python - 尝试连接外部 MySQL 数据库时卡在连接器上。连接

Question

我正在尝试用树莓派在我的电脑上建立的 wamp 数据库上插入一行。两个设备都连接到同一个路由器，我已经为 RPi 设置了用户权限，但是当我尝试连接到数据库时，代码粘在连接器上。连接功能并且没有捕获任何异常。这是使用的代码:

from mysql import connector

print('0')
try:
    con = connector.Connect(user='own_pi',password='password',database='tempbase',host='192.168.0.104', port=3306)
except connector.Error as e:
    print("Error code:", e.errno)        # error number
    print("SQLSTATE value:", e.sqlstate) # SQLSTATE value
    print("Error message:", e.msg)       # error message
    print("Error:", e)                   # errno, sqlstate, msg values
    s = str(e)
    print("Error:", s)                   # errno, sqlstate, msg values

print('1')
cur = con.cursor()
print('2')
cur.execute("INSERT INTO `sensor_readings` (`uid`, `local_id`, `type`, `date`, `reading`) VALUES ('7', '4', 'temperature', '2018-06-04', '24.4');")
print('3')
con.commit()
print('4')
con.close()
print('5')

这条 print('1') 行永远不会被调用，并且进程永远保持事件状态。

您知道什么可能会引发这种行为以及如何解决它吗？

尝试使用:

from mysql import connector

print('0')
try:
    con = connector.Connect(user='own_pi',password='password',database='tempbase',host='192.168.0.104', port=3306)
    print('1')

    cur = con.cursor()
    print('2')
    cur.execute("INSERT INTO `sensor_readings` (`uid`, `local_id`, `type`, `date`, `reading`) VALUES ('7', '4', 'temperature', '2018-06-04', '24.4');")
    print('3')
    con.commit()
    print('4')
    con.close()
    print('5')

except connector.Error as e:
    print("Error code:", e.errno)        # error number
    print("SQLSTATE value:", e.sqlstate) # SQLSTATE value
    print("Error message:", e.msg)       # error message
    print("Error:", e)                   # errno, sqlstate, msg values
    s = str(e)
    print("Error:", s)                   # errno, sqlstate, msg values
