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

                    + "recordImgs/";
            File recf = new File(uploadPath);
            recf.mkdirs();
            String urlPath = Tools.getStrutsProp().getValue("urlPath")
                    + "recordImgs/";

                result = result.replace(key, urlPath + fileName);
            }
