从字段中获取正确的值

如何解决从字段中获取正确的值

我在 elasticsearch 上遇到了问题。 我终于可以发布到elasticsearch，但数据是用“S”值而不是实际值写入的。

当我查看我的 cloudwatch 日志时，我看到了这一点。

{
    "Records":[
    {
        "eventID":"d5d4955d706dd71348760a482f33735f","eventName":"INSERT","eventVersion":"1.1","eventSource":"aws:dynamodb","awsRegion":"us-east-1","dynamodb":{
            "ApproximateCreationDateTime":1613816980.0,"Keys":{
                "uuid":{
                    "S":"c140a68de65301465cd1cd3d97cc4107"
                }
            },"NewImage":{
                "Smsstatus":{
                    "S":"received"
                },"streetname":{
                    "S":"King tut"
                },"timestampMessage":{
                    "S":"Sat Feb 20 2021 10:29:39 GMT+0000 (Coordinated Universal Time)"
                }
            }
        }
        }
    ]
}

这是我正在使用的代码。

import os
import boto3
import requests
from requests_aws4auth import AWS4Auth

es_host = os.environ['ES_HOST']
es_index = "Metadata"
es_type = "episodes"
url = es_host + '/' + es_index + '/' + es_type + '/'

region = 'us-east-1'
service = 'es'
credentials = boto3.Session().get_credentials()
awsauth = AWS4Auth(credentials.access_key,credentials.secret_key,region,service,session_token=credentials.token)

def lambda_handler(event,context):
    print(event)
    for record in event['Records']:
        id = str(record['dynamodb']['Keys']['uuid']['S'])
        if record['eventName'] == 'REMOVE':
            res = requests.delete(url + id,auth=awsauth)
        else:
            document = record['dynamodb']['NewImage']
            res = requests.put(url + id,auth=awsauth,json=document,headers={"Content-Type": "application/json"})

我确定这是需要解决的小问题，但如果有人可以提供帮助，我不确定如何取悦。谢谢
