我们在测试功能的时候，往往需要后台的数据，如果后台的数据没有的时候，我们可以用json-server来实现快速实现简单的数据模拟！
- 使用前提
安装node.js,使用node -v测试安装是否成功 - npm install -g json-server 全局安装json-server
- 在随意一个文件夹新建db.json
{
"users": [
{ "name": "Henry", "phone": "13260582198", "email": "[email protected]", "id": "1", "age": "30", "compandyId": "1" },
{ "name": "Emily", "phone": "13260582198", "email": "[email protected]", "id": "2", "age": "5", "compandyId": "2" },
{ "name": "lili", "phone": "13260582198", "email": "[email protected]", "id": "3", "age": "16", "compandyId": "3" },
{ "name": "fv", "phone": "13260582198", "email": "[email protected]", "id": "4", "age": "18", "compandyId": "3" },
{ "name": "cons", "phone": "13260582198", "email": "[email protected]", "id": "5", "age": "29", "compandyId": "1" }
],
"companies":[{
"id":"1",
"name":"apple",
"description":"Apple is good"
},
{
"id":"2",
"name":"google",
"description":"google is good"
},{
"id":"3",
"name":"micro",
"description":"micro is good"
}]
}4 在该文件夹下打开命令行：
json-server –watch db.json5 访问http://localhost:3000/users 出现相应数据即成功，同理http://localhost:3000/companies也同样有数据
