I want to use tauri to create a desktop program, that support display local html file.
I had try to use iframe,set iframe src like $HOME/.tarui_app/third.html,it can't load..

hmm, maybe try setting the asset protocol as the iframe source via https://tauri.app/v1/api/js/tauri/#convertfilesrc

thks bro
there's some trouble.

1. when I use iframe, app will warn[TAURI] Couldn't find callback id 3551468386 in window. This happens when the app is reloaded while Rust is running an asynchronous operation.
2. iframe doesn't support assets protocol,error message Failed to load resource: unsupported URL

btw, It will autocreate appDataDir when I start App?

@FabianLars I tried convertFileSrc, it could load the html, but not the .js and .css files.

convertFileSrc return absolute path like asset://localhost//<paths>/index.html. In the index.html dependencies are loaded with relative path

<script type="module" crossorigin src="./assets/index-CZGpdclX.js"></script>
<link rel="stylesheet" crossorigin href="./assets/index-BHYCjRZw.css">

But the webview tries to load asset://localhost/assets/index-BHYCjRZw.css and asset://localhost/assets/index-CZGpdclX.js

The <path> section is omited. Do you know any way to work around this?

Since the absolute path on each computer is different, I can't simply change the base URL for the loaded web page.

It's possible with tauri-apps/wry: tauri-apps/wry#761 (comment). (It's the underlying cross-platform WebView library.)
