What's webkitgtk version from your devices?

Edit: I believe your sample also doesn't work. Could you give more context about it? It would be best it's a wry example that I can test directly.

From my project https://github.com/fzdwx/popup-translation, and the webkitgtk version i will take you tomorrow.

[wusyong]

@fzdwx I'm really glad it's a wry project already. But I couldn't find a way to open devtool and run a fetch command. What are the steps to do it?

[fzdwx]

Sorry, my bed. Append args -p google hello

I find use with_url, fetch response body is not null ! @wusyong

[wusyong]

@fzdwx Thanks for the example again! Sorry I'm during vacation right now but I can tell you with_html on Linux doesn't really behave like http:// origin. It has many caveats which tauri doesn't really use it. It's recommended to just use custom protocol URL scheme and call with_url.

[fzdwx]

Thanks you for your reply ! But with_url only load once on window create, i want to send my request to my rust application.

If you need my help later, please call me anytime.

[wusyong]

From your use case (popup-translation), it looks like you already created the webview window and made it invisible from the start. Maybe you can create a webview window with with_url("wry://dev/google") anyway? It shouldn't be a problem, even if it's an empty webpage.

[fzdwx]

@wusyong Thanks ! But I have to think about how to change my code .

[wusyong]

Okay I think the cause is we set the origin to http://localhost. https://github.com/tauri-apps/wry/blob/dev/src/webview/webkitgtk/mod.rs#L366 We can expose an option to set it, but this will only work on macOS and Linux I'm afraid.

Has anyone managed to address this? I'm stuck here
