serverActions

用于在 Next.js 应用中配置服务器操作行为的选项。

¥Options for configuring Server Actions behavior in your Next.js application.

allowedOrigins

可以从中调用服务器操作的额外安全源域的列表。Next.js 将服务器操作请求的来源与主机域进行比较，确保它们匹配以防止 CSRF 攻击。如果未提供，则仅允许相同来源。

¥A list of extra safe origin domains from which Server Actions can be invoked. Next.js compares the origin of a Server Action request with the host domain, ensuring they match to prevent CSRF attacks. If not provided, only the same origin is allowed.

/** @type {import('next').NextConfig} */

module.exports = {
  experimental: {
    serverActions: {
      allowedOrigins: ['my-proxy.com', '*.my-proxy.com'],
    },
  },
}

bodySizeLimit

默认情况下，发送给 Server Action 的请求体的最大大小为 1MB，以防止解析大量数据时消耗过多的服务器资源，以及潜在的 DDoS 攻击。

¥By default, the maximum size of the request body sent to a Server Action is 1MB, to prevent the consumption of excessive server resources in parsing large amounts of data, as well as potential DDoS attacks.

但是，你可以使用 serverActions.bodySizeLimit 选项配置此限制。它可以采用字节数或字节支持的任何字符串格式，例如 1000、'500kb' 或 '3mb'。

¥However, you can configure this limit using the serverActions.bodySizeLimit option. It can take the number of bytes or any string format supported by bytes, for example 1000, '500kb' or '3mb'.

/** @type {import('next').NextConfig} */

module.exports = {
  experimental: {
    serverActions: {
      bodySizeLimit: '2mb',
    },
  },
}

启用服务器操作 (v13)

¥Enabling Server Actions (v13)

服务器操作成为 Next.js 14 中的一项稳定功能，并且默认启用。但是，如果你使用的是早期版本的 Next.js，则可以通过将 experimental.serverActions 设置为 true 来启用它们。

¥Server Actions became a stable feature in Next.js 14, and are enabled by default. However, if you are using an earlier version of Next.js, you can enable them by setting experimental.serverActions to true.

/** @type {import('next').NextConfig} */
const config = {
  experimental: {
    serverActions: true,
  },
}

module.exports = config
