根目录创建 package.json文件

define为环境标识，建议大写
title为环境名，出现在打包列表
UNI_PLATFORM为打包平台

创建env.uat.ts、env.prod.ts、env.dev.ts文件

const env = {
	restHost:'http://43.139.56.173:8180', // api
	gameUrl:'http://43.139.56.173:8890', // 游戏url
}
export default {
	env
}

创建env.ts文件

import Prod from './env.prod'
import Uat from './env.uat'
import Dev from './env.dev'

//api环境多的话 可以再创建文件引入

//以下是uniapp判断不同环境引入不同配置文件
/*  #ifdef  UAT-ENV */
export const environment =  Uat.env
/*  #endif  */

/*  #ifdef  PROD-ENV */
export const environment =  Prod.env
/*  #endif  */

/*  #ifndef  UAT-ENV || PROD-ENV */
export const environment =  Dev.env
/*  #endif  */

api封装文件引入env.ts文件 api封装时调用

import {environment} from '@/envList/env'
const request = (url,data,method) => {
	const token = uni.getStorageSync('token');
	let header = {
		Token: token,
		'Content-Type':'application/json; charset=utf-8'
	}
	return new Promise ((resolve,reject) => {
		uni.showLoading({
			title: "Loading..."
		});
		uni.request({
			url:environment.restHost+url,
			data:data,
			header:header,
			method:method,
			timeout: 30000,
			success(res) {
				uni.hideLoading();
				// token refresh
				if(res.header['new-token']) {
					uni.setStorageSync('token',res.header['new-token'])
				}
				if (res.data.code == 200) {
					resolve(res.data)
				}else{
					reject(res.data);
					uni.showToast({
						title: res.data.error.msg,
						icon:"error",
						duration:2000
					});
				}
			},
			fail(err) {
				reject(err);
				uni.showToast({
					title: 'error',
					icon:"error",
					duration:2000
				});
			},
			complete() {
				uni.hideLoading();
			}
		})
	})
}
