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。

準備工具：spyder、selenium庫、google瀏覽器及對應版本的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。

from selenium import webdriverimport timeimport csvimport datetimefrom selenium.webdriver.common.by import Byfrom selenium.webdriver.support import expected_conditions as ECfrom selenium.webdriver.support.wait import WebDriverWaitimport mathimport xlrd

讀取需要查詢的車牌號

data = xlrd.open_workbook(’cheliang.xlsx’)

創建瀏覽，打開網頁

opt = webdriver.ChromeOptions() #創建瀏覽#opt.set_headless() #無窗口模式driver = webdriver.Chrome(options=opt) #創建瀏覽器對象driver.maximize_window() #最大化窗口​print('正在打開網頁')driver.get(’’) #打開網頁

依次點擊單位登錄、輸入賬號、密碼、點擊驗證碼填寫區域觸發圖片、勾選、輸入驗證碼、點擊登錄

time.sleep(3) #加載等待print('點擊單位登錄')time.sleep(3) #加載等待driver.find_element_by_xpath('/html/body/div[1]/div[2]/div/div[2]/div[2]/button').click()#點擊單位登錄​time.sleep(3) #加載等待print('正在填寫賬號')elem = driver.find_element_by_xpath('/html/body/div[4]/div/div[1]/div/div[2]/form[1]/div[1]/div/input')# 清空原有內容elem.clear()# 填入賬號elem.send_keys('')​time.sleep(1) #加載等待print('正在填寫密碼')elem = driver.find_element_by_xpath('/html/body/div[4]/div/div[1]/div/div[2]/form[1]/div[2]/div/input')# 清空原有內容elem.clear()# 填入密碼elem.send_keys('')​time.sleep(1) #加載等待print('正在查看驗證碼')driver.find_element_by_xpath('/html/body/div[4]/div/div[1]/div/div[2]/form[1]/div[3]/div/input').click()#查看驗證碼print('請輸入驗證碼')yanzhengma=input()​time.sleep(1) #加載等待driver.find_element_by_xpath('/html/body/div[4]/div/div[1]/div/div[2]/form[1]/div[4]/div/label/input').click()#勾選​time.sleep(1) #加載等待# 填入驗證碼elem = driver.find_element_by_xpath('/html/body/div[4]/div/div[1]/div/div[2]/form[1]/div[3]/div/input')elem.clear()elem.send_keys(str(yanzhengma))​time.sleep(1) #加載等待print('正在登陸')driver.find_element_by_xpath('/html/body/div[4]/div/div[1]/div/div[2]/form[1]/div[5]/button').click()#點擊

點擊違法查詢，設置查詢時間

driver.find_element_by_xpath('/html/body/div[4]/div/div[1]/div/div[2]/form[1]/div[5]/button').click()#點擊 time.sleep(3) #加載等待driver.find_element_by_xpath('/html/body/div[4]/div/div[1]/ul/li[5]/a').click()#點擊違法查詢 time.sleep(1) #加載等待driver.find_element_by_xpath('/html/body/div[3]/div/div[2]/div[1]/div[2]/form/div[1]/div/div[1]/span/i').click()#點擊選擇日期 for i in range(3): time.sleep(0.5) #加載等待 driver.find_element_by_xpath('/html/body/div[6]/div[4]/table/thead/tr/th[1]/i').click()#點擊 time.sleep(0.5) #加載等待driver.find_element_by_xpath('/html/body/div[6]/div[4]/table/tbody/tr/td/span[1]').click()#點擊 time.sleep(0.5) #加載等待driver.find_element_by_xpath('/html/body/div[6]/div[3]/table/tbody/tr[2]/td[1]').click()#點擊

循環依次查詢每個車牌違章信息，每次都需要清空上次輸入，填寫本次查詢車牌，識別有多少條數據，共多少頁，每頁最多展示10條，最后一頁有多少條數據

for ii in range(0,nrows): rowValues= table.row_values(ii) #某一行數據 print(’正在讀取第’+str(ii+1)+’輛車’)# 填寫車牌 time.sleep(0.5) #加載等待 elem = driver.find_element_by_xpath('/html/body/div[3]/div/div[2]/div[1]/div[2]/form/div[3]/div/input') elem.clear() elem.send_keys(rowValues)#輸入車牌 time.sleep(0.1) #加載等待 driver.find_element_by_xpath('/html/body/div[3]/div/div[2]/div[1]/div[2]/form/div[4]/button').click()#點擊查詢 time.sleep(0.5) #加載等待 result=driver.find_element_by_xpath('/html/body/div[3]/div/div[2]/div[2]/div[1]/div/p/span').text#總違章條數 result=int(result) a=math.ceil(result/10)#總頁數 b=result%10 #除余

讀取列表中的數據，其中扣分和罰款需要點擊'查看詳情'，從彈窗中讀取數據

result1=WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'//table[@id=’my-msg-list’]/tbody/tr['+str(j)+']/td[1]'))).textresult2=WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'//table[@id=’my-msg-list’]/tbody/tr['+str(j)+']/td[2]'))).textresult3=WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'//table[@id=’my-msg-list’]/tbody/tr['+str(j)+']/td[3]'))).textresult4=WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'//table[@id=’my-msg-list’]/tbody/tr['+str(j)+']/td[4]'))).textresult5=WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'//table[@id=’my-msg-list’]/tbody/tr['+str(j)+']/td[5]'))).textresult6=WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'//table[@id=’my-msg-list’]/tbody/tr['+str(j)+']/td[6]'))).textresult7=WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'//table[@id=’my-msg-list’]/tbody/tr['+str(j)+']/td[7]'))).textWebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'//table[@id=’my-msg-list’]/tbody/tr['+str(j)+']/td[8]/a'))).click()#查看詳情，打開彈窗time.sleep(1) #加載等待result8=WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'//form[@class=’form-horizontal’]/div[7]/span[2]'))).textresult9=WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'//form[@class=’form-horizontal’]/div[8]/span[2]'))).textresult=[result1,result2,result3,result4,result5,result6,result7,result8,result9]R.append(result)WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'//div[@class=’modal-footer ui_modal’]/button'))).click()#關閉彈窗time.sleep(0.5) #加載等待

每讀取一輛車的數據就寫入表格中
