在Asp.net的HttpCookie中写入汉字,读取值为什么全是乱码?其实这是因为文字编码而造成的,汉字是两个编码,所以才会搞出这么个乱码出来!其实解决的方法很简单:只要在写入Cookie时,先将其用Url编码,然后再写入,当我们读取时再解码就OK了,希望更多的学生妹妹能解决它,呵呵!
例子:
Cookie的写入:
1HttpCookie cookie=new HttpCookie("Simple");
2cookie.Values.Add("Simple1",HttpUtility.UrlEncode("大叔,你好!"));
3cookie.Values.Add("Simple2","English is OK!Nothing we should do!");
4Response.AppendCookie(cookie); Cookie的读取:
1HttpCookie cookie=Request.Cookies["Simple"];
2string simple1=HttpUtility.UrlDecode(cookie["Simple1"]);
3string simple2=cookie["Simple2"]; 这样simple1="大叔,你好!";simple2="English is OK!Nothing we should do!";
下面是没用过的资料
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;
}
}
