下面我们快速实现一套RESTFUL的mock接口。

创建数据文件

新建文本文件，名为db.json，内容如下:

{
  "posts": [
    { "id": 1, "title": "json server入门", "author": "乙醇" }
  ],
  "comments": [
    { "id": 1, "body": "some comment", "postId": 1 }
  ],
  "profile": { "name": "typicode" }
}

运行mock server

在命令行中运行

json-server --watch db.json

验证

在浏览器中访问http://localhost:3000/posts/1，这时候应该可以返回

{ "id": 1, "title": "json server入门", "author": "乙醇" }

路由

根据上面的data文件，默认情况下json-server会生成下面一些路由

复数路由

GET    /posts
GET    /posts/1
POST   /posts
PUT    /posts/1
PATCH  /posts/1
DELETE /posts/1

GET    /comments
GET    /comments/1
POST   /comments
PUT    /comments/1
PATCH  /comments/1
DELETE /comments/1

单数路由

GET    /profile
POST   /profile
PUT    /profile
PATCH  /profile

潜规则

• POST, PUT, PATCH 或DELETE真的会对db.json文件产生影响，比如会保存新增的数据
• 请求body中需要传json字符串，比如{"name": "Foobar"}
• POST, PUT 或 PATCH请求headers中必须包括Content-Type: application/json
