问题描述
我想知道为什么我的项目可以在本地运行，但在我的帐户中不能作为基于图像的 lambda 函数？
以下我在本地执行的命令：
docker build -t lambda-repository .
docker run -p 9001:8080 lambda-repository:latest
在另一个终端：
curl -XPOST "http://localhost:9001/2015-03-31/functions/function/invocations" -d '{}'
结果：
"Google"%
我的 AWS 账户中发生的情况：
错误：

解决方法
这不是解决方案
我在 lambda zip 中使用了这种方式。但也许会给你更多提示。
当您运行 chromedriver --verseion 时（我认为它应该是 chromedriver --version）意味着在本地运行。
所以你应该在 lambda_function.handler 中输入 os.system('<chromedriver_path>/chromedriver --version')。
喜欢executable_path。
并且您需要设置options.binary_location。
我不确定您是否也需要 def handler(event,context):
os.system('/usr/bin/chromedriver --version')
options = Options()
options.add_argument('--headless')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--disable-gpu')
options.add_argument("window-size=1280,1024")
options.binary_location = "/usr/bin/google-chrome"
url = 'http://www.google.com'
driver = webdriver.Chrome(executable_path="/usr/bin/chromedriver",options=options)
driver.get(url)
text = driver.title
return text
。
const conference = await mysqlHelper.query(conferenceSql);
// select query
const time = conference[0].created_datetime
// I wonder how to get the timezone from this time variable here.
console.log(time)
// console.log returns '2021-02-23T01:30:00.000Z' to the terminal
在您成功使用 chrome88 启动 Python3.8 后，我希望分享如何工作。
