将curl转换为ASP.NET

您必须设置请求主体,例如:

Public Function GetRemoteURL(getURL As String) As String
    Dim objReq As HttpWebRequest
    Dim objRsp As HttpWebResponse = Nothing
    Dim objRdr As StreamReader
    Dim objRes As String = "" 
    Try
        objReq = DirectCast(WebRequest.Create(getURL), HttpWebRequest)

        objReq.Method = "POST"
        Dim postData = "f=@example.pdf"
        Dim encoding As New ASCIIEncoding()
        Dim bytes = encoding.GetBytes(postData) 
        objReq.ContentLength = bytes.Length
        Dim stream = objReq.GetRequestStream()
        stream.Write(bytes, 0, bytes.Length)

        objRsp = DirectCast(objReq.GetResponse(), HttpWebResponse)
        objRdr = New StreamReader(objRsp.GetResponseStream())
        objRes = objRdr.ReadToEnd()
    Catch
        objRes = ""
    Finally
        If Not objRsp Is Nothing Then objRsp.Close()
    End Try
    Return objRes.ToString()
End Function

注意:我没有测试这个,所以它可能无法直接工作。
