基于jwt制作Token

function TfrmSimple.BuildTokenFR(path, key: string; validtime:Int64): string;
var
   LToken: TJWT;
begin
     LToken := TJWT.Create;
     try
        LToken.Claims.Subject := path;
        LToken.Claims.IssuedAt := Now;
        LToken.Claims.Expiration := Now + validtime;
        LToken.Claims.Issuer := '';
        LToken.Claims.JWTId:='';
        result:=TJOSE.SHA256CompactToken(key,LToken);
     finally
        LToken.Free;
     end;
end;

直接上代码，下面是调用代码：

 memoCompact.Lines.Add(  BuildTokenFR('order.cpt','123456',30*60*1000));

返回结果：
