[英]Write out Boto3 Response in JSON Object and Upload to S3 in AWS Lambda Function
I have a Python 3.6 AWS Lambda Function I am building out to query Cost Explorer, and a few other services. 我有一个Python 3.6 AWS Lambda函数,我正在构建该函数以查询Cost Explorer和其他一些服务。 I want to write out the string response I am returning into a JSON object I can either upload to S3 or into DynamoDB.
我想写出返回到JSON对象的字符串响应,我可以将其上传到S3或DynamoDB中。
A working example of the Function is below 该功能的工作示例如下
import boto3
def handler(event,context):
client = boto3.client('ce')
response = client.get_cost_forecast(
TimePeriod={
'Start': '2019-06-01', ## Start must be one day after creation date of function
'End': '2020-07-01'
},
Metric='UNBLENDED_COST',
Granularity='MONTHLY',
PredictionIntervalLevel=90 ## 51 - 99 Range
)
return str (response)
That returns just fine in the console, now I tried this to put the Response into the Body of an object I wanted to write into S3 在控制台中返回的效果很好,现在我尝试将响应放入要写入S3的对象的主体中
import boto3
def handler(event,context):
client = boto3.client('ce')
s3 = boto3.resource('s3')
object = s3.Object('my-bucket', 'my/path/object.json')
response = client.get_cost_forecast(
---ce python stuff---
object.put(Body=response)
return str (response)
That is not working as expected, and I am getting this error from CloudWatch 这无法正常工作,我从CloudWatch收到此错误

I thought I could just stuff that into the object and write it out. 我以为我可以将其塞入对象并将其写出来。 Is there a better way to do what I am trying to do?
有没有更好的方法来做我想做的事情?

Body (bytes or seekable file-like object) -- Object data.
正文(字节或可搜索的类似文件的对象)-对象数据。
So try sth like Body=json.dumps(response).encode()
所以尝试像
Body=json.dumps(response).encode()
Your response
is a dict
object 您的
response
是dict
对象
