MSON 到 JSON-Schema "One of" 问题

Question

我尝试用 ApiBlueprint MSON 表示法描述具有可变部分的对象。这是 ApiBlueprint 中的简单代码：

 FORMAT: 1A

# Test API

## Services [/Service/{id}]

### GET Service info [GET]


+ Request (application/json)

    + Headers

            Authorization: JWT <token>

+ Response 200 (application/json)

    + Attributes (array[ServiceResource], fixed)



# Data Structures

## Resource (object)
### Properties

+ id: `a6vhAo3FG` (string, fixed)
+ created_at: `2016-07-01T15:11:09.553Z` (string, required)
+ updated_at: `2017-11-22T08:07:55.002Z` (string, required)


## Service (object)

### Properties
+ type: tcp_service (string, required)
- One Of
    - config (TcpService, required)
    - config (IcmpService, required)


## ServiceResource (Resource)
### Properties

- Include Service

## TcpService (object)

### Properties

+ port: `80` (number, required) 
+ request_str: `HEAD` (string, required)
+ expect_response_str: `200 OK` (string, required)

## IcmpService (object)

### Properties

+ timeout_ms: `1000` (number, required)
+ packet_size_bytes: `1000` (number, required)
+ ttl: `128` (number, required)

它在 apiary.io 中完美呈现，但在 https://json-schema-validator.herokuapp.com 中验证生成的 Json 模式报告错误：

[ {
  "level" : "error",
  "schema" : {
    "loadingURI" : "#",
    "pointer" : "/items"
  },
  "instance" : {
    "pointer" : "/0"
  },
  "domain" : "validation",
  "keyword" : "additionalProperties",
  "message" : "object instance has properties which are not allowed by the schema: [\"config\"]",
  "unwanted" : [ "config" ]
} ]

也许我做错了什么？

有没有什么方法可以在 MSON 中描述对象数组，其中对象具有给出正确 JSON 架构的变体部分？

我相信您正在寻找 fixed-type type attribute。 fixed 表示值是固定的，不能是提供的示例值以外的任何值。当您使用 fixed-type 时，表示类型是固定的，但值不是。

+ Attributes (array[ServiceResource], fixed-type)
