# 在 HTTP 服务器上配置 TLS

设置 `tls` 键以配置 TLS。`key` 和 `cert` 都是必需的。`key` 应该是你的私钥内容；`cert` 应该是你颁发的证书内容。使用 [`Bun.file()`](/runtime/file-io#reading-files-bun-file) 读取内容。

```ts server.ts icon="https://mintcdn.com/bun-zhcndoc/cnUTwgMuf4cCrwC-/icons/typescript.svg?fit=max&auto=format&n=cnUTwgMuf4cCrwC-&q=85&s=e7767043c9e885c34f2d6c8fe2a95217" theme={"theme":{"light":"github-light","dark":"dracula"}}
const server = Bun.serve({
  fetch: request => new Response("Welcome to Bun!"),
  tls: {
    cert: Bun.file("cert.pem"),
    key: Bun.file("key.pem"),
  },
});
```

***

默认情况下，Bun 信任 Mozilla 精选的知名根证书列表。要覆盖此列表，可以传递一个证书数组作为 `ca`。

const server = Bun.serve({
  fetch: request => new Response("Welcome to Bun!"),
  tls: {
    cert: Bun.file("cert.pem"),
    key: Bun.file("key.pem"),
    ca: [Bun.file("ca1.pem"), Bun.file("ca2.pem")],
  },
});
```
