在这个具体案例中,我应该如何设计我的 RESTful API?

How should I design my RESTful API in this concrete case?

我正在用 Loopback.io 构建一个 API,我一直在思考我应该如何设计一些端点。 要了解上下文:

a Person hasMany Groups,
a Group hasMany People (and one of them is the admin),
a Member is the "Through" model for Person and Group,
a Group hasMany Sessions.

现在我有 (A):

  1. /人
  2. /人物/{id}/群组
  3. /组
  4. /组/{id}/会话

这是Loopback生成的API。 2 和 3 是 "repeated" 端点,但是 2 创建了一个 Member 实例而 3 没有。

选项 B:

  1. /人
  2. /人物/{id}/群组
  3. /People/{id}/Groups/{groupId}/Sessions

选项 C:

  1. /人
  2. /组
  3. /组/{id}/会话

我想知道哪种方法最好,A 解决方案是否足够好。 非常感谢。

选择最接近选项 C 的内容:

/people
/people/{person_id}
/groups
/groups/{group_id}
/sessions
/sessions/{session_id}

你的资源看起来像这样:

GET /people/1
{
  "person_id": 1,
  "groups": [
    "/groups/5",
    "/groups/7"
  ]
}

GET /groups/5          (Option 1 - if every group has exactly one admin)
{
  "group_id": 5,
  "admin": "/people/1",
  "members": [
    "/people/1",
    "/people/4",
    "/people/5"
  ],
  "sessions": [
    "/sessions/2",
    "/sessions/3"
  ]
}

GET /groups/5          (Option 2 - if groups can have any number of admins)
{
  "group_id": 5,
  "members": [
    {
      "person": "/people/1",
      "is_admin": true,
    },
    {
      "person": "/people/4",
      "is_admin": false
    },
    {
      "person": "/people/5",
      "is_admin": false
    }
  ],
  "sessions": [
    "/sessions/2",
    "/sessions/3"
  ]
}

GET /sessions/3
{
  "session_id": 3,
  "group": "/groups/5"
}

我的建议始终是避免嵌套 URI,除非有很好的理由支持这样做。
