关于python：Django：HttpResponseRedirect不起作用

Django: HttpResponseRedirect not working

我是Python / Django和整体编程的新手。我需要有关HttpResponseRedirect的帮助，因为它无法从我的登录视图工作。它确实可以从我的主Views文件工作，但不能按我想要的方式工作。

我没有重定向到所需的页面('/')，而是仅在同一页面上看到此内容：

Content-Type: text/html; charset=utf-8 Location: /

用户实际上已登录，但停留在同一页面上。因此，如果我手动转到所需的页面，将会看到我已登录。

这是相关的代码段。我到处都有自己的看法。我希望通过这种方式进行练习和更好地理解。

<form action="./" method="post">

<input type="submit" value="login" />
<input type="hidden" name="next" value="/" />
{% csrf_token %}
</form>

</center>

我按照Django的书籍教程进行操作，根据它，一切都应该正常工作。如您所见，我还尝试过在表单中??使用"下一个"隐藏字段，但该字段也不起作用。任何帮助，将不胜感激。我想知道我在这里想念的是什么。谢谢！

相关讨论

在HTML中看到" Content-Type：文本/ html； charset = utf-8位置：/"的原因是，您将HttpResponse对象作为上下文数据的一部分返回，以呈现在响应中，而不是实际反应。您登出后看起来也有些怪异。但是要使用您当前拥有的东西：

更改您的views.py

if not request.user.is_authenticated():
# LoginView.login_view will return a HttpResponse object
return LoginView.login_view(request)
else:
...

然后在LoginView.login中更改视图以始终返回所需的Response对象(重定向或所需呈现的页面)
