之前是按照下面的方式写的，现在有post数据提交，想改，不知道怎么把json数据传出去

 

Dim name As String=Functions.Execute("utf8",e.Form.controls("TextBox1").text)

Dim id As String=e.Form.controls("TextBox2").text

 

Dim time As String =DateDiff("s", "01/01/1970 00:00:00", Now())

Dim msg As String = "username=" & name &"&idcard=" & id & "&_=" & time

Dim req = System.Net.WebRequest.Create("http://zscx.zjsafety.gov.cn/examweb/api/v2/certificate/query_json.xhtml")

req.Method = "POST"

req.Timeout = 5000

req.C

Dim aryBuf As Byte() = Encoding.GetEncoding("GB2312").GetBytes(msg)

req.ContentLength = aryBuf.Length

Dim writer = req.GetRequestStream()

writer.Write(aryBuf, 0, aryBuf.Length)

writer.Close()

writer.Dispose()

Dim pos = req.GetResponse

Dim stm As System.IO.Stream = pos.GetResponseStream()

Dim reader As New System.IO.StreamReader(stm)

Dim str As String = reader.ReadToEnd

pos.Close

stm.Close

reader.close

 

Dim name As String="张三"
Dim id As String="abc"
Dim time As String =DateDiff("s", new Date(1970, 1, 1), Now())
Dim msg As String = "username=" & name &"&idcard=" & id & "&_=" & time
msgbox(msg)
Dim req = System.Net.WebRequest.Create("https://zscx.zjsafety.gov.cn/examweb/api/v2/certificate/query_json.xhtml")
req.Method = "POST"
req.Timeout = 5000
req.ContentType = "application/x-www-form-urlencoded; charset=UTF-8"
req.UserAgent = "Mozilla/5.0 (Windows NT 6.3; rv:66.0) Gecko/20100101 Firefox/66.0"
Dim aryBuf As Byte() = Encoding.GetEncoding("utf-8").GetBytes(msg)
req.ContentLength = aryBuf.Length
Dim writer = req.GetRequestStream()
writer.Write(aryBuf, 0, aryBuf.Length)
writer.Close()
writer.Dispose()
Dim pos = req.GetResponse
Dim stm As System.IO.Stream = pos.GetResponseStream()
Dim reader As New System.IO.StreamReader(stm)
Dim str As String = reader.ReadToEnd
pos.Close
stm.Close
reader.close

msgbox(str)

Dim name As String="张三"
Dim id As String="abc"
Dim hc As New HttpClient("https://zscx.zjsafety.gov.cn/examweb/api/v2/certificate/query_json.xhtml")
hc.contentType = "application/x-www-form-urlencoded; charset=UTF-8"
hc.Timeout = 5 '设置超时为5秒
Dim time As String =DateDiff("s", new Date(1970, 1, 1), Now())
Dim msg As String = "username=" & name &"&idcard=" & id & "&_=" & time
hc.Content = msg
Dim ret As String = hc.GetData()
MessageBox.Show(ret)

太感谢了
