3、Foxtable端的HttpRequst事件代码为:
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
End
If
Dim Verified As
Boolean
Dim dr As
DataRow =
DataTables("Users").Find("userid ='"
& UserId &
"'") '根据openid找出对应的行
If
UserId > ""
AndAlso dr
IsNot
Nothing
AndAlso dr("permit") =
True
'授权成功
Verified = True
UserName = dr("name")
e.AppendCookie("userid",UserId)
'将userid和username存储在Cookie中
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=wxa31aba4cd83af57e&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("欢迎" & UserName &
" , <a
href='http://wexin.foxtable.com'>刷新页面</a>")
End
If
e.WriteString(sb.ToString)
End
If
像这种网页授权的服务器,可以用异步函数么?
按帮助这种直接放HttpRequst事件里面,同时访问的用户数多的情况服务器会不会卡死?
