Question

我在python 2.7上使用tornado 3.2，异步装饰器抛出错误。错误是：

[~code]$ python server.py 
Traceback (most recent call last):
File  "server.py", line 15, in <module>
class UploadHandler(tornado.web.RequestHandler):
File "server.py", line 16, in UploadHandler
@asynchronous
NameError: name 'asynchronous' is not defined

这是我使用装饰器的代码：

class UploadHandler(tornado.web.RequestHandler):
    @asynchronous
    def post(self):
      print "In post"
      self.redirect("/upload.html")

任何建议都会很棒

Answer 1

您需要使用完全限定名称：

class UploadHandler(tornado.web.RequestHandler):
    @tornado.web.asynchronous
    def post(self):
        print("In post")
        self.redirect("/upload.html")

或者，您可以导入所有tornado.web以使用单个名称：

from tornado.web import *
