Sending POST data to Webview2

[lopezvg]

Any plan to support sending PostData to Webview2. Needed for sending login/password, etc

I'm not sure I understand the question, or what it is you're trying to do. Toga's WebView is a mechanism for displaying web content; and the way you interact with web content is to invoke Javascript. Toga has the ability to invoke user-supplied JavaScript - does that not provide what you need?

Based on some specific "on_webview_load" responses from the web id need to send a "Http POST Request" with some parameters in PostData and some Headers, to filter the desired result.

I understand the mechanism and I've used successfully a JavaScript to post parameters. But in many cases webs does not let injecting a JavaScript to post parameters, probably for security reasons. Probably there are ways to go around these security blocks but my JavaScript is very basic.

I've been reading about Webview2 API and I've found the method "CoreWebView2Environment.CreateWebResourceRequest", that with "CoreWebView2.NavigateWithWebResourceRequest" would do the job without involving user-supplied JavaScript

Ok - so that's an issue with what you're trying to do, and the web browser security model. The server may require CORS or similar handling to be enabled. Without any details, it's impossible to say any more about that - but assuming it is CORS (or similar), there's very little that Toga is going to be able to do to fix this.

Sure, that API exists... but it's a "Web Resource Request". Unless you've got evidence to the contrary, I'd be shocked to find that those APIs wouldn't be subject to the same security restrictions as an in-browser Javascript request. It's entirely likely that the Javascript implementation uses that exact API to implement the request.
