三、檢視fake-useragent版本

1、使用pip list指令檢視fake-useragent版本

(scrapytest) F:\python-virtualenv\scrapytest\Scripts>pip list

attrs (17.3.0)

Automat (0.6.0)

certifi (2017.11.5)

cffi (1.11.2)

chardet (3.0.4)

constantly (15.1.0)

cryptography (2.1.3)

cssselect (1.0.1)

enum34 (1.1.6)

fake-useragent (0.1.8)

hyperlink (17.3.1)

idna (2.6)

通路https://fake-useragent.herokuapp.com/browsers/0.1.8檢視useragent庫

四、user-agent庫

<a href="https://fake-useragent.herokuapp.com/browsers/0.1.4">https://fake-useragent.herokuapp.com/browsers/0.1.4</a>

json格式顯示的，可以把内容複制到以下網址進行json視圖顯示
