Overview

FTP ::Bundler::URI syntax is defined by RFC1738 section 3.2.

This class will be redesigned because of difference of implementations; the structure of its path. draft-hoffman-ftp-uri-04 is a draft but it is a good summary about the de facto spec. tools.ietf.org/html/draft-hoffman-ftp-uri-04

Constructor Details

.new(scheme, userinfo, host, port, registry, path, opaque, query, fragment, parser = nil, arg_check = false) ⇒ `FTP`

Description

Creates a new FTP object from generic URL components with no syntax checking.

Unlike build(), this method does not escape the path component as required by RFC1738; instead it is treated as per RFC2396.

Arguments are scheme, userinfo, host, port, registry, #path, opaque, query, and fragment, in that order.

Raises:

(InvalidURIError)

  end
end

Class Method Details

.build(args)

Description

Creates a new FTP object from components, with syntax checking.

The components accepted are userinfo, host, port, #path, and #typecode.

The components should be provided either as an Array, or as a Hash with keys formed by preceding the component names with a colon.

If an Array is used, the components must be passed in the order [userinfo, host, port, path, typecode].

If the path supplied is absolute, it will be escaped in order to make it absolute in the ::Bundler::URI.

Examples:

require 'bundler/vendor/uri/lib/uri'

uri1 = Bundler::URI::FTP.build(['user:password', 'ftp.example.com', nil,
  '/path/file.zip', 'i'])
uri1.to_s  # => "ftp://user:password@ftp.example.com/%2Fpath/file.zip;type=i"

uri2 = Bundler::URI::FTP.build({:host => 'ftp.example.com',
  :path => 'ruby/src'})
uri2.to_s  # => "ftp://ftp.example.com/ruby/src"

    args[3] = '/' + args[3].sub(/^\//, '%2F')

    args[:path] = '/' + args[:path].sub(/^\//, '%2F')

Args

v: String

Description

Public setter for the typecode v (with validation).

Usage

require 'bundler/vendor/uri/lib/uri'

uri = Bundler::URI.parse("ftp://john@ftp.example.com/my_file.img")
#=> #<Bundler::URI::FTP ftp://john@ftp.example.com/my_file.img>
uri.typecode = "i"
uri
#=> #<Bundler::URI::FTP ftp://john@ftp.example.com/my_file.img;type=i>

[ GitHub ]

# File 'lib/bundler/vendor/uri/lib/uri/ftp.rb', line 208


def typecode=(typecode)
  check_typecode(typecode)
  set_typecode(typecode)
  typecode
end

Instance Method Details

#check_typecode(v) (private)

Validates typecode v, returns true or false.

[ GitHub ]

# File 'lib/bundler/vendor/uri/lib/uri/ftp.rb', line 166


def check_typecode(v)
  if TYPECODE.include?(v)
    return true
  else
    raise InvalidComponentError,
      "bad typecode(expected #{TYPECODE.join(', ')}): #{v}"
  end
end

#merge(oth)

This method is for internal use only.

[ GitHub ]

# File 'lib/bundler/vendor/uri/lib/uri/ftp.rb', line 214


def merge(oth) # :nodoc:
  tmp = super(oth)
  if self != tmp
    tmp.set_typecode(oth.typecode)
  end

  return tmp
end

#path

Returns the path from an FTP ::Bundler::URI.

RFC 1738 specifically states that the path for an FTP ::Bundler::URI does not include the / which separates the ::Bundler::URI path from the ::Bundler::URI host. Example:

ftp://ftp.example.com/pub/ruby

The above ::Bundler::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”.
