Python ValueError:以10为基数的int（）的文本无效：'；密码'；将SQLALCHEMY与google应用程序引擎结合使用

我一直在与SQLAlchemy斗争，并让它与谷歌应用程序引擎一起工作。当然，它在本地工作：eyeroll:。
我一辈子都搞不懂

以下是日志：

您缺少了

@

符号，这不应该是：

'mysql吗+pymysql://root:password@主机：端口/dbname'

？您正在向

端口

输入一个字符串“password”，其中它希望可以转换为整数。将端口指定为整数。通常像

//root:password/

这样的url会表示名为“root”的主机和名为“password”的端口，这当然很愚蠢，因此会出现错误。@GAEfan是的，但当我尝试这样做时，它给了我另一个错误：Google cloud sql：在“读取初始通信包”时与MySQL服务器失去连接不完全确定当我使用Google cloud的sql作为well@IljaEverilä你可能有一些东西，但到目前为止，所有文档都说我应该这样设置连接URL：/不完全是。在凭据后面加上“@”，这样url解析器就可以将它们与主机：端口对区分开来。您好@ingenium21，这太好了！请接受答案。
