Geo*_*tas 21 email smtp r email-attachments
按照此相关问题中提供的说明,我能够发送html格式的邮件消息.现在的问题是:我应该如何修改以下代码,以便将一个或多个文件(任何类型)附加到此消息中？
library(sendmailR)
from <- "<sendmailR@myserver.mycompany.com>"
to <- c("<someone@mycompany.com>","<anotherone@mycompany.com>")
subject <- iconv("Message Title", to = "utf8")
msg <- "<hr size='2' width='33%' style='text-align: left;'><font size='2'>
<i>This email was sent automatically using <a href='http://finzi.psych.upenn.edu/R/library/sendmailR/html/00Index.html' rel='nofollow' target='_blank'>sendmailR</a>.<br>
Please do not reply directly to this e-mail.</i></font>"
msg <- iconv(msg, to = "utf8")
sapply(to,function(x) sendmail(from, x, subject, msg, control=list(smtpServer="###.###.###.###"), headers=list("Content-Type"="text/html; charset=UTF-8; format=flowed")))
使用mailR包(https://github.com/rpremraj/mailR),您可以发送HTML电子邮件并轻松附加文件,如下所示:
send.mail(from = "sender@gmail.com",
to = c("recipient1@gmail.com", "recipient2@gmail.com"),
subject = "Subject of the email",
body = "<html>The apache logo - <img src=\"http://www.apache.org/images/asf_logo_wide.gif\"></html>",
html = TRUE,
smtp = list(host.name = "smtp.gmail.com", port = 465, user.name = "gmail_username", passwd = "password", ssl = TRUE),
attach.files = c("./download.log", "upload.log"),
authenticate = TRUE,
send = TRUE)
编辑(2014-05-13):
mailR已更新为允许不同的字符编码.以下是将消息作为UTF-8发送的示例.
send.mail(from = "Sender Name <sender@gmail.com>",
to = "recipient@gmail.com",
subject = "A quote from Gandhi",
body = "In Hindi : ???? ?? ?????? ???? ???? ??????? ?? ????? ???
English translation: An ounce of practice is worth more than tons of preaching.",
encoding = "utf-8",
smtp = list(host.name = "smtp.gmail.com", port = 465, user.name = "gmail_username", passwd = "password", ssl = T),
authenticate = TRUE,
send = TRUE)
一个工作(至少对我来说)功能:
sendMessage<-function(contents,subject,from,to,attMIME,attachment,control){
msg<-list(contents,sendmailR:::.file_attachment(attachment,attachment,attMIME));
sendmail(from=from,to=to,subject=subject,msg=msg,control=control);
}
可以像这样使用:
png('a.png');hist(rnorm(700));dev.off()
sendMessage('Here you have a nice histogram:',
'Nice picture',
'from@example.com',
'to@example.com',
'image/png',
'a.png',list(smtpServer="..."))
请注意,此示例发送的邮件可能会被标记为垃圾邮件,因为它是一个简短的文字和一张大图片 - 但是对于较大的邮件而言,比方说它应该通过pdf附件.如果没有,您可以考虑添加消息的文本版本.
编辑(现在不太相关):可以在此处找到有关如何制作MIME消息的最深入见解.
请注意，sendmailR通过msg列出mime_type对象列表可以立即使用当前版本的支持附件，即现在
sendmail( from,to,subject,
msg=list(mime_part("Here's an attachment for you!"),
mime_part(attachmentFileName)), control, headers)`

下面是一个为日常批处理作业设置的示例，例如在 R 中使用 sendmail() 进行设置（可通过 sendmailR 包获得），并带有多个附件（一个 CSV、一个 PDF）：
设置要在文件名中引用的日期信息：
> yesterday_date_stuff <- new.env()
> yesterday_date_stuff[['month']] <- strftime(Sys.Date()-1, format="%m")
> yesterday_date_stuff[['day']] <- strftime(Sys.Date()-1, format="%d")
> yesterday_date_stuff[['year']] <- strftime(Sys.Date()-1, format="%y")
> yesterday_date_stuff$month
[1] "03"
> yesterday_date_stuff$day
[1] "29"
> yesterday_date_stuff$year
[1] "17"
现在，在本文末尾创建 sendmail() 函数所需的一些信息：
> from <- "youremail@whateveryourmailserveris.com"
> to <- c("person_A_to_send_email_to@whatever.com", "person_B_to_send_email_to@whatever.com", "person_C_to_send_email_to@whatever.com")
> subject <- paste("whatever you want subject line to read for batch job analyzing data for ", yesterday_date_stuff$month, "/", yesterday_date_stuff$day, "/", yesterday_date_stuff$year, sep="")
> body <- "Text to insert into the body of your email"
在此指定邮件服务器：
> mailControl=list(smtpServer="mail.whateveryourmailserveris.com")
定义附件 1 路径和名称：
> attachmentPath1 <- paste("file1name", "_", yesterday_date_stuff$month, yesterday_date_stuff$day, yesterday_date_stuff$year, ".csv", sep="")
> attachmentName1 <- paste("file1name", "_", yesterday_date_stuff$month, yesterday_date_stuff$day, yesterday_date_stuff$year, ".csv", sep="")
定义附件 1 对象：
> attachmentObject1 <- mime_part(x=attachmentPath1,name=attachmentName1)
定义附件 2 路径和名称：
> attachmentPath2 <- paste("file2name", "_", yesterday_date_stuff$month, yesterday_date_stuff$day, yesterday_date_stuff$year, ".pdf", sep="")
> attachmentName2 <- paste("file2name", "_", yesterday_date_stuff$month, yesterday_date_stuff$day, yesterday_date_stuff$year, ".pdf", sep="")
定义附件 2 对象：
> attachmentObject2 <- mime_part(x=attachmentPath2,name=attachmentName2)
现在将电子邮件正文与附件结合起来：
> bodyWithAttachment <- list(body,attachmentObject1, attachmentObject2)
> bodyWithAttachment
[[1]]
[1] "Text to insert into the body of your email"
[[2]]
<environment: 0x000000004efff188>
attr(,"class")
[1] "mime_part"
[[3]]
<environment: 0x00000000407a1b68>
attr(,"class")
[1] "mime_part"
使用 sendmail() 函数发送电子邮件：
> sendmail(from=from, to=to, subject=subject, msg=bodyWithAttachment, control=mailControl)
