1.1.node搭建本地服务器

1.创建一个服务器文件夹

在本地创建文件夹，用于存储服务器相关文件

2.把两个配置文件拷贝过去

代码太长放在文章末尾了

3.根据刚刚拷贝的package配置安装依赖

在服务器文件夹qmcn_s下运行命令行：
cnpm i

4.创建服务器js文件

现在的目录结构

5.编写js文件

const express = require('express');
const app = express();
const fd = require('formidable');
const fs = require("fs");
const bp = require('body-parser');
app.use(bp.urlencoded({extended: false
}));
const cors = require('cors');
app.use(cors());
app.all('*', function(mes, res, next) {res.setHeader('Access-Control-Allow-Origin','http://localhost:63342')next();
})
app.use(express.static('./'));app.listen(7890, function() {console.log('服务器开启监听，7890...')
})

以上内容粘贴过去就行了，简易服务器完成

6.运行服务器

7.写一个接口测试一下

小程序客户端：

服务端s.j：

效果如下:
服务端接收：

客户端响应：
