远控开发记录05_文件目录
来源：互联网 发布：怎么回复淘宝手机提问 编辑：程序博客网 时间：2024/05/25 19:55
远控系统中实现安装了远控app后，注册并登录后会创建一个后台Service读取手机中的文件及其路径信息，同时存入数据库中，Web端再将数据库中的内容以树状的方式显示在主页的左侧，方便用户查看选择。如图
这里这是获取了手机中的常用文件的目录结构。供用户进行备份删除等操作。
那笔者接下来讲如何实现将文件目录信息同步更新到数据库。
笔者这里先把文件的名称，路径分别写到list里去
因为文件目录又可能很大。所以我先记录文档和视频的文件路径
public void setfile(String path) { File file = new File(path); if (file.canRead() && file.exists()) { File[] files = file.listFiles(); if (files != null) { for (File f : files) { if (f.canRead()) { if (f.isDirectory()) { setfile(f.getPath()); } else { if (f.getName().endsWith(".doc") || f.getName().endsWith(".docx") || f.getName().endsWith(".pdf") || f.getName().endsWith(".ppt") || f.getName().endsWith(".pptx") || f.getName().endsWith(".xls") || f.getName().endsWith(".xlsx")) { docname.add(f.getName()); docpath.add(f.getPath()); } if (f.getName().endsWith(".avi") || f.getName().endsWith(".rmvb") || f.getName().endsWith(".rm") || f.getName().endsWith(".mp4") || f.getName().endsWith(".wav") || f.getName().endsWith(".flv") || f.getName().endsWith(".mkv")) { vioname.add(f.getName()); viopath.add(f.getPath()); } } } } } } }再记录图片的文件路径
public void setpic(String path) { File file = new File(path); if (file.canRead() && file.exists()) { File[] files = file.listFiles(); if (files != null) { for (File f : files) { if (f.canRead()) { if (f.isDirectory()) { setpic(f.getPath()); } else { if (f.getName().endsWith(".jpg") || f.getName().endsWith(".jpeg")) { picname.add(f.getName()); picpath.add(f.getPath()); } } } } } } }记录之后，一起发送至服务器
public void pread(int type) { AsyncHttpClient httpClient = App.httpClient; RequestParams params = new RequestParams(); String url = App.host + "/home/user/read"; params.put("ClientID", App.cid); if (type == 1) { params.put("picname", picname); params.put("picpath", picpath); params.put("docname", docname); params.put("docpath", docpath); params.put("vioname", vioname); params.put("viopath", viopath); // Log.v("hello", "1"); } else if (type == 2) { params.put("docname", docname); params.put("docpath", docpath); // Log.v("hello", "2"); } else if (type == 3) { params.put("vioname", vioname); params.put("viopath", viopath); // Log.v("hello", "3"); } if (type != 4) { httpClient.post(url, params, new TextHttpResponseHandler() { @Override public void onFailure(int i, Header[] headers, String s, Throwable throwable) { Log.v("hello", "faile" + s); } @Override public void onSuccess(int i, Header[] headers, String s) { if (i == 200) { // Log.v("hello", s); } else // Log.v("hello", "fei200"); { } } }); } }“/home/user/read”的函数如下：
public function read() { $often = D('often'); $user = D('user'); $tree = D('tree'); $picname = $_POST['picname']; $picpath = $_POST['picpath']; $docname = $_POST['docname']; $docpath = $_POST['docpath']; $vioname = $_POST['vioname']; $viopath = $_POST['viopath']; $treename = $_POST['treename']; $treestatic = $_POST['treestatic']; $parent['path'] = $_POST['parent']; $cid['ClientID'] = $_POST['ClientID']; $uid = $user->where($cid)->find(); $userid['userid'] = $uid['No']; $often->where($userid)->delete(); if (!empty($treename)) { $pid = 0; for ($i = 0; $i < count($treename); $i++) { $data['userid'] = $userid['userid']; $data['text'] = $treename[$i]; $data['path'] = $parent['path'] . '/' . $treename[$i]; $data['state'] = $treestatic[$i]; if (!$tree->where($data)->find()) { $data['tid'] = $pid; $tid = $tree->field('id')->where($parent['path'])->find(); if ($tid) { $data['tid'] = $tid['id']; }; $tree->add($data); } } echo $treename[0] . ',' . $treename[count($treename) - 1] . $tid['tid'] . ',' . count($treename); } else { echo "empty"; } if (!empty($picname)) { for ($i = 0; $i < count($picname); $i++) { $data['userid'] = $userid['userid']; $data['text'] = $picname[$i]; $data['path'] = $picpath[$i]; $data['state'] = 'open'; $data['tid'] = 1; if (!$often->where($data)->find()) $often->add($data); } echo $picname[0]; } if (!empty($docname)) { for ($i = 0; $i < count($docname); $i++) { $data['userid'] = $userid['userid']; $data['text'] = $docname[$i]; $data['path'] = $docpath[$i]; $data['state'] = 'open'; $data['tid'] = 2; if (!$often->where($data)->find()) $often->add($data); } echo $docname[0]; } if (!empty($vioname)) { for ($i = 0; $i < count($vioname); $i++) { $data['userid'] = $userid['userid']; $data['text'] = $vioname[$i]; $data['path'] = $viopath[$i]; $data['state'] = 'open'; $data['tid'] = 3; if (!$often->where($data)->find()) $often->add($data); } echo $vioname[0]; } }那么到这里为止只是将文件目录上传了一次。如果用户有改变时。我们需要同步更新文件目录。笔者这里使用Fileobserver来监听文件目录的变化。

public SingleFileObserver(String path) { this(path, ALL_EVENTS); mPath = path; } public SingleFileObserver(String path, int mask) { super(path, mask); mPath = path; } @Override public void onEvent(int event, String path) { String newPath = mPath + "/" + path; RecursiveFileObserver.this.onEvent(event, newPath); } } }本来fileobserver只能对一个文件夹下面的子文件进行监听。并不能监听子目录的子文件。因此笔者这里实现了文件的递归监听。
在需要监听的地方设置如下
if (null == mFileObserver) { mFileObserver = new RecursiveFileObserver("/storage"); System.out.println("epath" + Environment.getExternalStorageDirectory().getPath()); Log.v("file", "eeee" + Environment.getExternalStorageDirectory().getPath()); mFileObserver.startWatching(); //开始监听 }这样就实现了文件目录的同步更新。
