如何使用机器人中的用户输入向相关人员发送电子邮件

Question

我创建了一个QnA bot。为此，我在QnA制造商中添加了一些问题和答案，并在我的机器人应用程序中使用它。

如果用户询问预定义问题中不存在的问题，则机器人需要从用户处获得未回答的问题。对于该机器人将询问用户的详细信息，如电子邮件ID。然后机器人需要发送电子邮件给专业人士（机器人已经有他的电子邮件ID），电子邮件的内容应该是未答复的问题。我附上了我的代码。

但我无法发送邮件。我在模拟器中输入电子邮件ID后说：

例外：发送邮件失败。[文件类型'text / plain']。

那么如何将邮件从机器人发送给特定的人。

我尝试使用您提供的代码重现该问题，我测试您的代码以使用我的gmail帐户发送电子邮件，这对我有用。

邮件发送失败。

要解决此问题，请尝试：

• 确保您提供正确的凭据（userName＆password）
• 检查端口587是否被阻塞
• 检查您是否启用“允许安全性较低的应用”
