我的代码必须解析 Vcard 2.1 格式。我正在使用 vpim(没有其他库)
当我运行时Vpim::Vcard.decode(data)
出现错误:
undefined method `each' for #<String:0x0000000928e778>
堆栈跟踪:
NoMethodError (undefined method `each' for #<String:0x0000000928e778>):
vpim (0.695) lib/vpim/rfc2425.rb:82:in `unfold'
vpim (0.695) lib/vpim/rfc2425.rb:308:in `decode'
vpim (0.695) lib/vpim/vcard.rb:692:in `decode'
app/models/event.rb:71:in `block (2 levels) in parse_data'
在 RailsApp 初始化之后,我尝试运行gem install vcard
并要求 'vcard' 目录(config.gem 在 vpim gem 之后不包含此文件)。(config.gem 'vpim'
包含在 environment.rb 中)通过这种方式,我得到另一个错误:
;=D0=9D=D0=B0=D0=B4=D1=80=D0=B0=20=D0=B1=D0=B0=D0=BD=D0=BA=20=D0=BE=D0=BB=
(例外类是Vpim::InvalidEncodingError
)
我尝试解析的 Vcard 代码:
BEGIN:VCARD
VERSION:2.1
REV:20090710T151929Z
TEL;CELL:80954130722
X-CLASS:private
END:VCARD
有趣的是,第二个错误是当我在 Rails 模型中解码时。当我尝试直接从脚本/控制台解码时(在 installinv vcard gem 和直接包括'vcard'之后)我成功地得到了 Vcard 对象。

如何在 rails 中解析 Vcard 2.1?
