Python电子邮件，[Errno 10061]无法建立连接，因为目标计算机主动拒绝了它

如Cid-EL所述，
您必须在GMAIL设置中启用安全性较低的应用

但是，打开该垂直选项并不安全。

Gmail提供了用于执行邮件操作的API。GMAIL API支持多种语言。

对于Python
API：带有Gmail的Python

对于Java
API：带有Gmail的Java

多一点的努力，但您可以建立安全的连接！

步骤1：开启GMAIL API

步骤2：安装Google客户端库

pip install --upgrade google-api-python-client

步骤3：使用GMAIL API发送邮件的代码示例

让我知道它是否行不通。

希望能帮助到你 ！！
