UnovaRPG自动程序: Selenium映像错误

Question

我正在尝试使用Selenium制作一个python程序来自动化UnovaRPG游戏。它应该做以下工作：

1)使用用户名和密码登录。

2)转到康复中心，点击“治愈”。

3)与教练"shedinja144“战斗(使用给定的链接)

4)选择指定的口袋妖怪。

( 5)在战斗中，应单击最后一次攻击，然后继续攻击。

6)然后单击最后一个口袋妖怪(第6页)的“向后映射”。

7)重复任何给定次数的步骤2-5。

这是我的代码：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("https://www.unovarpg.com/login.php")
assert "UnovaRPG" in driver.title
i=1
j=1

typeUsername = driver.find_element_by_id("username")
typePassword = driver.find_element_by_id("password")

typeUsername.send_keys("******")
typePassword.send_keys("******")
driver.find_element_by_id("buttonLogin").click()

while i<10:
    driver.get("https://www.unovarpg.com/pokemon_center.php")
    driver.find_element_by_id("healButton").click()
    driver.get("https://www.unovarpg.com/battle.php?type=autotrainer&tid=5546527")
    driver.find_element_by_xpath("/html/body/div[3]/div[2]/div[3]/div/div/div[2]/div[2]/div[8]/div[4]/div[1]/img").click()
    while j<6:
        driver.find_element_by_xpath("/html/body/div[3]/div[2]/div[3]/div/div/div[2]/div[2]/div[4]/div[6]/div[2]/ul/li[4]/a/strong").click()
        driver.find_element_by_id("continue").click()
        j+=1
    driver.find_element_by_xpath("/html/body/div[3]/div[2]/div[3]/div/div/div[2]/div[2]/div[4]/div[6]/div[2]/ul/li[4]/a/strong").click()
    driver.find_element_by_id("Back2MapButton").click()
    i+=1

以下是错误：

***Repl Closed***

错误在于无法找到口袋妖怪的映像来单击(步骤4)。我使用了从Firebug检查器复制的xcode路径。

我会很感激你的帮助。

请注意，这只是为了创造性的目的，不会被用来“欺骗”.

Answer 1

在与它交互之前，您需要使用显式地等待元素加载。：

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

element = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.XPATH, "/html/body/div[3]/div[2]/div[3]/div/div/div[2]/div[2]/div[8]/div[4]/div[1]/img"))
)
