pass json file to serverless lambda

Question

I created a simple api that reads from json file (passed as input) a key and checks in a database if is present if I test it locally

 serverless invoke local --function getVin --path input/input_212.json

works

how can I test with curl once deployed on AWS?

I am trying with

curl --request GET 'https://xxxx.execute-api.us-east-1.amazonaws.com/dev/vin' --header 'content-type: text/plain' --data-raw  @input.json

or

curl -H "Content-Type: application/json" -X GET -d '{
    "CustomerId": 213,
    "VIN": "WDBJF65J1YB039213"
    }' https://xxxxx.execute-api.us-east-1.amazonaws.com/dev/vin

but does not work with this error

curl -H "Content-Type: application/json" -X GET -d '{
"CustomerId": 213,
"VIN": "WDBJF65J1YB039213"
}' https://xxxxx.execute-api.us-east-1.amazonaws.com/dev/vin

the input json is something like this

{
    "key1": 1,
    "key2": "abcdefg"
}

`but does not work` what error does it return? – tianz Apr 22 '21 at 20:00 — tianz, Apr 22 '21 at 20:00

Are you sure that this is a GET request? You are passing JSON data to the API which means that you will have to make sure that you are using POST request in your CURL request, in the serverless application that you have written and also in the serverless config file. Once you have that figured, the following CURL request should work:

curl --request POST \
  --url https://xxxxx.execute-api.us-east-1.amazonaws.com/dev/vin \
  --header 'Content-Type: application/json' \
  --data '{
    "CustomerId": 213,
    "VIN": "WDBJF65J1YB039213"
}'

The method is implemented as a get and the json is an input file used to check if the data inside the json is stored in the database. I also have a post where I still pass a json that is then stored in the database. My problem was figuring out how to call it from terminal — bruvio, Apr 25 '21 at 16:07
