How to use the "post_asset_folder" URL when specifying a cover in front matter?

[Kritner]

I'm making use of a post_asset_folder, where all my post's images and the like are stored in a folder in source as YYYYMMDD-my-post-title. If I have a cover image, it is in the directory /source/_posts/20210101-my-post-title/cover.png as an example. This post then gets generated under /public/2021/01/01/my-post-title/cover.png and is hit through the URL /2021/01/01/my-post-title/cover.png.

When using a thumbnail in the front matter, the post_asset_folder is taken into account in such a way that the image source is the full URL to the image, including its subfolders, such as https://example.com/2021/01/01/my-post-title/cover.png. However, when using the cover in the front matter, only https://example.com/cover.png is being returned as the "image url". This is causing broken image links on the "cover" but not the "thumbnail", is there a way to get the cover to correctly use the post_asset_folder URL construction as well?

@Kritner Could you please try the following changes?

At https://github.com/ppoffice/hexo-theme-icarus/blob/4.4.0/layout/common/article.jsx#L36

- <img class="fill" src={cover} alt={page.title || cover} />
+ <img class="fill" src={url_for(cover)} alt={page.title || cover} />

At https://github.com/ppoffice/hexo-theme-icarus/blob/4.4.0/layout/common/article.jsx#L38

- <img class="fill" src={cover} alt={page.title || cover} />
+ <img class="fill" src={url_for(cover)} alt={page.title || cover} />

Thanks @ppoffice I gave it a shot, but it didn't seem to work:

(Note I did attempt by swapping the line 36/38 like requested, when that didn't work I just logged the output set above to see what I was working with)

I ended up removing the hexo-featured-image package, which once doing so has broken the link for thumbnail as well:

I mention the above before when I was using the hexo-featured-image package, thumbnail was working, but not cover (though featured image expects featured_image as the front matter trigger word). After removing hexo-featured-image both thumbnail and cover are just going to the URL (in the case of running in localhost) http://localhost:4000/cover.png rather than my expected http://localhost:4000/2021/01/01/my-post-title/cover.png.

The reproduction of this can be found here: https://github.com/Kritner/HexoFeaturedImageRepro/tree/hexoUpgrade. Hopefully I've just missed something in my settings, but I have the post_asset_folder: true, which I would have expected the url_for to account for. It looks like there was a pretty recent change to url_for in hexojs/hexo-util#262, but I haven't compared the icarus theme's hexo-util version to the version that the mentioned PR would have been released with (assuming it's even been released to NPM at this point).

Ok. In that case the asset folder feature is simply not supported. Previously, the link worked for thumbnail because you had hexo-featured-image installed.
