python - 来自 Python : No module named lambda_function 的 AWS 错误

Question

我正在创建一个 AWS Lambda python 部署包。我正在使用一个外部依赖请求。我使用 AWS documentation 安装了外部依赖项.下面是我的 Python 代码。

import requests

print('Loading function')

s3 = boto3.client('s3')


def lambda_handler(event, context):
    #print("Received event: " + json.dumps(event, indent=2))

    # Get the object from the event and show its content type
    bucket = event['Records'][0]['s3']['bucket']['name']
    key = urllib.unquote_plus(event['Records'][0]['s3']['object']['key']).decode('utf8')
    try:
        response = s3.get_object(Bucket=bucket, Key=key)
        s3.download_file(bucket,key, '/tmp/data.txt')
        lines = [line.rstrip('\n') for line in open('/tmp/data.txt')]
        for line in lines:
            col=line.split(',')
            print(col[5],col[6])
        print("CONTENT TYPE: " + response['ContentType'])
        return response['ContentType']
    except Exception as e:
        print(e)
        print('Error getting object {} from bucket {}. Make sure they exist and your bucket is in the same region as this function.'.format(key, bucket))
        raise e

创建 Zip 项目目录的内容并上传到 lambda(压缩目录内容，而不是目录)。当我执行该函数时，我得到了下面提到的错误。

Answer 1

错误是由于 lambda 函数的文件名。在创建 lambda 函数时，它会要求 Lambda 函数处理程序。您必须将其命名为 Python_File_Name.Method_Name。在这种情况下，我将其命名为 lambda.lambda_handler(lambda.py 是文件名)。

请在快照下方找到。
