Scrapy與Elasticsearch集成的步驟如下:
安裝Elasticsearch:首先確保已經安裝了Elasticsearch,并且Elasticsearch服務已經啟動。
安裝elasticsearch-py庫:使用pip安裝elasticsearch-py庫,這是Python與Elasticsearch交互的庫。
pip install elasticsearch
ITEM_PIPELINES = {
'scrapyelasticsearch.pipelines.ElasticsearchPipeline': 100
}
ELASTICSEARCH_SERVERS = ['localhost']
ELASTICSEARCH_INDEX = 'my_index'
ELASTICSEARCH_TYPE = 'my_type'
from elasticsearch import Elasticsearch
class ElasticsearchPipeline(object):
def __init__(self):
self.es = Elasticsearch()
def process_item(self, item, spider):
data = dict(item)
self.es.index(index=spider.settings.get('ELASTICSEARCH_INDEX'), doc_type=spider.settings.get('ELASTICSEARCH_TYPE'), body=data)
return item
通過上述步驟,您可以將Scrapy與Elasticsearch集成,實現數據的存儲和檢索。
