事件源内容存储库中节点的日志

安装

通过 Composer 安装

composer require wwwision/node-event-log

之后，请确保执行 doctrine 迁移

./flow doctrine:migrate

EventLogProjector 已注册为 "ContentRepository" 事件存储的事件监听器，并且每当发布新事件时都会更新。

要使用已发布的事件初始化投影器，可以使用 projection:replay 命令

./flow projection:replay eventlog

用法

过滤

事件日志可以根据多个属性进行过滤，包括

• 受影响的 节点（递归或不递归）
• 内容流（或 工作空间名称）
• 发起用户
• 维度空间点

示例

$recursively = true;
$filter = EventLogFilter::create()
    ->forNode(NodeAggregateIdentifier::fromString('some-node-id'), $recursively)
    ->inContentStream(ContentStreamIdentifier::fromString('some-content-stream-id'))
    ->forInitiatingUser(UserIdentifier::fromString('some-user-id'))
    ->skipInheritedEvents();

渲染前 5 种事件类型

$result = $this->eventLog->filter(EventLogFilter::create());
echo 'Total number of results: ' . $result->count() . PHP_EOL;
/** @var NodeEvent $event */
foreach ($result->first(5)->toNodeArray() as $event) {
    echo $event->eventType() . PHP_EOL;
}

输出（取决于实际事件）

Total number of results: 123
Neos.EventSourcedContentRepository:RootNodeAggregateWithNodeWasCreated
Neos.EventSourcedContentRepository:NodeAggregateWithNodeWasCreated
Neos.EventSourcedContentRepository:NodeAggregateWithNodeWasCreated
Neos.EventSourcedContentRepository:NodeAggregateWithNodeWasCreated
Neos.EventSourcedContentRepository:NodePropertiesWereSet

按降序分页显示结果

$result = $this->eventLog->filter(EventLogFilter::create())->reversed();
$after = null;
do {
    $page = $result->first(3, $after);
    foreach ($page as $edge) {
        /** @var NodeEvent $event */
        $event = $edge->node();
        echo $event->id() . PHP_EOL;
    }
    echo '----' . PHP_EOL;
    $after = $page->pageInfo()->endCursor();
} while ($page->pageInfo()->hasNextPage());

输出（取决于实际事件）

自定义事件渲染器

$result = $this->eventLog->filter(EventLogFilter::create())
    ->withNodeConverter(fn(array $event) => $event['id']);
echo implode(',', $result->first(10)->toNodeArray());

输出

1,2,3,4,5,6,7,8,9,10

命令行界面

此包包含一个 nodeeventlog:show 命令，允许在命令行中过滤和渲染事件日志

./flow help nodeeventlog:show

Output activities with the specified filters applied

COMMAND:
  wwwision.nodeeventlog:nodeeventlog:show

USAGE:
  ./flow nodeeventlog:show [<options>]

OPTIONS:
  --node               id of the node to fetch activities for
                       (NodeAggregateIdentifier)
  --content-stream     id of the content stream to filter for
                       (ContentStreamIdentifier)
  --workspace          name of the workspace to filter for (WorkspaceName)
  --user               id of the initiating user to filter for (UserIdentifier)
  --dimension          JSON string representing the dimensions space point to
                       filter for (DimensionSpacePoint)
  --recursively        If set activities for all child nodes will be fetched as
                       well (recursively) – this is only evaluated if
                       "--node" is specified, too
  --skip-inherited-events If set only explicit events are considered. Otherwise
                       "inherited" events, e.g. for disabled/removed/moved
                       nodes are included in the result
  --reverse            If set the order of the event log is reversed to show
                       the events in the order they occured
  --first              How many events to display at once (default: 10)
  --after              Only fetch events after the specified cursor (only
                       applicable in conjunction with --first)
  --last               How many events to display at once (default: 10)
  --before             Only fetch events before the specified cursor (only
                       applicable in conjunction with --first)
