在 ASP.NET MVC 中发布和读取二进制数据
我在通过 HttpWebRequest 将二进制数据发布到服务器时遇到问题。这是我的客户端代码：
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)
但我这里有错误，说数据不是 Base64 编码数组，我做错了什么？
I have a problem with posting of binary data to server via HttpWebRequest. Here is my client code:
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();
}
And then I want to work with request via MVC controller, here is it's signature:
public ActionResult UploadChunk(Guid? uploadID, int? chunkNum, byte[] data)
But I have error here, saying that data is not Base64 coded array, what am I doing wrong?

您需要通过调用
Uri.EscapeDataString对 Base64 中的+字符进行转义。You need to escape the
+characters in your Base64 by callingUri.EscapeDataString.
