uniapp 微信小程序封装公共的请求js（api版本）

一、新建api文件夹
在项目目录下创建api文件夹，内放files跟index.js文件夹，files文件夹内放每个页面对应的js请求接口
在这里插入图片描述
1、index.js

/*** api接口的统一出口*/
const api = {};
const requireComponent = require.context('./files', false, /\.js$/)
requireComponent.keys().forEach(fileName => {const componentName = fileName.replace(/^\.\/(.*)\.\w+$/, '$1')const componentConfig = requireComponent(fileName)api[componentName] = componentConfig.default
})
export default api;

2、例如：login.js

/*** 登录用到的接口*/
import http from '@/utils/http.js'
import config from '@/utils/config.js'
const login = {//角色001-账号登录transportLogin(data){return new Promise((resolve, reject) => {http.request({domain:config.adminDomain,//接口ip地址+端口号（第一种）url: "/user/login",method: "POST",data,callBack: res => {resolve(res);}})})},//角色002-账号登录regulatorLogin(data){return new Promise((resolve, reject) => {http.request({domain:config.domain,//接口ip地址+端口号（第二种）url: "/wx/login",method: "POST",data,callBack: res => {resolve(res);}})})}
}
export default login;

二、config.js

const domain = "http://192.888.888.6:80/my"
const adminDomain = "http://192.888.444.9:800"
const adminH5 = "http://192.888.666.7:82/#";
module.exports = {domain,adminDomain,adminH5
}

三、main.js
在这里插入图片描述

四、页面使用

<template><view class="login-btn" @click="toLogin">登录</view><view class="login-btn" @click="toLogin2">登录</view>
</template>

methods: {toLogin(){this.$api.login.transportLogin(data).then(res=>{uni.hideLoading()if (res.code === 200) {// 保存登陆信息uni.setStorageSync('loginResult', res)uni.setStorageSync('token', res.token);uni.setStorageSync('login',false);uni.reLaunch({url: "/pages/learning/learning"})}})},toLogin2(){let data = {account: "", //用户名pwd: "" //密码};this.$api.login.regulatorLogin(data).then(res=>{uni.hideLoading()if (res.code === 200) {// 保存登陆信息uni.setStorageSync('loginResult', res)uni.setStorageSync('token', res.token);uni.setStorageSync('login',false);uni.reLaunch({url: "/pages/learning/learning"})}})}
}
