Question

我使用以下代码向我的Gmail帐户发送电子邮件。库（mailR）

    sender <- "*********@gmail.com"    
recipients <- c("**********@gmail.com")    
send.mail(from = sender,    
             to = recipients,    
             subject = "Test",    
              body = "Test",    
          smtp = list(host.name = "smtp.gmail.com", port = 465,    
                      user.name = "**********@gmail.com",              
                      passwd = "*********", ssl = TRUE),    
          authenticate = TRUE,    
          send = TRUE)

我曾尝试使用不同的端口，如25,522，但没有任何作用。此外，我还启用了访问不太安全的应用程序＆＃39;。请帮助。

但是我收到了一个错误：

Answer 1

因为，在这个问题上没有人真正帮助我，但我一直在尝试和探索事情，并得到一个链接/解决方案来解决我的问题。

发送电子邮件可以使用sendmailR或mailR包完成，但您需要拥有正确的SMTP设置（来自您的IT），否则无论您尝试多少都无法正常工作。无论如何，我发现mailR对我来说没什么用。
另一部分是设置API并获取您的Gmail帐户的客户端ID，然后使用此文件构建连接并发送电子邮件。执行此操作的链接如下所示。

希望这能帮助所有遇到问题的人和我一样。
