如何将manifest.json的start_url设置为站点的根目录？

Question

我有一个manifest.json,它有一个start_url属性,我想指向我的单页面应用程序的第一个文件.

这是index.html,它是网站的根源.我希望这是start_url,但该文件永远不会被要求作为URL.

我如何指向start_url网站的相对根？

例如,假设该网站是在https://example.com什么应的值start_url是https://example.com/manifest.json？我希望PWA从而开始https://example.com而不是 https://example.com/index.html.PWA可能放在不同的域上,因此start_url需要是相对的,而不是绝对的.

Answer 1

您的清单文件中的start_url应该设置为以下内容。

"start_url": "/"

Answer 2

If you are running in the root of a site, for instance https://example.com/manifest.json or https://test.example.com/manifest.json you can use "start_url": "/".

However, this will also map https://example.com/test/manifest.json to https://example.com/, which fails because it's in a folder outside the scope of the manifest.

Instead, if you are using a sub-directory you need to set both a scope and the start_url:

"start_url": "./"
"scope": "."

This will cause https://example.com/test/manifest.json to map to https://example.com/test/ as expected.
