我有一个自定义的帖子类型，叫做pronews. 我在注册了show_in_rest 已启用。我正在使用WordPress 5.5。

然后我有了这个代码：

export const ProPost  = wp.api.models.Post.extend( {
    urlRoot: wpApiSettings.root + \'wp/v2/pronews\',
    defaults: {
        type: \'pronews\',
    },
} );
export const ProPosts = wp.api.collections.Posts.extend( {
    url: wpApiSettings.root + \'wp/v2/pronews\',
    model: ProPost,
} );

const post = new ProPost( {id: 2454} );

console.log( post );
console.log( \'post urlRoot:\' + post.urlRoot );
console.log( \'post url:\' + post.url );

post.fetch().then( ( response ) => {
    console.log( response )
}, ( why ) => {
    console.log( why.responseJSON.code )
} );

// Double check that the endpoint is functionnal
fetch( wpApiSettings.root + \'wp/v2/pronews/2454\' )
    .then( blob => blob.json() )
    .then( ( response ) => {
        console.log( response.id );
    } );

在控制台中，我首先得到：

{…}
​_changing: false
​_pending: false
​_previousAttributes: Object { type: "pronews", id: 2454 }
​attributes: Object { type: "pronews", id: 2454 }
​changed: Object {  }
​cid: "c3"
​id: 2454
​<prototype>: Object { urlRoot: "https://localhost/wp-json/wp/v2/pronews", defaults: {…}, constructor: i()
 }
ProNews.js:17:9

post urlRoot:https://localhost/wp-json/wp/v2/pronews ProNews.js:18:9
post url:function(){var e=a.get("apiRoot")+a.get("versionString")+("me"===i?"users/me":i);return _.isUndefined(this.get("id"))||(e+="/"+this.get("id")),e} ProNews.js:19:9

但是主干API的请求是错误的urlRoot :

XHRGET https://localhost/wp-json/wp/v2/posts/2454 [HTTP/1.1 404 Not Found 340ms]
rest_post_invalid_id

对于调试，第二个HTTP请求的结果使用window.fetch, 显示自定义帖子类型的终结点存在并且可以正常工作：

XHRGET https://localhost/wp-json/wp/v2/pronews/2454 [HTTP/1.1 200 OK 587ms]
2454

// Access one model (a single post). ID is required.
const post = new wp.api.models.Pronews( { id: 57 } );

// Access a collection (multiple models/posts).
const posts = new wp.api.collections.Pronews();
