scrapy爬取数据后存储在本地mysql数据库中

话不多说，直接上代码

 5 # Don't forget to add your pipeline to the ITEM_PIPELINES setting

 8 class MysqlPipeline(object):

11     """

13     def __init__(self):
14         # 建立连接
15         self.conn = pymysql.connect(host='localhost',user='root',passwd='',db='spider_test',charset='utf8',port=3306)  # 有中文要存入数据库的话要加charset='utf8'
16         # 创建游标
17         self.cursor = self.conn.cursor()
18 
19     def process_item(self, item, spider):
20         # sql语句
21         insert_sql = """
22         insert into test_zxf(title,url,detail,answer) VALUES(%s,%s,%s,%s)
23         """
24         # 执行插入数据到数据库操作
25         self.cursor.execute(insert_sql, (item['title'], item['url'], item['detail'], item['answer']))
26         # 提交，不进行提交无法保存到数据库
27         self.conn.commit()
28 
29     def close_spider(self, spider):
30         # 关闭游标和连接
31         self.cursor.close()
32         self.conn.close()

注：

1、需要先在数据库中建立好数据库，表，字段

2、setting文件设置pipline

如果对你有帮助请给个赞，谢谢~
