【高分求解】UTF8编码JSP通过GET方式接受GBK乱码
各位好，在下遇到个问题，请教大大们解决下
我们知道“中国”这个词的 utf-8编码为 %E4%B8%AD%E5%9B%BD 而 gbk编码为 %D6%D0%B9%FA
现在小弟有个jsp页面是utf-8编码的
<%@ page language="java" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8" errorPage="../error.jsp" %>
String ttee = new String(request.getParameter("name").getBytes("utf-8"), "gbk");
ttee = new String(ttee.getBytes("gbk"), "utf-8");
//结果乱码
//直接
ttee = new String(request.getParameter("name")); //也是乱码
String s3 = sb.substring(16);
byte b0 = Integer.valueOf(s1, 2).byteValue();
byte b1 = Integer.valueOf(s2, 2).byteValue();
byte b2 = Integer.valueOf(s3, 2).byteValue();
byte[] bf = new byte[3];
bf[0] = b0;
bf[1] = b1;
bf[2] = b2;
fullByte[i * 3] = bf[0];
fullByte[i * 3 + 1] = bf[1];
fullByte[i * 3 + 2] = bf[2];
}
return fullByte;
}
[解决办法]
Get限制Form表单必须为ASCII字符，而url拼好后，浏览器会先URL encode，然后发送给服务器，到底是按照那种编码方式对字符编码，LZ你可以尝试下用IE、CHROME、FIREFOX等打开试试不同处.
解决方法①：浏览器会根据操作系统设置进行编码，需要将操作系统(控制面板-区域和语言选项)regional options中的 Chinese (PRC) 改成UNITE STATE ，再试试 。
解决方法②：uri = encodeURI(uri)在url encode之前再对其编码一次，这样url里面的字符都是ISO-8859-1了。才能正常转码String s = new String(request.getParameter("name").getBytes("ISO-8859-1"),"UTF-8");
仅供参考.
