以下配置会引发“不支持请求方法 'POST'”的错误。我已经读到存储 api 不使用 POST 方法请求对象作为缓存中的键，但我不知道如何添加路由，该路由显示了这些请求的 networkOnly 策略。
规格（设置取自https://github.com/nystudio107/annotated-webpack-4-config）
- 使用 GenerateSW
webpack.settings.js（记住 importScripts 语句）
workboxConfig: {
swDest: "../sw.js",
precacheManifestFilename: "js/precache-manifest.[manifestHash].js",
importScripts: [
"/dist/workbox-catch-handler.js"
],
exclude: [
/\.(png|jpe?g|gif|svg|webp)$/i,
/\.map$/,
/^manifest.*\\.js(?:on)?$/,
],
globDirectory: "./web/",
globPatterns: [
"offline.html",
"offline.svg"
],
offlineGoogleAnalytics: true,
runtimeCaching: [
{
urlPattern: /\.(?:png|jpg|jpeg|svg|webp)$/,
handler: "cacheFirst",
options: {
cacheName: "images",
expiration: {
maxEntries: 20
}
}
}
]
}
wepack.prod.js
// webpack.prod.js - production builds
const LEGACY_CONFIG = 'legacy';
const MODERN_CONFIG = 'modern';
const WorkboxPlugin = require('workbox-webpack-plugin');
// config files
const settings = require('./webpack.settings.js');
const common = require('./webpack.common.js');
...
// Configure Workbox service worker
const configureWorkbox = () => {
let config = settings.workboxConfig;
return config;
};
// Module Exports – simplified for clarity - see github repro for more details
module.exports = [
...
...,
merge(
common.modernConfig,
{
...
...
plugins: [
...
new WorkboxPlugin.GenerateSW(
configureWorkbox()
),
]
}
]
工作箱-catch-handler.js
// fallback URLs
const FALLBACK_HTML_URL = '/offline.html';
const FALLBACK_IMAGE_URL = '/offline.svg';
// This "catch" handler is triggered when any of the other routes fail to
// generate a response.
workbox.routing.setCatchHandler(({event, request, url}) => {
// Use event, request, and url to figure out how to respond.
// One approach would be to use request.destination, see
// https://medium.com/dev-channel/service-worker-caching-strategies-based-on-request-types-57411dd7652c
switch (request.destination) {
case 'document':
return caches.match(FALLBACK_HTML_URL);
break;
case 'image':
return caches.match(FALLBACK_IMAGE_URL);
break;
default:
// If we don't have a fallback, just return an error response.
return Response.error();
}
});
// Use a stale-while-revalidate strategy for all other requests.
workbox.routing.setDefaultHandler(
workbox.strategies.staleWhileRevalidate()
);
该错误是由 DefaultHandler 的策略引起的，因此我尝试在 DefaultHandler 正下方为这些请求添加另一条路由，但没有成功。例如：
workbox.routing.registerRoute(
new RegExp('*/admin/*'),
workbox.strategies.networkOnly()
);
我也尝试了 bgSyncPlugin，但没有成功。任何帮助表示赞赏。我想为 POST 请求（不仅仅是管理 URL）实施一个侧宽 networkOnly 策略。
