删除地图与关键在riak

Question

我正在使用riak php客户端，并拥有数据类型映射。我想删除整个map，也就是itemid。这是我的代码

        $location = new Location($itemID, $this->itemBucket);
        $map = (new CommandBuilderFetchMap($this->riak))
        ->atLocation($location)
        ->build()
        ->execute()->getMap();
        (new CommandBuilderUpdateMap($this->riak))
        ->removeMap($itemID)
        ->atLocation($location)
        ->withContext($map->getContext())
        ->build()
        ->execute();

Answer 1

我想你混淆了包含映射对象的KV键和包含嵌套映射的映射键。

此位置将参考"http://riaknode:8098/buckets/$this->itemBucket/keys/$itemID"

    $location = new Location($itemID, $this->itemBucket);

检索上述桶/键

所包含的映射对象。

    $map = (new CommandBuilderFetchMap($this->riak))
    ->atLocation($location)
    ->build()
    ->execute()->getMap();

尝试从返回的映射对象

中删除键为$itemID的元素。

    (new CommandBuilderUpdateMap($this->riak))
    ->removeMap($itemID)
    ->atLocation($location)
    ->withContext($map->getContext())
    ->build()
    ->execute();

如果你想删除存储在bucket/key下的整个地图，你可能需要使用CommandBuilderDeleteObject
