聊天记录解密

其实这个功能的总思路是 包所有的QQ聊天记录和旺旺的聊天记录先拷贝到word，让word把图片进行base64的加密，切记word保存时候的格式是mht的

比如我保存了一份聊天记录，用notepad++打开

可以看到在<!--StartFragment-->

<!--EndFragment-->标签内容才是你拷贝的内容图片后面的src是content-Location后面的字符

后面我们就是解析了

public String newAddServeRecord() {

InputStreamReader r = null;
BufferedReader br = null;
try {
String uploadPath = Tools.getStrutsProp().getValue("uploadPath")
+ "recordImgs/";
File recf = new File(uploadPath);
recf.mkdirs();
String urlPath = Tools.getStrutsProp().getValue("urlPath")
+ "recordImgs/";

r = new InputStreamReader(new FileInputStream(mhtFile), "UTF-8");
br = new BufferedReader(r);

String result = "";
Map<String, String> imgMap = new HashMap<String, String>();

String startFragment = "<!--StartFragment-->";
String endFragment = "<!--EndFragment-->";
String base64 = "Content-Transfer-Encoding: base64";
String location = "Content-Location: ";

String str = null;
while ((str = br.readLine()) != null) {
if (str.indexOf(startFragment) != -1) {

if (str.indexOf(endFragment) != -1) {
result += str.substring(str.indexOf(startFragment)
+ startFragment.length(),
str.indexOf(endFragment));
} else {
result += str.substring(str.indexOf(startFragment)
+ startFragment.length(), str.length());
}
}

if (str.indexOf(endFragment) != -1) {
result += str.substring(0, str.indexOf(endFragment));
}

if (str.indexOf(base64) != -1) {
String locationPath = br.readLine();
locationPath = locationPath.replace(location, "");

br.readLine();
String base64Img = br.readLine();
imgMap.put(locationPath, base64Img);
}

}

result = result.replaceAll("=20", " ").replaceAll("=3D", "=")
.replaceAll("<IMG", "<img");

for (String key : imgMap.keySet()) {
byte[] imgByte = Base64.decode(imgMap.get(key));

String fileName = Tools.getDateToSEC() + Tools.getThree()
+ key.substring(key.lastIndexOf("."));

FileOutputStream imgOut = new FileOutputStream(uploadPath
+ fileName);
imgOut.write(imgByte);
imgOut.close();
result = result.replace(key, urlPath + fileName);
}

// 写入数据库

ServeRecord sr = new ServeRecord();
sr.setDate(new Date());
sr.setContent(result);
sr.setServeCustomer(((Admin) getSession().get(Constant.ADMIN))
.getName());
sr.setCustomerId(customer.getId() + "");
serveRecordDao.insert(sr);
state = "okrecord";
} catch (Exception e) {
logger.error("CustomerManagerAction.newAddServeRecord", e);
return ERROR;
} finally {
try {
if (null != br) {
br.close();
}
if (null != r) {
r.close();
}
} catch (IOException e) {
logger.error(
"CustomerManagerAction.newAddServeRecord[close] error!",
e);
return ERROR;
}
}
return SUCCESS;
}
