Using boto to invoke lambda functions how do I do so asynchronously?

Question

SO I\'m using boto to invoke my lambda functions and test my backend. I want to invoke them asynchronously. I have noted that \"invoke_async\" is deprecated and should not

Answer 1

The following are a python function that accepts lambda-function-Name to invoke and payload to send to that function.

It invokes the lambda function by boto3 client.

import boto3, json, typing

def invokeLambdaFunction(*, functionName:str=None, payload:typing.Mapping[str, str]=None):
    if  functionName == None:
        raise Exception('ERROR: functionName parameter cannot be NULL')
    payloadStr = json.dumps(payload)
    payloadBytesArr = bytes(payloadStr, encoding='utf8')
    client = boto3.client('lambda')
    response = client.invoke(
        FunctionName=functionName,
        InvocationType="RequestResponse",
        Payload=payloadBytesArr
    )
    return response

And usage:

if __name__ == '__main__':
    payloadObj = {"something" : "1111111-222222-333333-bba8-1111111"}
    response = invokeLambdaFunction(functionName='myLambdaFuncName',  payload=payloadObj
    print(f'response:{response}')
