乱码的问题，折腾两天了，还是解决不了，思归，孟子，秋枫等高人请进

我用C#调用一个Servlet，Servlet中从header中取出的中文信息都是乱码，不管我怎么转换，都不行

C#代码如下：
try
{
System.Text.ASCIIEncoding encoding = new ASCIIEncoding();
byte[] data = encoding.GetBytes("");
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:8080/Biometrics/CheckPasswordServlet");
req.Method="POST";
req.Headers.Add("UserID","中国人");
req.Headers.Add("HospitalID", "1");
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = data.Length;
Stream newStream=req.GetRequestStream();
// Send the data.
newStream.Write(data,0,data.Length);
newStream.Close();

HttpWebResponse res = (HttpWebResponse)req.GetResponse();
}catch(Exception ex)
{
textBox1.Text = ex.Message;
}

Servlet部分代码如下：
protected int doProcess(HttpServletRequest req, HttpServletResponse res)
throws BiometricsException {
String userID = null;
try {
userID = req.getHeader("UserID").trim();
logger.debug("UserID: " + userID);
userID = new String(userID.getBytes("iso-8859-1"), "GB2312");
logger.debug("UserID: " + userID);

日志中记录的userID都是乱码，这是为何？

saucer(思归)兄，如果我在客户端C#中使用HttpUtility.UrlEncode进行编码了，
那我在Servlet中如何解吗？

req.Headers.Add("UserID",HttpUtility.UrlEncode("中国人", System.Text.Encoding.GetEncoding("GB2312")));

乱码问题，最好用utf-8来编码，最安全

[saucer]

what if you try


req.Headers.Add("UserID",HttpUtility.UrlEncode("中国人", System.Text.Encoding.GetEncoding("GB2312")));

or

req.Headers.Add("UserID",HttpUtility.UrlEncode("中国人", System.Text.Encoding.UTF8));

saucer(思归) 老大正解

hoho，向思归大哥学习……

saucer(思归)兄，我用你提供的方法，怎么接收到的还是乱码阿，晕了

[cxbkkk]

utf-8比较方便，有时候textbox输入的东西读出来的是乱码

[saucer]

try to use java.net.URLDecoder.decode

java.net.URLDecoder.decode("encoded string","the matching encoding here")

[saucer]

you want to try the method in this article?
