在uniapp的项目里面，怎么写入模拟接口数据？现在使用node服务实现几个模拟接口，当然是用mock也是可以的哦，方法有很多种，目的只有一个，就是能够娴熟的应用在项目场景里面。

1：json数据写在data底下的js里面

json.js

let data = {
     //这里放数据
     "categories": [
         "1",
         "2",
         "3",
         "4",
         "5",
         "6",
         "7",
         "8",
         "9",
         "10",
         "11",
         "12"
     ],
     "data": [
         3,
         2,
         4,
         4,
         5
     ]
}
module.exports = {
  data: data
}

json1.js

let data = {
    "echatX": [
        "2019-07-02",
        "2019-07-03",
        "2019-07-04",
        "2019-07-05",
        "2019-07-06",
        "2019-07-07",
        "2019-07-08",
        "2019-07-09",
        "2019-07-10",
        "2019-07-11",
        "2019-07-12",
        "2019-07-13",
        "2019-07-14",
        "2019-07-15"
    ],
    "echatY": [
        120,121,123,123,125,127,128,129,120,123,122,126,129,122
    ],
    "echatY2": [
        60,64,63,63,65,67,68,69,61,66,65,68,69,65
    ],
    "echatY3": [
        60,64,63,63,65,67,68,69,161,66,65,68,169,165
    ]
}

module.exports = {
  data: data
}

json3.js

let data = {
    "first":[
        {"name":"王小婷","nick":"祈澈菇凉"},

        {"name":"安安","nick":"坏兔子"},

        {"name":"编程微刊","nick":"简书"}      
    ]
}
module.exports = {
  data: data
}

以上是自己随意造的数据啊不要过于在意了

2：在项目底下新建一个server文件夹，用来写我的node服务。

server.js

const http = require("http");
const data = require("../data/json");
const data2 = require("../data/json1");
const data3 = require("../data/json3");

const server = http.createServer((req, res) => {
    //解决跨域问题
    res.setHeader('Access-Control-Allow-Origin', '*');
    res.setHeader('Access-Control-Allow-Headers', 'Content-Type, Content-Length, Authorization, Accept, X-Requested-With , yourHeaderFeild');
    res.setHeader('Access-Control-Allow-Methods', 'PUT, POST, GET, DELETE, OPTIONS');
    res.writeHead(200, {
    'Content-Type': 'application/json'
    });
    if(req.url === '/'){
        res.end(JSON.stringify(data.data))
    }
    if(req.url === '/data'){
        res.end(JSON.stringify(data2.data))
    }
    
    if(req.url === '/data3'){
        res.end(JSON.stringify(data3.data))
    }
});

server.listen(3000, () => {
    console.log("server is running!")
})

3：运行在编辑器的内置终端里面，进入文件夹server，启动刚刚写的服务

cd  server

$ node --inspect  server.js

4：打开浏览器，就可以看到模拟接口实现啦 http://localhost:3000/

http://localhost:3000/data

http://localhost:3000/data3

5:测试一下，就用这个接口吧http://localhost:3000/data3

<template>
    <view>     
        <view class="uni-padding-wrap uni-common-mt" v-for="item in itemList">
             <span>{{item.name}}</span>
             <span>{{item.nick}}</span>
        </view>
    </view>
</template>
<script>
    export default {
        data() {
            return {  
                 itemList: []
            }
        },
        onLoad() {
                   this.getList();
               },
        methods: {
             getList() {
                uni.request({
                    url: 'http://localhost:3000/data3', 
                    success: (res) => {
                        console.log(res.data);
                         this.itemList =res.data.first;
                    }
                });
            }
        }
    }
</script>
<style>
.img {
    width: 500upx;
    height: 500upx;
    margin: 0 95upx;
}
</style>

好的，测试成功了，数据也可以显示啦
