我的json数据

{
    "restaurant_name": "Restaurant 3",
    "address": "xyz address",

    "currency": "USD",
    "client_key": "12345",
    "client_name": "Client 3",
    "client_email": "[email protected]",
    "client_phone": "9876",
    "product_tier": "tier1",
    "brand_logo_large": {
        "ID": 37,
        "id": 37,
        "title": "bait-al-bahar-logo-design",
        "filename": "bait-al-bahar-logo-design.png",
        "filesize": 105071,
        "url": "http://codekyt.in/froodle-wp/wp-content/uploads/2019/01/bait-al-bahar-logo-design.png",

        "width": 600,
        "height": 500,
        "sizes": {
            "thumbnail": "http://codekyt.in/froodle-wp/wp-content/uploads/2019/01/bait-al-bahar-logo-design-150x150.png",

            "medium": "http://codekyt.in/froodle-wp/wp-content/uploads/2019/01/bait-al-bahar-logo-design-300x250.png",
            "medium-width": 300,
            "medium-height": 250,
            "medium_large": "http://codekyt.in/froodle-wp/wp-content/uploads/2019/01/bait-al-bahar-logo-design.png",
            "medium_large-width": 600,
            "medium_large-height": 500,
            "large": "http://codekyt.in/froodle-wp/wp-content/uploads/2019/01/bait-al-bahar-logo-design.png",
            "large-width": 600,
            "large-height": 500
        }
    }

在模型中，

include HTTParty

在控制器中

def index  
  require 'httparty'
  @category = HTTParty.get(
    'http://codekyt.in/froodle-wp/wp-json/data/v2/projects?client_key=12345',
    :headers =>{'Content-Type' => 'application/json'}
  )
end

在gemfile中，

gem 'httparty'
gem 'json'

在视野中，

<[e-mail] do |category|%>
<%=category["restaurant_name"]%>
<%=category["country"]%>
<%=category["currency"]%>
<%=category["usd"]%>
<%=category["client_key"]%>
<%=category["client_name"]%>
<%=category["client_email"]%>
<%=category["client_phone"]%>
<%=category["product_tier"]%>
<%=category["brand_logo_large"]%>
<%end%>

推荐答案

HTTParty.get返回封装的类HTTParty::Response的响应类型，您需要通过以下方式从中检索parsed response:

HTTParty.get returns an encapsulated response type of class HTTParty::Response, you need to retrieve the parsed response from that by:

response = HTTParty.get(
  'http://codekyt.in/froodle-wp/wp-json/data/v2/projects?client_key=12345',
  :headers =>{'Content-Type' => 'application/json'}
)
@category = response.parsed_response # this will return the json.

此外，您无需在@category上进行迭代，因为json对象是单个的，您可以直接使用它:

Also you do not need to iterate on @category in your case, the json object is singular and you can directly use it:

<%=@category["restaurant_name"]%>
<%=@category["country"]%>
<%=@category["currency"]%>
<%=@category["usd"]%>
<%=@category["client_key"]%>
<%=@category["client_name"]%>
<%=@category["client_email"]%>
<%=@category["client_phone"]%>
<%=@category["product_tier"]%>
<%=@category["brand_logo_large"]%>
