Question

我正在尝试使用Python的pymysql库连接到RDS实例。不幸的是，我又回来了一个异常。

这是我的Python代码：

import pymysql

#Connect
connection = pymysql.connect(host='jdbc:mysql://dbname.url.us-east-1.rds.amazonaws.com/dbname',
                             port='3306',
                             user='username',
                             password='pass',
                             database='dbname')

执行它时，我收到以下异常：

Traceback (most recent call last):
  File "/path/to/file/test.py", line 8, in <module>
    database='treemigodb')
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pymysql/__init__.py", line 94, in Connect
    return Connection(*args, **kwargs)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pymysql/connections.py", line 327, in __init__
    self.connect()
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pymysql/connections.py", line 629, in connect
    raise exc
pymysql.err.OperationalError: (2003, "Can't connect to MySQL server on 'jdbc:mysql://dbname.url.us-east-1.rds.amazonaws.com/dbname' ([Errno 8] nodename nor servname provided, or not known)")

这是我尝试过的：

我已经在AWS端打开了安全组以进行通信。我以前曾在Java中成功执行过此连接。 AWS已按原样进行配置。
在其他示例中，我看到host格式倾向于变化。因此，我尝试了： jdbc:mysql://dbname.url.us-east-1.rds.amazonaws.com/dbname

jdbc:mysql://url.us-east-1.rds.amazonaws.com/dbname

jdbc:mysql://dbname.url.us-east-1.rds.amazonaws.com/

jdbc:mysql://url.us-east-1.rds.amazonaws.com/

dbname.url.us-east-1.rds.amazonaws.com/dbname

url.us-east-1.rds.amazonaws.com/dbname

dbname.url.us-east-1.rds.amazonaws.com/

是否存在一些可能会丢失的潜在设置？我已经仔细检查了所有其他参数是否匹配。
