因为示例代码的错误，导致多数用户无法调通详情授权功能，现将正确的代码公布如下：

Dim sb As New StringBuilder
sb.AppendLine("<meta name='viewport' c>")

    Dim UserName As String
    Dim OpenID As String

        Dim ul As String  = "https://api.weixin.qq.com/sns/oauth2/access_token?appid={0}&secret={1}&code={2}&grant_type=authorization_code"
        ul = CExp(ul,"wx8acdb7df5beb68fd","dec0df8a469518df30e9bdef0758c888",e.GetValues("code"))
        Dim hc As new HttpClient(ul)
        Dim jo As JObject = JObject.Parse(hc.GetData)
        If jo("openid") IsNot Nothing Then '如果获取openid成功(成功的话,还会同时返回一个accesstiken,用于获取用户详情)
            OpenID = jo("openid")

            Else
                ul = "https://api.weixin.qq.com/sns/userinfo?access_token={0}&openid={1}&lang=zh_CN "
                '根据openid和accesstoken获取用户详情,注意这里这个accesstoken不是普通accesston,只能用于网页授权
                hc = New HttpClient(CExp(ul, jo("access_token"), OpenId))
                jo = jo.Parse(hc.GetData)
                If jo("openid") IsNot Nothing Then

                    Next
