Accept-Language

[Vaytl]

Hi, salvadordf. Please tell me how to set my "Accept-Language" in the header?
Is there a way to set my header somehow?

The default language setting is ‘zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6’；
Although it's strange why you need to modify it, I tried and found the location of the modification.
It's strange that modifications did not work in event ‘NavigationStarting’.
After modification in the event ‘WebResourceRequested’,It is effective。

procedure TBrowserFrame.WVBrowser1WebResourceRequested(Sender: TObject;
const aWebView: ICoreWebView2;
const aArgs: ICoreWebView2WebResourceRequestedEventArgs);
var
TempArgs : TCoreWebView2WebResourceRequestedEventArgs;
RequestHeaders:ICoreWebView2HttpRequestHeaders;
begin
TempArgs:= TCoreWebView2WebResourceRequestedEventArgs.Create(aArgs);
try
TempArgs.Request.Get_Headers(RequestHeaders);
RequestHeaders.SetHeader('Accept-Language','zh-cn;q=0.8,en-US;q=0.9');

finally
TempArgs.Free ;
end;
end;
