Question

我需要从Ruby编程语言访问GNOME密钥环。但是，我找不到任何宝石的红宝石库。具体来说，我正在尝试获取桌面触控的Oauth键。

如何实现这一目标？

Answer 1

尝试keyring https://rubygems.org/gems/keyring/versions/0.3.1

它的工作方式与

一样简单

require 'keyring'
keyring = Keyring.new
my_password = keyring.get_password('service', 'username')

Answer 2

这在使用Gnome 3.28.2 / gnome-keyring 3.28.0 / Seahorse 3.20的Ubuntu 18.04上有效：

$ apt install libgnome-keyring-dev
$ gem install keyring

require 'keyring'
keyring = Keyring.new
keyring.set_password('service', 'username', 'password')
password = keyring.get_password('service', 'username')
# => "password"
keyring.delete_password('service', 'username')

不幸的是，keyring gem不允许您使用默认密钥环以外的任何其他内容。要使用其他钥匙圈，或者如果您只想剪裁中间人，则：

$ gem install gir_ffi-gnome_keyring

require 'gir_ffi-gnome_keyring'
service_name = 'MyApplication'
username = 'Blah'

attrs = GnomeKeyring::AttributeList.new
attrs.append_string 'service', service_name
attrs.append_string 'username', username
attrs.append_string 'arbitrary_values', "whatever"

status, item_id = GnomeKeyring.item_create_sync(
  "My Other Keyring",
  :generic_secret,
  "#{service_name} (#{username})",
  attrs,
  'my secret password',
  true
)

# Using default keyring:
# status, item_id = GnomeKeyring.item_create_sync(
#    nil,
#    :generic_secret,
#    "#{service_name} (#{username})",
#    attrs,
#    'my secret password',
#    true
#  )

# Method signature:
# .item_create_sync(keyring, type, display_name, attributes, secret, update_if_exists)

status, keys = GnomeKeyring.find_items_sync :generic_secret, attrs
keys.first.secret
# => "my secret password"

# NOTE: find_items_sync() will search all unlocked keyrings of the right type and will
# return an array of all matches. There doesn't seem to be a way of narrowing the search.

如果密钥环是未锁定的（可能是这样，因为默认情况下会使用您登录时会自动解除锁定的登录密钥环），因此读取和写入将正常进行。如果密钥环被锁定，那么在您进行任何读取或写入操作之前，系统都会提示您提供密码以解锁密钥环。

如果看到以下错误消息：

Typelib file for namespace 'GnomeKeyring' (any version) not found

然后，您可能需要安装gnome-keyring标头（apt install libgnome-keyring-dev）
