Question

wordpress中的所有图片都会自动调整大小并保存在上传文件夹中，如下所示：

sample_product_image-100x100.png
sample_product_image-150x150.png
sample_product_image-180x113.png
sample_product_image-300x189.png
...
sample_product_image-555x349.png
sample_product_image-600x378.png
sample_product_image.png (original large file)

为了加快加载速度我需要在休息api中使用较小尺寸的产品图像：

sample_product_image-300x189.png

但是woocommerce rest api只是发给我原始最大的文件（sample_product_image.png）：

"images": [
            {
                "id": 7291,
                "date_created": "2018-06-12T03:17:03",
                "date_created_gmt": "2018-06-11T13:47:03",
                "date_modified": "2018-06-12T03:17:03",
                "date_modified_gmt": "2018-06-11T13:47:03",
                "src": "http://example.com/wp-content/uploads/2018/06/sample_product_image.png",
                "name": "sample_product_image",
                "alt": "",
                "position": 0
            },

如何在wc rest api中获取较小的图片网址？

btw我发现this plugin用于wordpress rest api，这对于woocommerce不起作用。

Answer 1

找到了解决方案here。只需要将此过滤器添加到主题的function.php

中

function prepare_product_images($response, $post, $request) {
    global $_wp_additional_image_sizes;

    if (empty($response->data)) {
        return $response;
    }

    foreach ($response->data['images'] as $key => $image) {
        $image_urls = [];
        foreach ($_wp_additional_image_sizes as $size => $value) {
            $image_info = wp_get_attachment_image_src($image['id'], $size);
            $response->data['images'][$key][$size] = $image_info[0];
        }
    }
    return $response;

}

add_filter("woocommerce_rest_prepare_product_object", "prepare_product_images", 10, 3);

此外，如果您只需要1个特殊尺寸，则可以删除第二个foreach并手动将$size初始化为'thumbnail'，'medium'，'medium_large'或'large'
