以下代码是内部函数GetOpenID的全部代码，我再网页调用该函数无法获取iopenid和name，请教一下是哪里出了问题？
Dim e As RequestEventArgs = args(0)
Dim sb As New StringBuilder
sb.AppendLine("<meta name='viewport' c>")
If e.host = Functions.Execute("Get", "公众号", "授权域名") Then '授权测试
Dim UserName As String
Dim OpenID As String
If e.GetValues.ContainsKey("code") Then '如果是通过授权链接跳转而来,就从链接重提取code来获取openid
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, Functions.Execute("Get", "公众号", "AppID"), Functions.Execute("Get", "公众号", "AppSecret"), 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")
Dim dr As DataRow = DataTables("WXUsers").Find("openid ='" & Openid & "'")
If dr IsNot Nothing Then
UserName = dr("nickname")
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
UserName = jo("nickname")
dr = DataTables("WXUsers").AddNew()
Dim nms() As String = {"openid", "nickname", "sex", "city", "country", "province", "headimgurl"} '""
For Each nm As String In nms
dr(nm) = jo(nm)
Next
dr.Save
Else
e.WriteString(jo.ToString) '在用户浏览器显示错误信息
Return Nothing
End If
End If
e.AppendCookie("username", UserName) '用户名和openid存储在Cookie中
e.AppendCookie("openid", OpenID)
Return OpenID & "|" & UserName
Else
e.WriteString(jo.ToString) '在用户浏览器显示错误信息
Return Nothing
End If
Else
UserName = e.Cookies("username") '从cookie获取用户名和openid
OpenID = e.Cookies("openid")
If userName = "" OrElse OpenID = "" Then
Dim ul As String = "https://open.weixin.qq.com/connect/oauth2/authorize?appid={0}&redirect_uri={1}&response_type=code&scope=snsapi_userinfo&state=123#wechat_redirect"
ul = CExp(ul, Functions.Execute("Get", "公众号", "AppID"), UrlEncode(Functions.Execute("Get", "公众号", "授权域名")))
sb.Append("<meta http-equiv='Refresh' c>") '跳转到授权链接
e.WriteString(sb.ToString)
Return Nothing
End If
End If
End If
