hi Antonio,

thx for Answer.

i have found similar at Github and have read about Google oAuth
i saw Comment to add

Code: Select all | Expand

disallow_webview=true

after URL but how to do it with CLASS TWebView

Code: Select all | Expand

METHOD Navigate( cURL ) INLINE WebView_Navigate( ::hWebView, cURL )

p.s. when modify FiveWin Source how to rebuild LIB (BCC 7 fiveh.lib, fivehc.lib )

[Antonio Linares]

Dear Jimmy,

Have you tried to run this, after you go to https://accounts.google.com/o/oauth2/v2/auth ?

oWebView:Eval( "disallow_webview=true;" )

Anyhow, I have just set an issue in the github webview repo asking for it and lets see what they say:

Dear Jimmy,

> p.s. when modify FiveWin Source how to rebuild LIB (BCC 7 fiveh.lib, fivehc.lib )

Once you modify the source and compile generating the OBJ simply do this:

c:\bcc7\bin\TLib Fiveh.lib -+$module.obj /0 /P128

same applies for fivehc.lib

Dear Jimmy,

Steffen from webview answered this:

Sorry, I am having a hard time seeing how this is related to this webview library. If you could please explain then that would be helpful. Thank you!

Good question. What to tell him ?

[Jimmy]

hi Antonio,

Sample Webview start with Google Website

Code: Select all | Expand

   local oWebView := TWebView():New()
oWebView:Eval( "disallow_webview=true;" )
   oWebView:Navigate( "http://www.google.com" )
oWebView:Eval( "disallow_webview=true;" )

i upper right of Google Website i try login with UserName and than still got Error Message.

as i understand Google Website can not "identify" which Browser is used

Dear Jimmy,

> Question : can i use TWebview() in "IE compatible" Modus

I have no idea about this, sorry

Dear Jimmy,

New answer from Steffen and then he closed the issue:

Thank you.

From my understanding, disallow_webview=true was at the time just way for developers to test whether their apps would be impacted by Google blocking embedded webviews in their OAuth 2.0 authorization flows before making the block effective for everyone.

You can add a query parameter to your authorization request URI to test for potential impact to your application before September 30, 2021

If the question is about how to add that query parameter anyway then I think you need to dive into Google's documentation and get a better understanding of their OAuth 2.0 authorization flow. I do however not think that this applies anymore.

To me it seems like this is on Google for dictating what type of browser is permitted in their authorization flow, and I think that every solution is going to be a workaround.

Should you find that there is a specific technical limitation in this webview library or how it integrates with the underlying browser engines (not only MS WebView2) then I suggest making a new, more specific issue with those details.

I will close this issue as I do not see any way to move forward

If you could explain, step by step, how to reproduce it here maybe we can think about a solution. Please post an animated gif or several screenshots.

many thanks

hi Antonio,

i try to login at Google Website with upper right Button ( use Fullscreen of Browser if you don´t see it )


i need Google Account e.g. for "harbour Group" in Google.

---

i have the "feeling" that Google can not "identify Browser", that´s why i ask for "IE-Compatible" Modus

[Antonio Linares]

Dear Jimmy,

It seems as there is an "easy" solution:
https://github.com/MicrosoftEdge/WebView2Feedback/issues/1647

You are all geniuses，Settings.UserAgent = "Chrome" Settings.UserAgent = "Android" ，It's working

Now we need to follow this guide to change the UserAgent:
https://www.searchenginejournal.com/change-user-agent/368448/

I am trying it right now...

[Antonio Linares]

Got it !!!

I am posting the screenshots...

[Antonio Linares]

I just explained this to Steffen asking him for a way to do it programmatically:

https://github.com/webview/webview/issues/792

Lets see what he says...
