使用 C# 向 SII 提交问题 EnvioDTE

Question

我正在使用 C# 将 Envio DTE 提交到智利的 SII。

现在我收到 html 回复，并收到此

"HA OCURRIDO UN ERROR EN EL UPLOAD DEL ARCHIVO DE DOCUMENTOS TRIBUTARIOS ELECTRONICOS."

我认为参数传递不正确。参数名称在他们的文档中是正确的。此请求应模拟网络浏览器。

如果有人能帮助我，我将不胜感激。 代码：

       public string SendEnvioDte(string fileName, string token, Documento documento, string userRut)
       {
            string boundary = "----------------------------" + DateTime.Now.Ticks.ToString("x");
            
            NameValueCollection nvc = new NameValueCollection();

            var RutEmisor = documento.Encabezado.Emisor.RUTEmisor;
            var RutReceptor = documento.Encabezado.Receptor.RUTRecep;
            var rutSender = userRut.Substring(0, 8);
            var senderDv = userRut.Substring(8);
            var rutCmopany = RutEmisor.Substring(0, 8);
            var rutCompnaydv = RutEmisor.Substring(9);

Answer 1

应该是tcp/ip套接字通信加密数据模拟浏览器

Answer 2

改变

System.Text.Encoding.UTF8.GetBytes()
System.Text.Encoding.ASCII.GetBytes()

由

System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes()

应该可以。
