Question

我想创建一个PHP脚本来将文件从我网站上的特定目录备份到我的Dropbox帐户。

我试图搜索示例以及如何解决它但我只找到备份数据库或购买现成解决方案的代码。

这是我试过的代码

<?php
  $passw = "jason"; //change this to a password of your choice.
  if ($_POST) {
    require 'DropboxUploader.php';


    try {
        // Rename uploaded file to reflect original name
        if ($_FILES['file']['error'] !== UPLOAD_ERR_OK)
            throw new Exception('File was not successfully uploaded from your computer.');

        $tmpDir = uniqid('/tmpCapes/');
        if (!mkdir($tmpDir))
            throw new Exception('Cannot create temporary directory!');

        if ($_FILES['file']['name'] === "")
            throw new Exception('File name not supplied by the browser.');

        $tmpFile = $tmpDir.'/'.str_replace("/\0", '_', $_FILES['file']['name']);
        if (!move_uploaded_file($_FILES['file']['tmp_name'], $tmpFile))
            throw new Exception('Cannot rename uploaded file!');

    if ($_POST['txtPassword'] != $passw)
            throw new Exception('Wrong Password');

        // Upload
    $uploader = new DropboxUploader('user@example.com', 'password');// enter dropbox credentials
        $uploader->upload($tmpFile, $_POST['dest']);

        echo '<span style="color: green;font-weight:bold;margin-left:393px;">File successfully uploaded to my Dropbox!</span>';
    } catch(Exception $e) {
        echo '<span style="color: red;font-weight:bold;margin-left:393px;">Error: ' . htmlspecialchars($e->getMessage()) . '</span>';
    }

    // Clean up
    if (isset($tmpFile) && file_exists($tmpFile))
        unlink($tmpFile);

    if (isset($tmpDir) && file_exists($tmpDir))
        rmdir($tmpDir);
}
?>

但不是通过我的网站将图像从我的PC上传到Dropbox。我想修改上面的代码，将我网站上特定目录中的文件复制到Dropbox。

您需要递归代码。

编写一个以dir为参数的函数。

让它遍历dir查看每个文件。对于每个文件，它会检查它是否为dir，如果不是，则复制它。

如果它是一个目录，则该函数会自行调用。

e.g。

// your code
require 'DropboxUploader.php';

$dirtocopy = './example_directory/';
$dropboxdir = 'backupdir/';
$uploader = new DropboxUploader('sample-email@gmail.com', 'password');// enter dropbox credentials

$errors = array(); // to store errors.


// function definition
function copyDirRecursive($dir) {
  global $uploader; // makes the "$uploader" below the one from outside the function
  if(is_dir($dir)) { // added if/else to check if is dir, and create handle for while loop
    $handle = opendir($dir); 
    if($handle === false) { // add if statements like this wherever you want to check for an error
      $errors[] = $php_errormsg; // http://php.net/manual/en/reserved.variables.phperrormsg.php
    }
  } else {
    return false;
  }
  while(false !== ($file = readdir($handle))) { // changed foreach to while loop
    if(!isdir($file)) {
      // copy the file
      // cp $dir . '/' . $file to $dropbox . '/' . $dir . '/' . $file; // pseudocode
      // below is actual code that hopefully will work
      $uploader->upload($dir.$file,$dropboxdir.$file);
    } else {
      if(!is_link($file)) { // probably best not to follow symlinks, so we check that with is_link()
        copyDirRecursive($dir . '/' . $file); // recursion time
      }
    }

  }
}

// CALL THE FUNCTION
copyDirRecursive($dirtocopy); // you have to call a function for it to do anything

print_r($errors); // use this or var_dump($errors) to see what errors came up

基于代码，您需要的内容符合

require 'DropboxUploader.php';

$dirtocopy = './example_directory/';
$dropboxdir = '/backupdir/';
$uploader = new DropboxUploader('email@gmail.com', 'Password');// enter dropbox credentials

if ($handle = opendir($dirtocopy)) {
    while (false !== ($entry = readdir($handle))) {
        if ($entry != "." && $entry != "..") {

            $uploader->upload($dirtocopy.$entry, $dropboxdir.$entry);

        }
    }
    closedir($handle);
}

我对Dropbox目录代码并不是100％肯定，因为我刚刚将其从您的示例中删除，您可能希望删除/中的第一个$dropboxdir。但我相信你能搞清楚。

作为参考，循环目录的代码是来自http://php.net/manual/en/function.readdir.php

的示例＃2

用于递归目录复制

require 'DropboxUploader.php';

function uploaddirtodropbox($dirtocopy, $dropboxdir, $uploader){
    if ($handle = opendir($dirtocopy)) {
        while (false !== ($entry = readdir($handle))) {
            if ($entry != "." && $entry != "..") {

                if(is_dir($entry)){
                    uploaddirtodropbox($dirtocopy.$entry.'/', $dropboxdir.$entry.'/', $uploader);
                } else {
                    $uploader->upload($dirtocopy.$entry, $dropboxdir.$entry);
                }

            }
        }
        closedir($handle);
    }
}

$dirtocopy = './example_directory/';
$dropboxdir = '/backupdir/';
$uploader = new DropboxUploader('email@gmail.com', 'Password');// enter dropbox credentials

uploaddirtodropbox($dirtocopy, $dropboxdir, $uploader);

在您使用此https://github.com/jakajancar/DropboxUploader/请求帮助的问题中，我已经为您提供了代码，但是如果您阅读了github页面，那么

它的开发是在Dropbox发布其API之前开始的工作，它刮擦他们的网站。所以你可以并且可能应该使用他们的API现在。

因此，寻找替代方案可能是个好主意。
