Embedly.oembed不遵守最大寬度參數

Question

我正在嘗試使用Embedly生成給定網址的縮略圖。我需要縮略圖爲比最大尺寸更小，所以調用API像這樣：

url = "http://embed.ly" 
embedly_api = Embedly::API.new(key: ENV['EMBEDLY_KEY']) 
obj = embedly_api.oembed(url: url, maxwidth: 50, type: 'photo').first 

json_obj = JSON.pretty_generate(obj.marshal_dump) 

或

http://api.embed.ly/1/oembed?key=[KEY_VALUE]&url=http://embed.ly&maxwidth=50&type=photo 

在任一情況下，結果是：

{ 
    provider_url: "http://embed.ly", 
    description: "Embedly delivers the ultra-fast,...", 
    title: "Embedly makes your content more engaging and easier...", 
    mean_alpha: 32.7480314961, 
    thumbnail_width: 399, 
    url: "http://embed.ly", 
    thumbnail_url: "http://embed.ly/static/images/logos/logo_color.png?v=4b245", 
    version: "1.0", 
    provider_name: "Embedly", 
    type: "link", 
    thumbnail_height: 127 
} 

通知thumbnail_width是399（這比我通過的maxwidth參數大）。我在這裏錯過了很明顯的東西嗎

Answer 1

maxwidth只適用於html，圖像可以是任何寬度。

儘管嵌入確實允許您設置image_width。嘗試：

embedly_api.oembed(url: url, maxwidth: 50, type: 'photo', image_width: 50)
