Question

我正在设置一个python脚本，以访问货运公司的网站并输入跟踪号，并获取装运和交货日期，我在硒current_url方法上遇到了麻烦。我拥有的代码打开了初始浏览器窗口，输入了跟踪号，并转到了发货状态页面，但是在结果页面上找不到表格项。最初，我认为这是我查找表格项的方式，但是我发现结果页面的URL仍然与我开始使用的初始URL相同。我什至添加了一个隐式等待时间，以确保页面已加载并且仍然保持不变。这是我的代码：

我认为在结果页上查找table元素仍然存在问题，但是直到我确定自己是否在搜索正确的url时，我才能确定，因此我需要首先解决该问题。任何帮助将不胜感激。

谢谢最高

您应该接受Jens Dibbern的解决方案，但只是想指出，一旦您的网址传入，您还可以使用熊猫来提取该表进行解析：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
import pandas as pd


driver = webdriver.Chrome()
driver.get("http://www.dovelogistics.com/track-shipment/")

elem = driver.find_element_by_name("txtInputNo")
elem.clear()
elem.send_keys("224893")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source

driver.implicitly_wait(5)

driver.switch_to.window(driver.window_handles[1])
resultsPage = driver.current_url
driver.get(resultsPage)

html = driver.page_source

tables = pd.read_html(html)
table = tables[5]

driver.close()

输出：

print (table)
                        0                                                  1

该网站将打开另一个窗口。您必须切换到该窗口。他们不止一次使用表ID标记。这应该有帮助：

driver = webdriver.Chrome()
driver.get('http://www.dovelogistics.com/track-shipment/')
elem = driver.find_element_by_name("txtInputNo")
elem.clear()
elem.send_keys("224893")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source

driver.switch_to.window(driver.window_handles[1])
print(driver.current_url)

elem = driver.find_elements_by_id("Table1")
print (elem)

driver.close()

您必须处理其嵌套表和重复的id标签。
