服务人员缓存-在angular应用程序中重新加载脱机页面时出现HTTP错误504

问题描述

我无法使我的angular应用程序脱机工作。它似乎可以正确缓存，但是当我离线刷新时，它说：...花费了太长时间才能响应。 HTTP错误504

我的ngsw-config.json：

    {
  "$schema": "./node_modules/@angular/service-worker/config/schema.json","index": "/index.html","assetGroups": [
    {
      "name": "app","installMode": "prefetch","resources": {
        "files": [
          "/favicon.ico","/index.html","/manifest.webmanifest","/*.css","/*.js"
        ]
      }
    },{
      "name": "assets","installMode": "lazy","updateMode": "prefetch","resources": {
        "files": [
          "/assets/**","/*.(eot|svg|cur|jpg|png|webp|gif|otf|ttf|woff|woff2|ani)"
        ]
      }
    }
  ]
}

我还有一个.htaccess文件：

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.+)\.(\d+)\.(bmp|css|cur|gif|ico|jpg|jpe?g|js|png|svgz?|svg|webp|webmanifest|json)$ $1.$3 [L]

  # Redirection to HTTPS:
  RewriteCond %{HTTPS} !on
  RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

  # Redirection of requests to index.html
  RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]
  RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
  RewriteRule ^.*$ - [NC,L]
  RewriteRule ^(.*) index.html [NC,L]
</IfModule>

如何找出原因，我做错了什么？
