我有：
urlpatterns = [
url(r'^tools(?:/\?tool_one=(?P<tool_one>\w+))?/?$', views.ToolsViews.as_view(), name='tools'),
]
像这样的url打印：
tools / tool_one =袋子
我想在网址中添加一个问号：
tools /？tool_one =袋子
我试图写：

但问号不存在，URL的打印：
tools /％3Ftool_one =袋子
有人可以给我一些提示吗？有什么问题吗？
答案 0 :(得分：2)
您在这里描述的是 querystring 。查询字符串不是由Django URL处理的。但是，您可以通过基于函数的视图中的request.GET或基于类的视图中的self.request.GET访问查询字符串的数据。
request.GET是QueryDict。它就像字典一样（除了它是不可变的，而且键可以映射到多个值）。
因此，您可以使用tool_one获得self.request.GET['tool_one']的值（与查询字典的方式相同）。
由于这不是Django URL的一部分，因此urls.py文件看起来像：
# app/urls.py
urlpatterns = [
url(r'^tools/$', views.ToolsViews.as_view(), name='tools'),
]然后在视图中，例如，可以使用它进行过滤，例如：
class ToolsViews(ListView):
model=Tool
def get_queryset(self):
if 'tool_one' in self.request.GET:
return Tool.objects.filter(one=self.request.GET['tool_one'])
return Tool.objects.all()最后，您可以使用以下模板在模板中构建此类URL：
<a href="{% url 'tools' %}?tool_one=foo">Link</a>或通过使用<form>方法编写"get"：
<form action="{% url 'tools' %}" method="get">
Tool one: <input type="text" name="tool_one"><br>
<input type="submit" value="Submit">
</form>带有method="get"的这种形式会将文本框中的值转换为查询字符串。
