delphi - 如何设置 cookie HTTPOnly 标志？

Question

如何设置HTTPOnly旗帜？TCookie 没有任何方法或属性来指定 HTTPOnly 标志。

Answer 1

如果您在 HttpApp.pas 中谈论 TCookie，则没有内置属性来支持 HttpOnly。

您可以查看 httpApp.pas 中的 TCookie.GetHeaderValue: string; 实现来进行验证。

然而，Cookie 只是 header 中设置的内容，而 TWebResponse 有一个 CustomHeaders属性(property)。您可以在哪里调用 Response.CustomHeaders.Add(MyCookieValue);

以下类是 TCookie 的修改版本，用于支持 HttpOnly，您可以使用它来正确生成 cookie。

unit CookieGen;

interface
uses
 Sysutils,Classes,HttpApp;
type
  TCookieGenerator = class(TObject)
  private
    FName: string;
    FValue: string;
    FPath: string;
    FDomain: string;
    FExpires: TDateTime;
    FSecure: Boolean;
    FHttpOnly: Boolean;
  protected
    function GetHeaderValue: string;
  public
    property Name: string read FName write FName;
    property Value: string read FValue write FValue;
    property Domain: string read FDomain write FDomain;
    property Path: string read FPath write FPath;
    property Expires: TDateTime read FExpires write FExpires;
    property Secure: Boolean read FSecure write FSecure;
    property HttpOnly : Boolean read FHttpOnly write FHttpOnly;
    property HeaderValue: string read GetHeaderValue;
  end;

implementation

{ TCookieGenerator }

function TCookieGenerator.GetHeaderValue: string;
begin
  Result := Format('%s=%s; ', [HTTPEncode(FName), HTTPEncode(FValue)]);
  if Domain <> '' then
    Result := Result + Format('domain=%s; ', [Domain]);  { do not localize }
  if Path <> '' then
    Result := Result + Format('path=%s; ', [Path]);      { do not localize }
  if Expires > -1 then
    Result := Result +
      Format(FormatDateTime('"expires="' + sDateFormat + ' "GMT; "', Expires),  { do not localize }
        [DayOfWeekStr(Expires), MonthStr(Expires)]);
  if Secure then Result := Result + 'secure; ';  { do not localize }
  if HttpOnly then Result := Result + 'HttpOnly';  { do not localize }
  if Copy(Result, Length(Result) - 1, MaxInt) = '; ' then
    SetLength(Result, Length(Result) - 2);

end;

end.
