You should be fine with url_to_postid()[see documentation] which is located in rewrite.php. I used it in a plugin of mine last year, works like a charm.
您应该可以使用位于 rewrite.php 中的url_to_postid()[参见文档]。我去年在我的一个插件中使用了它，效果很好。

I've got a dedicated (& documented) function for that:
我有一个专门的（和记录的）功能：
get_page_by_path( $page_path, $output, $post_type );
Retrieves a page given its path.
检索给定路径的页面。
Where $page_pathis
哪里$page_path是
[...] the equivalent of the 'pagename' query, as in: 'index.php?pagename=parent-page/sub-page'.
[...] 相当于“pagename”查询，如：“index.php?pagename=parent-page/sub-page”。
See Function Reference/get page by path
Example:
例子：
// Assume 'my_permalink' is a post.
// But all types are supported: post, page, attachment, custom post type, etc.
// See http://codex.wordpress.org/Post_Types
get_page_by_path('my_permalink', OBJECT, 'post');

Thisworks for regular post types AND custom post types. url_to_postid()only works for regular posts.
这适用于常规帖子类型和自定义帖子类型。url_to_postid()仅适用于常规帖子。

url_to_postid()as of 3.7.0: This function now supports custom post types (see Trac tickets #19744, #25659).
url_to_postid()截至3.7.0：此功能现在支持自定义帖子类型（请参阅跟踪票证#19744，#25659）。

I have a multisite WP so once I go through the blogs for some reasons in some blogs url_to_postid()works, in other blogs on the post of the same type it doesn't while get_page_by_path()works like charm. So I made it this way, which may be not perfect though:
我有一个多站点 WP，所以一旦我出于某些原因浏览了一些博客中的博客url_to_postid()，在相同类型的其他博客中，它不会get_page_by_path()像魅力一样工作。所以我这样做了，虽然这可能并不完美：
$parsed_url = wp_parse_url( $url ); // Parse URL
$slug = substr($parsed_url['path'], 1 ); // Trim slash in the beginning
$post_id = url_to_postid( $slug ); // Attempt to get post ID
if ( ! $post_id ) { // If it didn't work try to get it manually from DB
$post_query_result =
$wpdb->get_row("SELECT ID FROM {$wpdb->prefix}posts WHERE post_name = '{$slug}'");
$analog_id = (int) $post_query_result->ID;
}

you can try this one also:
你也可以试试这个：
$post = get_page_by_path('cat',OBJECT,'animal');
cat is the one you are looking for= the permalink; animal is the custom post type,
cat 是您正在寻找的那个=永久链接；动物是自定义帖子类型，

please use
请用
$postid = url_to_postid( $url );
to retrive the ID of an attachment.
检索附件的 ID。
It is required that the url provided be in the format of example.com/?attachment_id=Nand will not work with the full URL to get the id from the full URL.
要求提供的 url 格式为example.com/?attachment_id=N并且不能与完整 URL 一起使用以从完整 URL 获取 id。
