sendng email using gmail account

Hi

I have try the code from https://github.com/brunoos/luasec/wiki to send an email using gmail account. However, it got failure. Look at your comment at https://github.com/openresty/lua-nginx-module/issues/155, is openresty able to send an email using gmail account instead of using luasec written by brunos?

manchev

Hi,

You could use lua-resty-smtp [1] for that.

Use the patched rockspec here [2] to directly install it with luarocks.

[1]: https://github.com/duhoobo/lua-resty-smtp
[2]: https://raw.githubusercontent.com/blablacio/lua-resty-smtp/patch-1/rockspec/resty.smtp-0.0.2-1.rockspec

Never never use the luasec library in the context of OpenResty because
it will always block the nginx event loop and ruin your nginx's
performance.

Use a lua-resty-* library based on ngx_lua's own nonblocking cosocket
API (for example, you can check out Hungpu DU's lua-resty-smtp library
as suggested by Vladislav Manchev).

I tried that code but not success.... it gives me "socket does not have ssl support". Any advice for me to send an email using gmail account? I made changes to the existing sendmail.lua as below:

package.path = "/home/project/Lua/lua-resty-smtp-master/lib/?.lua;" .. package.path
local ltn12 = require("resty.smtp.ltn12")
local mime = require("resty.smtp.mime")
local smtp = require("resty.smtp")
local socket = require("socket")

function sendmail()
    from= "<abdulrah...@gmail.com>"

    rcpt= {
        "<abdulrah...@gmail.com>"
    }

    mesgt = {
        headers= {
            subject = mime.ew("中文标题", nil, {}),
            ["content-transfer-encoding"] = "quoted-printable",
            ["content-type"] = "text/plain; charset='utf-8'",
        },

        body= mime.qp("中文内容，HELLO WORLD. Fuck you mother fucker"),
    }

    r, e = smtp.send {
        from= from,
        rcpt= rcpt,
        source= smtp.message(mesgt),
        server= "smtp.gmail.com",
        --domain= "wireless-alarm",
        user= "abdulrah...@gmail.com",
        password= "XXXXXXX",
        create= socket.tcp,
        ssl= { enable= true, verify_cert= false },
    }

    print(r)
    print(e)
end

function main()
    sendmail()
end

main()

But in php, using Mail.php from pear package, they use SASL protocol for connectivity with gmail. Need clarification and help for this issue

In short the error occurs if your NGINX from OpenResty is not correctly
build with against OpenSSL libraries.

i also have the same issue,

ubuntu 14.04

openresty-1.7.4.1

rm -rf /opt/local/openresty

1. apt-get install openssl libssl-dev ...

2. cd openresty-1.7.4.1

3. config --with-luajit

4. make && make install

and the issue came out. what steps should be take to install openresty and resolve the issue ---socket does not have ssl support ?在 2014年9月26日星期五UTC+8上午11时37分01秒，Abdul Rahman Madeni写道：

You mean the cosocket lacks the sslhandshake() method? If yes, then
you're using an older ngx_lua module (or an older OpenResty).

Are you 100% sure you are using the nginx of the openresty you just
built? The nginx visible to your default PATH environment might not be
the nginx you actually want.

OpenResty 1.7.4.1 should have SSL/TLS cosocket support (by default) in
its own ngx_lua.

Also, if your nginx server of an older OpenResty is already running,
you need a full server restart rather than HUP reload (which does not
use the new nginx executable).

Not quite sure why you're trying to use LuaSocket, but it does not make any sense at all in the OpenResty context.

Remove the "create= socket.tcp," line and you should be fine.

Please, note that the create option is intended for socket reuse rather than plugging in third party networking libraries.

Steps:

operated as follows, this issue perplexed me two monthes, and Stefan Parvu said that " is not correctly build with against OpenSSL libraries."

But i can not find out where is not correct

#apt-get install libreadline-dev libncurses5-dev libpcre3-dev libssl-dev perl mak

#apt-get install openssl libssl-dev

libssl-dev is already the newest version.

openssl is already the newest version.

#rm -rf /usr/local/openresty/ ----->((be sure use the latest openresty)

#killall nginx

# ps aux | grep nginx | grep -v "grep" -----> (be sure there is no nginx running)

#cd ngx_openresty-1.7.4.1

#./configure --with-luajit

#make && make install

#cd /opt/testEmail

#/usr/local/openresty/nginx/sbin/nginx -V

nginx version: openresty/1.7.4.1

built by gcc 4.8.1 (Ubuntu 4.8.1-2ubuntu1~12.04)

TLS SNI support enabled

#/usr/local/openresty/nginx/sbin/nginx -p `pwd`/ -c conf/nginx-site &

remove the line ： create= socket.tcp,

and it works, you should also add "resover 8.8.8.8" into nginx config file's http block.

We used to have a problem with NGINX not being correctly used (We were using by mistake on one of our dev machines a
different NGINX than the OpenResty ... )

Your sendmail function is not okay. This is a sample application:
local config = require("config")
local smtp = require("resty.smtp")
local mime = require("resty.smtp.mime")
local ltn12 = require("resty.smtp.ltn12")

-- ...
-- Suppose your mail data in table `args` and default settings 
-- in table `config.mail`
-- ...

local mesgt = { 
    headers= {
        subject= mime.ew(args.subject or config.mail.SUBJECT, nil, 
                         { charset= "utf-8" }), 
        ["content-transfer-encoding"] = "BASE64",
        ["content-type"] = "text/plain; charset='utf-8'",
    },

    body= mime.b64(args.body)
}   

local ret, err = smtp.send {
    from= args.from or config.mail.FROM,
    rcpt= rcpts,
    user= args.user or config.mail.USER,
    password= args.password or config.mail.PASSWORD,
    server= args.server or config.mail.SERVER,
    domain= args.domain or config.mail.DOMAIN,
    source= smtp.message(mesgt),
}   
.

Hi... I did the changes suggested by you and it works... and I am trying to send email with attachement (i.e. png or pdf files) using the code in http://w3.impa.br/~diego/software/luasocket/smtp.html as below:

-- load the smtp support and its friends
local smtp = require("socket.smtp")
local mime = require("mime")
local ltn12 = require("ltn12")

-- creates a source to send a message with two parts. The first part is 
-- plain text, the second part is a PNG image, encoded as base64.
source = smtp.message{
  headers = {
     -- Remember that headers are *ignored* by smtp.send. 
     from = "Sicrano de Oliveira <sicrano@example.com>",
     to = "Fulano da Silva <fulano@example.com>",
     subject = "Here is a message with attachments"
  },
  body = {
    preamble = "If your client doesn't understand attachments, \r\n" ..
               "it will still display the preamble and the epilogue.\r\n" ..
               "Preamble will probably appear even in a MIME enabled client.",
    -- first part: no headers means plain text, us-ascii.
    -- The mime.eol low-level filter normalizes end-of-line markers.
    [1] = { 
      body = mime.eol(0, [[
        Lines in a message body should always end with CRLF. 
        The smtp module will *NOT* perform translation. However, the 
        send function *DOES* perform SMTP stuffing, whereas the message
        function does *NOT*.
      ]])
    },
    -- second part: headers describe content to be a png image, 
    -- sent under the base64 transfer content encoding.
    -- notice that nothing happens until the message is actually sent. 
    -- small chunks are loaded into memory right before transmission and 
    -- translation happens on the fly.
    [2] = { 
      headers = {
        ["content-type"] = 'image/png; name="image.png"',
        ["content-disposition"] = 'attachment; filename="image.png"',
        ["content-description"] = 'a beautiful image',
        ["content-transfer-encoding"] = "BASE64"
      },
      body = ltn12.source.chain(
        ltn12.source.file(io.open("image.png", "rb")),
        ltn12.filter.chain(
          mime.encode("base64"),
          mime.wrap()
        )
      )
    },
    epilogue = "This might also show up, but after the attachments"
  }
}

-- finally send it
r, e = smtp.send{
    from = "<sicrano@example.com>",
    rcpt = "<fulano@example.com>",
    source = source,
}

However, the code unable to send attachement... any advice
