3、Foxtable的HttpRequest事件代码设置为:
If e.host = "wexin.foxtable.com"
Then
'需要授权才能访问的域名
Dim
OpenID
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,"wx8acdb7df5beb68fd","a5a3b06a790d4200a151e6b13c3dc263",e.GetValues("code"))
Dim hc As new HttpClient(ul)
Dim
jo As JObject = JObject.Parse(hc.GetData)
If jo("openid") IsNot
Nothing
Then
OpenID = jo("openid")
e.AppendCookie("openid",OpenID)
'将openid存储在Cookie中
End
If
Else
OpenId = e.Cookies("openid")
'否则从cookie中提取openid
End
If
Dim Verified As
Boolean
Dim dr As
DataRow =
DataTables("WXUsers").Find("openid ='"
& OpenID &
"'") '根据openid找出对应的行
If
OpenId >
"" AndAlso
dr IsNot
Nothing
AndAlso dr("permit") = True
'授权成功
Verified = True
ElseIf
e.GetValues.ContainsKey("code") = False
Then
'如果授权失败,且不是通过授权链接跳转而来,那么就跳转到授权链接
Dim ul As
String = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx8acdb7df5beb68fd&redirect_uri=http%3a%2f%2fwexin.foxtable.com&response_type=code&scope=snsapi_base&state=123#wechat_redirect"
sb.Append("<meta
http-equiv='Refresh' c>")
'跳转到授权链接
e.WriteString(sb.ToString)
Return
End
If
If
Verified = False
Then
sb.AppendLine("你无权访问本系统")
Else
sb.AppendLine("Foxtable欢迎您,
<a href='http://wexin.foxtable.com'>刷新页面</a>")
End
If
e.WriteString(sb.ToString)
End
If
按照帮助里面,只有经过授权的微信账户,才能通过访问"http://wexin.foxtable.com",但是在使用过程中还需要访问其他的页面,比如http://wexin.foxtable.com/2313.html等,经过几次跳转,就会出现在跳转的时候又回到这个首页http://wexin.foxtable.com,总是出现问题。所跳转的网页都是在这个域名之下,但是页面较多,要么就出现多次刷新页面,要么就直接显示空白页面。
