如何将类字段作为参数传递给类方法上的装饰器？我想做的是:

class Client(object):
    def __init__(self, url):
        self.url = url

    @check_authorization("some_attr", self.url)
    def get(self):
        do_work()

它抱怨自我不存在将self.url传递给装饰者.有没有解决的办法？

我试图弄清楚如何运行Python的line_profiler来逐行执行这个问题的答案中给出的格式.

我安装了模块并调用它的LineProfiler对象如下所示,但我得到的输出只是一次,而不是逐行汇总.

有任何想法吗？此外,我如何获得numbers = [random.randint(1,100) for i in range(1000)]任何功能之外的线路的时间？

from line_profiler import LineProfiler
import random

def do_stuff(numbers):

    s = sum(numbers)
    l = [numbers[i]/43 for i in range(len(numbers))]
    m = ['hello'+str(numbers[i]) for i in range(len(numbers))]

numbers = [random.randint(1,100) for i in range(1000)]
profile = LineProfiler(do_stuff(numbers))
profile.print_stats()
[] Timer unit: 3.20721e-07 s

我想使用 line profiler 来分析我的 django 项目以显示代码性能的分析。

但这对我不起作用。我收到有关开发服务器的错误，如下所示：
