这是我现在正在尝试调试的代码。它使用 selenium chrome webdriver 和 python 3.8.

获取图像并通过自动反向 google 图像搜索运行它。

它给我一个错误详细信息：

backend\search_api.py", line 68, in upload_image self.upload_dialog AttributeError: 'searcher' object has no attribute 'upload_dialog'

我对使用 python 和 selenium 比较陌生，所以任何指点或建议将不胜感激:)

谢谢

编辑：看起来你已经部分工作了。由于我的评分很低，我不能评论，所以我在代码解决方案下面提出问题。

这是一个通过 Google 搜索 Selenium 反向图像的工作示例：

from selenium import webdriver
import os
import time

# Using Chrome to access web
driver = webdriver.Chrome(executable_path=os.path.abspath("chromedriver"))

try:
    # Open the website
    driver.get('https://images.google.com/')

    # Find cam button
    cam_button = driver.find_elements_by_xpath("//div[@aria-label=\"Search by image\" and @role=\"button\"]")[0]
    cam_button.click()

    # Find upload tab
    upload_tab = driver.find_elements_by_xpath("//*[contains(text(), 'Upload an image')]")[0]
    upload_tab.click()

    # Find image input
    upload_btn = driver.find_element_by_name('encoded_image')
    upload_btn.send_keys(os.getcwd()+"/image.png")

    time.sleep(10)

except Exception as e:
    print(e)

driver.quit()

另外请问，运行open_image_dialog之前运行宁upload_dialog为什么不这样呢？

def upload_image(self, path):
        self.__open_image_dialog()
        self.upload_dialog.send_keys(self.image_dir + "/" + path)
