Home Request
1, no codes
2, a verification code to
The second request
We can see that, when the captcha a first transmission request response when show_captcha is False, this code is not required; if you need Ture login codes,
Further captcha will immediately send a second request, the response can be obtained img_base64, i.e., the encrypted image.
3、
Should be that the data we need
We need to see the data example, the signature is encrypted, so we need to look at is what the hell signature
Js come together can crawl through an encrypted part
