编写涉及：css, html,js, node(koa)
html代码

hash方式
class HashRoute {
setRoute() {
const commandObj = {
one: 'page one',
two: 'page two',
three: 'page three'
}
const hashRoute = location.hash ? location.hash.slice(2) : 'one'
let re = commandObj[hashRoute]
document.getElementById('hashContent').innerHTML = re ? re : 'page not find'
}
skip(path) {
window.location.hash= `#/${path}`
}
init() {
window.addEventListener('DOMContentLoaded', this.setRoute)
// 1.直接更改浏览器地址，在最后面增加或改变#hash；
// 2.通过改变location.href 或 location.hash的值；
// 3.通过触发点击带锚点的链接；
// 4.浏览器前进后退可能导致hash的变化，前提是两个网页地址中的hash值不同
window.addEventListener('hashchange', this.setRoute)
}
}
const hashRoute = new HashRoute()
hashRoute.init()history 方式
浏览器端代码
// 服务端有效
class HistoryRoute {
constructor() {
this.currentPath = ''
}
renderView(component) {
const route = {
pushStateOne: 'route pushState one',
pushStateTwo: 'route pushState two',
pushStateThree: 'route pushState three',
replaceState: 'route replaceState',
go: 'route go',
forward: 'route forward',
back: 'route back',
notFind: 'not find',
}
document.getElementById('historyContent').innerHTML = route[component]
}
// 这里所有涉及的跳转都用js方式，不采用a标签(采用a标签请设置拦截)
skip(path) {
const commandObj = {
pushStateOne: () => {
history.pushState({ path }, path,path)
this.renderView(path)
},
pushStateTwo: () => {
history.pushState({ path }, path, path)
this.renderView(path)
},
pushStateThree: () => {
history.pushState({ path }, path, path)
this.renderView(path)
},
replaceState: () => {
// 是用来修改当前的history实体而不是创建一个新的,比如连转顺序为1，2，3，1执行replaceState(2),再执行back()，返回1，而不是3
history.replaceState({ path }, path, path)
this.renderView(path)
},
go: () => {
history.go(2)
this.renderView('go')
},
forward: () => {
history.forward()
this.renderView('forward')
},
back: () => {
history.back()
},
}
this.currentPath = path;
commandObj[path]()
}
init() {
window.addEventListener('DOMContentLoaded', () => {
// 针对F5刷新问题:
// 1.可以使用？后面跟参数形式
// 2.统一入口利用忽略地址方式（后端配置 /page/:path 忽略page后跟的所有地址，通过前端去请求page后的对应路由数据，如下）
const path = location.href.split('/page/')
this.skip(path[1])
})
// 调用history.pushState()或history.replaceState()不会触发popstate。
// 只有在用户点击前进回退按钮，(或history.back()，forward，go)
window.addEventListener('popstate', (event) => {
console.log('popstate', this.currentPath, event.state);
const { state } = event
if (state && state.path) {
this.renderView(state.path)
} else {
this.renderView('404')
}
})
}
}
const historyRoute = new HistoryRoute()
historyRoute.init();服务器端
// 结合前端，可以用以下方式处理
router.get('/page/:path', (ctx, next) => {
ctx.response.type = 'html';
// 此处的singlePageRoute.html为单页面html容器，即放置本文中的所有代码文件
ctx.response.body = fs.createReadStream('./dist/public/files/singlePageRoute.html');
return next();
