AS3 Post 参数和ByteArray的方法及服务器端接收

as端: (form表单形式)
req.method = URLRequestMethod.POST;

var reqHeader:URLRequestHeader = new URLRequestHeader("Content-type", "application/x-www-form-urlencoded");

req.requestHeaders.push(reqHeader);

........ -->by; 
var param:URLVariables = new URLVariables();
var encoder:Base64Encoder = new Base64Encoder();

encoder.encodeBytes(by);

param.data = encoder.toString();
param.content = "上面这个by是二进制数组,如图片等"; 
req.data = param;
UrlLoader.load(URLRequest);

C#端接收:

System.IO.Stream s = System.Web.HttpContext.Current.Request.InputStream;

int count = 0;

byte[] buffer = new byte[1024];

StringBuilder builder = new StringBuilder();

while ((count = s.Read(buffer, 0, 1024)) > 0)

{

        builder.Append(Encoding.UTF8.GetString(buffer, 0, count));

}

........
urlStr = "....."

string text= System.Web.HttpUtility.UrlDecode(urlStr, System.Text.Encoding.UTF8);

byte[] bpath = Convert.FromBase64String(text);

string filePath = "图片123.jpg";

Stream stream = new MemoryStream(bpath);

using (Bitmap b = new Bitmap(stream))

{

     b.Save(filePath, ImageFormat.Jpeg);

}

由于服务器端从URL取出的字符串urlStr 是经过URL编码的，所以需要使用 System.Web.HttpUtility.UrlDecode进行解码成UTF-8
