How to pass multiple get parameters in my lambda function?

Question

I have multiple GET parameters so how should i pass in lambda function and how would my serverless.yml look like.Currently below is the configuration

serverless.yml

myFunc:
    handler: com.mcm.in.MyHandler
    events:  
     - http:
         path: user
         method: get
         cors: true 

Request:/mylist?page=1&size=10&filter=userId=abc&sort=-userId&version=1554304254262

Also how should i call in sls invoke local?

I have tried without the params,It's not working in serverless

You can create a request template that will map your request contents using the parameters, as noted in the documentation. Your function will look something like this (if you want to take in the page parameter for example:

myFunc:
    handler: com.mcm.in.MyHandler
    events:
     - http:
         path: user
         method: get
         cors: true
         integration: lambda
         request:
             template:
                 application/json: '{ "page" : "$input.params(''page'')" }'

I have created the request template this way for passing multiple parameters in URL

template:
application/json: '{ "userid":"$input.params(''userid'')","activityid":"$input.params(''activityid'')"}'

Here is the full code

functions:
  hello:
    handler: handler.hello
    events:
      - http:
          path: /
          method: get
  likes:
    handler: handler.likes
    events:
      - http:
          path: /likes
          method: get
          integration: lambda
          reqValidatorName: xMyRequestValidator
          request:
            passThrough: NEVER
            parameters:
              querystrings:
                userid: true
                activityid:true
            template:
              application/json: '{ "userid":"$input.params(''userid'')","activityid":"$input.params(''activityid'')"}'
          response:
            headers:
              Content-Type: "'application/json'"
