Prerequisites
- Products: Liquid UI WS, Liquid UI Server or Local DLL, Client Software
- Commands: WSCurl, pushbutton()
- File: wscurl.dll
Purpose
Send email using WSCurl from SAP.
User Interface
Create the file SAPLSMTR_NAVIGATION.E0100.sjs inside your script folder for customizing the SAP Easy Access screen.
//Now, let's start adding the script to the above file and save it.
Customization
- Logon to SAP, and create a toolbar pushbutton with the label Send Mail on the SAP Easy Access screen, as shown in the image below.
On the SAP screen, a pushbutton with the label "Send Mail" is created.
pushbutton([TOOLBAR], 'Send Mail', '?', {"process":sendmail});
- Add the following Liquid UI script to the above file and save it.
load('wscurl');
// Function to check if the string value is blank
function isBlank(jvar) {
if (jvar==void 0 || jvar=="" || jvar==null) {
return true;
} else {
return false;
}
}
function sendmail(){
/* Initialize the Curl object for making the call*/
var wsCurl = new Curl();
/* This is the URL for your mailserver. Note the use of port 587 here,
* instead of the normal SMTP port (25). Port 587 is commonly used for
* secure mail submission (see RFC4403), but you should use whatever
* matches your server configuration. */
// wsCurl.setopt(Curl.CURLOPT_URL, "smtp://smtp.google.com:587");
wsCurl.setopt(Curl.CURLOPT_URL, "smtp://mail.guixt.com:25");
/* In this example, we'll start with a plain text connection, and upgrade
* to Transport Layer Security (TLS) using the STARTTLS command. Be careful
* of using Curl.USESSL_TRY here, because if TLS upgrade fails, the transfer
* will continue anyway - see the security discussion in the libcurl
* tutorial for more details. Available 2nd Parameters are Curl.USESSL_NONE(0),
* Curl.USESSL_TRY(1), Curl.USESSL_CONTROL(2) or Curl.USESSL_ALL(3)*/
wsCurl.setopt(Curl.CURLOPT_USE_SSL, Curl.USESSL_ALL);
/* If your server doesn't have a valid certificate, then you can disable
* part of the Transport Layer Security protection by setting the
* CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST options to 0 (false).
* wsCurl.setopt(Curl.CURLOPT_SSL_VERIFYPEER, 0);
* wsCurl.setopt(Curl.CURLOPT_SSL_VERIFYHOST, 0);
* That is, in general, a bad idea. It is still better than sending your
* authentication details in plain text though.
* Instead, you should get the issuer certificate (or the host certificate
* if the certificate is self-signed) and add it to the set of certificates
* that are known to libcurl using CURLOPT_CAINFO.
* wsCurl.setopt(Curl.CURLOPT_CAINFO, "/path/to/certificate.pem");
*/
/* A common reason for requiring transport security is to protect
* authentication details (user names and passwords) from being "snooped"
* on the network. Here is how the user name and password are provided: */
// wsCurl.setopt(Curl.CURLOPT_USERNAME, "user@example.net");
// wsCurl.setopt(Curl.CURLOPT_PASSWORD, "P@ssw0rd");
wsCurl.setopt(Curl.CURLOPT_USERNAME, "benjamin.dasari@guixt.com");
wsCurl.setopt(Curl.CURLOPT_PASSWORD, " "); // Enter the Password
/* value for envelope reverse-path. '<' '>' are REQUIRED around the email addr*/
// wsCurl.setopt(Curl.CURLOPT_MAIL_FROM, "<email_of_sender@example.net>");
wsCurl.setopt(Curl.CURLOPT_MAIL_FROM, "<benjamin.dasari@guixt.com>");
/* Add two recipients, in this particular case they correspond to the
* To: and Cc: addressees in the header, but they could be any kind of
* recipient. */
// wsCurl.slist_append("<email_of_recipent@example.net>");
// wsCurl.slist_append("<email_of_cc_recipent@example.net>");
/* Set the curl object to attach the recipients added above
* The second parameter is a REQUIRED string to maintain the syntax,
* however it has no effect on the execution*/
// wsCurl.setopt(Curl.CURLOPT_MAIL_RCPT, "recipients");
/* Since the traffic will be encrypted, it is very useful to turn on debug
* information within libcurl to see what is happening during the transfer.
*/
wsCurl.setopt(Curl.CURLOPT_VERBOSE, 1);
/* Set the buffer header and the data for the e-mail that is being sent*/
var email = ["Date: Mon, 29 Nov 2010 21:54:29 +1100\n",
"To: <umang.desai@guixt.com>\n",
"From: <benjamin.dasari@guixt.com>\n",
"Message-ID: ddmmyyyy.hhmm@domain.com\n",
"Subject: WS embedded SMTP TLS MESSAGE\n",
"\n", /* empty line to divide headers from body, see RFC5322 */
"The body of the message starts here.\n",
"\n",
"It could be a lot of lines, could be MIME encoded, whatever.\n",
"Check RFC5322.\n", NULL ];
/* In this case, we're using a callback function to specify the data. You
* could just use the CURLOPT_READDATA option to specify a var to read from*/
wsCurl.setopt(Curl.CURLOPT_READDATA, email);
/* Final step is to call execute to dispatch email*/
wsCurl.exec();
/* Clean up the recipient list*/
wsCurl.slist_free_all();
/* Close the smtp connection for the mail server*/
wsCurl.close();
/* Remove any reference for Garbage Collection*/
wsCurl= NULL;
} - Clicking on the Send Mail toolbar pushbutton will send an email from SAP to the desired email address.
