Any way to grab a logo icon from website URL, programmatically?
提问by mask
I am in the process of creating an activity where I will show the list of website visited with its logo and its alias name chosen by user.
我正在创建一个活动，我将在其中显示访问过的网站列表，其中包含用户选择的徽标和别名。
e.g.
例如
Recent Websites Visited
logo1 website1/alias name
logo2 website2/alias name
.
. so no
最近访问的网站
logo1 网站1/别名
logo2 网站2/别名
.
. 所以不行
The question is, (Ref. attached image) How to get website logo displayed on left side of http://?
问题是，（参考附图）如何让网站标志显示在 http:// 的左侧？

Use this website:
使用本网站：
https://besticon-demo.herokuapp.com/allicons.json?url=www.stackoverflow.com
https://besticon-demo.herokuapp.com/allicons.json?url=www.stackoverflow.com
It will find all logos for a website in multiple sizes and return a nice json string with meta data including the url to the icon. You simply replace www.stackoverflow.comwith your domain.
它将找到多种尺寸的网站的所有徽标，并返回一个带有元数据的漂亮 json 字符串，包括图标的 url。您只需替换www.stackoverflow.com为您的域。
The site also has a gui for entering in websites manually if you prefer:

It's called a favicon, and all you have to do is:
它被称为收藏夹图标，您所要做的就是：
- If there's an icon at
/favicon.ico, use that. - Otherwise, get the content of the page, and extract the location from
<link rel="shortcut icon" href="URL goes here" />. You'll need to use an HTML parser and find the<link>with arelof eithericonorshortcut icon.
- 如果 处有图标
/favicon.ico，请使用它。 - 否则，获取页面内容，并从 中提取位置。你需要使用一个HTML解析器，并找到了任或。
<link rel="shortcut icon" href="URL goes here" /><link>reliconshortcut icon

This method can be used to get Favicon Icon bitmap
此方法可用于获取 Favicon Icon 位图
private Bitmap fetchFavicon(Uri uri) {
final Uri iconUri = uri.buildUpon().path("favicon.ico").build();
Log.i(TAG, "Fetching favicon from: " + iconUri);
InputStream is = null;
BufferedInputStream bis = null;
try
{
URLConnection conn = new URL(iconUri.toString()).openConnection();
conn.connect();
is = conn.getInputStream();
bis = new BufferedInputStream(is, 8192);
return BitmapFactory.decodeStream(bis);
} catch (IOException e) {
Log.w(TAG, "Failed to fetch favicon from " + iconUri, e);
return null;
}
}

Here's a python library which tries to infer the logo image from a URL:
这是一个尝试从 URL 推断徽标图像的 python 库：
https://github.com/dcollien/urlimage
https://github.com/dcollien/urlimage
it parses the HTML at the url, and tries a whole bunch of things including:
它解析 url 处的 HTML，并尝试很多事情，包括：
- meta tag with itemprop="image" or property="image"
- meta tag with property="og:image:secure_url" or property="og:image"
- meta tag with name="twitter:image"
- meta tag for Microsoft tiles, with: name="msapplication-wide310x150logo", name="msapplication-square310x310logo", name="msapplication-square150x150logo", name="msapplication-square70x70logo"
- link tag with rel="apple-touch-icon"
- link tag with rel="icon"
- tries out "{scheme}://{domain}/favicon.ico" to see if it exists
- otherwise pulls out the first img tag (next to an h1)
- 带有 itemprop="image" 或 property="image" 的元标记
- 带有 property="og:image:secure_url" 或 property="og:image" 的元标记
- 名称为 =“twitter:image”的元标记
- Microsoft 磁贴的元标记，包括：name="msapplication-wide310x150logo", name="msapplication-square310x310logo", name="msapplication-square150x150logo", name="msapplication-square70x70logo"
- 带有 rel="apple-touch-icon" 的链接标签
- 带有 rel="icon" 的链接标签
- 尝试“{scheme}://{domain}/favicon.ico”以查看它是否存在
- 否则拉出第一个 img 标签（在 h1 旁边）
