Json 使用 Lambda 从 S3 读取数据

我在AWS上的S3存储桶中存储了一系列json文件.

我希望使用AWS lambda python服务来解析此json，并将解析结果发送到AWS RDS MySQL数据库.

我有一个稳定的python脚本，用于解析和写入数据库.我需要lambda脚本来迭代json文件(在添加它们时).

Each json file contains a list, simple consisting of results = [content]

In pseudo-code what I want is:

1. Connect to the S3 bucket (jsondata)
2. Read the contents of the JSON file (results)
3. Execute my script for this data (results)

I can list the buckets I have by:

import boto3

s3 = boto3.resource('s3')

for bucket in s3.buckets.all():
    print(bucket.name)

给予:

jsondata

But I cannot access this bucket to read its results.

似乎没有read或load函数.

我希望像这样

for bucket in s3.buckets.all():
   print(bucket.contents)

编辑

我有点误会.lambda必须自己下载文件，而不是在S3中读取文件.

从here开始，您似乎必须给lambda一个下载路径，它可以从该路径访问文件本身

import libraries

s3_client = boto3.client('s3')

def function to be executed:
   blah blah

def handler(event, context):
    for record in event['Records']:
        bucket = record['s3']['bucket']['name']
        key = record['s3']['object']['key'] 
        download_path = '/tmp/{}{}'.format(uuid.uuid4(), key)
        s3_client.download_file(bucket, key, download_path)
