在上一篇文章《Python教程—模擬網(wǎng)頁點擊爬蟲定位系統(tǒng)》講解怎么通過模擬點擊方式爬取車輛定位數(shù)據(jù)，本次介紹怎么以模擬點擊方式進(jìn)入交管12123爬取車輛違章數(shù)據(jù)，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(wǎng)頁點擊爬蟲定位系統(tǒng)》同樣為企業(yè)中實際的爬蟲案例，如果之后想進(jìn)入車企行業(yè)可以做個了解。

準(zhǔn)備工具：spyder、selenium庫、google瀏覽器及對應(yīng)版本的chromedriver.exe

效果

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(yè)資產(chǎn)，本文程序以刪除網(wǎng)址、賬號密碼，該網(wǎng)址比較麻煩的一點是開始點擊登錄的時候網(wǎng)頁可能會有其他彈窗出現(xiàn)，使得原有路徑改變，程序會因為找不到對應(yīng)路徑而報錯，重新執(zhí)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(wǎng)頁，這種方式就可以繞過登錄的繁瑣步驟。
