使用PHP访问WebDAV

Question

我有以下代码：

<?php
include 'vendor/autoload.php';
use Sabre\DAV\Client;

$settings = array(
    'baseUri' => "https://example.com/remote.php/dav/files/foo/",
    'userName' => "foo",
    'password' => "secret"
);

$client = new Client($settings);
$response = $client->request('GET');
var_dump($response);

这里是输出：

array(3) {
  ["body"]=>
  string(114) "This is the WebDAV interface. It can only be accessed by WebDAV clients such as the Nextcloud desktop sync client."
  ["statusCode"]=>

    array(1) {
      [0]=>
      string(24) "text/html; charset=UTF-8"
    }
  }
}

如果我这样做

<?php
include 'vendor/autoload.php';
use Sabre\DAV\Client;

$settings = array(
    'baseUri' => "https://example.com/remote.php/dav/files/foo/",
    'userName' => "foo",
    'password' => "secret"
);

$client = new Client($settings);
$folder_content = $client->propFind('/', array(
    '{DAV:}getlastmodified',
    '{DAV:}getcontenttype',
),1);
var_dump($folder_content);

输出：

致命错误：未捕获的Sabre \ HTTP \ ClientHttpException：方法不正确允许进入/var/www/html/lib/DAV/Client.php:235堆栈跟踪：＃0 /var/www/html/index.php(23）：Sabre \ DAV \ Client-> propFind（'https://example ...'，Array，1）＃1 {main}在/var/www/html/lib/DAV/Client.php中抛出第235行

我正在使用以下库在webDAV中进行访问：https://github.com/sabre-io/dav

在服务器端，我安装了nextcloud实例（v 17）。

基于此帖子https://medium.com/@cetteup/how-to-access-nextcloud-using-webdav-and-php-2c00a04e35b9

还有其他方法可以通过PHP中的webDAV列出文件夹的内容吗？

编辑：

<?php
include 'vendor/autoload.php';
$settings = array(
    'baseUri' => "https://example.com/remote.php/dav/files/foo/",
    'userName' => "foo",
    'password' => "secret"
);
$client = new Sabre\DAV\Client($settings);
$features = $client->options();
var_dump($features);

输出：

array(3) { 
    [0]=> string(1) "1" 
    [1]=> string(1) "3" 
    [2]=> string(14) "extended-mkcol" 
}

Answer 1

当您呼叫$client->propFind('/', ....)时，实际的有效URL将是：

https://example.com/

不是

https://example.com/remote.php/dav/files/foo/

要获取相对于基本uri的文件夹的内容，您只需要删除斜线

$folder_content = $client->propFind('', array(
    '{DAV:}getlastmodified',
    '{DAV:}getcontenttype',
),1);
