帮我看看这段代码

[wasfer]

Dim request As WebRequest = WebRequest.Create("http://192.168.0.219:81/WebService.asmx/UserLogin")

request.Method = "POST"

Dim postData As String = "UserName=andy&UserPassword=123123&macadd=Client/Server"
Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postData)

request.ContentType = "application/x-www-form-urlencoded"

request.ContentLength = byteArray.Length

Dim dataStream As Stream = request.GetRequestStream()

dataStream.Write(byteArray, 0, byteArray.Length)

dataStream.Close()

Dim response As WebResponse = request.GetResponse()

Console.WriteLine(CType(response, HttpWebResponse).StatusDescription)

dataStream = response.GetResponseStream()

Dim reader As New StreamReader(dataStream)

Dim responseFromServer As String = reader.ReadToEnd()

MsgBox(responseFromServer)

reader.Close()
dataStream.Close()
response.Close()



接口返回值报错乱码，怎么解析返回值乱码？

[moonwrite]

Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postData) 你怎么知道就是UTF8呢~ request.ContentType = "application/x-www-form-urlencoded" 还有这个~~~

问题已经解决了 如果要post json格式到一个接口，这种方法行吗？今天弄了半天 值传不过去。是什么问题？
