Boto3でLambdaを起動させる

import boto3

client = boto3.client('lambda')

# Lambdaのevent変数に入れる値
query = {
	"test1": "test",
	"test2": "test"
}

# Lambdaを実行
response = client.invoke(
	FunctionName='LAMBDA_FUNCTION_NAME',
	InvocationType='RequestResponse',
	LogType='Tail',
	Payload= query
)

# レスポンスを読む
res = response['Payload'].read()
