If e.host = "wexin.foxtable.com" Then '需要授权才能访问的域名
    Dim UserId As String
    Dim UserName As String
    Dim sb As New StringBuilder
    sb.AppendLine("<meta name='viewport' c>")
    If e.GetValues.ContainsKey("code") Then '如果通过授权链接跳转而来,就根据传递过来的code参数调用接口,获取用户的UserId
        Dim ul As String = "https://qyapi.weixin.qq.com/cgi-bin/user/getuserinfo?access_token={0}&code={1}"
        ul = CExp(ul,Functions.Execute("GetQYAccessToken"),e.GetValues("code"))
        Dim hc As new HttpClient(ul)
        Dim jo As JObject = JObject.Parse(hc.GetData)
        If jo("UserId") IsNot Nothing Then
            UserId = jo("UserId")
        End If
    Else
        UserId = e.Cookies("userid") '否则从cookie中提取userid和username
