是否可以在服务器上托管selenium应用程序？

Question

描述：

您好，我在 Streamlit 界面的帮助下创建了一个 Selenium 应用程序，它可以根据用户的需要进行交互和更改。该应用程序本身工作得很好，没有任何问题，此外，所有需要安装的软件包都添加到

requirements.txt

文件中。所以根本没有包裹问题。

问题：

问题是当我在 selenium 或任何其他网络服务器（例如 GitHub Codespace）上上传应用程序时，该应用程序无法运行。错误是由这一行生成的：

driver = webdriver.Chrome()

尝试过的解决方案：

我尝试下载 chrome 驱动程序并将其放入工作目录中并使用

external_path = "./chromedriver.exe"

参数，但没有运气。我愿意接受任何建议，谢谢。

代码片段：

    driver = webdriver.Chrome()
    
    driver.get(f'https://www.airbnb.com{"" if location == f"I{comma}m flexible" else f"/s/{location}"}/homes?tab_id=home_tab&refinement_paths%5B%5D=%2Fhomes&price_filter_input_type=0&channel=EXPLORE&date_picker_type=calendar&source=structured_search_input_header&search_type=filter_change&price_filter_num_nights=6&checkin={check_in_date}&checkout={check_out_date}{f"&adults={adults_count}" if adults_count > 0 else ""}{f"&children={children_count}" if children_count > 0 else ""}{f"&infants={infants_count}" if infants_count > 0 else ""}{f"&pets={pets_count}" if pets_count > 0 else ""}&flexible_trip_lengths%5B%5D={"one_week" if additional_search_filters == False else stay}{f"&max_price={max_price}" if additional_search_filters else ""}{f"&min_price={min_price}" if additional_search_filters and min_price > 10 else ""}')

首先确保您已经安装了合适版本的ChromeDriver（不带GUI）。然后，尝试像这样配置您的驱动程序：

from selenium.webdriver.chrome.options import Options

# Set Chrome options for headless mode
chrome_options = Options()
chrome_options.add_argument("--headless")

# Initialize Chrome WebDriver with options
driver = webdriver.Chrome(executable_path=chrome_driver_path, options=chrome_options)
