Question

为什么const不能使用enum关键字？

使用enum，rspec成功失败：

{
  "id": "https://json-schema.org/geo",
  "$schema": "https://json-schema.org/draft-06/schema#",
  "description": "unauthorized authentication",
  "type": "object",
  "required": ["error"],
  "properties": {
    "error": { "enum": ["Xinvalid credentials"] }
  }
}

Failure/Error: expect(response).to match_json_schema('api/v1/user/unauthorized_authentication')

   #/error: failed schema #/properties/error: Invalid credentials is not a member of ["Xinvalid credentials"].

   ---

   expected

   {
     "error": "Invalid credentials"
   }

   to match schema "api/v1/user/unauthorized_authentication":

   {
     "id": "https://json-schema.org/geo",
     "$schema": "https://json-schema.org/draft-06/schema#",
     "description": "unauthorized authentication",
     "type": "object",
     "required": [
       "error"
     ],
     "properties": {
       "error": {
         "enum": [
           "Xinvalid credentials"
         ]
       }
     }
   }

 # ./spec/requests/api/v1/users/authenticate_spec.rb:34:in `block (3 levels) in <main>'

如果我将此enum更改为const（或constant）（不带括号）不会失败，为什么？

{
  "id": "https://json-schema.org/geo",
  "$schema": "https://json-schema.org/draft-06/schema#",
  "description": "unauthorized authentication",
  "type": "object",
  "required": ["error"],
  "properties": {
    "error": { "const": "Xinvalid credentials" }
  }
}

测试还可以，但是根据docs应该失败

[POST] /api/v1/users/authenticate
  User tries to authenticate with invalid redentials
    returns an invalid credentials message
    behaves like unauthorized endpoint
      returns 403 http status code
      behaves like json header
        returns content-type: application/json header

谢谢

const关键字在Rspec json_matchers中不起作用
