我需要从我从路边提供的 JSON 响应中提取一些数据。
以前我没有调用 symbolize_keys,但我认为这会让我的尝试奏效。
控制器动作:
http = Curl.get("http://api.foobar.com/thing/thing_name/catalog_items.json?per_page=1&page=1") do|http|
http.headers['X-Api-Key'] = 'georgeBushSucks'
end
pre_keys = http.body_str
@foobar = ActiveSupport::JSON.decode(pre_keys).symbolize_keys
在视图中(获取未定义的方法 `current_price' )
@foobar.current_price
我也试过@foobar.data[0]['current_price']
同样的结果
动作的 JSON 响应:
