创建新的基于角色的访问控制 (RBAC) 条件

¥Create new Role-Based Access Control (RBAC) conditions

基于角色的访问控制 (RBAC) 是一种限制某些用户访问的方法。在 Strapi 应用中，管理面板的用户是管理员。他们的角色和权限是在管理面板中配置。

¥Role-Based Access Control (RBAC) is an approach to restricting access to some users. In a Strapi application, users of the admin panel are administrators. Their roles and permissions are configured in the admin panel.

声明新条件

¥Declaring new conditions

将单个条件声明为对象，将多个条件声明为对象数组。每个条件对象可以有 5 个可能的属性：

¥Declare a single condition as an object, and multiple conditions as an array of objects. Each condition object can have 5 possible properties:

displayName（字符串）：管理面板中显示的条件名称，
¥displayName (string): the condition name as shown in the admin panel,
name（字符串）：条件名称，烤肉串格式，
¥name (string): the condition name, kebab-cased,
category（字符串，可选）：条件可分为可用类别在管理面板中；如果未定义，则条件将出现在 "默认" 类别下，
¥category (string, optional): conditions can be grouped into categories available in the admin panel; if undefined, the condition will appear under the "Default" category,
plugin（字符串，可选）：如果条件是由插件创建的，则应该是插件的名称，短横线格式（例如 content-manager），
¥plugin (string, optional): if the condition is created by a plugin, should be the plugin's name, kebab-cased (e.g content-manager),
handler：用于验证条件的函数（参见使用条件处理程序）
¥handler: a function used to verify the condition (see using the condition handler)

在 ./src/index.js 中找到的全局 bootstrap 功能中声明并注册条件（参见注册条件）。

¥Declare and register conditions in the global bootstrap function found in ./src/index.js (see Registering conditions).

✏️ 注意

条件 name 属性充当其命名空间内的唯一 ID，如果定义了 plugin 属性，则为插件，或者根命名空间。

¥The condition name property acts as a unique id within its namespace, that is either the plugin if the plugin property is defined, or the root namespace.

使用条件处理程序

¥Using the condition handler

条件可以应用于任何权限，条件 handler 用于验证条件。handler 是一个返回查询对象或布尔值的函数。

¥A condition can be applied to any permission, and the condition handler is used to verify the condition. The handler is a function returning a query object or a boolean value.

查询对象可用于验证你读取、创建、更新、删除或发布的实体的条件。他们使用 sift.js 库，但仅支持以下运算符：

¥Query objects are useful to verify conditions on the entities you read, create, update, delete or publish. They use the sift.js library, but only with the following supported operators:

$or
$and
$eq
$eqi
$ne
$in
$nin
$lt
$lte
$gt
$gte
$exists
$elemMatch

条件 handler 可以是同步或异步函数：

¥The condition handler can be a synchronous or asynchronous function that:

接收发出请求的经过身份验证的用户，
¥receives the authenticated user making the request,
并返回 true、false 或查询对象。
¥and returns true, false, or a query object.

返回 true 或 false 对于验证外部条件或经过身份验证的用户的条件很有用。例如，仅当服务器时间为下午 5 点时才允许访问管理面板中的页面的条件可以使用此处理程序：

¥Returning true or false is useful to verify an external condition or a condition on the authenticated user. For instance, a condition that allows access to a page in the admin panel only if server time is 5pm could use this handler:

handler: () => new Date().getHours() === 17;

handler 函数接收经过身份验证的用户，因此它可以验证用户的条件：

¥The handler function receives the authenticated user, so it can verify conditions on the user:

const condition = {


  displayName: 'Email address from strapi.io',
  name: 'email-strapi-dot-io',
  async handler(user) {
    return user.email.includes('@strapi.io');
  },
};

为了更精细的控制，handler 函数还可以返回一个查询对象：

¥For more granular control, the handler function can also return a query object:

const condition = {


  displayName: 'price greater than 50',
  name: 'price-gt-50',
  async handler(user) {
    return { price: { $gt: 50 } };
  },
};

注册条件

¥Registering conditions

要在管理面板中可用，应在 ./src/index 中找到的全局 bootstrap 功能中声明和注册条件。使用 conditionProvider.register() 方法注册单个条件：

¥To be available in the admin panel, conditions should be declared and registered in the global bootstrap function found in ./src/index. Register a single condition with the conditionProvider.register() method:

JavaScript
TypeScript

./src/index.js

module.exports = async () => {
  await strapi.admin.services.permission.conditionProvider.register({
    displayName: 'Billing amount under 10K',
    name: 'billing-amount-under-10k',
    plugin: 'admin',
    handler: { amount: { $lt: 10000 } },
  });
};

./src/index.ts

export default async () => {
  await strapi.admin.services.permission.conditionProvider.register({
    displayName: 'Billing amount under 10K',
    name: 'billing-amount-under-10k',
    plugin: 'admin',
    handler: { amount: { $lt: 10000 } },
  });
};

要注册多个条件（定义为条件对象数组），请使用 conditionProvider.registerMany()：

¥To register multiple conditions, defined as an array of condition objects, use conditionProvider.registerMany():

JavaScript
TypeScript

./src/index.js



const conditions = [


  {
    displayName: "Entity has same name as user",
    name: "same-name-as-user",
    plugin: "name of a plugin if created in a plugin",
    handler: (user) => {
      return { name: user.name };
    },
  },
  {
    displayName: "Email address from strapi.io",
    name: "email-strapi-dot-io",
    async handler(user) {
      return user.email.includes('@strapi.io');
    },
  }
];

module.exports = {
  async bootstrap(/*{ strapi }*/) {
  // do your boostrap

    await strapi.admin.services.permission.conditionProvider.registerMany(conditions);
  },
};

// path: ./src/index.ts



const conditions = [


  {
    displayName: "Entity has same name as user",
    name: "same-name-as-user",
    plugin: "name of a plugin if created in a plugin"
    handler: (user) => {
      return { name: user.name };
    },
  },
  {
    displayName: "Email address from strapi.io",
    name: "email-strapi-dot-io",
    async handler(user) {
      return user.email.includes('@strapi.io');
    },
  }
];

export default async () => {
  // do your boostrap

  await strapi.admin.services.permission.conditionProvider.registerMany(conditions);
};
