但我正在嘗試為我的網(wǎng)站編寫一個(gè)單元測試，該測試會(huì)遍歷所有鏈接，并在網(wǎng)站正常工作時(shí)返回“A ok”或“no go”。但我在使用該程序時(shí)遇到了問題，它無法不斷單擊站點(diǎn)導(dǎo)航欄中的鏈接。我嘗試過多次隱式等待。明確的預(yù)期條件，但頁面加載時(shí)，有一半的時(shí)間會(huì)單擊鏈接并轉(zhuǎn)到網(wǎng)站的該部分，而另一半的程序只是停止，沒有單擊任何內(nèi)容。from selenium import webdriverfrom selenium.webdriver.common.keys import Keysimport timefrom selenium.webdriver.common.by import Byfrom selenium.webdriver.support.ui import WebDriverWaitfrom selenium.webdriver.support import expected_conditions as ECfrom selenium.webdriver import ActionChainsPATH = "C:\Program Files (x86)\chromedriver.exe"drive = webdriver.Chrome(PATH)drive.get("https://www.blackhempfamily.com/")wait = WebDriverWait(drive, 10)link = wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "Why Black Hemp?")))link.click()

將是一個(gè)更好使用的標(biāo)簽。
wait.until(EC.element_to_be_clickable((By.XPATH, "//p[text()='Why Black Hemp?']")))

嘗試使用 xpath 代替，并使用要定位的元素（不可單擊），因?yàn)樗且粋€(gè)段落。這對我有用：
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver import ActionChains
PATH = "C:\Program Files (x86)\chromedriver.exe"
drive = webdriver.Chrome(PATH)
drive.get("https://www.blackhempfamily.com/")
linkWait = EC.element_to_be_located((By.XPATH, "//div/p[contains(., 'Why Black Hemp?')]"))
WebDriverWait(drive, 10).until(linkWait)
link = drive.find_element_by_xpath("//div/p[contains(., 'Why Black Hemp?')]")
link.click()

所以，花了一段時(shí)間......但是，我認(rèn)為我能夠解決這個(gè)問題。您需要執(zhí)行的操作是：
點(diǎn)擊“為什么是黑大麻？”
等待頁面停止?jié)L動(dòng)
滾動(dòng)到頁面頂部
等待頁面停止?jié)L動(dòng)
**嘗試向下滾動(dòng)以便可以
nav顯示該欄重復(fù)直到您滿意/通過“A-OK”測試
為了實(shí)現(xiàn)這一點(diǎn)，您需要導(dǎo)入以下內(nèi)容
from selenium import webdriver
from selenium.webdriver.chrome.webdriver import WebDriver as ChromeWebDriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait as DriverWait
from selenium.webdriver.support import expected_conditions as DriverConditions
from selenium.common.exceptions import WebDriverException
import time
第 1 步 - 點(diǎn)擊“為什么是黑大麻？” nav條形元素
chrome_driver.find_element(By.XPATH, "//nav[contains(@id, 'navContainer')]//p[text()='Why Black Hemp?']/../../..").click()
第 2 步 - 檢查頁面是否仍在滾動(dòng)
# Checks to see if our page is still scrolling
while is_same_position == False:
windowPosition1 = chrome_driver.execute_script("return document.body.scrollHeight;")
time.sleep(2)
windowPosition2 = chrome_driver.execute_script("return document.body.scrollHeight;")
if(windowPosition1 == windowPosition2):
is_same_position = True
final_window_position = windowPosition1
第 3 步 - 滾動(dòng)到頁面頂部
chrome_driver.execute_script("window.scrollTo(0, {0})".format((0 - final_window_position)))
第 4 步 - 檢查頁面是否仍在滾動(dòng)
# Checks to see if our page is still scrolling
while is_same_position == False:
windowPosition1 = chrome_driver.execute_script("return document.body.scrollHeight;")
time.sleep(2)
windowPosition2 = chrome_driver.execute_script("return document.body.scrollHeight;")
if(windowPosition1 == windowPosition2):
is_same_position = True
第 5 步 - 嘗試向下滾動(dòng)，直到我們的header標(biāo)簽沒有styleofvisibility: hidden
# Scrolls down until our nav bar is displayed
for scrollNum in range(10):
chrome_driver.execute_script("window.scrollTo(0, {0})".format(scrollNum * 100 + 200))
time.sleep(2)
if is_displayed(chrome_driver, "//header[contains(@style, 'visibility: hidden')]") == False:
break
第 6 步 - 重復(fù)直到您滿意為止

您正在搜索的元素不是鏈接。這是一個(gè)段落(p)。我添加了一個(gè)sleep調(diào)用以使頁面有更多的加載時(shí)間。
試試這個(gè)代碼：
time.sleep(3)
wait = WebDriverWait(drive, 10)
#link = wait.until(EC.element_to_be_clickable((By.LINK_TEXT, "Why Black Hemp?")))
link = drive.find_element_by_xpath('//*[@id="idh09fqo2label"]')
link.click()
