我已经尝试下载纳斯达克ITCH文件，但遇到了[WinError 10060]:
from urllib.request import urlretrieve
urlretrieve('ftp://emi.nasdaq.com/ITCH/Nasdaq ITCH/', '10302019.NASDAQ_ITCH50.gz')

我试着在谷歌上搜索，有人说这是代理问题，但有人能帮助启发我的正确问题吗?非常感谢。
from urllib。请求导入urlretrieve
urlretrieve (' https://emi.nasdaq.com/ITCH/Nasdaq%20ITCH/', ' 10302019. nasdaq_itch50.gz ')
上面的工作，只是通过将ftp更改为https和'Nasdaq ITCH'更改为'Nasdaq%20ITCH/'。
