Django重定向正确的方式?

我对此有类似的问题 -
Conditional login redirect in Django

但我无法理解如何从答案中获得结果。

我对django比较新。我从某个地方重用了这个代码,将用户重定向到登录页面。但登录后我总是到达用户的开始/主页。我希望他们能够看到他们真正要求的页面,而不是用户主页。你能告诉我我可以在哪里和哪里做出改变,它应该是我使用“重定向”功能的地方。我可能应该保存一些会话变量并做到但不完全得到起点。有什么想法吗?

以下是代码 -

def view_or_basicauth(view, request, test_func, realm = "", *args, **kwargs):
    if test_func(request.user): # Already logged in, just return the view.
        return view(request, *args, **kwargs)

    # They are not logged in. See if they provided login credentials
    if 'HTTP_AUTHORIZATION' in request.META:
        auth = request.META['HTTP_AUTHORIZATION'].split()
        if len(auth) == 2:
            # NOTE: We are only support basic authentication for now.
            if auth[0].lower() == "basic":
                uname, passwd = base64.b64decode(auth[1]).split(':')
                user = authenticate(username=uname, password=passwd)
                if user is not None:
                    if user.is_active:
                        login(request, user)
                        request.user = user
                        return view(request, *args, **kwargs)

    # Either they did not provide an authorization header or something in the authorization attempt  failed. Send a 401 back to them to ask them to authenticate.
    key = request.path.split('/')
    if len(key) > 1:
        base_url = request.get_host()
        return redirect( 'https://' + base_url + '/login/')

    s = '401 Unauthorized'
    response = HttpResponse(s)
    response.status_code = 401
    response['Content-Length'] = '%d' % len(s)
    response['WWW-Authenticate'] = 'Basic realm="%s"' % realm
    return response

这很直接:

将GET参数添加到重定向行,以便您的登录视图知道您的用户来自哪里。它可以是任何东西,但我正在使用"?redirect=myurl"

在您的登录视图中:成功登录后检查GET中是否存在该密钥(redirect)。如果存在,则重定向到该值。

首先修改您的重定向行:

# add a GET parameter to your redirect line that is the current page
return redirect( 'https://' + base_url + '/login/?redirect=%s' % request.path )

然后在您的登录视图中,只需在GET中检查您的变量并重定向到该值(如果存在)。

# modify the login view to redirect to the specified url
def login(request):
    # login magic here.

    if login_successful:
        redirect = request.GET.get('redirect') # get url

        if redirect:
            # redirect if a url was specified
            return http.HttpResponseRedirect(redirect) 

        # otherwise redirect to some default
        return http.HttpResponseRedirect('/account/home/')
    # ... etc

在重定向中将URL作为GET参数传递,并让重定向目标在输入凭据后重定向它们。
