我一直在努力获取正在发送的json正文（用fiddler查看），但我总是得到一个空字符串。

在尝试读取信息之前，设置以下内容：HttpContext.Current.Request.InputStream.Position = 0仍会返回空字符串。

我试图提取此信息的各种方式

Dim myStream As Stream
myStream = HttpContext.Current.Request.InputStream
myStream.Position = 0
Dim myStreamReader As New StreamReader(myStream)
otherText = myStreamReader.ReadToEnd()


Dim bytes = New Byte(objRequest.InputStream.Length - 1) {}
objRequest.InputStream.Position = 0
objRequest.InputStream.Read(bytes, 0, bytes.Length)
otherText = System.Text.Encoding.Default.GetString(bytes)

如何提取我可以用小提琴手查看的这些信息，我探索过的所有途径都会产生相同的结果。空字符串。
