python+selenium，使用input控件进行文件上传时click操作报错：InvalidArgumentException
背景：使用AUTOIT方式进行文件上传时，选择文件按钮，直接进行click操作时报错，原代码如下：
from selenium import webdriver import time import os wb = webdriver.Firefox() wb.get('file:///D:/1.0%E6%B5%8B%E8%AF%95%E5%AD%A6%E4%B9%A0/6.0UI%E8%87%AA%E5%8A%A8%E5%8C%96/demo.html') # 窗口最大化 wb.maximize_window() f = wb.find_element_by_id('load') f.click() os.system(r'C:\Users\yu\Desktop\upfile.exe')
报错信息：如下
1 Traceback (most recent call last): 2 File "D:\python\python-demo\UI\Firefox.py", line 10, in <module> 3 f.click() 4 File "C:\Python39\lib\site-packages\selenium\webdriver\remote\webelement.py", line 80, in click 5 self._execute(Command.CLICK_ELEMENT) 6 File "C:\Python39\lib\site-packages\selenium\webdriver\remote\webelement.py", line 633, in _execute 7 return self._parent.execute(command, params) 8 File "C:\Python39\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute 9 self.error_handler.check_response(response) 10 File "C:\Python39\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response 11 raise exception_class(message, screen, stacktrace) 12 selenium.common.exceptions.InvalidArgumentException: Message: Cannot click <input type=file> elements
解决方案：将click操作修改为鼠标事件，上传成功
action = ActionChains(wb) action.move_to_element(f).click().perform() action.release() time.sleep(3) os.system(r'C:\Users\yu\Desktop\upfile.exe') time.sleep(3)
