/opt/chromedriver 意外退出。状态代码为 127\n

Question

我正在 aws lambda 中使用 selenium 运行 python 脚本。我创建了 2 层，1 层用于 selenium，1 层用于 chromedriver 和 headless-chromium。执行时我收到错误

Response
{
  "errorMessage": "Message: Service /opt/chromedriver unexpectedly exited. Status code was: 127\n",
  "errorType": "WebDriverException",
  "stackTrace": [

  ]
}

我使用的是Python 3.8版本。从https://github.com/adieuadieu/serverless-chrome/releases?page=1下载最新版本 v1.0.0-57 headless-chromium 此 chromium 的 ChromeDriver 版本是https://chromedriver.storage.googleapis.com/index .html?路径=86.0.4240.22/

我正在使用本教程部署到 lambda https://dev.to/awscommunity-asean/creating-an-api-that-runs-selenium-via-aws-lambda-3ck3 本教程使用 python3.6 但我想使用较新的版本。

在这里发布我的 lambda 函数

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

def lambda_handler(event, context):
    print("Launching browser")
    options = webdriver.ChromeOptions()
    options.add_argument('--headless')
    options.add_argument("--no-sandbox")
    options.add_argument("--log-level=1")
    options.add_argument("--start-maximized")
    options.binary_location = "/opt/headless-chromium"
    chromedriver_path = "/opt/chromedriver"
    driver = webdriver.Chrome(options=options, executable_path=chromedriver_path)

    driver.get('https://www.google.com/')

    driver.close();
    driver.quit();

    response = {
        "statusCode": 200,
        "body": "Selenium Headless Chrome Initialized"
    }

    return response

提前致谢。

Answer 1

根据这个答案，Chrome 需要安装额外的库才能工作。通过在这篇 AWS博客文章之后为 lambda 创建一个 docker 容器，我能够让 selenium 在 AWS lambda 上工作。
