Wiki pages can be exported in a special XML format to upload into another MediaWiki.[1] See Справка:Экспорт for more details.
Параметры сообщений
Below is the list of available parameters for Special:Export as of version 1.16. Не все из них доступны через специальный интерфейс:Export UI.
| Параметр | Тип переменной | Description |
|---|---|---|
action
|
строка | Unused; set to "submit" in the export form. |
| Выбор страниц | ||
/ (no parameter)
|
Selects up to one page, e.g. Special:Export/Sandbox. | |
pages
|
? | A list of page titles, separated by linefeed (%0A) characters. Maximum of 35 pages. |
addcat/название категории
|
строка ? | These were added later. addcat returns all members of the category catname added to it. If $wgExportFromNamespaces is enabled, addns and nsindex do the same, but with namespaces and their numerical indexes. A maximum of 5000 page titles will be returned.
For example, the following is for all pages in en:Category:Books: https://en.wikipedia.org/w/index.php?title=Special:Export&addcat&catname=Books&pages=XXXX |
addns/индекс namespace
| ||
| Сортировка | ||
dir[2]
|
строка | Should be set to "desc" to retrieve revisions in reverse chronological order.
The default, with this parameter omitted, is to retrieve revisions in ascending order of timestamp (oldest to newest). |
| Limiting Results | ||
offset[2]
|
? | The timestamp at which to start, which is non-inclusive. The timestamp may be in several formats, including the 14-character format usually used by MediaWiki, and an ISO 8601 format like the one that is output by the XML dumps. |
limit[2]
|
Целое число | The maximum number of revisions to return. If you request more than a site-specific maximum (defined in $wgExportMaxHistory: 1000 on Wikimedia projects at present), it will be reduced to this number.
This limit is cumulative across all the pages specified in the pages parameter. For example, if you request a limit of 100, for two pages with 70 revisions each, you will get 70 from one and 30 from the other.[3] |
curonly
|
Логическое | Включить только текущую пересмотр (по умолчанию для GET запросов ). |
history
|
? | Include the full history, overriding dir, limit, and offset.
This is not working for all say https://en.wikipedia.org/w/index.php?title=Special:Export&pages=US_Open_(tennis)&history=1&action=submit works fine and gives all revisions but https://en.wikipedia.org/w/index.php?title=Special:Export&pages=India&history=1&action=submit doesn't. |
| Дополнительные | ||
templates
|
? | Включает любые переведенные шаблоны на любой странице, перечисленной для экспорта. |
listauthors
|
Логическое | Включите в список всех участников и ID идентификаторы пользователей для каждой страницы. Functionality is disabled by default; can be enabled by changing $wgExportAllowListContributors. |
pagelink-depth
|
Integer | Includes any linked pages to the depth specified. Limited to $wgExportMaxLinkDepth (defaults to 0, disabling the feature), or 5 if user does not have permission to change limits. |
wpDownload
|
? | Запись в виде файла, названная с текущей часовой датой. Implemented through content-disposition:attachment HTTP header.
|
URL ссылки не работают
The dir, offset and limit parameters only work for POST requests.
GET requests through a URL are ignored.
Когда вы используете URL-адрес как в браузере, вы подаете через GET. В скрипте ruby вы используете POST
As an example, the following parameter request does not work, it returns all revisions of a page despite the parameter limit=5.
https://en.wikipedia.org/w/index.php?title=Special:Export&pages=XXXX&offset=1&limit=5&action=submit
Извлечение прежних 5 релизов
A POST request is generated by cURL when passing -d "".
The following retrieves the earliest 5 revisions from the English Wikipedia main page and its talk page:
curl -d "" 'https://en.wikipedia.org/w/index.php?title=Special:Export&pages=Main_Page%0ATalk:Main_Page&offset=1&limit=5&action=submit'
And here are the next 5 revisions of the main page only:
curl -d "" 'https://en.wikipedia.org/w/index.php?title=Special:Export&pages=Main_Page&offset=2002-01-27T20:25:56Z&limit=5&action=submit'
Here the timestamp from the last revision of the previous query is copied into the offset field of the URL. Because the offset field is non-inclusive, that 5th revision is not displayed again, and instead we get revisions 6-10.[4]
POST команда для загрузки
A more explicit example, especially if you also want to save the darn thing, would be
curl -d "&pages=Main_Page&offset=1&action=submit" https://en.wikipedia.org/w/index.php?title=Special:Export -o "somefilename.xml"
The URL root needs to follow the MediaWiki parameters... also, note the fact that you need to add the curl parameters at the end for saving the file as something. В противном случае он просто прокручивается по экрану и ничего не будет сохранено , будет белый экран. В настоящее время, похоже, серверы Википедии находятся на техническом обслуживании, следовательно, приведенный выше метод показывает ошибку и не предоставляет xml.
If you instead have the list of titles in a file, say title-list, you must pass the list as a parameter to curl and encode the linefeeds correctly (for some reason, --data-urlencode and @ do not work):
curl -d "&action=submit&pages=$(cat title-list | hexdump -v -e '/1 "%02x"' | sed 's/\(..\)/%\1/g' )" https://en.wikipedia.org/w/index.php?title=Special:Export -o "somefilename.xml"
Если вы хотите сохранить пропускную способность, добавьте следующие аргументы:
--compressed -H 'Accept-Encoding: gzip,deflate'
Остановка экспорта вашей MediaWiki
Пожалуйста, имейте в виду, что затруднение для ваших пользователей создания резервных копий своей работы , может отбить у них охоту вносить свой вклад в вашу вики.
If $wgExportAllowHistory is set to false in LocalSettings.php, only the current version can be exported, not the full history.
По умолчанию при запросах GET возвращается только текущая (последней) версия каждой страницы.
If the $wgExportAllowHistory parameter is true in LocalSettings.php, and the "Include only the current revision, not the full history" is unchecked, then all versions of each page are returned.
To disable export completely, you need to set a callback-function in your LocalSettings.php:
function removeExportSpecial(&$aSpecialPages)
{
unset($aSpecialPages['Export']);
return true;
}
$wgHooks['SpecialPage_initList'][] = 'removeExportSpecial';
If you want to define a permission for export, put the following in your LocalSettings.php:
// Override SpecialExport, which is work for MW1.35
// the parameters of __construct() are changed in later versions
class SpecialExport2 extends SpecialExport {
public function __construct() {
parent::__construct();
$this->mRestriction = 'export';
}
public function execute( $par ) {
$this->checkPermissions();
parent::execute( $par );
}
}
function adjustExportSpecial(&$aSpecialPages)
{
$aSpecialPages['Export'] = SpecialExport2::class;
return true;
}
$wgHooks['SpecialPage_initList'][] = 'adjustExportSpecial';
$wgGroupPermissions['sysop']['export'] = true; // Add export permission to sysop only
Имейте в виду, что экспорт все еще возможен, если у вас включен API.
Примечания
- ↑ If this function is enabled on the destination wiki, and the user is a sysop there. The export can be used for analyzing the content. See also Syndication feeds for exporting other information but pages and Help:Import on importing pages.
- ↑ 2.0 2.1 2.2 These parameters are ignored if either
curonlyorhistoryare supplied, or if passed via a GET request (e.g., a browser address bar). See URL parameter requests do not work for more information. - ↑ The order is by page_id, pages with lower page_id get more revisions. The reason for this is that Special:Export only ever does one database query per HTTP request. If you want to request all the history of several pages with many revisions each, you have to do it one page at a time.
- ↑ This parameter convention is very similar to the one for UI history pages.
