如何使用django中的{{next}}变量重定向到具有GET参数的页面 [英] How to redirect to page which has GET parameters after login using the {{next}} variable in django

问题描述

我正在使用 allauth 在我的django网站上提供注册和登录。除了我遇到问题之外，其他一切似乎都正常工作，因为我在登录后将人员重定向到当前页面。

I am using allauth to provide registration and login in my django site. Everything else seems to be working fine other than that I am having problems to redirect the person to the current page after login.

我有一个页面，我有一些面试问题一个典型的网址就像

I have a page where I have some interview questions and a typical url for it would be like

/questions/?company=google

此页面包含公司google的问题列表，但要查看该人需要登录的答案。答案显示在下拉框中。然而，当用户点击登录时，请求将发送到登录页面，如下所示

This page contains a list of questions for the company google, but to view the answer the person needs to login. The answers are displayed in a dropdown box. However when the user clicks on login a request is sent to the login page as follows

/login/?next=/questions/

而实际在那里的get参数在我的实际页面中，因为我的url中的& 不发送。我如何解决这个问题。这个人看起来不太好，他被重定向到他/她试图登录的不同页面。

And the get parameter which was actually there in my actual page is not sent because of the & in my url. How can I solve this problem. It does not look nice that the person is redirected to a different page from where he/she tried to login.

我知道发送 / code>参数作为 GET 变量不是解决方案，但有一种方法可以发送重定向链接作为模板中的 POST 变量。

I know sending the next parameter as a GET variable is not the solution, but is there a way I can send the redirect link as a POST variable from the template.

我尝试过另一件事，在我看来，显示问题列表。我设置会话变量，其中包含当前链接的url。如果用户点击登录，在我的登录视图中，我检查这个特定的会话变量。如果设置了，那么我将重定向到该页面。

I tried another thing, in my view that displays the questions list. I set session variables which contains the url of the current link . If a user clicks on login, in my login view I check for this particular session variable. If it is set then I redirect to that page.

但是，在登录视图中没有收到会话变量，我不知道，但我认为当用户进入登录视图时会重置会话。

However the session variable is not received in the login view, I am not sure but I think the session is reset when the user goes to the login view.

任何建议都不胜感激。

推荐答案

参数在这种情况下。你想发送一个变量，如 / questions /？company = google ，但是你提到？， = （其中）字符是特殊字符。嵌入URL时具有特殊的意义。如果您使用URL编码编码变量，则变为％2Fquestions ％2F％3Fcompany％3Dgoogle 。如果将其分配给参数 next ，则URL将变为： / login /？next =％2Fquestions％2F％3Fcompany％3Dgoogle 。这应该在登录时重定向到正确的地方。

You should encode the URL-parameter in this case. You want to send a variable like /questions/?company=google, but as you mentioned the ?, = (amongst others) characters are special ones. It has a special meaning when embedded in the URL. If you encode the variable with URL encoding, it becomes %2Fquestions%2F%3Fcompany%3Dgoogle. If you assign that to the parameter next, the URL becomes: /login/?next=%2Fquestions%2F%3Fcompany%3Dgoogle. This should redirect to the correct place on login.
