当我向http://localhost/wordpress/wp-json/wp/v2/posts/?_embed&categories=${categoryId}&per_page=${state.perPage}

我得到以下结果

但正如您所看到的，没有特色的\\ U媒体。我是否对featured\\u media有误解？我的帖子里有一幅你在content.rendered

$url = \'url of your wordpress website\';
function Json_Data_Decoder($query){     
    global $url;
    $json = file_get_contents($url.\'/wp-json/wp/v2/\'. $query);
    $data = json_decode($json);
    return $data;
}
function Get_Media($post_media){
    global $url;
    $json = file_get_contents($url.\'/wp-json/wp/v2/media?include=\'.$post_media);
    $medias = json_decode($json);
    $featured_image = $medias[0]->media_details->sizes->medium->source_url;
    return $featured_image;
}

$posts = Json_Data_Decoder(\'posts\');
foreach ($posts as $post){
    
    // get media 
    $post_media = $post->featured_media;
    $featured_image = Get_media($post_media);
    
    echo 
    \'<article class="post image">
            <img src="\'.
                $featured_image .
            \'">
    </article>\';
