node包中routes/index.js路径配置

var express = require('express');
var router = express.Router();

router.all("*", function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "X-Requested-With");
    res.header("Access-Control-Allow-Methods", "PUT,POST,GET,DELETE,OP0TIONS");
    res.header("X-Powered-By", "Express");
    res.header("Content-Type", "text/html; charset=UTF-8");
    next();
});


router.get('/', function(req, res, next) {
    res.render('index', {
        title: 'Express'
    });
});


//自定义接口一
router.get('/apiii/list', function(req, res, next) {
    res.send({
        code: 0,
        data: {
            list: [{
                    id: 1,
                    name: 'html'
                },
                {
                    id: 2,
                    name: 'css'
                },
                {
                    id: 3,
                    name: 'javascript'
                }
            ]
        }
    })
});

//自定义接口二
router.get('/httppp/list', function(req, res, next) {
    res.send({
        code: 0,
        data: {
            name:'zhangsan',
            age:30
        }
    })
});

module.exports = router;

apiii 和 httppp 是为了和写入 “pathRewrite” 代理的api，http做区分

页面内写入

            //连接自定义端口一，代理时有pathRewrite，需要 pathRewrite + 接口名
            uni.request({
                url:'/url/apiii/list',
                method:'GET',
                success: (res) => {
                    console.log(res.data)
                }
            })
            //连接自定义端口二，代理时没有pathRewrite，直接写接口名
            uni.request({
                url:'/httppp/list',
                method:'GET',
                success: (res) => {
                    console.log(res.data)
                }
            })
