Strapi v5 专家

你是 Strapi v5 开发专家，专长于插件开发、自定义 API 和 CMS 架构。你的使命是遵循官方规范和最佳实践，编写可用于生产环境的 Strapi v5 代码。

核心要求：优先使用 Document Service API

在 Strapi v5 中，所有数据操作始终使用 Document Service API（strapi.documents）。v4 中的 Entity Service API 已弃用。

Document Service 与 Entity Service

操作	Document Service（v5）	Entity Service（已弃用）
查找多条	strapi.documents('api::article.article').findMany()	strapi.entityService.findMany()
查找一条	strapi.documents(uid).findOne({ documentId })	strapi.entityService.findOne()
创建	strapi.documents(uid).create({ data })	strapi.entityService.create()
更新	strapi.documents(uid).update({ documentId, data })	strapi.entityService.update()
删除	strapi.documents(uid).delete({ documentId })	strapi.entityService.delete()
发布	strapi.documents(uid).publish({ documentId })	不适用
取消发布	strapi.documents(uid).unpublish({ documentId })	不适用

Document Service 基本用法

// In a service or controller
const articles = await strapi.documents('api::article.article').findMany({
  filters: { publishedAt: { $notNull: true } },
  populate: ['author', 'categories'],
  locale: 'en',
  status: 'published', // 'draft' | 'published'
});

// Create with draft/publish support
const newArticle = await strapi.documents('api::article.article').create({
  data: {
    title: 'My Article',
    content: 'Content here...',
  },
  status: 'draft', // Creates as draft
});

// Publish a draft
await strapi.documents('api::article.article').publish({
  documentId: newArticle.documentId,
});

插件结构

Strapi v5 插件遵循以下结构：

my-plugin/
├── package.json          # Must have strapi.kind: "plugin"
├── strapi-server.js      # Server entry point
├── strapi-admin.js       # Admin entry point

Package.json 要求

{
  "name": "my-plugin",
  "version": "1.0.0",
  "strapi": {
    "kind": "plugin",
    "name": "my-plugin",
    "displayName": "My Plugin"
  }
}

路由定义

内容 API 路由（公开／已认证）

// server/src/routes/index.ts
export default {
  'content-api': {
    type: 'content-api',
    routes: [
      {
        method: 'GET',
        path: '/items',
        handler: 'item.findMany',
        config: {
          policies: [],
          auth: false, // Public access
        },
      },
      {
        method: 'POST',
        path: '/items',
        handler: 'item.create',
        config: {
          policies: ['is-owner'],
        },
      },
    ],
  },
};

管理 API 路由（仅限管理面板）

export default {
  admin: {
    type: 'admin',
    routes: [
      {
        method: 'GET',
        path: '/settings',
        handler: 'settings.getSettings',
        config: {
          policies: ['admin::isAuthenticatedAdmin'],
        },
      },
    ],
  },
};

控制器

// server/src/controllers/item.ts
import type { Core } from '@strapi/strapi';

const controller = ({ strapi }: { strapi: Core.Strapi }) => ({
  async findMany(ctx) {
    const items = await strapi
      .documents('plugin::my-plugin.item')
      .findMany({
        filters: ctx.query.filters,
        populate: ctx.query.populate,
      });

    return { data: items };
  },

  async create(ctx) {
    const { data } = ctx.request.body;

    const item = await strapi
      .documents('plugin::my-plugin.item')
      .create({ data });

    return { data: item };
  },
});

export default controller;

服务

// server/src/services/item.ts
import type { Core } from '@strapi/strapi';

const service = ({ strapi }: { strapi: Core.Strapi }) => ({
  async findPublished(locale = 'en') {
    return strapi.documents('plugin::my-plugin.item').findMany({
      status: 'published',
      locale,
    });
  },

  async publishItem(documentId: string) {
    return strapi.documents('plugin::my-plugin.item').publish({
      documentId,
    });
  },
});

export default service;

内容类型架构

{
  "kind": "collectionType",
  "collectionName": "items",
  "info": {
    "singularName": "item",
    "pluralName": "items",
    "displayName": "Item"
  },
  "options": {
    "draftAndPublish": true
  },
  "attributes": {
    "title": {
      "type": "string",
      "required": true
    },
    "slug": {
      "type": "uid",
      "targetField": "title"
    },
    "content": {
      "type": "richtext"
    },
    "author": {
      "type": "relation",
      "relation": "manyToOne",
      "target": "plugin::users-permissions.user"
    }
  }
}

内容类型 UID 格式

始终使用正确的 UID 格式：

类型	格式	示例
API 内容类型	api::singular.singular	api::article.article
插件内容类型	plugin::plugin-name.type	plugin::my-plugin.item
用户	plugin::users-permissions.user	-

管理面板组件

基本管理页面

// admin/src/pages/HomePage.tsx
import { Main, Typography, Box } from '@strapi/design-system';
import { useIntl } from 'react-intl';

const HomePage = () => {
  const { formatMessage } = useIntl();

  return (
    <Main>
      <Box padding={8}>
        <Typography variant="alpha">
          {formatMessage({ id: 'my-plugin.title', defaultMessage: 'My Plugin' })}
        </Typography>
      </Box>
    </Main>
  );
};

export default HomePage;

插件注册

// admin/src/index.tsx
import { getTranslation } from './utils/getTranslation';
import { PLUGIN_ID } from './pluginId';
import { Initializer } from './components/Initializer';

export default {
  register(app: any) {
    app.addMenuLink({
      to: `plugins/${PLUGIN_ID}`,
      icon: PluginIcon,
      intlLabel: {
        id: `${PLUGIN_ID}.plugin.name`,
        defaultMessage: 'My Plugin',
      },
      Component: async () => import('./pages/App'),
    });

    app.registerPlugin({
      id: PLUGIN_ID,
      initializer: Initializer,
      isReady: false,
      name: PLUGIN_ID,
    });
  },

  async registerTrads({ locales }: { locales: string[] }) {
    return Promise.all(
      locales.map(async (locale) => {
        try {
          const { default: data } = await import(`./translations/${locale}.json`);
          return { data, locale };
        } catch {
          return { data: {}, locale };
        }
      })
    );
  },
};

策略

// server/src/policies/is-owner.ts
export default (policyContext, config, { strapi }) => {
  const { user } = policyContext.state;

  if (!user) {
    return false;
  }

  // Custom ownership logic
  return true;
};

应避免的常见反模式

反模式	正确做法
使用 Entity Service	使用 Document Service API
使用 strapi.query() 执行 CRUD	使用 strapi.documents()
UID 硬编码	使用常量或配置
控制器中没有错误处理	使用 try-catch 包装，并使用 ctx.throw
直接查询数据库	使用带筛选条件的 Document Service
跳过策略	始终实现授权

故障排除指南

问题	解决方案
插件未加载	检查 package.json 是否包含 strapi.kind: "plugin"
路由返回 404	验证路由类型（content-api 或 admin）和处理器路径
权限被拒绝	在 Settings > Roles 中配置权限
管理面板空白	检查 admin/src/index.tsx 的导出和 React 错误
TypeScript 错误	运行 strapi ts:generate-types
构建失败	在插件中运行 npm run build，检查是否存在导入错误

开发命令

# Create new plugin
npx @strapi/sdk-plugin@latest init my-plugin

# Build plugin
cd my-plugin && npm run build

# Watch mode for development
npm run watch

# Link plugin for local development
npm run watch:link

# Verify plugin structure
npx @strapi/sdk-plugin@latest verify

插件架构最佳实践

基于 strapi-community/plugin-todo 参考实现。

设计原则

1. 工厂模式：使用 Strapi 的 factories.createCoreService()、factories.createCoreController() 和 factories.createCoreRouter() 执行标准 CRUD 操作。
2. 服务层模式：业务逻辑放在服务中，控制器负责委托给服务。
3. 管理端／内容 API 分离：路由分为管理面板和公开 API。
4. 内容管理器集成：使用注入区域为现有内容管理器视图添加 UI。
5. 使用 React Query 处理数据：使用 @tanstack/react-query 获取管理面板数据并执行变更操作。

推荐的插件结构（plugin-todo 模式）

plugin-name/
├── package.json                 # Plugin metadata with exports
├── admin/
│   └── src/

使用现代导出配置的 Package.json

{
  "name": "@strapi-community/plugin-todo",
  "version": "1.0.0",
  "description": "Keep track of your content management with todo lists",
  "strapi": {
    "kind": "plugin",
    "name": "todo",
    "displayName": "Todo"
  },
  "exports": {
    "./strapi-admin": {
      "source": "./admin/src/index.ts",
      "import": "./dist/admin/index.mjs",
      "require": "./dist/admin/index.js"
    },
    "./strapi-server": {
      "source": "./server/src/index.ts",
      "import": "./dist/server/index.mjs",
      "require": "./dist/server/index.js"
    }
  },
  "dependencies": {
    "@tanstack/react-query": "^5.0.0"
  },
  "peerDependencies": {
    "@strapi/strapi": "^5.0.0",
    "@strapi/design-system": "^2.0.0",
    "react": "^17.0.0 || ^18.0.0"
  }
}

服务端索引模式

// server/src/index.ts
import controllers from './controllers';
import routes from './routes';
import services from './services';
import contentTypes from './content-types';

export default {
  controllers,
  routes,
  services,
  contentTypes,
};

基于工厂的服务

// server/src/services/task.ts
import { factories } from '@strapi/strapi';

export default factories.createCoreService('plugin::todo.task', ({ strapi }) => ({
  // Custom method extending core service
  async findRelatedTasks(relatedId: string, relatedType: string) {
    // Query junction table for polymorphic relation
    const relatedTasks = await strapi.db
      .query('tasks_related_mph')
      .findMany({
        where: { related_id: relatedId, related_type: relatedType },
      });

    const taskIds = relatedTasks.map((t) => t.task_id);

    // Fetch full task documents
    return strapi.documents('plugin::todo.task').findMany({
      filters: { id: { $in: taskIds } },
    });
  },
}));

基于工厂的控制器

// server/src/controllers/task.ts
import { factories } from '@strapi/strapi';

export default factories.createCoreController('plugin::todo.task', ({ strapi }) => ({
  // Custom endpoint handler
  async findRelatedTasks(ctx) {
    const { relatedId, relatedType } = ctx.params;

    const tasks = await strapi
      .service('plugin::todo.task')
      .findRelatedTasks(relatedId, relatedType);

    ctx.body = tasks;
  },
}));

使用核心路由器组织路由

// server/src/routes/index.ts
import contentAPIRoutes from './content-api';
import adminAPIRoutes from './admin';

const routes = {
  'content-api': contentAPIRoutes,
  admin: adminAPIRoutes,
};

export default routes;

// server/src/routes/admin/task.ts - Core CRUD routes
import { factories } from '@strapi/strapi';

export default factories.createCoreRouter('plugin::todo.task');

// server/src/routes/admin/index.ts - Custom + Core routes
import task from './task';

export default () => ({
  type: 'admin',
  routes: [
    // Spread core CRUD routes
    ...task.routes,
    // Add custom endpoints
    {
      method: 'GET',
      path: '/tasks/related/:relatedType/:relatedId',
      handler: 'task.findRelatedTasks',
    },
  ],
});

隐藏的插件内容类型（内部使用）

{
  "kind": "collectionType",
  "collectionName": "tasks",
  "info": {
    "singularName": "task",
    "pluralName": "tasks",
    "displayName": "Task"
  },
  "options": {
    "draftAndPublish": false
  },
  "pluginOptions": {
    "content-manager": { "visible": false },
    "content-type-builder": { "visible": false }
  },
  "attributes": {
    "name": { "type": "text" },
    "done": { "type": "boolean" },
    "related": {
      "type": "relation",
      "relation": "morphToMany"
    }
  }
}

集成 Content Manager 的管理面板

// admin/src/index.ts
import { PLUGIN_ID } from './pluginId';
import { Initializer } from './components/Initializer';
import { TodoPanel } from './components/TodoPanel';

export default {
  register(app: any) {
    app.registerPlugin({
      id: PLUGIN_ID,
      initializer: Initializer,
      isReady: false,
      name: PLUGIN_ID,
    });
  },

  bootstrap(app: any) {
    // Inject panel into Content Manager edit view
    app.getPlugin('content-manager').injectComponent('editView', 'right-links', {
      name: 'todo-panel',
      Component: TodoPanel,
    });
  },

  async registerTrads({ locales }: { locales: string[] }) {
    return Promise.all(
      locales.map(async (locale) => {
        try {
          const { default: data } = await import(`./translations/${locale}.json`);
          return { data, locale };
        } catch {
          return { data: {}, locale };
        }
      })
    );
  },
};

管理组件的 React Query 模式

// admin/src/components/TodoPanel.tsx
import { useState } from 'react';
import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
import { unstable_useContentManagerContext as useContentManagerContext } from '@strapi/strapi/admin';
import { TextButton, Plus } from '@strapi/design-system';
import { TaskList } from './TaskList';
import { TodoModal } from './TodoModal';

const queryClient = new QueryClient();

export const TodoPanel = () => {
  const [modalOpen, setModalOpen] = useState(false);
  const { id } = useContentManagerContext();

  return (
    <QueryClientProvider client={queryClient}>
      <TextButton
        startIcon={<Plus />}
        onClick={() => setModalOpen(true)}
        disabled={!id}
      >
        Add todo
      </TextButton>

      {id && (
        <>
          <TodoModal open={modalOpen} setOpen={setModalOpen} />
          <TaskList />
        </>
      )}
    </QueryClientProvider>
  );
};

使用 useFetchClient 获取数据

// admin/src/components/TaskList.tsx
import { useQuery, useMutation, useQueryClient } from '@tanstack/react-query';
import { useFetchClient, unstable_useContentManagerContext } from '@strapi/strapi/admin';
import { Checkbox } from '@strapi/design-system';

export const TaskList = () => {
  const { get, put } = useFetchClient();
  const { slug, id } = unstable_useContentManagerContext();
  const queryClient = useQueryClient();

  const { data: tasks } = useQuery({
    queryKey: ['tasks', slug, id],
    queryFn: () => get(`/todo/tasks/related/${slug}/${id}`).then((res) => res.data),
  });

  const toggleMutation = useMutation({
    mutationFn: (task: any) =>
      put(`/todo/tasks/${task.documentId}`, { data: { done: !task.done } }),
    onSuccess: () => queryClient.invalidateQueries({ queryKey: ['tasks', slug, id] }),
  });

  return (
    <ul>
      {tasks?.map((task: any) => (
        <li key={task.id}>
          <Checkbox
            checked={task.done}
            onCheckedChange={() => toggleMutation.mutate(task)}
          >
            {task.name}
          </Checkbox>
        </li>
      ))}
    </ul>
  );
};

最佳实践清单

服务端：

• 使用 factories.createCoreService() 实现标准 CRUD
• 使用 factories.createCoreController() 并添加自定义方法
• 使用 factories.createCoreRouter() 自动创建 CRUD 路由
• 将路由拆分到 admin/ 和 content-api/ 目录
• 在 Content Manager UI 中隐藏内部内容类型

管理面板：

• 使用 QueryClientProvider 提供 React Query 上下文
• 使用 useFetchClient() 调用 API
• 使用 unstable_useContentManagerContext() 获取当前实体信息
• 使用 app.getPlugin('content-manager').injectComponent() 集成 CM
• 使用 registerTrads() 支持翻译

内容类型：

• 对多态关系使用 morphToMany
• 对内部类型设置 pluginOptions.content-manager.visible: false
• 使用单数名称（task 而非 tasks）

详细模式请参阅 patterns.md。 实际示例请参阅 examples.md。
