您可以使用Python中的MySQL Replication库来监听MySQL数据库。该库提供了一个ReplicationConnection类,该类在MySQL服务器上创建一个基于binlog的连接,并提供了一些有用的方法来处理binlog事件。以下是一个示例代码:
```python
from mysql_replication import BinLogStreamReader
config = {
"host": "localhost",
"port": 3306,
"user": "root",
"passwd": "password"
}
stream = BinLogStreamReader(
connection_settings=config,
server_id=100,
blocking=True,
only_events=['tablemap', 'writerows', 'updaterows', 'deleterows']
)
for binlogevent in stream:
if binlogevent.event_type == "tablemap":
table_name = binlogevent.table
print("Table Name: ", table_name)
elif binlogevent.event_type == "writerows":
for row in binlogevent.rows:
print("Insert Row: ", row)
elif binlogevent.event_type == "updaterows":
for row in binlogevent.rows:
print("Update Row: ", row)
elif binlogevent.event_type == "deleterows":
for row in binlogevent.rows:
print("Delete Row: ", row)
stream.close()
```
此代码连接到本地MySQL服务器的root用户,使用密码password,并监听所有表的插入,更新和删除事件。您可以更改配置以适应您的环境,并使用适当的only_events参数来监听特定的事件类型。
