主题：短信接口中请在request请求中附带登出后的cookies使用，这是什么意思？

试试这样处理

Dim req = System.Net.WebRequest.Create("http://www.baidu.com")
req.Method = "delete"
Dim cookieCon = new System.Net.CookieContainer
req.CookieContainer = cookieCon
Dim ck As new System.Net.Cookie("username", "123456")
req.CookieContainer.add(new Uri("http://www.baidu.com/"), ck)
Dim pos = req.GetResponse()
Dim stm As System.IO.Stream = pos.GetResponseStream()
Dim reader As New System.IO.StreamReader(stm,encoding.utf8)
Dim str As String = reader.ReadToEnd  
msgbox(str)
stm.Dispose()
