我想通过在python脚本中使用websocket将raspberry pi中的值放入笔记本电脑上的sql数据库。
# starting import MySQLdb
import MySQLdb
# Open database connection
db = MySQLdb.connect("localhost","root","","cms",autocommit=True)
# prepare a cursor object using cursor() method
cursor = db.cursor()
from websocket import create_connection
ws = create_connection("ws://192.168.0.53:8080/websocket")
while True:
result = ws.recv()
print(result)
spl = result.split(' ',1)
boom_id2 = str(spl[0])
boom_data = str(spl[1])
sql = """INSERT INTO datain(boom_id2,boom_data)
# VALUES ('""" + boom_id2 +"""', '""" + boom_data +"""')"""
cursor.execute(sql)
db.close()
ws.close()
它返回一个错误:
Traceback (most recent call last):

您的sql查询中有一个错误,应该是这样的
请尝试打印此sql查询并在本地服务器上运行,以检查查询是否正确
