今天朋友注册会员账号使用了中文,登陆后发现用户名变成了乱码,后来发现是因为账号直接用cookie保存的,而cookie对中文不支持才导致乱码的情况。下面的代码是在网上找的
设置cookie时:
HttpCookie cookie = Request.Cookies["UserName"];
if (Session["UserName"] != null)
{
string userName = Server.UrlEncode(Session["UserName"].ToString());
if (cookie != null)
{
cookie.Value = userName;
//cookie.Expires = DateTime.Now.AddDays(1);
cookie.Domain = BasePage.DomainName;
Response.Cookies.Set(cookie);
}
else
{
cookie = new HttpCookie("UserName");
cookie.Value = userName;
//cookie.Expires = DateTime.Now.AddDays(1);
cookie.Domain = BasePage.DomainName;
Response.Cookies.Add(cookie);
}
}
获取cookie时:
private string _loginUserName;
public string LoginUserName
{
get
{
if (Session["UserName"] != null && Session["UserName"].ToString() != "")
{
_loginUserName = Session["UserName"].ToString();
}
else if (Request.Cookies["UserName"] != null && Request.Cookies["UserName"].Value != "")
{
_loginUserName = Server.UrlDecode(Request.Cookies["UserName"].Value);
}
else
{
_loginUserName = null;
}
return _loginUserName;
}
}
还有一个条件,即配置文件中需要设置中文格式,如:
<!-- 全球化 此节设置应用程序的全球化设置。 -->
<globalization requestEncoding="GB2312" responseEncoding="GB2312"/>

中文cookie的问题,
在Windows 2000正常,
在Windows 2003 sp1下会偶尔出现乱码(遇到双字节特殊字符时候,例子:「`蹆绌 ),
在windows 2003 SP2下基本乱码
解决办法:
采用
Server.UrlEncode();
Server.UrlDecode();
写入时进行编码:Cookie["MyCookie"] = Server.UrlEncode("中文")
读取时进行解码:Response.Write(Server.UrlDecode(Request.Cookies("MyCookie").Value()))
