在ASP.NET MVC中发布和读取二进制数据

Question

我在通过HttpWebRequest向服务器发布二进制数据时遇到问题。这是我的客户代码：

var request = (HttpWebRequest)WebRequest.Create(uri);
request.Method = "POST";
request.UserAgent = RequestUserAgent;
request.ContentType = "application/x-www-form-urlencoded";
var responseStr = "";
var dataStr = Convert.ToBase64String(data);
var postData = Encoding.UTF8.GetBytes(
string.Format("uploadid={0}&chunknum={1}&data={2}", uploadId, chunkNum, dataStr));
using (var dataStream = request.GetRequestStream())
{
    dataStream.Write(postData, 0, postData.Length);
    dataStream.Close();
}

然后我想通过MVC控制器处理请求，这是它的签名：

public ActionResult UploadChunk(Guid? uploadID, int? chunkNum, byte[] data)

但我在这里有错误，说数据不是Base64编码数组，我做错了什么？

您需要通过调用+来转义Base64中的Uri.EscapeDataString个字符。
