巧用escape解决ASP.NET中URL传参乱码问题
1
<a href="#" onclick="window.open('http://www.mzwu.com/test.aspx?title=木子屋');">Links</a>
<a href="#" onclick="window.open('http://www.mzwu.com/test.aspx?title=木子屋');">Links</a>在test.aspx中，只要获取title参数的值并显示出来即可，本来用Request["title"]就可解决的问题却因链接所处页面的编码不同而变得复杂起来：
当链接所处的页面是用GB2312编码时，如果test.aspx也是GB2312则获取的参数值不乱码，否则乱码；
当链接所处的页面是用UTF-8编码时，如果test.aspx也是UTF-8则获取的参数值不乱码，否则乱码；
gb.htm：
1<html>
2<head>
3<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
4<title>gb2312测试页</title>

{

String Request1;
4 Request1 = Request["title"];
5 Response.Write(Request1);
6
}
private void Page_Load(object sender, System.EventArgs e)2
{

String Request1;4
Request1 = Request["title"];5
Response.Write(Request1);6
}有没办法让test.aspx不论URL中的参数以何种方式编码都能正常的获取显示呢？通过配置web.config的<globalization requestEncoding="gb2312|utf-8" />都只会顾此失彼，不能完美的解决我们的问题。最终，在老农的提示下使用JS的escape问题得以完美解决：
gb.htm：
1<html>
2<head>
3<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
4<title>gb2312测试页</title>

</html>现在完全不用考虑链接所在页面的编码方式，也不用绞尽脑汁去想如何在test.aspx对不同编码的参数值进行转换，只需用一个escape就够了，very good!
