Python REST API UnicodeDecodeError。 C＃客户端

Question

我在ASP MVC Web应用程序中有一个控制器，试图将文档上传到Opentext eDocs REST API。

这是我的方法

var uri = ConfigurationManager.AppSettings["eDocsEndpoint"] + "documents?library=EDOCS_TEST";
            var cookieContainer = GetCookies(ConfigurationManager.AppSettings["eDocsUser"], ConfigurationManager.AppSettings["eDocsPassword"], ConfigurationManager.AppSettings["eDocsLibrary"]);

            using (var handler = new HttpClientHandler() { CookieContainer = cookieContainer })
            {
                using (var client = new HttpClient(handler) { BaseAddress = new Uri(uri) })
                {
                    FileStream fileStream;
                    StreamContent streamContent;

                    using (fileStream = System.IO.File.OpenRead("C:\\Temp\\Test.docx"))
                    {
                        var memStream = new MemoryStream();
                        memStream.SetLength(fileStream.Length);
                        fileStream.Read(memStream.GetBuffer(), 0, (int)fileStream.Length);
                        streamContent = new StreamContent(memStream);
                    }

                    using (var form = new MultipartFormDataContent())
                    {
                        var values = new[]
                        {
                            new KeyValuePair<string, string>("DOCNAME", "DOCNAME"),
                            new KeyValuePair<string, string>("AUTHOR_ID", "MYUSER"),
                            new KeyValuePair<string, string>("CLIENT_ID", "DEFAULT"),
                            new KeyValuePair<string, string>("MATTER_ID", "DEFAULT"),
                            new KeyValuePair<string, string>("TYPIST_ID", "MYUSER"),
                            new KeyValuePair<string, string>("APP_ID", "MS WORD"),
                            new KeyValuePair<string, string>("TYPE_ID", "DEFAULT")
                        };


                        foreach (var keyValuePair in values)
                        {
                            form.Add(new StringContent(keyValuePair.Value,Encoding.UTF8),
                                String.Format("\"{0}\"", keyValuePair.Key));
                        }
                        streamContent.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");  
                        form.Add(streamContent, "\"file\"", string.Format("\"{0}\"", "TEST"));
                        try
                        {
                            var response = client.PostAsync("documents?library=" + ConfigurationManager.AppSettings["eDocsLibrary"], form).Result;
                            if (!response.IsSuccessStatusCode)
                            {
                                //TODO
                            }
                            return Json("Success", JsonRequestBehavior.AllowGet);
                        }
                        catch (Exception ex)
                        {
                            return Json("Failed", JsonRequestBehavior.AllowGet);
                        }
                    }
                }
            }

我还在运行REST API的服务器中调试。这是错误：

Traceback (most recent call last):
  File "C:\Python27\lib\logging\__init__.py", line 861, in emit
    msg = self.format(record)
  File "C:\Python27\lib\logging\__init__.py", line 734, in format
    return fmt.format(record)
  File "C:\Python27\lib\logging\__init__.py", line 465, in format
    record.message = record.getMessage()
  File "C:\Python27\lib\logging\__init__.py", line 329, in getMessage
    msg = msg % self.args

    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xd2 in position 1392: invalid continuation byte

我可以使用python脚本上载文档，但是我需要在此ASP NET C＃Web应用程序中使用它。
