REST API设计以检索摘要信息

问题描述:

我有一个方案,其中我有一个REST API,该API管理一个称为组"的资源. 网上论坛的概念类似于Google网上论坛中的讨论论坛.

I have a scenario in which I have REST API which manages a Resource which we will call Group. A Group is similar in concept to a discussion forum in Google Groups.

现在我有两种GET访问方法,我认为它们需要单独的表示形式.

Now I have two GET access method which I believe needs separate representations.

第一个GET访问方法检索有关组的最少信息. 给定一个 group_id ,它应该返回少量信息,例如

The 1st GET access method retrieves the minimal amount of information about a Group. Given a group_id it should return a minimal amount of information like

{ 
    group_id: "5t7yu8i9io0op",
    group_name: "Android Developers",
    is_moderated: true,
    number_of_users: 34,
    new_messages: 5,
    icon: "http://boo.com/pic.png"
}

第二种GET访问方法检索本质上更具统计性的摘要信息,例如:

The 2nd GET access method retrives summary information which are more statistical in nature like:

{ 
    group_id: "5t7yu8i9io0op",
    top_ranking_users: {
      [ { user: "george", posts: 789, rank: 1 }, 
        { user: "joel", posts: 560, rank: 2 }  ...]
    },
    popular_topics: {
      [ ... ]
    }
}

我想将这些数据访问方法分开,并且我目前正在计划这种设计:

I want to separate these data access methods and I'm currently planning on this design:

GET /group/:group_id/
GET /group/:group_id/stat

只有后者会返回有关该组的统计信息.您对此有何看法?

Only the latter will return the statistical information about the group. What do you think about this ?

我认为您的方法没有问题.由于统计信息基本上是单独的数据,因此您也可以将统计信息视为单独的资源,并提供

I don't see a problem with your approach. Since the statistics are basically separate data, you could treat the stats as a separate resource, too, providing a URI like

GET /stat/:group_id

此外,您可以交叉引用您的资源(这意味着一个组链接到相应的统计资源,反之亦然):

Additionally you can cross reference your resources (meaning a group links to the corresponding stat resource and vice versa):

GET /group/5t7yu8i9io0op

{ 
    group_id: "5t7yu8i9io0op",
    group_name: "Android Developers",
    is_moderated: true,
    number_of_users: 34,
    new_messages: 5,
    icon: "http://boo.com/pic.png",
    stats: "http://mydomain.com/stat/5t7yu8i9io0op"
}

GET /stat/5t7yu8i9io0op

{ 
    group: "http://mydomain.com/group/5t7yu8i9io0op",
    top_ranking_users: {
      [ { user: "george", posts: 789, rank: 1 }, 
        { user: "joel", posts: 560, rank: 2 }  ...]
    },
    popular_topics: {
      [ ... ]
    }
}
