怎么给后端返回的json中添加数据

(1) 将如下代码copy之后保存为 server.js

(2) 然后执行: node server.js

var http = require('http')

var url = require('url')

// 访问的json地址与返回的json数据映射关系

var array=[

{

url:'/signup/index.json',

json:'{"tasks":[{"finishType":"人数优先","gmtEnd":"2015-11-19 11:30:00","gmtStart":"2015-11-17 11:30:00","id":98,"memo":"招新任务01","name":"招新任务01","requireNum":10,"signedupNum":0,"signupStatus":"","taskStatus":"进行中"}],"stat":"ok"}'

},

json-server用于悄判液模拟服务端接口数据，可以根据json数据建立一个完整的web服务。

github上的json-server地址

安装json-server

查看版本号，安装成功

在文件夹下创建一个db.json文件，存放一些数据。

在文件夹下，直接在地址栏cmd，进入终端。执行启动json-server命令。

json-server 已经启动成功启物。

在浏览器中输入地址： http://localhost:+ 端口号/接口名称，即可查看数据。

例如：输入 http://localhost:5000/comments

在和db.json同级的目录下，创建public目录，里面冲启可以存放一些静态资源。

在上一节里面，成功获取json-server模拟后端接口

https://www.jianshu.com/p/920d73fc32de

准备工作，先打开cmd，运行以上文章里内容：

现在要对这些接口腔册进行增删改伍唤宏查 *** 作，先写增删改查的按钮，进链烂行点击事件 的 *** 作。

打开db.json数据，发现里面添加了一条数据

删除id为2的这条数据

查询id=1的数据

参考demo
