AtTask接口上传文件

Question

我正在尝试将文件上传到AtTask，但我继续收到非法参数异常。我已经阅读了文档，并相信我有正确的代码，但我无法让它工作。有没有人有可以上传文件到AtTask的C#代码？下面是我的代码以供参考：

        BinaryReader br = new BinaryReader(fs);
        int bufferSize = 40960; //Amount of data that to be read from file(in bytes)
        byte[] buffer = br.ReadBytes(bufferSize);//reading the bytes
        string str = Convert.ToBase64String(buffer);

        string boundary = "----MyAppBoundary" + DateTime.Now.Ticks.ToString("x");

        var request = (HttpWebRequest)WebRequest.Create(fullUrl);
        request.ContentType = "multipart/form-data; boundary=" + boundary;
        request.Method = "POST";

        using (var requestStream = request.GetRequestStream())
        using (var writer = new StreamWriter(requestStream))
        {
            writer.WriteLine(string.Format("Content-Disposition: form-data; name=\"{0}\"", "uploadedFile"));
            writer.WriteLine();
            writer.WriteLine(str);                
        }

        using (WebResponse response = request.GetResponse())
        {
            using (Stream responseStream = response.GetResponseStream())
            {
                return ReadResponse(responseStream);
            }
        }

确保您显式地指定了您的字符集(我一直使用UTF-8)。我从未通过Java上传过C#，但我有(生产系统函数式) AtTask示例，如果这会有帮助的话。下面是我用来指定字符集的一个简短示例。

writer.append("Content-Disposition: form-data; name=\"" + name + "\"")
      .append(LINE_FEED);
writer.append("Content-Type: text/plain; charset=UTF-8")
      .append(LINE_FEED);
