使用 c# 将问题 EnvioDTE 提交给 SII

Question

我正在使用 C# 将 Envio DTE 提交到智利的 SII。

现在我得到一个 html 响应，并得到一个 this

“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。这个请求应该是模拟网络浏览器。

如果有人能帮助我，我真的很感激。 代码：

Answer 1

改变

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

通过

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

那应该有用。

Answer 2

应该是tcp/ip socket通信加密数据和模拟浏览器。

Answer 3

要进行此提交，您必须使用“MultipartFormDataContent”类并添加所需参数：（自动插入边界） 例如一个字符串：

var form = new MultipartFormDataContent()
{
  { new StringContent(rutenvia), @"""rutSender""" },               
};                                                                
// Add another value to form...

然后，添加到

using var request = new HttpRequestMessage(new HttpMethod("POST"),"https://palena.sii.cl/cgi_dte/UPL/DTEUpload");             
 // Add Token & User-Agent                           
request.Content = form;                                           
 // send to endpoint                                             
 var response = await httpclient.SendAsync(request);
