在上一篇文章《Python教程—模擬網頁點擊爬蟲定位系統》講解怎么通過模擬點擊方式爬取車輛定位數據，本次介紹怎么以模擬點擊方式進入交管12123爬取車輛違章數據，本文直接講解過程，使用的命令解釋見上一篇文章。本文同《Python教程—模擬網頁點擊爬蟲定位系統》同樣為企業中實際的爬蟲案例，如果之后想進入車企行業可以做個了解。
注：分享此案例目的是為了幫助同行解放雙手，更好管理企業資產，本文程序以刪除網址、賬號密碼，該網址比較麻煩的一點是開始點擊登錄的時候網頁可能會有其他彈窗出現，使得原有路徑改變，程序會因為找不到對應路徑而報錯，重新執行程序即可。除了模擬點擊登錄，還可以直接通過Cookie直接登錄網頁，這種方式就可以繞過登錄的繁瑣步驟。
