How to dynamically set default header for all the request for tauri app

[crackleeeessyp]

Seems currently we can setup default header in tauri.config.json file, but how can I set it dynamically in rust?

1. those headers are only set on requests to the tauri built-in protocols. if you're asking for general requests to a non-tauri url then this doesn't help
2. only support in tauri.conf.json, see https://github.com/tauri-apps/tauri/pull/11485/files. That said, you can modify the config in rust before the tauri::Builder line similar to https://github.com/tauri-apps/tauri-plugin-localhost#usage

you can modify the config in rust

OK, thanks! It is useful to change config in runtime.

I'm looking for a way to set headers for all network requests. I hope a future version will include this feature. In Electron, I can use Session to achieve this.

This won't be possible as long as we use the system webviews. They simply do not allow this (except Windows).

Not sure how electron can intercept request, and I think android platform can also intercept request

[FabianLars]

Electron uses their own fork of chromium so they have full control over the webengine. We rely on the one included in the OS and have to live with what they allow us to do.

and I think android platform can also intercept request

could be yeah, but then we're at 2 out of 5 platforms :/

@crackleeeessyp You sure asked for response and not request headers? The latter is supported by wry as https://docs.rs/wry/0.54.1/wry/struct.WebView.html#method.load_url_with_headers. It's not exposed by tauri.
