我正在尝试使用Embedly为给定网址生成缩略图。我需要缩略图小于最大尺寸,所以我像这样调用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
在任何一种情况下,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
}
请注意thumbnail_width
是399(比我传入的maxwidth
参数大)。我错过了一些明显的东西吗?
答案 0 :(得分:1)
maxwidth
仅适用于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)
