问题描述

我无法解码附件.类似于 =?utf-8?B?MS5qcGc = 进行编码.我需要解码该附件.我用来解码的Java代码

I am unable to decode the attachment. It something like =?utf-8?B?MS5qcGc= which is encoded. I need to decode that attachment. The java code i am using to decode

private static String decodeName(String name) throws Exception {
  if (name == null || name.length() == 0) {
   return "unknown";
  }
  String ret = java.net.URLDecoder.decode(name, "UTF-8");

  // also check for a few other things in the string:
  ret = ret.replaceAll("=\\?utf-8\\?q\\?", "");
  ret = ret.replaceAll("\\?=", "");
  ret = ret.replaceAll("=20", " ");

  return ret;
 }

请帮我解码.

Please help me out for decoding.

推荐答案

这是UTF-8编码的String:

编码:

That is a UTF-8 encoded String:

Encoding:

String strName ="Attachment";
try { strName = MimeUtility.encodeText(oAttachment.getName(),"utf-8",null); }
catch (UnsupportedEncodingException oException) { LOGGER.error(oException); }

解码:

Decoding:

String strDecoded = MimeUtility.decodeText(strEncoded);

请删除该字符串修改内容.这不是必需的，也不是处理字符串值的正确方法.

please delete that String modifying stuff. That is not needed and not a proper way to deal with string values.
