Embedly.oembed 未遵守 maxwidth 参数

Question

我正在尝试使用 Embedly 为给定的 url 生成缩略图。我需要缩略图小于最大尺寸，所以我这样调用 api：

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

无论哪种情况，结果都是：

{
  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
}

注意 thumbnail_width 是 399（比我为 maxwidth 参数传入的大）。我在这里遗漏了什么明显的东西吗？

maxwidth只适用于html，图片可以是任意宽度。

Embedly 允许您设置 image_width。尝试：

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