httt --interval 0.2 --port 9000

• 然后，打开一个已安装requests的Python shell。并观察requests.get中的timeout kwarg并不意味着请求超时

>>> import requests
>>> import time
>>>
>>> def time_it():
...     start = time.perf_counter_ns()
...     response = requests.get("https://127.0.0.1:9000", timeout=1)
...
...     # Notice how even though `timeout=1` suggests the request 
...     # will timeout if it takes longer than 1 second, but it actually takes 
...     # around 3 seconds before completing and it is allowed to run uninterrupted.
...
...     end = time.perf_counter_ns()
...     print("request took: {(end - start)/1e9:.3f} seconds")
...
>>> time_it()
request took: 3.823 seconds

• 如果相反，你用3秒超时curl服务器，则它会提前关闭连接，正如预期的那样

$ curl -v -m 3 https://127.0.0.1:9000
