在html的form中使用给url定义的name值，可以在修改url时不用在修改form的src。
urls.py
from django.conf.urls import url
from mytest import viewsurlpatterns = [# url(r'^admin/', admin.site.urls),url(r'^index/', views.index, name='mysite'),
views.Index.as_view()),
]
views.py
from django.http import HttpResponse
from django.shortcuts import renderdef index(req):if req.method == 'POST':print('method is :' + req.method)elif req.method == 'GET':print('method is :' + req.method)return render(req, 'index.html')
index.html
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>index</title>
</head>
<body><form action="{% url 'mysite' %}" method="post"><input type="text" name="A" /><input type="submit" name="b" value="提交" /></form>
</body>
</html>由上述代码可以看到url的name使用方法。
