使用Python上传文件至编码转换网站失败，报ElementNotInteractableException

我需要批量将本地文件上传到编码转换网站，转换为SHIFT_JIS编码，但执行代码时在input_file.send_keys(path)行报错，提示元素无法交互。

原代码 #

driver = webdriver.Edge()
driver.get('https://www.freeformatter.com/convert-file-encoding.html')
for path in x_paths[8745:]:


    input_file = WebDriverWait(driver, 10).until(EC.presence_of_element_located((by.CLASS_NAME, 'form-control')))
    input_file = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((by.CLASS_NAME, 'input_file')))
    input_file.send_keys(path)
    target_encoding = Select(driver.find_element(by.NAME, 'targetEncoding'))
    target_encoding.select_by_value('SHIFT_JIS')

    download_btn = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((by.ID, 'convertBtn')))
    download_btn.click()

    sleep(3)

解决方法 #

• 定位正确的文件上传元素：网站视觉上的上传按钮通常是装饰用的，真正接收文件的是隐藏的<input type="file">元素，直接定位该元素：

  input_file = WebDriverWait(driver, 20).until(EC.presence_of_element_located((by.XPATH, '//input[@type="file"]')))
  

• 移除冗余定位代码：删除第一行input_file = WebDriverWait(driver, 10).until(EC.presence_of_element_located((by.CLASS_NAME, 'form-control')))，避免变量被无效覆盖。
• 重置页面状态：每次转换完成后刷新页面，清除残留的文件信息，确保下一次上传环境干净：

  driver.refresh()
  

修改后的完整代码：

driver = webdriver.Edge()
driver.get('https://www.freeformatter.com/convert-file-encoding.html')
for path in x_paths[8745:]:
    # 定位真正的文件上传input
    input_file = WebDriverWait(driver, 20).until(EC.presence_of_element_located((by.XPATH, '//input[@type="file"]')))
    input_file.send_keys(path)
    
    # 选择目标编码
    target_encoding = Select(driver.find_element(by.NAME, 'targetEncoding'))
    target_encoding.select_by_value('SHIFT_JIS')
    
    # 点击转换按钮
    download_btn = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((by.ID, 'convertBtn')))
    download_btn.click()
    
    # 等待下载完成后刷新页面
    sleep(5)
    driver.refresh()
