true
if the SMTP
session has been started.
Opens a TCP connection and starts the SMTP
session.
helo
is the HELO domain that you’ll dispatch mails from; see the discussion in the overview notes.
If both of user
and secret
are given, SMTP
authentication will be attempted using the AUTH command. authtype
specifies the type of authentication to attempt; it must be one of :login, :plain, and :cram_md5. See the notes on SMTP
Authentication in the overview.
When this methods is called with a block, the newly-started SMTP
object is yielded to the block, and automatically closed after the block call finishes. Otherwise, it is the caller’s responsibility to close the session when finished.
This is very similar to the class method SMTP.start
.
require 'net/smtp' smtp = Net::SMTP.new('smtp.mail.server', 25) smtp.start(helo_domain, account, password, authtype) do |smtp| smtp.send_message msgstr, 'from@example.com', ['dest@example.com'] end
The primary use of this method (as opposed to SMTP.start
) is probably to set debugging (set_debug_output
) or ESMTP (esmtp=
), which must be done before the session is started.
If session has already been started, an IOError
will be raised.
This method may raise:
Returns the path from an FTP
URI
.
RFC 1738 specifically states that the path for an FTP
URI
does not include the / which separates the URI
path from the URI
host. Example:
ftp://ftp.example.com/pub/ruby
The above URI
indicates that the client should connect to ftp.example.com then cd to pub/ruby from the initial login directory.
If you want to cd to an absolute directory, you must include an escaped / (%2F) in the path. Example:
ftp://ftp.example.com/%2Fpub/ruby
This method will then return “/pub/ruby”.
This is used as a predicate, and ought to be called first.
Gets all IP addresses for name
from the hosts file.
Creates a new DNS
resolver. See Resolv::DNS.new
for argument details.
Yields the created DNS
resolver to the block, if given, otherwise returns it.
Sets the resolver timeouts. This may be a single positive number or an array of positive numbers representing timeouts in seconds. If an array is specified, a DNS
request will retry and wait for each successive interval in the array until a successful response is received. Specifying nil
reverts to the default timeouts:
Example:
dns.timeouts = 3
Closes the DNS
resolver.
Gets all IP addresses for name
from the DNS
resolver.
name
can be a Resolv::DNS::Name
or a String
. Retrieved addresses will be a Resolv::IPv4
or Resolv::IPv6
Returns the namespace URL, if defined, or nil otherwise
e = Element.new("el") e.add_namespace("ns", "http://url") e.add_attribute("ns:a", "b") e.add_attribute("nsx:a", "c") e.attribute("ns:a").namespace # => "http://url" e.attribute("nsx:a").namespace # => nil
Returns a copy of this attribute
Make a copy of this object
Examples
c = CData.new( "Some text" ) d = c.clone d.to_s # -> "Some text"
Should be obvious
Creates a shallow copy of self.
d = Document.new "<a><b/><b/><c><d/></c></a>" new_a = d.root.clone puts new_a # => "<a/>"
