推荐答案

我不确定您要如何使用它.
无论如何，这都可以帮助您入门.
让我知道你是否被卡在某个地方.

I am not sure how you want to use it.
In any case this could help you get started.
Let me know if you get stuck somewhere.

1. 您必须先添加宝石并捆绑
   gem'embedly'，'〜> 1.9.1'(当前版本)

1. You have to add the gem first and bundle
   gem 'embedly', '~> 1.9.1' (what ever current version)

以下代码声明了一个名为display的方法，您可以在视图中使用该方法. 笔记
*您必须注册才能嵌入并获取API密钥.
*我建议您隐藏您的秘密密钥.
*您可以将以下代码放入模型文件或其他文件中
放置，但为了简单起见，将代码放在app/helpers文件夹下

The following code declares a method called display which you can use in your views. Notes
*You have to sign up to embedly and get an API key.
*I recommend you hide your secret key.
*You could put the following code in a model file or probably other
places but for the sake of simplicity put the code under the app/helpers folder

将以下代码放入: app/helpers/application_helper.rb

Put the following code in: app/helpers/application_helper.rb

require 'embedly'
require 'json'
def display(url)
  embedly_api = Embedly::API.new(key: THIS IS WHERE YOUR API KEY GOES)
  obj = embedly_api.oembed :url => url
  (obj.first.html).html_safe
end

1. 将此添加到您的视图中:
   例如app/views/welcome/index.html.erb

1. Put this in your views:
   for example app/views/welcome/index.html.erb

<%= display("http://vimeo.com/18150336") %>

转到: http://embed.ly/docs/explore/oembed?url=http%3A%2F%2Fvimeo.com%2F18150336

在这种情况下，它将显示您可以从该特定URL检索的嵌入内容" http://vimeo.com/18150336 ".

It will show you what embedly can retrieve from that particular url in this case "http://vimeo.com/18150336".

如果要检索标题，请更改:
(obj.first.html).html_safe to (obj.first.title).html_safe

If you want to retrieve the title, change :
(obj.first.html).html_safe to (obj.first.title).html_safe

如果要检索缩略图，请更改:
(obj.first.html).html_safe to (obj.first.thumbnail_url).html_safe

If you want to retrieve the thumbnail, change:
(obj.first.html).html_safe to (obj.first.thumbnail_url).html_safe

如果要检索图标，请更改:
(obj.first.html).html_safe to (obj.first.favicon_url).html_safe

If you want to retrieve the favicon, change :
(obj.first.html).html_safe to (obj.first.favicon_url).html_safe

如果要检索描述，请更改:
(obj.first.html).html_safe to (obj.first.description).html_safe

If you want to retrieve the description, change :
(obj.first.html).html_safe to (obj.first.description).html_safe

请注意，代码如何包装在().html_safe中，您也可以执行raw.() 如果您不这样做，则嵌入式代码将显示为字符串.

Note how code is wrapped in ().html_safe you could also do raw.() If you don't do this the embedded code will be shown as a string.
