Example AWS example example in python?

The first time I'm trying to use AWS. I need to integrate AWS Polish with an asterisk for text to speech.

here is an example of code i written to convert text to speech

from boto3 import client import boto3 import StringIO from contextlib import closing polly = client("polly", 'us-east-1' ) response = polly.synthesize_speech( Text="Good Morning. My Name is Rajesh. I am Testing Polly AWS Service For Voice Application.", OutputFormat="mp3", VoiceId="Raveena") print(response) if "AudioStream" in response: with closing(response["AudioStream"]) as stream: data = stream.read() fo = open("pollytest.mp3", "w+") fo.write( data ) fo.close()

I get the following error.

 Traceback (most recent call last): File "pollytest.py", line 11, in <module> VoiceId="Raveena") File "/usr/local/lib/python2.7/dist-packages/botocore/client.py", line 253, in _api_call return self._make_api_call(operation_name, kwargs) File "/usr/local/lib/python2.7/dist-packages/botocore/client.py", line 530, in _make_api_call operation_model, request_dict) File "/usr/local/lib/python2.7/dist-packages/botocore/endpoint.py", line 141, in make_request return self._send_request(request_dict, operation_model) File "/usr/local/lib/python2.7/dist-packages/botocore/endpoint.py", line 166, in _send_request request = self.create_request(request_dict, operation_model) File "/usr/local/lib/python2.7/dist-packages/botocore/endpoint.py", line 150, in create_request operation_name=operation_model.name) File "/usr/local/lib/python2.7/dist-packages/botocore/hooks.py", line 227, in emit return self._emit(event_name, kwargs) File "/usr/local/lib/python2.7/dist-packages/botocore/hooks.py", line 210, in _emit response = handler(**kwargs) File "/usr/local/lib/python2.7/dist-packages/botocore/signers.py", line 90, in handler return self.sign(operation_name, request) File "/usr/local/lib/python2.7/dist-packages/botocore/signers.py", line 147, in sign auth.add_auth(request) File "/usr/local/lib/python2.7/dist-packages/botocore/auth.py", line 316, in add_auth raise NoCredentialsError botocore.exceptions.NoCredentialsError: Unable to locate credentials

I want to provide the credentials directly in this script so that I can use this in the asterisk system application.

UPDATE: created a ~ / .aws / credentials file with the contents below

 [default] aws_access_key_id=XXXXXXXX aws_secret_access_key=YYYYYYYYYYY

now for my current login user, its work is fine, but for asterisk PBX it does not work.

Your code works great for me!

The last line says:

 botocore.exceptions.NoCredentialsError: Unable to locate credentials

Therefore, it cannot authenticate against AWS.

If you run this code on an Amazon EC2 instance, the easiest method is to assign the IAM role to the instance when it starts (you cannot add it later). This will automatically assign credentials that can be used by the application running on the instance — no code changes are required.

Alternatively, you can obtain the IAM passkey and secret key for your IAM user and save these credentials in a local file using the aws configure command.

Bad practice is to enter credentials in the source code, as they can become compromised.

Note that the pbx asterisk is usually run under the asterisk user.

So, you set authentication for this user, not root.

You can do this using speech synthesis too with a simple command. https://blog.pixiebytez.com/2019/04/speaking-texts.html In addition, it will rename the object to S3, so it would be useful if you convert thousands of files by putting the script in a loop.
