我正在尝试使用jython包在R中通过gmail发送带附件的电子邮件。我意识到jython是R中的python语言,问题是我不懂python,因此希望精通该语言的人可以帮助我。
为什么我要使用jython?因为SO-sendmailR上看起来很流行的其他电子邮件包不适用于gmail,因为它需要身份验证。
我使用的源代码是here。正如该人在链接中所说,原始代码是为没有附件的电子邮件构建的。我能够完美地运行这个版本没有错误(即能够通过R中的jython发送没有附件的电子邮件)。
但是,当我尝试添加一些脚本来包含附件时,它不起作用。 这是我尝试格式化此代码以处理附件(登录/电子邮件详细信息消失):
rJython <- rJython()
rJython$exec( "import smtplib" )
rJython$exec("from email.MIMEMultipart import MIMEMultipart")
rJython$exec("from email.MIMEBase import MIMEBase")
rJython$exec("from email.MIMEText import MIMEText")
rJython$exec("import email.utils")
rJython$exec("import smtplib")
rJython$exec("import os")
rJython$exec("from email.Utils import COMMASPACE, formatdate")
rJython$exec("from email import Encoders")
mail<-c(
#Email settings
"fromaddr = '@gmail.com'",
"toaddrs = '@gmail.com'",
"msg = MIMEMultipart('This is the body of the message.')",
"msg['From'] = email.utils.formataddr(('', fromaddr))",
"msg['To'] = email.utils.formataddr(('', toaddrs))",
"msg['Subject'] = 'Monitor'",
#SMTP server credentials
"username = ''",
"password = ''",
#Attach file
"files = 'E:/R/R_Data/output/S.pdf'",
"msg.attach(MIMEText('Your message contents'))",
"for f in files:",
" part = MIMEBase('application', 'octet-stream')",
" part.set_payload( open(f, 'rb').read() )",
" Encoders.encode_base64(part)",
" part.add_header('Content-Disposition', 'attachment;
" filename=\"S.pdf\"' % os.path.basename(files))",
" msg.attach(part)",
#Set SMTP server and send email, e.g., google mail SMTP server
"server = smtplib.SMTP('smtp.gmail.com:587')",
"server.ehlo()",
"server.starttls()",
"server.ehlo()",
"server.login(username,password)",
"server.sendmail(fromaddr, toaddrs, msg.as_string())",
"server.quit()")
jython.exec(rJython,mail)
当我运行它时,我收到以下错误:
Error in jython.exec(rJython, mail) : [Errno 2] ENOENT: 'E'
我的理解是Python中的这个错误意味着“没有这样的文件或目录”。
我可能做错的事情: 1.我是否错误地找到了我的附件目录? 2.代码是否无效,因为我只在目录中指定一个要附加的文件? 3.代码可以处理.pdfs吗? 4.代码的其他部分是否不正确?

以下是Google帐户和 mailR 包的示例:
library("mailR")
mail.from <- "yourmail@gmail.com"
mail.to <- "recipent@gmail.com"
mail.subject <- "subject"
smtp.host.name <- "smtp.gmail.com" # if you are using gmail smtp keep this
smtp.host.port <- 465 # if you are using gmail smtp keep this
smtp.user.name <- "yourAccountGmail@gmail.com"
smtp.host.passwd <- "yourpass"
smtp.ssl <- TRUE # if you are using gmail smtp keep this
smtp = list(host.name = smtp.host.name, port = smtp.host.port,
ssl=smtp.ssl, user.name = smtp.user.name,
passwd = smtp.host.passwd)
send.mail(from = mail.from,
to = mail.to,
subject = mail.subject,
body = "BodyText",
attach.files = c("path/to/your_file.ext"),
smtp = smtp,
authenticate = TRUE,
send = TRUE)
此外,首先为您的Google帐户启用SMTP访问权限。 https://www.google.com/settings/security/lesssecureapps

ENOENT
表示file not found - 您的代码只占用files
的第一个字符,当然 - 它不是有效的文件名。要使用jython通过带有PDF附件的Gmail成功发送电子邮件,您可以使用:
library(rJython)
rJython <- rJython()
rJython$exec( "import smtplib" )
rJython$exec("from email.MIMEMultipart import MIMEMultipart")
rJython$exec("from email.MIMEBase import MIMEBase")
rJython$exec("from email.MIMEText import MIMEText")
rJython$exec("import email.utils")
rJython$exec("import smtplib")
rJython$exec("import os")
rJython$exec("from email.Utils import COMMASPACE, formatdate")
rJython$exec("from email import Encoders")
mail<-c(
#Email settings
"fromaddr = '@gmail.com'",
"toaddrs = '@gmail.com'",
"msg = MIMEMultipart('This is the body of the message.')",
"msg['From'] = email.utils.formataddr(('', fromaddr))",
"msg['To'] = email.utils.formataddr(('', toaddrs))",
"msg['Subject'] = 'Monitor'",
#SMTP server credentials
"username = ''",
"password = ''",
#Attach file
"files = ['E:/R/R_Data/output/S.pdf']",
"msg.attach(MIMEText('Your message contents'))",
"for f in files:",
" part = MIMEBase('application', 'octet-stream')",
" part.set_payload( open(f, 'rb').read() )",
" Encoders.encode_base64(part)",
" part.add_header('Content-Disposition', 'attachment', filename='S.pdf')",
" msg.attach(part)",
#Set SMTP server and send email, e.g., google mail SMTP server
"server = smtplib.SMTP('smtp.gmail.com:587')",
"server.ehlo()",
"server.starttls()",
"server.ehlo()",
"server.login(username,password)",
"server.sendmail(fromaddr, toaddrs, msg.as_string())",
"server.quit()")
jython.exec(rJython,mail)
如另一个答案所述,你首先得到allow less secure apps to access your Gmail。然后结果将是:
