1-关于用户登陆返回原访问登陆页面

一句话概括：在GET请求的时候获取一个原网页的链接， 之后再POST表单提交过之后，把这个原网页链接，拿过来使用

 1 def register(request):
 2     if request.method == ‘GET‘:
 3         ret = render(request, ‘register.html‘)
 4         ret.set_cookie(‘register_form‘, request.META.get(‘HTTP_REFERER‘, ‘/‘))
 5         return ret
 6     else:
 7         name = request.POST.get(‘name‘, ‘‘)
 8         password = request.POST.get(‘password‘, ‘‘)
 9         register_form = request.COOKIES.get(‘register_form‘, ‘‘)
10         if register_form:
11             ret = HttpResponse(f"""
12                 返回原网页
13                 <a href=‘{register_form}‘>点击返回原网页</a>
14             """)
15             ret.set_cookie(‘name‘, name)
16             print(register_form, ‘<<<<<<<<<<<<<register, 1‘)
17             return ret
18         else:
19             print(register_form, ‘<<<<<<<<<<<<<register, 0‘)
20             return redirect(reverse(‘index‘))
