测试

编写API接口文档

1.Account模块Restful

1.1.添加

/account/add

提交
 {
       "id":"104",
        "name": "jack2",
        "value": 900
}

返回
{
    "code": 200,
    "msg": "添加成功",
    "data": null
}

1.2.修改
/account/update

提交
 {
       "id":"104",
        "name": "tony",
        "value": 9000
}
{
    "code": 200,
    "msg": "修改成功",
    "data": null
}

1.3.删除
/account/delete/101

提交
无
{
    "code": 200,
    "msg": "删除成功",
    "data": null
}

1.4.查一个
/account/find/101

提交
无
{
    "code": 200,
    "msg": "查询成功",
    "data": {
        "id": "101",
        "name": "jack",
        "value": 100
    }
}

1.5.查所有
/account/find

提交
无
{
    "code": 200,
    "msg": "查询成功",
    "data": [
        {
            "id": "101",
            "name": "jack",
            "value": 100
        },
        {
            "id": "102",
            "name": "rose",
            "value": 100
        },
        {
            "id": "103",
            "name": "tony",
            "value": 100
        }
    ]
}
