步驟一：點(diǎn)擊數(shù)據(jù)分析

點(diǎn)擊滑動按鈕，將發(fā)送一個請求到/zfcaptchaLogin

通過base64解密mt和extend得出解密的數(shù)值

mt為用戶的點(diǎn)擊行為，x為X軸上的值，y為Y軸上的值，t為時間戳。通過大量點(diǎn)擊分析，發(fā)現(xiàn)x值最小值為950，得出950為X軸的起點(diǎn)，y值隨機(jī)無固定值。

extend為請求頭部內(nèi)容

步驟二：滑動驗證碼圖像分析，計算滑動距離x值

將圖像灰度化，通過getpixel可以獲取圖像某一點(diǎn)的顏色值，顏色值越高代表圖像越淺，所以尋找縱向連續(xù)50個像素點(diǎn)均是getpixel(x+1,y)getpixel(x,y)（X軸=x比X軸=x+1顏色淺）

并掃描圖像，當(dāng)x=130、掃描高度=50時，的顏色比x+1時深。
