我在Delphi XE3上使用DCEF3。
任务是:为不同的TChromium实例创建不同的cookie存储
问题:我为每个TChromium实例创建不同的ICefCookieManager实例,并在GetCookieManager事件中返回。
示例代码:
type
TForm1 = class(TForm)
Button1: TButton;
Button2: TButton;
Chromium1: TChromium;
Chromium2: TChromium;
procedure Button1Click(Sender: TObject);
procedure Button2Click(Sender: TObject);
procedure FormCreate(Sender: TObject);
procedure Chromium1GetCookieManager(Sender: TObject;
const browser: ICefBrowser; const mainUrl: ustring;
out Result: ICefCookieManager);
procedure Chromium2GetCookieManager(Sender: TObject;
const browser: ICefBrowser; const mainUrl: ustring;
out Result: ICefCookieManager);
private
{ Private declarations }
CookieManager: ICefCookieManager;
CookieManager2: ICefCookieManager;
public
{ Public declarations }
end;
var
Form1: TForm1;
procedure TForm1.FormCreate(Sender: TObject);
begin
CookieManager:=TCefCookieManagerRef.New('C:Cookies1');
CookieManager2:=TCefCookieManagerRef.New('C:Cookies2');
end;
procedure TForm1.Chromium1GetCookieManager(Sender: TObject;
const browser: ICefBrowser; const mainUrl: ustring;
out Result: ICefCookieManager);
begin
Result:=CookieManager;
end;
procedure TForm1.Chromium2GetCookieManager(Sender: TObject;
const browser: ICefBrowser; const mainUrl: ustring;
out Result: ICefCookieManager);
begin
Result:=CookieManager2;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
Chromium1.Load('http://somesite.com');
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
Chromium2.Load('http://somesite.com');
end;
如果我将ShowMessage('First')
添加到Chromium1GetCookieManager
事件,将ShowMessage('Second')
添加到Chromium2GetCookieManager
,则无论我按下按钮1还是按钮2,都将始终显示消息"First"。
换句话说,Chromium1GetCookieManager在这两个实例中都被调用。
感谢所有人,问题得到了解决。
如何解决问题
只需关闭项目1.dpr中的cefsingprocess变量。
示例:
program Project1;
uses
Forms,
cefvcl,
ceflib,
Unit1 in 'Unit1.pas' {Form1};
{$R *.res}
begin
CefSingleProcess := False;//this what i'm talking about
Application.Initialize;
Application.CreateForm(TForm1, Form1);
Application.Run;
end.
