非法字符 - CTRL-CHAR [英] Illegal character - CTRL-CHAR

问题描述

我收到来自网络服务的以下异常:

I am getting following exception from webservices:

com.ctc.wstx.exc.WstxUnexpectedCharException: 非法字符 ((CTRL-CHAR, code 15))

com.ctc.wstx.exc.WstxUnexpectedCharException: Illegal character ((CTRL-CHAR, code 15))

我知道这背后的原因，我得到了控制字符"；在我想返回的数据中.并且在 XML 中 CTRL-CHAR 是不允许的.

I know the reason behind this, I am getting "Control Characters" in data I want to return. And in XML CTRL-CHAR are not allowed.

我搜索了解决方案，在很多地方我找到了删除CTRL-CHAR的代码.

I searched for the solution, and many places I found the code to remove CTRL-CHAR.

担心的是，如果我从数据中删除控制字符，我最终会丢失数据吗?
我想要干净的解决方案可能编码，而不是删除控制字符.

The concern is shall I end up loss of data if I remove control characters from data?
I want the clean solution may encoding, instead of removing control char.

推荐答案

感谢大家的投入.我正在分享解决方案可能对其他人有帮助.要求不是消除 CONTROL CHAR，它也应该保持在 DB 中的原样，并且一个 WS 通过 n/w 客户端发送它应该能够获得 CONTROL CHAR.所以我实现了如下代码:

Thanks guys for you inputs. I am sharing solution might be helpful for others. The requirement was not to wipe out CONTROL CHAR, it should remain as it is in DB also and one WS sends it across n/w client should able to get the CONTROL CHAR. So I implemented the code as follow:

1. 在 Web 服务代码中使用 URLEncoder 对字符串进行编码.
2. 在客户端使用 URLDecoder 对其进行解码

在下面分享示例代码和输出.
示例代码:

Sharing sample code and output bellow.
Sample code:

System.out.println("NewSfn");  
System.out.println(URLEncoder.encode("NewSfn", "UTF-8"));  
System.out.println(URLDecoder.decode("NewSfn", "UTF-8"));  

输出:

NewSfn  
New%0FSfn  
NewSfn 

因此客户端将收到控制字符.

So client will recieve CONTROL CHARs.

堆栈交换没有显示上面的控制字符.NewSfn 就是这样的New(CONTROL CHAR)Sfn.

Stack Exchange is not showing CONTROL CHAR above. NewSfn is like this New(CONTROL CHAR)Sfn.
