Urls:
from django.urls import path
from . import views
urlpatterns = [
path("test",views.test),
#一旦调用test1，那么kwargs将会以关键字的a=100，b=200这样的形式传给test1
path("test1", views.test1,kwargs={"a":100,"b":200}),
#test2(request,year,month
path("test2/ < year > / < month > ", views.test2),
path("test3", views.test3),
path("test5", views.test5),
path("test6", views.test6),
path("test7", views.test7),
path("test8", views.test8),
]

后端视图。使用request.FILES.get(“”)接收数据
def test8(request):
for key in ["file22","file33"]:
file=request.FILES.get(key)
with open(file.name,"wb") as f:
f.write(file.read())
return HttpResponse("显示form")
返回：
上传两个文件到url同文件夹下面
