true
if the POP3
session has started.
Starts a POP3
session.
When called with block, gives a POP3
object to the block and closes the session after block call finishes.
This method raises a POPAuthenticationError
if authentication fails.
Returns truth value if this object uses STARTTLS. If this object always uses STARTTLS, returns :always. If this object uses STARTTLS when the server support TLS, returns :auto.
Creates a new Net::SMTP
object and connects to the server.
This method is equivalent to:
Net::SMTP.new(address, port).start(helo_domain, account, password, authtype)
Net::SMTP.start('your.smtp.server') do |smtp| smtp.send_message msgstr, 'from@example.com', ['dest@example.com'] end
If called with a block, the newly-opened Net::SMTP
object is yielded to the block, and automatically closed when the block finishes. If called without a block, the newly-opened Net::SMTP
object is returned to the caller, and it is the caller’s responsibility to close it when finished.
address
is the hostname or ip address of your smtp server.
port
is the port to connect to; it defaults to port 25.
helo
is the HELO domain provided by the client to the server (see overview comments); it defaults to ‘localhost’.
The remaining arguments are used for SMTP
authentication, if required or desired. user
is the account name; secret
is your password or other authentication token; and authtype
is the authentication type, one of :plain, :login, or :cram_md5. See the discussion of SMTP
Authentication in the overview notes.
This method may raise:
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 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”
Completion
for hash key.
Gets the IP address of name
from the hosts file.
Gets all IP addresses for name
from the hosts file.
Gets the IP address of name
from the DNS
resolver.
name
can be a Resolv::DNS::Name
or a String. Retrieved address will be a Resolv::IPv4
or Resolv::IPv6
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
Creates a new IPv6
address from arg
which may be:
IPv6
returns arg
.
arg
must match one of the IPv6::Regex* constants
Evaluates whether the given string matches an entity definition, returning true if so, and false otherwise.
A predicate filters a node-set with respect to an axis to produce a new node-set. For each node in the node-set to be filtered, the PredicateExpr is evaluated with that node as the context node, with the number of nodes in the node-set as the context size, and with the proximity position of the node in the node-set with respect to the axis as the context position; if PredicateExpr evaluates to true for that node, the node is included in the new node-set; otherwise, it is not included.
A PredicateExpr is evaluated by evaluating the Expr and converting the result to a boolean. If the result is a number, the result will be converted to true if the number is equal to the context position and will be converted to false otherwise; if the result is not a number, then the result will be converted as if by a call to the boolean function. Thus a location path para is equivalent to para.
