我的代碼必須解析Vcard 2.1格式。 我使用VPIM(沒有其他庫)Vpim :: Vcard - 解析vcard 2.1
當我運行Vpim::Vcard.decode(data)
我得到錯誤:
undefined method `each' for #<String:0x0000000928e778>
堆棧跟蹤:
NoMethodError (undefined method `each' for #<String:0x0000000928e778>):

vpim (0.695) lib/vpim/vcard.rb:692:in `decode'
app/models/event.rb:71:in `block (2 levels) in parse_data'
我tryed運行gem install vcard
,並要求「電子名片'在使用RailsApp初始化後,directry(config.gem在vpim gem之後不包含此文件)(config.gem 'vpim'
包含在environment.rb中) 通過這種方式,我得到另一個錯誤:
;=D0=9D=D0=B0=D0=B4=D1=80=D0=B0=20=D0=B1=D0=B0=D0=BD=D0=BA=20=D0=BE=D0=BB=
(Exception類是Vpim::InvalidEncodingError
)
維卡代碼,我嘗試解析:
BEGIN:VCARD
VERSION:2.1
REV:20090710T151929Z
TEL;CELL:80954130722
X-CLASS:private
END:VCARD
有趣的是,當我一個Rails模型內部解碼第二個錯誤。 當我嘗試從腳本/控制檯直接解碼(在installinv vcard gem和直接包含'vcard'後),我成功獲取Vcard對象。

這裏是IRB axample:

怎麼可能來剖析vCard 2.1在軌道上?
你能發佈更多的代碼嗎? 你嘗試解析一個io對象而不是字符串嗎? 你正在使用哪個ruby版本? – elmac 2010-08-11 07:48:49
你可以發佈完整的堆棧跟蹤嗎? – 2010-08-12 09:56:46
我已經更新了這個問題。 – 2010-08-12 13:01:30
