验证函数
Dim e As RequestEventArgs = args(0)
Dim UserId As String
Dim sb As New StringBuilder
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
If UserId > "" then'授权成功
e.AppendCookie("userid",UserId) '将userid和username存储在Cookie中
Return UserId
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 ul1 As String = "https://open.weixin.qq.com/connect/oauth2/authorize?appid={0}&redirect_uri={1}&response_type=code&scope=SCOPE&agentid=AGENTID&state=STATE#wechat_redirect"
Dim ul2 As String = UrlEncode("http://www.664748.com:8083/getuserid.htm")
ul1 = CExp(ul1,"ww95bdb1894744965a",ul2)
sb.Append("<meta http-equiv='Refresh' c>") '跳转到授权链接
e.WriteString(sb.ToString)
Return ""
End If
需要使用的时候这样：
if e.host = "www.664748.com" Then '需要授权才能访问的域名
If e.path = "aaa.htm"
dim userid = Functions.Execute("验证函数",e)
if userid > "" then
验证成功的代码
else
验证不成功的代码
end if
end if
end if
