Question

我想，这是关于django-pwa的。这个问题只出现在googlechrome中(在本地模式下，它甚至可以在127.0.0.1:8000上正常工作，但在localhost:8000上不工作(。

我的项目结构：

D:.
├───api
│   └───migrations
├───core
│   └───__pycache__
├───games
│   └───migrations
├───main
│   ├───migrations
│   └───__pycache__
├───static
│   ├───images
│   └───js
├───staticfiles
└───templates

看起来，chrome浏览器首先请求pwa.urls的空路径，但其他浏览器请求主url。我真的不知道如何让chrome从主应用程序请求我的url。

这是我的urls.py:

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
from django.views.generic import TemplateView
from rest_framework.schemas import get_schema_view
import debug_toolbar
schema_url_patterns = [
path('api/v1/', include('api.urls')),
]
urlpatterns = [
path(r'', include('main.urls')),
path('openapi', get_schema_view(
title="Gamers Gazette",
description="API!",
version="1.0.0",
patterns=schema_url_patterns,
), name='openapi-schema'),
path('swagger-ui/', TemplateView.as_view(
template_name='swagger-ui.html',
extra_context={'schema_url':'openapi-schema'}
), name='swagger-ui'),
path('redoc/', TemplateView.as_view(
template_name='redoc.html',
extra_context={'schema_url':'openapi-schema'}
), name='redoc'),
path('admin/', admin.site.urls),
path('games/', include('games.urls')),
path('api/v1/', include('api.urls')),
path("", include("pwa.urls")),
] 
if settings.DEBUG:
import debug_toolbar
urlpatterns = [
path('__debug__/', include('debug_toolbar.urls')),
] + urlpatterns

这是我的serviceworker.js:

var staticCacheName = 'djangopwa-v1';

self.addEventListener("install", event => {
this.skipWaiting();
event.waitUntil(
caches.open(staticCacheName)
.then(cache => {
return cache.addAll(filesToCache);
})
)
});
// Clear cache on activate
self.addEventListener('activate', event => {
event.waitUntil(
caches.keys().then(cacheNames => {
return Promise.all(
cacheNames
.filter(cacheName => (cacheName.startsWith("django-pwa-")))
.filter(cacheName => (cacheName !== staticCacheName))
.map(cacheName => caches.delete(cacheName))
);
})
);
});
// Serve from Cache
self.addEventListener("fetch", event => {
event.respondWith(
caches.match(event.request)
.then(response => {
return response || fetch(event.request);
})
.catch(() => {
return caches.match('offline');
})
)
});

很抱歉迭代，问题在谷歌。它缓存了一个错误版本的脚本，清理缓存后一切正常。
