php - 在 php 中实现 Dropbox API 的问题

Question

我正在尝试创建一个页面，该页面将以可呈现的沙盒方式显示保管箱文件夹的内容，并允许浏览用户（登录到我一直在开发的网站）能够单击并下载各种文件文件夹内。这是我正在使用的代码：这是文件 bootstrap.php...

    <?php
// Prevent calling this script directly
if ($_SERVER["SCRIPT_FILENAME"] == __FILE__) {
    exit("Access denied!");
}

// app settings
$config = array();
$config["dropbox"]["app_key"] = "***";
$config["dropbox"]["app_secret"] = "***";
// ACCESS_TYPE should be "dropbox" or "app_folder"
$config["dropbox"]["access_type"] = "dropbox";

$config["app"]["root"] = ((!empty($_SERVER["HTTPS"])) ? "https" : "http") . "://" . $_SERVER["HTTP_HOST"] . "/";
$config["app"]["datadir"] = dirname(__FILE__) . "/data";
$config["app"]["authfile"] = $config["app"]["datadir"] . "/auth.php";

// turn on error reporting for development
error_reporting(E_ALL|E_STRICT);
ini_set("display_errors", true);

// environment check
if (!is_dir($config["app"]["datadir"]) || !is_writable($config["app"]["datadir"])) {
    exit("The data directory is not writeable!");
}
if (file_exists($config["app"]["authfile"]) && !is_writable($config["app"]["authfile"])) {
    exit("The auth storage file is not writeable!");
}

// Load libraries and start a new session
require_once "lib/dropbox/rest.php";
require_once "lib/dropbox/session.php";
require_once "lib/dropbox/client.php";

if(!isset($_SESSION)){session_start();}

// Search for a previously obtained access token
$access_token = null;
if (file_exists($config["app"]["authfile"])) {
    include_once $config["app"]["authfile"];
}

这是文件authorize.php...

<?php
require_once "bootstrap.php";

if (isset($access_token)) {
    header("Location: ./");
    exit;
}

try {
    // Start a new Dropbox session
    $session = new DropboxSession(
        $config["dropbox"]["app_key"],
        $config["dropbox"]["app_secret"],
        $config["dropbox"]["access_type"]
    );

    // The user is redirected here by Dropbox after the authorization screen
    if (!empty($_GET["oauth_token"]) && !empty($_GET["uid"])) {
        $uid = $_GET["uid"];
        $token = array(
            "oauth_token" => $_GET["oauth_token"],
            "oauth_token_secret" => ""
        );

        if (!empty($_SESSION["request_token"])) {
            $token["oauth_token_secret"] = $_SESSION["request_token"]["oauth_token_secret"];
        }

        /**
         * The access token is all you'll need for all future API requests on
         * behalf of this user, so you should store it away for safe-keeping 
         * (even though we don't for this article). By storing the access
         * token, you won't need to go through the authorization process again
         * unless the user revokes access via the Dropbox website.
         */
        if ($access_token = $session->obtainAccessToken($token)) {
            parse_str($access_token, $token);
            $access_token = $token;
            unset($token);

            // The output ov var_export is similar to:
            // array("oauth_token_secret" => "aaaa", "oauth_token" => "bbbb", "uid" => "123456")
            $data = '<?php $access_token = ' . var_export($access_token, true) . ";";
            if (file_put_contents($config["app"]["authfile"], $data) === false) {
                throw new Exception("Unable save access token");
            }

            // Authorized, redirect to index
            //header("Location: index_inside.php");
            echo "Authorized, <a href=\"list.php\">click here</a> to redirect!";
            exit;
        }
        // The access token should be stored somewhere to be reused until
        // it expires or is revoked by the user
    }
    else {
        // We must start a new authorization cycle
        if ($request_token = $session->obtainRequestToken()) {
            // The request token must be subdivided in the two components 
            // oauth_token_secret and oauth_token and kept in the session
            // because is needed in the next step
            parse_str($request_token, $token);
            $_SESSION["request_token"] = $token;

            $url = $session->buildAuthorizeURL(
                $token, 
                $config["app"]["root"] . basename($_SERVER["SCRIPT_NAME"]),
                "en-US");

            // Display or redirect to auth URL
            echo '<p>Please visit <a href="' . $url . '">Dropbox</a> and authorize this application.</p>';
            exit;
        }
        else {
            throw new Exception("Unable to get request token");
        }
    }
}
catch (Exception $e) {
    echo $e->getMessage();
}

这是文件 list_inside.php ...最终包含在其中以显示文件夹列表（最好是带有下载链接的文件）...

<?php
require_once "bootstrap.php";

if (!isset($access_token)) {
    header("Location: authorize.php");
    exit;
}

try {
    // Start a new Dropbox session
    // The access token should be defined
    // The session should verify if the token is valid and throw an exception
    $session = new DropboxSession(
        $config["dropbox"]["app_key"], 
        $config["dropbox"]["app_secret"], 
        $config["dropbox"]["access_type"], 
        $access_token
    );
    $client = new DropboxClient($session);

    $path = (!empty($_GET["path"])) ? $_GET["path"] : "/Apps/Tools/";

    // List contents of home directory
    if ($home = $client->metadata($path)) {
        echo "<p>Metadata content for <code>" . $path . "</code></p>";
        echo "<pre>" . print_r($home, true) . "</pre>";
    }
}
catch (Exception $e) {
    echo "<strong>ERROR (" . $e->getCode() . ")</strong>: " . $e->getMessage();
    if ($e->getCode() == 401) {
        // Remove auth file
        unlink($config["app"]["authfile"]);
        // Re auth
        echo '<p><a href="authorize.php">Click Here to re-authenticate</a></p>';
    }
}

这是使用 metadata() 的上述代码的输出：

我为断断续续的代码道歉，我在这方面不是很熟练，但是，我的朋友在网站上需要帮助，我跳进去帮助 Dropbox 工作。

问题是......它显示了有关文件夹的一系列信息，但没有可见的文件带有下载链接。

添加了信息..这是我尝试的另一个页面代码：（我在 php 正下方列出了此的输出）

<?php
require_once "bootstrap.php";

if (!isset($access_token)) {
    header("Location: authorize.php");
    exit;
}

try {
    // Start a new Dropbox session
    // The access token should exist
    // The session should verify if the token is valid and throw an exception
    $session = new DropboxSession(
        $config["dropbox"]["app_key"], 
        $config["dropbox"]["app_secret"], 
        $config["dropbox"]["access_type"], 
        $access_token
    );

    $client = new DropboxClient($session);
    $path = (!empty($_GET["path"])) ? $_GET["path"] : "/webs.pdf";
    $dest = $config["app"]["datadir"] . "/" . basename($path);

    // Download a file
    if ($file = $client->getFile($path, $dest)) {

        if (!empty($dest)) {
            unset($file["data"]);
            echo "<p>File saved to: <code>" . $dest . "</code></p>";
            echo "<pre>" . print_r($file, true) . "</pre>";
        }
        else {
            header("Content-type: " . $file["mime"]);
            echo $file["data"];
            exit;
        }
    }
}
catch (Exception $e) {
    echo "<strong>ERROR (" . $e->getCode() . ")</strong>: " . $e->getMessage();
    if ($e->getCode() == 401) {
        // Remove auth file
        unlink($config["app"]["authfile"]);
        // Re auth
        echo '<p><a href="authorize.php">Click Here to re-authenticate</a></p>';
    }
}

这是上述代码的输出：

文件保存到：/home/thisisyo/public_html/data/webs.pdf 数组（[name] => /home/thisisyo/public_html/data/webs.pdf [mime] => application/pdf [meta] => stdClass Object ( [revision] => 35075 [rev] => 890304ef29f8 [thumb_exists] => [bytes] => 703289 [modified] => 2013 年 6 月 20 日星期四 23:39:10 +0000 [client_mtime] => 2 月 20 日星期三2013 19:19:42 +0000 [path] => /webs.pdf [is_dir] => [icon] => page_white_acrobat [root] => dropbox [mime_type] => application/pdf [size] => 686.8 KB）

)

此外，这是在 client.php 中定义的类：

public function metadata($path, $list = true, $fileLimit = 10000, $hash = null, $revision = null, $includeDeleted = false) {
    // Prepare argument list
    $args = array(
        "file_limit" => $fileLimit,
        "hash" => $hash,
        "list" => (int) $list,
        "include_deleted" => (int) $includeDeleted,
        "rev" => $revision
    );

    // Prepend the right access string to the desired path
    if ("dropbox" == $this->accessType) {
        $path = "dropbox" . $path;
    }
    else {
        $path = "sandbox" . $path;
    }

    // Execute
    $response = $this->Session->fetch("GET", $this->dropboxAPIURL, "/metadata/" . $path, $args);
    return $response["body"];
}

这是 getFile() 类定义...

公共函数 getFile($path, $outFile = null, $revision = null) {

$args = array();
if (!empty($revision)) {
    $args["rev"] = $revision;
}

// Prepend the right access string to the desired path
if ("dropbox" == $this->accessType) {
    $path = "dropbox" . $path;
}
else {
    $path = "sandbox" . $path;
}

// Get the raw response body
$response = $this->Session->fetch("GET", $this->dropboxContentAPIURL, "/files/" . $path, $args, true);

if ($outFile != null) {
    if (file_put_contents($outFile, $response["body"]) === false) {
        throw new Exception("Unable to write file '$outfile'");
    }
}

return array(
    "name" => ($outFile) ? $outFile : basename($path),
    "mime" => $response["headers"]["content-type"],
    "meta" => json_decode($response["headers"]["x-dropbox-metadata"]),
    "data" => $response["body"]
);

}

you just need to call a function to download the file .

require_once 'dropbox/DropboxClient.php';
$dropbox = new DropboxClient(array(
        'app_key' => DROPBX_API_KEY, 
        'app_secret' => DROPBX_API_SECRET,
        'app_full_access' => TRUE,
),'en');
$fileMetadata = $dropbox->DownloadFile($value->path,'download/'.$file);

check this if it can help you

对于您的 list_inside.php 页面，您需要做的就是遍历您的$client->metadata()数组并打印 HTML。这是该页面的示例：

<?php

require_once "bootstrap.php";

if (!isset($access_token)) {
    header("Location: authorize.php");
    exit;
}

try {
    // Start a new Dropbox session
    // The access token should be defined
    // The session should verify if the token is valid and throw an exception
    $session = new DropboxSession(
        $config["dropbox"]["app_key"], 
        $config["dropbox"]["app_secret"], 
        $config["dropbox"]["access_type"], 
        $access_token
    );
    $client = new DropboxClient($session);

    $path = (!empty($_GET["path"])) ? $_GET["path"] : "/Apps/Tools/";

    // List contents of home directory
    if ($home = $client->metadata($path)) {
        echo <<<EOF
        <h1>Index of $index</h1>

        <table>
            <thead>
                <tr>
                    <th>Name</th>
                    <th>Last Modified</th>
                    <th>Size</th>
                    <th>Type</th>
                </tr>
            </thead>
            <tbody>
        EOF;

        foreach($home as $list) {
            $link = ($list[is_dir] == 1 ? "list_inside" : "download").".php?path=".$list[path];
            $file = explode("/", $list[path]);
            $path = $file[count($file)-1];
            $size = ($list[bytes] == 0 ? "-" : $list[size]);

            echo <<<EOF
                <tr>
                    <td><a href="$link">$path</a></td>
                    <td>$list[modified]</td>
                    <td>$size</td>
                    <td>$list[type]</td>
                </tr>
            EOF;
        }

        echo <<<EOF
            </tbody>
        </table>
        EOF;
    }
} catch (Exception $e) {
    echo "<strong>ERROR (" . $e->getCode() . ")</strong>: " . $e->getMessage();
    if ($e->getCode() == 401) {
        // Remove auth file
        unlink($config["app"]["authfile"]);
        // Re auth
        echo '<p><a href="authorize.php">Click Here to re-authenticate</a></p>';
    }
}

?>
