我通过我的应用程序获取非授权错误woocommerce

Question

我在Ionic应用程序上使用woocommerce API 我尝试将应用程序与Wordpress连接出现错误 picture

已经阅读了发行API的文档 documentation foodmall

1）在this.service.currencies ....

中错误加载货币

loadCurrency() {
        let subscription: Subscription = this.service.currencies(window.localStorage.getItem(Constants.ADMIN_API_KEY)).subscribe(data => {
            let currency: Currency = data;
            window.localStorage.setItem(Constants.CURRENCY, JSON.stringify(currency));
            console.log('currency setup success');
        }, err => {
            console.log('currency setup error');
        });
        this.subscriptions.push(subscription);
    }

2）此.service.categories .....

中的错误加载类别

loadCategories() {
    let subscription: Subscription = this.service.categories(window.localStorage.getItem(Constants.ADMIN_API_KEY), String(this.pageCategory)).subscribe(data => {
        let categories: Array<Category> = data;
        if (categories.length == 0) {
            window.localStorage.setItem(Constants.PRODUCT_CATEGORIES, JSON.stringify(this.categoriesAll));
            console.log('categories setup success');
            this.events.publish('category:setup');
        } else {
            this.categoriesAll = this.categoriesAll.concat(categories);
            this.pageCategory++;
            this.loadCategories();
        }
    }, err => {
        console.log('loadCategories setup error');
    });
    this.subscriptions.push(subscription);
}

遵循类别的服务

    public categories(adminToken: string, pageNo: string): Observable<Array<Category>> {
    const myHeaders = new HttpHeaders({ 'Content-Type': 'application/json', 'Authorization': adminToken });
    return this.http
        .get<Array<Category>>(this.config.apiBase + 'wc/v2/products/categories/?per_page=20&order=desc&orderby=count&page=' + pageNo + '&_embed', { headers: myHeaders })
        .concatMap(data => {
            return Observable.of(data);
        });
}
