頁面結構

網易登入頁

 

 

 

 

 

 

 

登入成功后的頁面代碼

 

 

 

代碼

'''
#我們對網頁的操作沒有報錯不代表自動化沒有問題
#此時需要通過頁面返回的信息做一個判斷，來做人工的定位  
'''
from selenium import webdriver
from selenium.webdriver.common.by import By
import time
driver = webdriver.Chrome()
driver.get("https://www.126.com/")
time.sleep(4)

print('Before login............')
title = driver.title
print(title)
nowURL = driver.current_url
print(nowURL)

#這是為了先卻換到運行模塊，不然會定位不到元素
fname =driver.find_element(By.XPATH,'/html/body/div[2]/div[3]/div[1]/div/div[4]/div[1]/div[1]/iframe')
driver.switch_to.frame(fname)

#百度輸入框輸入內容
driver.find_element(By.XPATH,"//input[@name='email']").clear()
driver.find_element(By.XPATH,"//input[@name='email']").send_keys("username")
driver.find_element(By.NAME,"password").clear()
driver.find_element(By.NAME,"password").send_keys("password")
driver.find_element(By.ID,"dologin").click()
#driver.find_element(By.CSS_SELECTOR,"[data-loginname='loginEmail']")

time.sleep(5)

print('After login............')
title = driver.title
print(title)
nowURL = driver.current_url
print(nowURL)

#此種方法不能點出text
# user = driver.find_elements(By.ID,'spnUid')
#后面的這3種方法都可以  取登入頁面后用戶賬號信息來驗證自動化是否正常
# user =driver.find_element(By.XPATH,'//*[@id="spnUid"]').text
# user =driver.find_element(By.XPATH,'/html/body/header/div[1]/ul[1]/li[1]/a//*[@id="spnUid"]').text
user =driver.find_element(By.CSS_SELECTOR,"[id='spnUid']").text
print(user)

driver.quit()

 

異常

打印結果找不到text

 

解決辦法

通過瘋狂百度，嘗試了text，getAttribute通通失敗。一位熱心網友的回復救了我，他懷疑是元素定位不准確導致的。於是我只定位了第一個元素，.text獲取成功。

user =driver.find_element(By.XPATH,'/html/body/header/div[1]/ul[1]/li[1]/a//*[@id="spnUid"]').text
