SPA PWA在子文件夹上未显示横幅

Question

我想在非根域（https://ireading.site/test/）上服务单页应用程序（Vue）PWA网站。它工作正常，但未显示安装横幅。

我的nginx conf是

 location /test {
        root   /var/www/;
        index  index.html index.htm;
        add_header Service-Worker-Allowed /;
        try_files $uri $uri/ /test;
    }

我的manifest.json是

"start_url": "/test",
"name": "pwa-project",
"short_name": "pwa-project",
"icons": [
    {
        "src": "img/icons/android-chrome-192x192.png",
        "type": "image/png",
        "sizes": "192x192"
    }
],
"display": "standalone"

文件结构为

/var/www/test
├── favicon.ico
├── index.html
├── lavas
│   └── routes.json
├── precache-manifest.4090d927e22f86d75520df465789c2ba.js
├── service-worker.js
├── static
│   ├── css
│   ├── img
│   ├── js
│   ├── manifest.json
│   └── workbox-v3.6.3
└── sw-register.js

如果我将其手动添加到我的android设备的桌面上，但未提示安装横幅，效果很好。

在Chrome审核User will not be prompted to Install the Web App Failures: Service worker does not successfully serve the manifest's start_url, Timed out waiting for fetched start_url.

中

是否可以将其托管在子文件夹上并正确显示安装横幅？
