传递中文产生乱码!生气呀 - 编程论坛

传递之前转化1下就好了

#3

fqj7932007-02-05 11:04

能说具体点吗?怎样转呢?

#4

想你的天空2007-02-05 11:07

String 传之前=
URLUnicode("error.jsp?msg=您的输入有误!"); 这里处理1下，我也记不太清楚了
response.sendRedirect(传之前);

#5

fqj7932007-02-05 11:09

先谢过了,兄弟,我试一下!

#6

しΟν∈→鱈2007-02-05 11:33

在你的整个JSP文件中加个
<meta http-equiv="Content-Type" content = "text/html; charset = gb2312">试试

#7

fqj7932007-02-05 14:38

这个是有的.已经加了,但还是不行.

#8

shenba2007-02-05 22:08

request.setCharaterEncoding("GBK")

#9

fqj7932007-02-06 08:54

8楼的xd,能明确告诉我该如何写吗?String msg=new String(request.getParameter("msg").getBytes("ISO8859_1"),"GBK");语句该怎么写呢?

以下是引用fqj793在2007-2-5 11:00:53的发言：
我使用如下语句:response.sendRedirect("error.jsp?msg=您的输入有误!");error.jsp页面中的接收语句为:String msg=new String(request.getParameter("msg").getBytes("ISO8859_1"),"GBK");可是当显示变量msg的时候就是乱码,各位,请教了!

你在传递前可以转码先
response.sendRedirect("error.jsp?msg=URLEncoder.encode('您的输入有误!')");

#11

fqj7932007-02-06 09:32

还是不行呀!

#12

every2007-02-06 12:51

在接收页面加上request.setCharacter("gb2312")（没写错吧。。）看看行不行。。

#13

我看你把两个页面代码贴上来好了,你这么说永远也不知道你到底哪写的有问题

红色部分为所述代码!

bagger2007-02-06 22:40

request.setCharaterEncoding("GBK")；
或request.setCharaterEncoding("GB2312")；
之后再request
就不会出现中文乱码了

#16

angeloc2007-02-07 08:57

response.sendRedirect("error.jsp?msg=<%=URLEncoder.encode('您好的输入有错误!')%>");
你加上URLEncoder!

#17

fqj7932007-02-07 10:55

我在String msg=new String(request.getParameter("msg").getBytes("ISO8859_1"),"GBK");之前有加这句呀,request.setCharaterEncoding("GB2312")；

#18

风月_无边2007-02-07 13:36

ISO-8859-1 是不是写错了

#19

fqj7932007-02-07 15:32

这一步我做了！

我那种方法你试了么?

也试了，产生错误信息

angeloc2007-02-07 16:27

response.sendRedirect("error.jsp?msg=<%=URLEncoder.encode('?ㄥソ????ユ????!')
你这个写的问题吧!
URLEncoder需要引入java.net.URLEncoder

#23

fqj7932007-02-08 15:59

问题还是没有解决!

#24

lgdcky2007-02-19 22:33

这个问题我也遇到过!其实只要把你要传递的信息先放到一个String里,
String urlr = "您的输入有误";
<p align='center'><a href='text.jsp?msg="+urlr+"'>" + name + "</a></p>"
然后在传过去之后进行如下转换
String url = request.getParameter("msg");
String urle = new String(url.getBytes("ISO-8859-1"),"GBK");

#25

zhupeng2007-02-23 21:30

一般都用ＧＢＫ吧你怎么又用ＧＢＫ又用ＧＢ２３１２啊

#26

独孤无痕2007-02-27 20:32

加个filtter试试!!

#27

wsn2007-03-03 17:26

据说utf8就不会了

#28

ILoveMK2007-03-03 23:36

在代码中加入这句话response.setContentType("text/html;charset=UTF8");

然后找到 server.xml 中的
<Connector port="8080" maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" URIEncoding='UTF8' />

加入红色部分代码，这样应该就行了。
如果还不行就把上面的UTF8全部替换成GBK.

#29

球球2007-03-08 22:24

String msg=new String(request.getParameter("msg").getBytes("iso-8859-1"));

"iso-8859-1"

#30

fqj7932007-03-08 23:25

我不是这样传回中文,我是要从这里传回:response.sendRedirect("error.jsp?msg=您的输入有误!");
error.jsp页面中的接收语句为:String msg=new String(request.getParameter("msg").getBytes("ISO8859_1"),"GBK");

#31

球球2007-03-09 11:16

"ISO8859_1"改成"iso-8859-1"试试

#32

你这里用的是get方式所用要配置server，不过好像在程序里也可以加段代码，也行但我把那个方法给忘了

#33

心动音符2007-03-11 22:37

老弟我也有个关于乱码的问题：
我想把内容（有中文）通过hibernter持久到数据库（MySql）中，代码可以成功执行但我到数据库中通过selest语句查询发现都是“问号”？
－－我在数据库建表的时候用了mysqld --character_set_server=gb2312;
在XML的URL配置信息里也加了jdbc:mysql://localhost/dbname?useUnicode=true;characterEncoding=gb2312
但还是不行不知道为啥？我程序中所保存的中文是gb2312的
