我正在设置一个支持离线浏览的渐进式网络应用程序。
我已经为我的主路由('domainsample.com/')设置了离线浏览,即使离线它也会响应 200。
但是当我导航到其他路由('domainsample.com/about')时,我收到No Internet Page
错误。
这是我在 Heroku 中部署的示例,URL:https://pwa-hehe.herokuapp.com
我使用 Vue CLI 3 设置项目,并使用 Node.js 和 Express.js 来运行服务器中的 dist 文件夹。
// server.js
const express = require('express')
const path = require('path')
const history = require('connect-history-api-fallback')
const app = express()
const staticFileMiddleware = express.static(path.join(__dirname + '/dist'))
app.use(staticFileMiddleware)
app.use(history({
disableDotRule: true,
verbose: true
}))
app.use(staticFileMiddleware)
app.get('/', function (req, res) {
res.render(path.join(__dirname + '/dist/'))
})
var server = app.listen(process.env.PORT || 3000, function () {
var port = server.address().port
console.log("App now running on port", port)
})
// manifest.json

最佳答案
有一个更简单的解决方案,不涉及使用 InjectManifest
。
只需将其添加到您的 vue.config.js
文件中即可:
pwa: {
workboxOptions: {
navigateFallback: 'index.html'
}
}
它会自动向您的 Service Worker 添加必要的代码:
workbox.routing.registerNavigationRoute(workbox.precaching.getCacheKeyForURL("index.html"));
