上周群里有朋友在rails应用中需调用某api，不过接口非restful风格的，如要成功实现调用可以自行编写模块或引用第三方库，不过既然是在rails下，也可以拿AtciveResource来改动一下。

以下代码是个人做的一些小变更扩展来适应其api接口的调用－－以下代码纯属实践娱乐，贴出来备忘。

# File config/initializers/active_resource_ext.rb

module ActiveResource

 module Formats
 module NoneFormat
 extend self

 def extension
 ""
 end

 def mime_type
 ""
 end

 def encode(hash, options = nil)
 # 具体处理看实际需要
 #ActiveSupport::JSON.encode(hash, options)
 ""
 end

 # to Base.instantiate_collection
 def decode(json)
 # 具体处理看实际需要
 json
 end
 end
 end
 ＃ ActiveResource::Base
 class Base
 
 class 〈〈 self
 def element_path(id, prefix_options = {}, query_options = nil)
 prefix_options, query_options = split_options(prefix_options) if query_options.nil?
 if format.extension == ""
 "#{prefix(prefix_options)}#{collection_name}/#{URI.escape id.to_s}#{query_string(query_options)}"
 else
 "#{prefix(prefix_options)}#{collection_name}/#{URI.escape id.to_s}.#{format.extension}#{query_string(query_options)}"
 end
 end

 def new_element_path(prefix_options = {})
 if format.extension == ""
 "#{prefix(prefix_options)}#{collection_name}/new"
 else
 "#{prefix(prefix_options)}#{collection_name}/new.#{format.extension}"
 end
 end
 
 def collection_path(prefix_options = {}, query_options = nil)
 prefix_options, query_options = split_options(prefix_options) if query_options.nil?
 if format.extension == ""
 "#{prefix(prefix_options)}#{collection_name}#{query_string(query_options)}"
 else
 "#{prefix(prefix_options)}#{collection_name}.#{format.extension}#{query_string(query_options)}"
 end
 end

 def instantiate_collection(collection, prefix_options = {})
 if collection.is_a? Array
 collection.collect! { |record| instantiate_record(record, prefix_options) }
 else
 collection.to_s
 end
 end
 end
 end
 
 # ActiveResource::Connection
 class Connection
 private
 def build_request_headers(headers, http_method, uri)
 if format.mime_type == ""
 authorization_header(http_method, uri).update(default_header).update(headers)
 else
 authorization_header(http_method, uri).update(default_header).update(http_format_header(http_method)).update(headers)
 end
 end
 end
end

进入命令行模式
x:〉rails elvuel
x:〉cd elvuel
x:〉elvuel〉rake rails:freeze:gems
接着执行：(执行完成后　将在doc/api目录下会有一份完整的RAILS API文档)
x:〉elvuel〉rake doc:rails
