背景
接口域名没有写死，而是动态获取。具体实现就是 通过读取一个静态json文件，来设置真实的接口域名。好处是原域名有可能被封，这样可以直接后台操作修改该配置文件即可；不然的话，h5 项目可能还好说，app 的话必须重新发版。
代码
// httpService.js 对 uni.request 的封装。
在数据请求入口处，统一先进行 域名获取，即 执行 config.requestRemoteIp 方法
import config from '@/config'

const MockUtil = () => import('@/libs/mockUtil.js')
import Storage from '@/libs/storage.js'

async requestResolve(options, urlCustom = '', noMock = false, cacheId = null) {
let remoteIP = await config.requestRemoteIp(); // 动态设置接口请求域名
if (process.env.NODE_ENV === 'development' && config.isMockApi && !noMock) {
return this.getMockData(options)
}
if (cacheId && cacheData[cacheId]) {
return this.testHttp(cacheData[cacheId])
}
return new Promise((resolve, reject) => {
let baseUrl = process.env.NODE_ENV === 'development' ? config.baseUrl.dev : config.baseUrl.pro;
options.url = baseUrl + options.url + `${urlCustom}`;
uni.request(
Object.assign({
success: (res) => {
if (res.statusCode != '200'){
uni.showToast({
title: '服务器错误:'+res.statusCode,
icon: "none"
})
reject()
}

});
