After I checked the document of AVS migration (https://developer.amazon.com/public/solutions/alexa/alexa-voice-service/docs/migration-guide)
I made a request after ssl connect done, using "nghttp2_submit_request" which will send a HEADER frame.The data like this:
:method: GET
:scheme: https
:path: /v20160207/directives
authorization: Bearer {{access_token}}
And I found this:
if {{access_token}} is invalid, it would response a json-format string :
{"header":{"namespace":"System","name":"Exception","messageId":"83e5e334-5470-43c4-86d7-be5cbc19a4bd"},"payload":{"code":"UNAUTHORIZED_REQUEST_EXCEPTION","description":"Unable to authenticate the request. Please provide a valid authorization token."}}
but if {{access_token}} is valid , it will response a GOAWAY frame.
So . What should I going to do now? Can any one help me out? It would be a great appreciation```
