如何获得 WP-API 类别的帖子列表？

Question

应该很容易，但是在WP-API docs里没找到。

Answer 1

找到了，有点[隐藏][1]

使用类别名称： /posts?categories=1

试试这个。

Answer 2

对于类别名称，应添加两个过滤器，如下所示：

add_filter( "rest_post_query", function( $args, $request){
                if ( isset( $request['category_name']) && !empty($request['category_name'] ) ) {
                    $args['category_name'] = $request['category_name'];
                }
                return $args;
            }, 10, 2);


add_filter( "rest_post_collection_params", function($query_params, $post_type){
                $query_params[ 'category_name' ] = array(           
                    'description' => __( 'Category name.' ),
                    'type'        => 'string',
                    'readonly'    => true,
                );
                return $query_params;
            }, 10, 2);

Answer 3

这个例子 url 对我有用... https://yourdomain.com/?rest_route=/wp/v2/posts&categories=99

Answer 4

此问题与 this other question here from the forum

重复

http://example.com/wp-json/wp/v2/posts?categories=20,30

以上将从category 20 OR category 30

return posts

我已经使用自定义 post 类型进行了测试，它也能完美运行

Answer 5

这段代码对我有用

Add to your function.php

function rest_filter_by_custom_taxonomy( $args, $request ) {

if ( isset($request['category_slug']) )
{
    $category_slug = sanitize_text_field($request['category_slug']);
    $args['tax_query'] = [
        [
            'taxonomy' => 'category',
            'field'    => 'slug',
            'terms'    => $category_slug,
        ]
    ];
}

return $args;

 }
 add_filter('rest_post_query', 'rest_filter_by_custom_taxonomy', 10, 3);

EX: /wp-json/wp/v2/posts?category_slug=news
