foreword
When a crawler engineer encounters reverse engineering, if you use selenuim or pyppeteer, have you considered checking the characteristics of the browser so that you can pass the defense.
In short, I personally think it’s not bad, these attribute value checks are quite comprehensive, so I collected them, don’t say Just do IT, let’s get bored~~~
