使用 Images 的自定义域

如需快速上手，请点击下方按钮。

这会在你的 GitHub 账户中创建仓库，并将应用部署到 Cloudflare Workers。

要从自定义域提供图片：

在 Cloudflare 仪表板中，前往 Workers & Pages 页面。
Go to Workers & Pages ↗
选择 Create application（创建应用程序） > Workers > Create Worker（创建 Worker） 并创建 Worker。
在 Worker 中，选择 Quick edit（快速编辑） 并粘贴以下代码。

export default {
	async fetch(request) {
		// You can find this in the dashboard, it should look something like this: ZWd9g1K7eljCn_KDTu_MWA
		const accountHash = "";

		const { pathname } = new URL(request.url);

		// A request to something like cdn.example.com/83eb7b2-5392-4565-b69e-aff66acddd00/public
		// will fetch "https://imagedelivery.net/<accountHash>/83eb7b2-5392-4565-b69e-aff66acddd00/public"

		return fetch(`https://imagedelivery.net/${accountHash}${pathname}`);
	},
};

export default {
	async fetch(request): Promise<Response> {
		// You can find this in the dashboard, it should look something like this: ZWd9g1K7eljCn_KDTu_MWA
		const accountHash = "";

		const { pathname } = new URL(request.url);

		// A request to something like cdn.example.com/83eb7b2-5392-4565-b69e-aff66acddd00/public
		// will fetch "https://imagedelivery.net/<accountHash>/83eb7b2-5392-4565-b69e-aff66acddd00/public"

		return fetch(`https://imagedelivery.net/${accountHash}${pathname}`);
	},
} satisfies ExportedHandler;

import { Hono } from 'hono';

interface Env {
  // You can store your account hash as a binding variable
  ACCOUNT_HASH?: string;
}

const app = new Hono<{ Bindings: Env }>();

app.get('*', async (c) => {
  // You can find this in the dashboard, it should look something like this: ZWd9g1K7eljCn_KDTu_MWA
  // Either get it from environment or hardcode it here
  const accountHash = c.env.ACCOUNT_HASH || "";

  const url = new URL(c.req.url);

  // A request to something like cdn.example.com/83eb7b2-5392-4565-b69e-aff66acddd00/public
  // will fetch "https://imagedelivery.net/<accountHash>/83eb7b2-5392-4565-b69e-aff66acddd00/public"

  return fetch(`https://imagedelivery.net/${accountHash}${url.pathname}`);
});

export default app;

from workers import WorkerEntrypoint
from js import URL, fetch

class Default(WorkerEntrypoint):
    async def fetch(self, request):
        # You can find this in the dashboard, it should look something like this: ZWd9g1K7eljCn_KDTu_MWA
        account_hash = ""
        url = URL.new(request.url)

        # A request to something like cdn.example.com/83eb7b2-5392-4565-b69e-aff66acddd00/public
        # will fetch "https://imagedelivery.net/<accountHash>/83eb7b2-5392-4565-b69e-aff66acddd00/public"
        return fetch(f'https://imagedelivery.net/{account_hash}{url.pathname}')

另一种从自定义域提供图片的方式是使用 cdn-cgi/imagedelivery 前缀路径，该路径用于触发 cdn-cgi 图片代理。

以下示例中，主机名是与 Image 位于同一账户下的 Cloudflare 代理域，后跟前缀路径以及可在 Cloudflare 仪表板的 Images 中找到的 <ACCOUNT_HASH>、<IMAGE_ID> 和 <VARIANT_NAME>。

https://example.com/cdn-cgi/imagedelivery/<ACCOUNT_HASH>/<IMAGE_ID>/<VARIANT_NAME>
