current_scheme) and
                (not login_netloc or login_netloc == current_netloc)):
                path = request.get_full_path()
            from django.contrib.auth.views import redirect_to_login
            return redirect_to_login(
                path, resolved_login_url, redirect_field_name)
        return _wrapped_view
    return decorator


def login_required(function=None, redirect_field_name=REDIRECT_FIELD_NAME, login_url=None):
    """
    Decorator for views that checks that the user is logged in, redirecting
    to the log-in page if necessary.

    actual_decorator = user_passes_test(
        lambda u: u.is_authenticated(),

        redirect_field_name=redirect_field_name
    )
    if function:
        return actual_decorator(function)
    return actual_decorator

他们没有删除它.片段永远不会发送到后端:这就是浏览器的工作方式.

请注意,您的原始网址根本不会被解释next="/#dashboard",而是next="/"使用"信息中心"的后续片段.也就是说,片段与查询字符串是分开的,而不是它的一部分.

您需要做的是对哈希进行编码,使其成为查询字符串本身的一部分.

mydomain/account/login?next=/%23dashboard
