Public Instance Methods

as_json (*)

Source

# File ext/json/lib/json/add/ostruct.rb, line 33
def as_json(*)
  klass = self.class.name
  klass.to_s.empty? and raise JSON::JSONError, "Only named structs are supported!"
  {
    JSON.create_id => klass,
    't'            => table,
  }
end

方法 OpenStruct#as_json 和 OpenStruct.json_create 可用于序列化和反序列化 OpenStruct 对象；参见 Marshal。

方法 OpenStruct#as_json 序列化 self，返回一个代表 self 的两元素哈希

require 'json/add/ostruct'
x = OpenStruct.new('name' => 'Rowdy', :age => nil).as_json
# => {"json_class"=>"OpenStruct", "t"=>{:name=>'Rowdy', :age=>nil}}

方法 JSON.create 反序列化这样的哈希，返回一个 OpenStruct 对象

OpenStruct.json_create(x)
# => #<OpenStruct name='Rowdy', age=nil>

to_json (*args)

Source

# File ext/json/lib/json/add/ostruct.rb, line 51
def to_json(*args)
  as_json.to_json(*args)
end

返回一个代表 self 的 JSON 字符串

require 'json/add/ostruct'
puts OpenStruct.new('name' => 'Rowdy', :age => nil).to_json

输出

{"json_class":"OpenStruct","t":{'name':'Rowdy',"age":null}}
