无法使用应用引擎邮件包发送电子邮件？
无法使用应用引擎邮件包发送电子邮件？
提问于 2018-02-01 20:02:59
我是AppEngine和golang的新手，并尝试使用以下代码发送电子邮件，但我没有收到任何邮件。云你来帮我修一下吧。
现在我直接从app engine运行这段代码，当我从本地开发运行时，如何从本地开发服务器测试它：Edited1:
dev_appserver.py --smtp_host=smtp.gmail.com --smtp_port=25
--smtp_user=venkatanagarajas@gmail.com --smtp_password=****** E:\GoWork\src\email\appenginemail我得到了下面的错误：
From: venkatanagarajas@gmail.com
To: Srinadh <kasireddy002@gmail.com>
Subject: See you tonight

GAE未在本地服务器上运行，您必须在本地配置SMTP并调用其方法
步骤：
