分配别名并提升到生产

了解部署 URL 以及如何设置别名。

部署

¥Deployments

部署到 EAS Hosting 是不可变的。每个部署都可以通过由预览子域名和部署 ID 组成的唯一部署 URL 进行访问。

¥Deployments to EAS Hosting are immutable. Each deployment is accessible via a unique deployment URL consisting of the preview subdomain name and the deployment ID.

预览子域名

¥Preview subdomain name

要为项目激活 EAS 托管，你需要选择一个预览子域名。你可以通过 expo.dev 网站上项目的托管部分执行此操作。或者，当你使用 EAS CLI 创建第一个部署时，系统会提示你选择预览子域。

¥To activate EAS Hosting for a project, you'll need to choose a preview subdomain name. You can do this via the Hosting section of your project on the expo.dev website. Alternatively, you'll be prompted to choose a preview subdomain when you create your first deployment using the EAS CLI.

预览和生产 URL

¥Preview and production URLs

预览子域名是用于应用预览 URL 的前缀。例如，如果你选择 my-app 作为预览子域名，你的预览 URL 将是：https://my-app--or1170q9ix.expo.app/，你的生产 URL 将是：https://my-app.expo.app/。

¥A preview subdomain name is a prefix used for the preview URL of your app. For example, if you choose my-app as the preview subdomain name, your preview URL would be: https://my-app--or1170q9ix.expo.app/, and your production URL would be: https://my-app.expo.app/.

部署 ID

¥Deployment ID

每个部署都可使用唯一部署 ID 进行识别。此 ID 可以自定义，但默认情况下将是一串随机的字母和数字。

¥Each deployment is identifiable using a unique deployment ID. This ID can be customized but will be a random string of letters and numbers by default.

部署不可变。一旦部署，它们就无法更改，并且始终可以使用其部署 ID 进行访问和识别。

¥Deployments are immutable. Once they are deployed, they cannot be changed and will always remain accessible and identifiable using their deployment ID.

别名

¥Aliases

别名是用于创建部署自定义 URL 的用户定义值。

¥Aliases are user-defined values used for creating custom URLs for deployments.

要进行部署并将其分配给别名，请使用 --alias 选项：

¥To make a deployment and assign it to an alias, use the --alias option:

上述命令将创建一个部署，其中 https://my-app--or1170q9ix.expo.app/ 具有标准 URL，https://my-app--hello.expo.app/ 具有别名。

¥The above command will create a deployment with both a standard URL at https://my-app--or1170q9ix.expo.app/ and an alias at https://my-app--hello.expo.app/.

每个项目的别名都是唯一的。如果你选择的别名已在使用中，它将被重新分配给新的部署。

¥Aliases are unique per project. If you choose an alias that was already in use, it will get re-assigned to the new deployment.

单个部署可以有多个别名。还可以使用 --id 选项将别名分配给现有部署：

¥A single deployment can have multiple aliases. Aliases can also be assigned to an existing deployment by using the --id option:

在上面的命令中，my-id 是预览 URL 中的 ID。

¥In the above command, the my-id is the ID in the preview URL.

别名可以有任意名称。例如，如果你想创建一个暂存环境，你可以创建一个名为 staging 的别名并为其分配一个部署。

¥Aliases can have arbitrary names. For example, if you want to create a staging environment, you may create an alias called staging and assign a deployment to it.

生产别名

¥Production alias

如果你的预览子域名是 my-app，则你的生产 URL 将为 https://my-app.expo.app/。

¥If your preview subdomain name is my-app, your production URL will be https://my-app.expo.app/.

与其他别名类似，可以使用 --prod 选项将部署提升到生产：

¥Similar to other aliases, a deployment can be promoted to production using --prod option:

也可以使用其部署 ID 和 --id 选项将现有部署提升到生产环境：

¥Existing deployment can also be promoted to production using its deployment ID with the --id option:

术语

¥Terminology

在以下示例中，my-app 被选为预览子域名：

¥In the following example, my-app is selected as the preview subdomain name:

• https://my-app--or1170q9ix.expo.app/：预览 URL，它是唯一的，并且你的部署可用。

  ¥https://my-app--or1170q9ix.expo.app/ : Preview URL, which is unique and where your deployment is available.

  • my-app：预览子域名。与你的项目绑定的全局唯一前缀。

    ¥my-app: Preview subdomain name. Globally unique prefix tied to your project.

  • or1170q9ix：部署 ID，此部署独有。

    ¥or1170q9ix: Deployment ID, which is unique to this deployment.

• https://my-app--hello.expo.app/：带有别名的部署 URL。

  ¥https://my-app--hello.expo.app/: A deployment URL with an alias.

  • hello：用户定义的别名。

    ¥hello: User-defined alias.

• https://my-app.expo.app/：生产部署 URL。

  ¥https://my-app.expo.app/: Production deployment URL.

常见问题

¥Common questions

EAS Hosting 是否提供专用 IP 地址？

¥Does EAS Hosting provide dedicated IP addresses?

不，EAS Hosting 使用 SNI（服务器名称指示），这意味着 IP 地址是共享的，而不是专用于单个项目。

¥No, EAS Hosting uses SNI (Server Name Indication), which means that IP addresses are shared and are not dedicated to a single project.
