微信小游戏 (Cocos) 快速开始

准备工作​

在开始之前，请确保您已完成以下准备：

  1. 开通云开发环境：开通云开发环境
  2. 开发工具：下载并安装 微信开发者工具
  3. 小程序账号：注册微信小程序，获取小程序的 AppID

更多详情请参考：微信小游戏 (Cocos) 完整文档

添加 CloudBase AI 开发插件​

可选：如果你使用 AI 编程助手（如 Cursor、Claude Code、CodeBuddy 等）进行开发，建议先完成本步骤，让 AI 具备 CloudBase 开发能力。

复制 AI Prompt 粘贴到 AI IDE​

在 AI 对话中输入：

帮我把 CloudBase 接好，按下面做：
1. 打开 https://docs.cloudbase.net/skill.md，按说明完成接入。
2. 接入完成后告诉我，并建议最相关的下一步。

使用 Skills 开发​

对 AI 说：

使用 CloudBase Skills：在微信小游戏 (Cocos)中集成云开发，包括数据库和云存储功能

Skills 使用文档 →

也可以手动安装 CloudBase Skills：

npx skills add tencentcloudbase/cloudbase-skills -y

安装 SDK​

@cloudbase/js-sdk 配合 @cloudbase/adapter-cocos_native 可以让您在 Cocos 项目中访问 CloudBase 服务和资源。

npm​

npm i @cloudbase/js-sdk @cloudbase/adapter-cocos_native

yarn​

yarn add @cloudbase/js-sdk @cloudbase/adapter-cocos_native

pnpm​

pnpm add @cloudbase/js-sdk @cloudbase/adapter-cocos_native

初始化 SDK​

新增如下代码到您的 Cocos 项目

scripts/services/CloudbaseService.js​

import cloudbaseSDK from "@cloudbase/js-sdk";
import adapter from "@cloudbase/adapter-cocos_native";

// 注册适配器
cloudbaseSDK.useAdapters(adapter);

const cloudbase = cloudbaseSDK.init({
  // 环境 ID
  env: "{%ENV_ID%}",
  // 地域
  region: "{%REGION%}",
  // 匿名访问令牌
  accessKey: "{%PUBLISHABLE_KEY%}"
});

export default cloudbase;

身份认证​

使用 短信验证码注册 请先前往 身份认证/登录方式 开启 短信验证码

调用方式：

import cloudbase from "./services/CloudbaseService";

const auth = cloudbase.auth();

// 发送验证码
const res = await auth.getVerification({ phone_number: phone });
const verificationId = res.verification_id;

// 验证验证码
const verifyRes = await auth.verify({
  verification_id: verificationId,
  verification_code: code
});

// 注册
await auth.signUp({
  phone_number: `+86 ${phone}`,
  verification_code: code,
  verification_token: verifyRes.verification_token,
  name: `user_${phone.slice(-4)}`,
  password: "admin@123"
});

完整示例：

import { _decorator, Component, Node, EditBox, Label } from 'cc';
import cloudbase from './services/CloudbaseService';

const { ccclass, property } = _decorator;

@ccclass('SmsRegister')
export class SmsRegister extends Component {
  @property(EditBox)
  phoneInput: EditBox = null;

  @property(EditBox)
  codeInput: EditBox = null;

  @property(Label)
  messageLabel: Label = null;

  private verificationId: string = '';

  // 发送验证码
  async onSendCodeButtonClick() {
    const phone = this.phoneInput.string;
    if (!phone) {
      this.messageLabel.string = '请输入手机号';
      return;
    }

    try {
      const auth = cloudbase.auth();
      const res = await auth.getVerification({ phone_number: phone });
      this.verificationId = res.verification_id;
      this.messageLabel.string = '验证码已发送！';
    } catch (error) {
      this.messageLabel.string = `发送失败: ${error.message}`;
    }
  }

  // 注册
  async onRegisterButtonClick() {
    const phone = this.phoneInput.string;
    const code = this.codeInput.string;

    if (!this.verificationId || !code) {
      this.messageLabel.string = '请先发送验证码';
      return;
    }

    try {
      const auth = cloudbase.auth();
      // 验证验证码
      const verifyRes = await auth.verify({
        verification_id: this.verificationId,
        verification_code: code,
      });
      // 注册（如用户已存在则自动登录）
      await auth.signUp({
        phone_number: `+86 ${phone}`,
        verification_code: code,
        verification_token: verifyRes.verification_token,
        name: `user_${phone.slice(-4)}`,
        password: "admin@123"
      });
      this.messageLabel.string = '注册成功！';
      console.log('注册成功');
    } catch (error) {
      this.messageLabel.string = `注册失败: ${error.message}`;
      console.error('注册失败：', error);
    }
  }
}

文档型数据库​

调用方式：

import cloudbase from "./services/CloudbaseService";

const db = cloudbase.database();
const res = await db.collection("{%TABLE_NAME%}").limit(10).get();

完整示例：

import { _decorator, Component, Node, Label } from 'cc';
import cloudbase from './services/CloudbaseService';

const { ccclass, property } = _decorator;

@ccclass('QueryDocData')
export class QueryDocData extends Component {
  @property(Label)
  resultLabel: Label = null;

  async onLoad() {
    try {
      const db = cloudbase.database();
      const res = await db.collection("{%TABLE_NAME%}").limit(10).get();

      this.resultLabel.string = `查询成功：${JSON.stringify(res.data)}`;
      console.log('查询结果：', res.data);
    } catch (error) {
      this.resultLabel.string = `查询失败: ${error.message}`;
      console.error('查询失败：', error);
    }
  }
}

云存储​

调用方式：

import cloudbase from "./services/CloudbaseService";

const res = await cloudbase.uploadFile({
  cloudPath: `images/${Date.now()}.png`,
  filePath: filePath
});

完整示例：

import { _decorator, Component, Node, Label } from 'cc';
import cloudbase from './services/CloudbaseService';

const { ccclass, property } = _decorator;

@ccclass('UploadFile')
export class UploadFile extends Component {
  @property(Label)
  resultLabel: Label = null;

  async onUploadButtonClick() {
    try {
      // 注意：实际使用中需要从用户选择或游戏资源中获取文件路径
      const filePath = 'path/to/your/file.png';
      const cloudPath = `images/${Date.now()}-${Math.random()}.png`;

      const res = await cloudbase.uploadFile({
        cloudPath: cloudPath,
        filePath: filePath
      });

      this.resultLabel.string = `上传成功！文件ID: ${res.fileID}`;
      console.log('上传成功：', res);
    } catch (error) {

      this.statusLabel.string = '请输入主题';
      return;
    }

    this.statusLabel.string = '生成中...';
    this.resultLabel.string = '';

    try {
      const ai = cloudbase.ai();
      const model = ai.createModel("cloudbase");

      // 确保已登录
      const loginState = await cloudbase.auth().getLoginState();
      if (!loginState) {
        await cloudbase.auth().signInAnonymously();
      }

      const res = await model.streamText({
        model: "hy3",
