Manual:$wgForeignFileRepos/zh

Properties required for all repos

 * class
 * The class name for the repository. May come from the core or an extension. The core repository classes are LocalRepo, ForeignDBRepo, FSRepo and ForeignAPIRepo.


 * name
 * A unique name for the repository.

For all core repos

 * url
 * Base public URL


 * thumbUrl
 * Base thumb url, if different from url/thumb


 * hashLevels
 * The number of directory levels for hash-based division of files


 * thumbScriptUrl
 * The URL for thumb.php (optional, not recommended)


 * transformVia404
 * Whether to skip media file transformation on parse and rely on a 404 handler instead.


 * initialCapital
 * Equivalent to $wgCapitalLinks, determines whether file names implicitly start with a capital letter. The current implementation may give incorrect description page links when the local $wgCapitalLinks and initialCapital are mismatched.


 * pathDisclosureProtection
 * May be 'paranoid' to remove all parameters from error messages, 'none' to leave the paths in unchanged, or 'simple' to replace paths with place holders. Default for LocalRepo is 'simple'. Note, some image thumbnailing software puts the thumbnail path into the resulting thumb's metadata, so this setting may not provide full protection.


 * descBaseUrl
 * URL of image description pages, e.g.


 * scriptDirUrl
 * URL of the MediaWiki installation, equivalent to, e.g.


 * articleUrl
 * Equivalent to, e.g.


 * fetchDescription
 * Fetch the text of the remote file description page. Equivalent to $wgFetchCommonsDescriptions.


 * descriptionCacheExpiry
 * If set to 0, no caching will be used. Set to 1 or more (seconds) to define how long the local cache of description pages will last. Must set fetchDescription to true to use.

ForeignAPIRepo类

 * apibase
 * The base URL for the remote repository's API (eg: ). Only used for ForeignAPIRepo.


 * apiThumbCacheExpiry
 * How long to cache thumbs locally for. Not setting this or setting to 0 disables local thumb caching

ForeignDBRepo类

 * directory
 * A path to MediaWiki's media directory local to the server, such as.


 * dbType, dbServer, dbUser, dbPassword, dbName, dbFlags
 * equivalent to the corresponding member of $wgDBservers


 * tablePrefix
 * Table prefix, the foreign wiki's $wgDBprefix


 * hasSharedCache
 * True if the wiki's shared cache is accessible via the local $wgMemc


 * favicon
 * A favicon for the remote repository

默认值（位于Setup.php中的代码）

ForeignDBViaLBRepo class

 * wiki
 * wiki-db-name used in

Directory permissions
You'll need rw on  and   for whatever user php runs as.

Using files from Wikimedia Commons : ForeignAPIRepo

 * Since 1.16.0 there is a more convenient shorthand to use Commons as a foreign repository: .

You can set your wiki to use media from Wikimedia Commons (or from any other MediaWiki-powered site, see below) directly. However, please beware any legal implications.

使用前您需要先：


 * MediaWiki 1.13 或之后版本
 * PHP with JSON support (for the  function). JSON is enabled by default since PHP 5.2.0, you'll need the PECL extension for older versions. Since MediaWiki 1.16, this is no longer necessary; v. 1.16 will use custom (and slower) code if JSON is not available.
 * The remote wiki must also use MediaWiki 1.13 or later; otherwise its  returns   and file requests fail silently (i.e. the requested files are just treated as non-existent).

The code below enables media files from Wikimedia Commons on your site. You should place it in you "LocalSettings.php" file:

To pull images from another Wikimedia project, set apibase to this wiki's "api.php" file like e.g.  https://en.wikipedia.org/w/api.php . 例如：

To embed an image in your installation, simply use  .

You may need to configure the $wgMainCacheType as well. Default it is set to CACHE_NONE, meaning it will load the image from the remote host on each page load. Similarly, you need to set apiThumbCacheExpiry to zero if you prefer to use the foreign thumbnails.

从数据库中使用文件您可以使用：ForeignDBRepo、ForeignDBViaLBRepo
The ForeignDBRepo class is very useful for creating wiki families. In a wiki family, each wiki will have its own database or table prefix. Using this class, you can make a family member aware of the tables of another family member. Access through ForeignDBRepo is faster than through ForeignAPIRepo. This code should be deployed to LocalSettings.php.

Alternatively, if you have $wgLBFactoryConf set up for multiple wikis, you can use 'class' => 'ForeignDBViaLBRepo':

This needs not all the db* parameters as in.

从本地文件夹使用文件：FSRepo
You can set your wiki to use media from a single folder. This is just a demonstration feature at present, and will probably be too slow for busy wikis or slow servers due to the lack of caching. This code should be deployed to LocalSettings.php.

The below code enabled media files from it:
