因此，一开始可能会造成混淆.要使此工作正常进行，您需要在本地代理您的提取.这是您可以执行的操作:

So this can be a bit confusing in the beginning. To get this working you need to proxy your fetches locally. Here's how you can do that:

在/posts/index.json.js中:

let contents;

export function get(req, res) {
    const posts = fetch('do stuff here to fetch')

    contents = JSON.stringify(posts);

    res.writeHead(200, {
        'Content-Type': 'application/json'
    });

    res.end(contents);
}

在您实际的路线组件/posts/index.svelte中:

And in your actual route component /posts/index.svelte:

<script context="module">
    export async function preload({ params, query }) {
        return this.fetch(`index.json`).then(r => r.json()).then(posts => {
            return { posts };
        });
    }
</script>

<script>
export let posts;
</script>

官方 Svelte网站使用此方法获取帖子(从本地文件而不是使用访存).您可能会从中得到一些启发.

The official Svelte website uses this approach to get posts (from a local file rather than using fetch though). You can probably get some inspiration from that.

值得一提的是，preload()函数既被提供给服务器，也被提供给前端，因此您不应在其中放置API密钥.

It is worth mentioning that the preload() function is shipped both to the server and the front-end so you should not put API keys there.
