django程序,需要写很多api,每个函数都需要几个装饰器,例如
@csrf_exempt
@require_POST
def foo(request):
pass
既然那么多个方法都需要写2个装饰器,或者多个,有啥办法把多个合并成一行呢?
上面的函数执行过程应该是
csrf_exempt(require_POST(foo))
修改成
def compose(*funs):
def deco(f):
for fun in reversed(funs):
f = fun(f)
return f
return deco
函数改写成
@compose(csrf_exempt, require_POST)
def foo(request):
pass
