微信接口那里access_token的代码写在哪里啊?
Static
CreateTime
As
Date
'记录最近一次生成access_token的时间
Static AccessTocken As
String
'记录最近一次生成的access_token
Dim AppId
As
String=
"wx8acdb7df5beb68fd"
'开发者ID
Dim AppSecret As
String = "a5a3b06a790d4200a151e6b13c3dc263"
'开发者密匙
Dim tp As TimeSpan = Date.Now -
CreateTime
Dim url As
String = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={0}&secret={1}"
If tp.TotalSeconds > 3600
Then
Dim hc As New HttpClient(CExp(url,AppId,AppSecret))
Dim ret As
String = hc.GetData()
If
ret = ""
Then
'如果失败,再尝试一次
hc.GetData()
End
If
CreateTime = Date.Now()
Dim
jo As JObject = JObject.Parse(ret)
If jo("errcode") Is
Nothing
Then
AccessTocken =
jo("access_token")
Else
MessageBox.show("获取access_token失败,原因:" & vbcrlf & jo("errmsg").ToString)
End
If
End
If
Return
AccessTocken
