AWS SAM lambda 授权方 Internet 访问

Question

Just adding to aws sam cli hello world example and trying to add lambda authorizer:

MyAuthFunction:
  Type: AWS::Serverless::Function
  Properties:
    CodeUri: ./python
    Handler: auth/authorizer.lambda_handler
    Runtime: python3.8

My lambda needs to get a public key from my tenant so I need an external get call to get it:

def lambda_handler(event, context):
  ...
  print("getting pub key from", 'https://%s/pem' % os.environ['AUTH_DOMAIN'])
  pub_key = requests.get('https://%s/pem' % os.environ['AUTH_DOMAIN'])
  ... 

Every time I hit the lambda it gets timed out:

Function 'MyAuthFunction' timed out after 3 seconds

Am I missing something here? I feel like my lambda doesn't have access to the internet

Answer 1

You should increase Timeout , from default 3 seconds to whatever is required for your function to work successful (max 15 min).

For example:

MyAuthFunction:
  Type: AWS::Serverless::Function
  Properties:
    CodeUri: ./python
    Handler: auth/authorizer.lambda_handler
    Runtime: python3.8
    Timeout: 60 # one minute
