TWebView() and Google Group Account

[Antonio Linares]

Teoretically we can do it using javascrit, it is explained here:
https://stackoverflow.com/questions/23248525/setting-a-custom-useragent-in-html-or-javascript

trying it...

[Antonio Linares]

I am trying this with no success yet:

oWebView:Eval( "navigator.__defineGetter__('userAgent', function () { return 'Chrome' } );" )

In fact, from the inspector console you can try this javacript:

console.log( navigator.userAgent );
navigator.__defineGetter__('userAgent', function () { return 'Chrome' } );
console.log( navigator.userAgent ); // we get Chrome here

I think we are quite close to get it...

New answer from Steffen and our answer to him. Meanwhile we don't find a way to programmatically uncheck the default userAgent from the inspector, I guess that there is no other way except doing it by "hand"

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

this code should do the "magic" and in fact it changes the navigator.userAgent but still forces us to manually uncheck the default userAgent from the inspector:

Code: Select all  Expand view

function Main()

   local oWebView := TWebView():New()

   oWebView:bOnBind = { | cJson, nCalls | MsgInfo( cJson, nCalls ) }
   oWebView:Bind( "SendToFWH" )
   oWebView:Navigate( "http://www.google.com" ) // Html() )
   Sleep( 200 )
   oWebView:Eval( "navigator.__defineGetter__('userAgent', function () { return 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.5060.53 Mobile Safari/537.36' } )" )
   oWebView:Eval( "SendToFWH( navigator.userAgent )" )
   oWebView:Run()
   oWebView:Destroy()

return nil

Miracle exists... Steffen has included a new function into webview.dll thanks to our requests:

Code: Select all  Expand view

https://github.com/webview/webview/issues/792#issuecomment-1172852232

While your approach may work, I suspect that it is not going to be sufficient because the user agent is sent to the server with every HTTP request, and I doubt that you can successfully intercept them all using only JavaScript. The sure way to make this work is to integrate it properly with the underlying browser engine (e.g. WebView2 as you are using Windows).

Here it is the commit he did this morning:
https://github.com/webview/webview/compare/master...SteffenL:webview:up/set-user-agent

where he is adding a new function:

Code: Select all  Expand view

WEBVIEW_API void webview_set_user_agent(webview_t w, const char *agent);

Now we just need to rebuild the DLL and test it...
It feels simply great when you find people like Steffen...

[Antonio Linares]

c:\>git clone --branch up/set-user-agent https://github.com/SteffenL/webview webview_useragent

Then open a "Developer command prompt for VS2022" as administrator and go to c:\webview_useragent\script\

and run build.bat

We got webview.dll properly built and it is working fine and the problem is solved !!!!!!!!!!!!!!!!

Here it is the FWH code to access google.com and identify yourself with no issues at all

Code: Select all  Expand view

#include "FiveWin.ch"

//----------------------------------------------------------------------------//

function Main()

   local oWebView := TWebView():New()

   oWebView:Navigate( "http://www.google.com" )
   Sleep( 200 )
   oWebView:SetUserAgent( "Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.5060.53 Mobile Safari/537.36" )
   oWebView:Run()
   oWebView:Destroy()

return nil

Working as expected !!! Great!
