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？

1、登陆后返回的数据是什么？

Dim ret As String = hc.getData()

msgbox(ret)

2、帮助文档怎么说的？把帮助文档弄出来看看；

3、是不是这样？ http://www.foxtable.com/mobilehelp/scr/0158.htm

是不是这样？

Dim hc_send As New HttpClient("http://10.10.10.10:10/delete")

参考代码，论坛搜索 HttpWebRequest 看具体使用

Dim url As String = "http://www.baidu.com"
Dim rqst As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(url)
rqst.Method = "delete"
Dim rsps As System.Net.HttpWebResponse = rqst.GetResponse
Dim stm As System.IO.Stream = rsps.GetResponseStream()
Dim reader As New System.IO.StreamReader(stm,encoding.utf8)
Dim str As String = reader.ReadToEnd  
stm.Dispose()
Return(str)

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()

Dim req = System.Net.WebRequest.Create("http://10.10.10.10:10/session")
req.Method = "DELETE"
Dim cookieCon = new System.Net.CookieContainer
req.CookieContainer = cookieCon
Dim ck As new System.Net.Cookie("TWIST_SESSION", "123456")
req.CookieContainer.add(new Uri("http://10.10.10.10"), 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
stm.Dispose()

msgbox(str)

此主题相关图片如下：1.png

  <!--[endif]-->errorcode  = -20的意思对应：    ERROR_NOT_LOGGED_IN = -20

提示是请先登录，说明你cookie值不对导致的，认真核对和测试。

1、你的delete方法是否可以正常执行？

2、执行代码后报什么错？

3、细节问题，请自行咨询设备厂家。

直接叫厂家给你发c#或者vb.net的代码。
