无法使用 python 连接到 mysql db - 握手错误

Question

我正在尝试使用我的 python 脚本（在本地运行）连接到 mysql 数据库（托管在媒体神庙上），但在运行时收到错误。

错误是：

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/mysql/connector/connection_cext.py", line 179, in _open_connection
    self._cmysql.connect(**cnx_kwargs)
_mysql_connector.MySQLInterfaceError: Bad handshake

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/Charlie/Documents/python/myscript/mysql_insert.py", line 8, in <module>
    port="3306"
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/mysql/connector/__init__.py", line 172, in connect
    return CMySQLConnection(*args, **kwargs)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/mysql/connector/connection_cext.py", line 78, in __init__
    self.connect(**kwargs)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/mysql/connector/abstracts.py", line 735, in connect
    self._open_connection()
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/mysql/connector/connection_cext.py", line 182, in _open_connection
    sqlstate=exc.sqlstate)
mysql.connector.errors.OperationalError: 1043 (08S01): Bad handshake

这是脚本中的代码

import mysql.connector

mydb = mysql.connector.connect(
  host="external-db.s157688.gridserver.com",
  user="myusername",
  passwd="mypassword",
  database="mydatabase",
  port="3306"
)

mycursor = mydb.cursor()

sql = "INSERT INTO test (post_id, title) VALUES (%s, %s)"
val = [
  ('Peter', 'Lowstreet 4'),
  ('Amy', 'Apple st 652'),
  ('Hannah', 'Mountain 21'),
  ('Michael', 'Valley 345'),
  ('Sandy', 'Ocean blvd 2'),
  ('Betty', 'Green Grass 1'),
  ('Richard', 'Sky st 331'),
  ('Susan', 'One way 98'),
  ('Vicky', 'Yellow Garden 2'),
  ('Ben', 'Park Lane 38'),
  ('William', 'Central st 954'),
  ('Chuck', 'Main Road 989'),
  ('Viola', 'Sideway 1633')
]

mycursor.executemany(sql, val)

mydb.commit()

print(mycursor.rowcount, "was inserted.")

我试图谷歌它但没有找到任何解决方案，有人可以帮忙吗？

确保您已安装 mysql-connector 而不是 mysql-connector-python，以确保只需运行以下命令： pip3 uninstall mysql-connector-python pip3 install mysql-connector
