Vpim::Vcard - 解析 vcard 2.1
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 Vpim::Vcard.decode(data)
时,出现错误:
undefined method `each' for #<String:0x0000000928e778>
StackTrace:
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'
我尝试运行 gem install vcard
并在RailsApp初始化后需要'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=
(异常类是 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导轨模型。 当我尝试直接从脚本/控制台解码时(在安装了 vcard gem 并直接包括“vcard”之后),我成功获得了 Vcard 对象。
StackTrace:

How is it possible to parse Vcard 2.1 in Rails?
My code must parse Vcard 2.1 format.
I am using vpim(there are no other libs)
When I run Vpim::Vcard.decode(data)
I get error:
undefined method `each' for #<String:0x0000000928e778>
StackTrace:
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'
I tryed to run gem install vcard
and to require 'vcard' directry(config.gem does not include this file after vpim gem) after RailsApp initialization.(config.gem 'vpim'
is included in environment.rb)
By this way I get another error:
;=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 class is Vpim::InvalidEncodingError
)
Vcard code I try parse:
BEGIN:VCARD
VERSION:2.1
REV:20090710T151929Z
TEL;CELL:80954130722
X-CLASS:private
END:VCARD
It is interesting that second error is when I am decoding inside a Rails model.
When I try to decode directly from script/console (after installinv vcard gem and direct including 'vcard') I succesfuly get Vcard object.
StackTrace:
Vpim::InvalidEncodingError (;=D0=9D=D0=B0=D0=B4=D1=80=D0=B0=20=D0=B1=D0=B0=D0=BD=D0=BA=20=D0=BE=D0=BB=):

问题是
String#each
已在 Ruby 1.9.1 中删除。 (其功能在String#each_line
中保留)。要修复/解决此错误,请执行以下任一操作:Vpim
代码以适当地使用String#each_line
(并向 vpim 作者发送补丁)您可以对
String 进行猴子修补 类,通过定义
each
方法切换到 vcard gem,取自
Vpim
并且支持 Ruby 1.9.1。我推荐第四个选项。
The problem is that
String#each
has been removed in Ruby 1.9.1. (Its functionality endures inString#each_line
). To fix/work around this bug, do any of the following:Vpim
code to useString#each_line
appropriately (and send the vpim authors a patch)You can monkey-patch the
String
class by defining theeach
methodSwitch to the vcard gem, which is taken from
Vpim
and which has Ruby 1.9.1 support.I recommend the 4th option.
