## Atom Authorization `Atom authorization` mainly solves such problems: `who` can perform `which actions` of atom data within `which data scope` ### Authorization Record Authorization of `atom action` for `atomClass`, such as the following authorization record: | Role | AtomClass | Atom Action | |----|----|----| | system | party | create | ### Data Scope of Authorization When authorizing, you can specify the data scope of the permission, such as the following authorization record: | Role | AtomClass | Atom Action | Data Scope | |----|----|----|----| | system | party | read | finance department | > The role `system` can only read `party` data of `finance department` ## Authorization Ways There are three ways of authorization: `Artificial Authorization`, `Initial Authorization`, `Test Authorization` The API methods for `initial authorization` and `test authorization` are as follows: ### addRoleRight `a-base/backend/src/config/middleware/adapter/role.js` ``` javascript async addRoleRight({ roleId, atomClassId, action, scope }) ``` | Name | Description | |----|----| | roleId | RoleId to be authorized | | atomClassId | Atom Class Id | | action | Atom Action Code | | scope | Data Scope | > scope supports the following values: > > * `0`: Can operate the atom data created by self > * `roleId`: Can operate the atom data created by users belonged to roleId and roleId’s child roles > * `roleIds`: Array of roleId ### addRoleRightBatch `a-base/backend/src/config/middleware/adapter/role.js` ``` javascript // const roleRights = [ // { roleName: 'cms-writer', action: 'create' }, // { roleName: 'cms-writer', action: 'write', scopeNames: 0 }, // { roleName: 'cms-writer', action: 'delete', scopeNames: 0 }, // { roleName: 'cms-writer', action: 'read', scopeNames: 'authenticated' }, // { roleName: 'cms-publisher', action: 'read', scopeNames: 'authenticated' }, // { roleName: 'cms-publisher', action: 'write', scopeNames: 'authenticated' }, // { roleName: 'cms-publisher', action: 'publish', scopeNames: 'authenticated' }, // { roleName: 'root', action: 'read', scopeNames: 'authenticated' }, // ]; async addRoleRightBatch({ module, atomClassName, roleRights }) ``` | Name | Description | |----|----| | module | module name. If it is empty, the current module name will be used | | atomClassName | atom class name | | roleRights | array of authorization records | ### For Example `src/suite-vendor/test-party/modules/test-party/backend/src/service/version.js` ``` javascript // add role rights const roleRights = [ { roleName: 'system', action: 'create' }, { roleName: 'system', action: 'write', scopeNames: 0 }, { roleName: 'system', action: 'delete', scopeNames: 0 }, { roleName: 'system', action: 'read', scopeNames: 'authenticated' }, { roleName: 'system', action: 'review', scopeNames: 'authenticated' }, ]; await this.ctx.meta.role.addRoleRightBatch({ atomClassName: 'party', roleRights }); ``` ## Rules of Authorization Checking Because atoms provide many features and states such as `draft`, `simple workflow` and `public access` will affect the checking rules of atom authorizations Rules of Authorization Checking corresponding to different states of atoms is as follows: | Atom Action | Draft | Simple Workflow | Public Access | Normal | |----|:---:|:---:|:---:|:---:| | create | \- | \- | \- | \- | | read | only the creator has permission | determine whether there is authorization for other actions. For example, if there is `write` permission, there must be `read` permission | no need to check | need to check | | write、delete | only the creator has permission | need to check | \- | need to check | | custom actions | \- | need to check | \- | need to check | > * `-`: not support > * `create`: only need to authorize on atom class, regardless of the atom data ### Draft Atom have two states: `draft` and `normal` In the `draft` state, only the creator can perform the actions of `write` and `delete` In the `normal` state, only authorized users can perform the corresponding authorized actions ### Public Access By default, atoms can only be queried if they are granted permission. CabloyJS also supports direct `public access` without permission. Just set the `public` of the atom class to `1` ### Simple Workflow At present, CabloyJS implements the `simple workflow` mechanism For example, we can design such a workflow: 1、The user creates a new article, which is in `draft` state, and can be read by self 2、The article submitted by the user cannot be accessed publicly at this time, but can be read by the users who have `review` permission 3、The article can only be accessed publicly after `reviewed` by users who have `review` permission ## Authorization Checking Authorization can be checked by `middleware` or `API` ### Check by Middleware CabloyJS uses the global middleware `right` to encapsulate the logic of authorization checking. It only needs to configure the corresponding middleware parameters on the API route `src/suite-vendor/test-party/modules/test-party/backend/src/routes.js` ``` javascript { method: 'post', path: 'test/atom/checkRightCreate', controller: testAtomRight, middlewares: 'test', meta: { right: { type: 'atom', action: 1 } }, }, { method: 'post', path: 'test/atom/checkRightRead', controller: testAtomRight, middlewares: 'test', meta: { right: { type: 'atom', action: 2 } }, }, { method: 'post', path: 'test/atom/checkRightWrite', controller: testAtomRight, middlewares: 'test', meta: { right: { type: 'atom', action: 3 } }, }, { method: 'post', path: 'test/atom/checkRightAction', controller: testAtomRight, middlewares: 'test', meta: { right: { type: 'atom', action: 101 } }, }, ``` | Name | Description | |----|----| | right | the global middleware `right`, which is enabled by default, only needs to configure parameters | | type | authorization type. here is `atom authorization` | | action | atom action code | ### Check by API `src/suite-vendor/test-party/modules/test-party/backend/src/controller/test/atom/all.js` ``` javascript // atomClass const atomClass = await this.ctx.meta.atomClass.get({ atomClassName: 'party' }); // userIds const userIds = this.ctx.cache.mem.get('userIds'); ``` #### action: create ``` javascript const checkRightCreates = [[ 'Tom', true ], [ 'Jimmy', true ], [ 'Smith', false ]]; for (const [ userName, right ] of checkRightCreates) { const res = await this.ctx.meta.atom.checkRightCreate({ atomClass, user: { id: userIds[userName] }, }); assert.equal(!!res, right, userName); } ``` #### action: read ``` javascript const checkRightReads = [[ 'Tom', partyKey.atomId, true ]]; for (const [ userName, atomId, right ] of checkRightReads) { const res = await this.ctx.meta.atom.checkRightRead({ atom: { id: atomId }, user: { id: userIds[userName] }, }); assert.equal(!!res, right, userName); } ``` #### action: write ``` javascript const checkRightWrites = [[ 'Tom', partyKey.atomId, true ], [ 'Tomson', partyKey.atomId, false ]]; for (const [ userName, atomId, right ] of checkRightWrites) { const res = await this.ctx.meta.atom.checkRightUpdate({ atom: { id: atomId, action: this.ctx.constant.module('a-base').atom.action.write }, user: { id: userIds[userName] }, }); assert.equal(!!res, right, userName); } ``` #### action: delete ``` javascript const checkRightDeletes = [[ 'Tom', partyKey.atomId, true ], [ 'Tomson', partyKey.atomId, false ]]; for (const [ userName, atomId, right ] of checkRightDeletes) { const res = await this.ctx.meta.atom.checkRightUpdate({ atom: { id: atomId, action: this.ctx.constant.module('a-base').atom.action.delete }, user: { id: userIds[userName] }, }); assert.equal(!!res, right, userName); } ``` #### custom actions ``` javascript // action: review(101) const checkRightActions_1 = [[ 'Tom', partyKey.atomId, false ], [ 'Jane', partyKey.atomId, true ]]; for (const [ userName, atomId, right ] of checkRightActions_1) { const res = await this.ctx.meta.atom.checkRightAction({ atom: { id: atomId, action: 101 }, user: { id: userIds[userName] }, }); assert.equal(!!res, right, userName); } ```
