使用scrapy将值存储到键中

import redis

class RedisPipeline(object):
    def __init__(self, redis_host, redis_port, redis_password):
        self.redis_host = redis_host
        self.redis_port = redis_port
        self.redis_password = redis_password

    @classmethod
    def from_crawler(cls, crawler):
        return cls(
            redis_host=crawler.settings.get('REDIS_HOST'),
            redis_port=crawler.settings.get('REDIS_PORT'),
            redis_password=crawler.settings.get('REDIS_PASSWORD')
        )

    def open_spider(self, spider):
        self.redis_client = redis.Redis(
            host=self.redis_host,
            port=self.redis_port,
            password=self.redis_password
        )

    def close_spider(self, spider):
        self.redis_client.close()

    def process_item(self, item, spider):
        # 将item中的值存储到键中
        self.redis_client.set(item['key'], item['value'])
        return item

# settings.py

REDIS_HOST = 'localhost'
REDIS_PORT = 6379
REDIS_PASSWORD = 'your_password'

ITEM_PIPELINES = {
    'your_project.pipelines.RedisPipeline': 300,
}
