java post数据问题

Question

我用java写的程序~ 
post提交数据给网站但是提交的文字要用URL编码 
比如 人 提交的是 %C8%CB 
而我想用 xm=人 
java.net.URLEncoder.encode(xm,"UTF-8"); 
来转换下 但是老是转换不了 请问我哪里错了

Answer 1

你试试
java.net.URLEncoder.encode(new String(xm.getBytes(),"GB2312"),"UTF-8");  

Answer 2

System.out.println( "人=" +java.net.URLDecoder.decode("%C8%CB","gb2312")); 

Answer 3

%C8%CB 是按照gb2312来转的.
java.net.URLEncoder.encode(xm,"gb2312");
其实你可以简单测试一下
System.out.println(java.net.URLDecoder.decode("%C8%CB","gb2312")); 如果按照java.net.URLEncoder.encode(xm,"UTF-8");  
来转的话,应该得到%E4%BA%BA
System.out.println(java.net.URLDecoder.decode("%E4%BA%BA","UTF-8"));
