Question

我想使用Linux外部命令“mail”从scala发送电子邮件。命令执行有效，只是我在设置主题字符串时遇到麻烦，这里有一些尝试：

SENT OK

scala> val email="me@email.it"
  email: String = me@email.it
scala> val result = "echo ECCO" #| s"mail -s ciao_bello $email " !
warning: there was one feature warning; re-run with -feature for details
result: Int = 0

SENT但主题：ciao

scala> val subject="ciao bello !"
  subject: String = ciao bello !
scala> val result = "echo BODY" #| s"mail -s $subject $email " !
warning: there was one feature warning; re-run with -feature for details
rewrite: excessive recursion (max 50), ruleset Canonify2
result: Int = 0

SENT但主题：“ciao”

scala> val subject= "\"ciao bello !\""
  subject: String = "ciao bello !"
scala> val result = "echo BODY" #| s"mail -s $subject $email " !
warning: there was one feature warning; re-run with -feature for details
!"... Unbalanced '"'
result: Int = 0

不是

scala> val result = "echo BODY" #| s"mail -s \"ciao bello\" $email " !
<console>:10: error: value ciao is not a member of `enter code here`scala.sys.process.ProcessBuilder
       val result = "echo BODY" #| s"mail -s \"ciao bello\" $email " !                                               
<console>:10: error: not found: value bello
       val result = "echo BODY" #| s"mail -s \"ciao bello\" $email " !

我如何处理包含多个单词的主题？

有些失败者给了我解决方案，但只是在正确发送电子邮件之前进行了调整：

scala> val subject="\"ciao bello !\""
subject: String = "ciao bello !"

scala> val result = Seq("sh", "-c", s"echo BODY | mail -s $subject $email") !
warning: there was one feature warning; re-run with -feature for details
result: Int = 0

谢谢，欢呼！

SCALA：带有“主题”的外部命令“mail”
