**警告:**这是[Alpha](https://about.gitlab.com/handbook/product/#alpha)功能,随时可能更改,恕不另行通知.版本历史
* 在 GitLab 13.0 中[引入](https://gitlab.com/groups/gitlab-org/-/epics/2587) .
* 它部署在功能标记后面,默认情况下处于禁用状态.
* 在 GitLab.com 上已禁用.
* 要在 GitLab 自管实例中使用它,请让 GitLab 管理员[启用它](#enable-or-disable-project-access-tokens) .
项目访问令牌的范围仅限于项目,可用于通过[GitLab API](../../../api/README.html#personalproject-access-tokens)进行身份验证.
您还可以将项目访问令牌与 Git 一起使用,以通过 HTTP 或 SSH 进行身份验证.
项目访问令牌在您定义的日期 UTC 午夜到期.
有关如何使用项目访问令牌对 API 进行身份验证的示例,请参见[API 文档中](../../../api/README.html#personalproject-access-tokens)的以下部分.
## Creating a project access token[](#creating-a-project-access-token "Permalink")
1. 登录到 GitLab.
2. 导航至您要为其创建访问令牌的项目.
3. 在里面 **在设置**菜单中,选择**访问令牌** .
4. 选择令牌的名称和可选的到期日期.
5. 选择[所需的范围](#limiting-scopes-of-a-project-access-token) .
6. 单击**创建项目访问令牌**按钮.
7. 将项目访问令牌保存在安全的地方. 离开或刷新页面后,将无法再次访问它.
## Project bot users[](#project-bot-users "Permalink")
对于创建的每个项目访问令牌,还将创建一个机器人用户,并将其添加到具有["维护者"级别权限](../../permissions.html#project-members-permissions)的项目中. 使用项目访问令牌进行的 API 调用将与相应的 bot 用户相关联.
这些用户将出现在" **成员"中,**但不能被修改. 此外,该漫游器用户无法添加到任何其他项目.
[吊销](#revoking-a-project-access-token)项目访问令牌后,该漫游器用户将被删除,所有记录都将被移动到用户名" Ghost User"的系统范围内的用户. 有关更多信息,请参见[关联记录](../../profile/account/delete_account.html#associated-records) .
## Revoking a project access token[](#revoking-a-project-access-token "Permalink")
您可以随时通过单击相应的" **撤消"**按钮来撤消任何项目访问令牌. **设置>访问令牌** .
## Limiting scopes of a project access token[](#limiting-scopes-of-a-project-access-token "Permalink")
可以使用一个或多个范围创建项目访问令牌,这些范围允许给定令牌可以执行各种操作. 下表描述了可用范围.
| Scope | Description |
| --- | --- |
| `api` | 授予对范围内的项目 API 的完全读取/写入访问权限. |
| `read_api` | 授予对范围内的项目 API 的读取权限. |
| `read_registry` | 如果项目是私有的并且需要授权,则允许对[容器注册表](../../packages/container_registry/index.html)图像的读取(拉). |
| `write_registry` | 允许对[容器注册表](../../packages/container_registry/index.html)进行写访问(推送). |
| `read_repository` | 允许对存储库进行只读访问(拉). |
| `write_repository` | 允许对存储库进行读写访问(拉,推). |
### Enable or disable project access tokens[](#enable-or-disable-project-access-tokens "Permalink")
项目访问令牌是[Alpha](https://about.gitlab.com/handbook/product/#alpha)功能,不建议用于生产环境. 它部署在**默认情况下禁用**的功能标志的后面. [有权访问 GitLab Rails 控制台的 GitLab 管理员](../../../administration/feature_flags.html)可以为您的实例启用它.
To enable it:
```
Feature.enable(:resource_access_token)
```
禁用它:
```
Feature.disable(:resource_access_token)
