R mailR包發送消息給STMP服務器（gmail）

Question

我一直在用mailR軟件包來從我的Gmail帳戶發送郵件，但到目前爲止我一直無法使它工作。其代碼如下（與隱私/安全「AAAA」取代電子郵件和密碼）：

library(mailR) 

sender <- 'aaaa@gmail.com' 
recipients <- c('aaaa@gmail.com') 
send.mail(from = sender, 
       to = recipients, 
       subject = 'My bot sent this', 
       body = 'Test Successful', 
       smtp = list(host.name = 'stmp.gmail.com', port= 587, 
           user.name = 'aaaa@gmail.com', 
           passwd = 'aaaa', tls= TRUE), 
       authenticate = TRUE, 
       send = TRUE) 

從我的理解，這似乎是一個適當的設置爲這個包。此外，我已確保雙重登錄已關閉，並且已啓用「允許訪問不太安全的應用程序」。我也用tls和ssl（完成適當的端口）嘗試了這一點，這沒有什麼區別。

當我運行代碼，我得到了以下錯誤：

爲了記錄在案，這裏是回溯輸出，以及：

4: eval(expr, envir, enclos) 
3: eval(ei, envir)

任何想法是怎麼回事？

Answer 1

由於您要求使用mailr軟件包提供故障排除解決方案，因此如果您打算嘗試使用其他軟件包，請使用gmailr。

install.packages('gmailr') 
library(gmailr) 
setwd() #set to desired working directory 
gmail_auth() 

mail <- mime(
    To = "to_address@domain.com", 
    From = "from_address@domain.com", 
    Subject = "My bot sent this", 
    body = "Test successful") 
send_message(mail) 

當您使用gmail_auth功能，如果你想連接到您的Gmail帳戶，將交互詢問。請注意，使用通過公共應用程序連接的gmailR軟件包。

通過在終端中輸入'yes'並單擊瀏覽器中的'接受'，您將在當前工作目錄（爲什麼我們將開始設置工作目錄）中存儲一個.httr-auth標記（加密用戶名和密碼）。您可以通過在終端中運行list.files(all = T)來查看文件。這允許您重新運行代碼，而無需執行。）將物理代碼中的密碼存儲在您的用戶名中，並b）以交互方式「重新接受」連接。

您插入錯誤的主機名：host.name = 'stmp.gmail.com' 該協議是SMTP，所以host.name = 'smtp.gmail.com'
