I got ban from TWSE after running the unit test twice

[Ian Lin]

I got ban from TWSE after running the unit test twice.
I am very sure that I am not running other crawler at the same time.
The unit test is very dangerous. Maybe we should add some delay between requests, or mock almost all the requests.

What kind of ban do you get? The whole RealtimeTest get failed? I'm currently fixing this issue for the unittest.

While calling TWSEFetcher.fetch, I got [Errno 101] Network is unreachable, and my browser cannot open http://www.tse.com.tw/. It's a typical ban when you request TWSE too frequently.

I can reproduce this when doing the unittest twice

...
urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='www.twse.com.tw', port=80): Max retries exceeded with url: /exchangeReport/STOCK_DAY?date=20180101&stockNo=2330 (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f5432992898>: Failed to establish a new connection: [Errno 101] Network is unreachable',))

我也有類似的問題
我成功執行一次，但第二次就不work了
HTTPConnectionPool(host='www.twse.com.tw', port=80): Max retries exceeded with url: /exchangeReport/STOCK_DAY?date=20180401&stockNo=2303 (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x10f8c40f0>: Failed to establish a new connection: [Errno 61] Connection refused',))

I've try using request.Session, but it still don't work :(

someone said the limit is 5s/3 query
