在urls.py里可以直接向函数传递默认值，看代码：

urls.py

from django.conf.urls import url
from mytest import views

urlpatterns = [
    url(r'^index/', views.index, {'my': '呵呵'}),
]

views.py

from django.shortcuts import render

def index(req, my):
    return render(req, 'index.html', {'data': my})

html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>index</title>
</head>
<body>
    <h1>{{ data }}</h1>
</body>
</html>

看效果：
