Python Selenium报'bool' object is not callable及验证码定位报错求解

两个报错的根因 #

• 第一个TypeError: 'bool' object is not callable报错：WebDriverWait的until方法要求传入可调用的判断逻辑，你直接传入了recaptchaSolved.is_displayed()的执行结果（布尔值），不符合参数要求。
• 第二个NoSuchElementException报错：你在验证码刚加载完成时就立刻查找包含Solved文本的元素，此时自动验证插件还没完成校验，对应的标识元素还没有生成，自然找不到。同时find_element_by_partial_link_text仅能匹配<a>标签的文本，若插件生成的Solved提示不是链接类型，也会匹配失败。

修复步骤 #

1. 首先补充导入Selenium的显式等待依赖模块：

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

2. 修改验证码判断逻辑：先判断页面是否存在验证码，存在的话再用显式等待等待验证完成标识出现，不要提前查找未生成的元素。
3. 额外优化：原代码读取账号时循环里固定取第1行的账号密码，建议改为取当前循环行的内容。

修改后的完整代码 #

## necessary import codes
from selenium import webdriver
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
import time
import xlrd
import random

## random waiting time
random_Get_Time = random.randint(1,5)

## importing data file
data_File_Path = "C:/Users/doguk/Desktop/Python/DataFile.xls"

## targeting the data
dataFile = xlrd.open_workbook(data_File_Path)
accountInfo = dataFile.sheet_by_name("account_Ids_And_Passwords")
usernameCount = accountInfo.nrows
passwordCount = accountInfo.ncols
# 修复原代码固定取第1行账号的问题，如需多账号循环可把后续逻辑缩进放到for循环内
for curr_row in range(1, usernameCount):
    username = accountInfo.cell_value(curr_row, 0)
    password = accountInfo.cell_value(curr_row, 1)

## setting up recaptcha solver plugin to browser
recaptcha_Solver_Plugin_Path = "C:/Users/doguk/Desktop/Python/plugin.zip"

## adding recaptcha solver plugin to browser
recaptchaSolverAddOptions = webdriver.ChromeOptions()
recaptchaSolverAddOptions.add_extension(recaptcha_Solver_Plugin_Path)

## browser driver code
chrome_Driver_Path = "C:/Users/doguk/Desktop/Python/chromedriver"
driver = webdriver.Chrome(chrome_Driver_Path, options=recaptchaSolverAddOptions)

## enter the browser
driver.get("**URL**")
time.sleep(random_Get_Time)

## fullscreen code
driver.maximize_window()

## filling account infos
login_Form_Username = driver.find_element_by_id('username')
login_Form_Username.send_keys(username)
time.sleep(random_Get_Time)
login_Form_Password = driver.find_element_by_id('password')
login_Form_Password.send_keys(password)

## 修复后的验证码等待逻辑
# 先判断是否存在验证码，避免没有验证码时直接报错
recaptcha_list = driver.find_elements_by_class_name('g-recaptcha')
if len(recaptcha_list) > 0 and recaptcha_list[0].is_displayed():
    # 显式等待最多120秒，直到Solved标识出现，可根据插件实际验证速度调整超时时间
    WebDriverWait(driver, 120).until(
        EC.visibility_of_element_located((By.XPATH, "//*[contains(text(),'Solved')]"))
    )
else:
    time.sleep(random_Get_Time)

## log in to platform
login_Button = driver.find_element_by_class_name('btn')
login_Button.click()
time.sleep(random_Get_Time)

## logout from driver
driver.quit()

逻辑说明 #

• 用find_elements查找验证码元素，返回空列表就说明页面没有验证码，直接走短等待逻辑即可
• 显式等待超时时间设置为120秒，足够插件完成自动验证，验证完成后会立刻执行后续登录操作，比固定休眠110秒效率更高
• 如果你的插件完成验证后的提示不是Solved文本，可以手动打开页面看插件验证完成后的元素内容，替换XPATH里的匹配文本即可。
