Bundles

捆绑包是 Capgo 中的核心更新包。每个捆绑包都包含构成应用程序内容的 Web 资源（HTML、CSS、JS）。捆绑包 API 允许您管理这些更新包，包括列出和删除它们。

了解捆绑包

捆绑包代表应用程序 Web 内容的特定捆绑包（版本），包括：

捆绑包（版本）：捆绑包的语义版本号
校验和：用于验证包完整性的唯一哈希值
存储信息：有关捆绑包存储位置和方式的详细信息
本机要求：最低本机应用程序版本要求
元数据：创建时间、所有权和其他跟踪信息

手动创建捆绑包（不带 CLI）

下面介绍了如何在不使用 Capgo CLI 的情况下手动创建和上传捆绑包：

第 1 步：构建您的应用程序

首先，构建应用程序的网络资产：

npm run build

步骤 2：使用与 Capgo CLI 相同的包创建捆绑包 Zip

重要：使用 Capgo CLI 内部使用的完全相同的 JavaScript 包来确保兼容性。

安装所需的软件包

npm install adm-zip @tomasklaen/checksum

使用 JavaScript 创建 Zip 包（与 Capgo CLI 相同）

注意：在下面的示例中，version 指的是 API 使用的包（版本）名称。

const fs = require('node:fs');
const path = require('node:path');
const os = require('node:os');
const AdmZip = require('adm-zip');
const { checksum: getChecksum } = require('@tomasklaen/checksum');

// Exact same implementation as Capgo CLI
function zipFileUnix(filePath) {
  const zip = new AdmZip();
  zip.addLocalFolder(filePath);
  return zip.toBuffer();
}

async function zipFileWindows(filePath) {
  console.log('Zipping file windows mode');
  const zip = new AdmZip();

  const addToZip = (folderPath, zipPath) => {
    const items = fs.readdirSync(folderPath);

    for (const item of items) {
      const itemPath = path.join(folderPath, item);
      const stats = fs.statSync(itemPath);

      if (stats.isFile()) {
        const fileContent = fs.readFileSync(itemPath);
        zip.addFile(path.join(zipPath, item).split(path.sep).join('/'), fileContent);
      } else if (stats.isDirectory()) {
        addToZip(itemPath, path.join(zipPath, item));
      }
    }
  };

  addToZip(filePath, '');
  return zip.toBuffer();
}

// Main zipFile function (exact same logic as CLI)
async function zipFile(filePath) {
  if (os.platform() === 'win32') {
    return zipFileWindows(filePath);
  } else {
    return zipFileUnix(filePath);
  }
}

async function createBundle(inputPath, outputPath, version) {
  // Create zip using exact same method as Capgo CLI
  const zipped = await zipFile(inputPath);

  // Write to file
  fs.writeFileSync(outputPath, zipped);

  // Calculate checksum using exact same package as CLI
  const checksum = await getChecksum(zipped, 'sha256');

  return {
    filename: path.basename(outputPath),
    version: version,
    size: zipped.length,
    checksum: checksum
  };
}

// Usage
async function main() {
  try {
    const result = await createBundle('./dist', './my-app-1.2.3.zip', '1.2.3');
    console.log('Bundle info:', JSON.stringify(result, null, 2));
  } catch (error) {
    console.error('Error creating bundle:', error);
  }
}

main();

步骤 3：使用与 CLI 相同的包计算 SHA256 校验和

const fs = require('node:fs');
const { checksum: getChecksum } = require('@tomasklaen/checksum');

async function calculateChecksum(filePath) {
  const fileBuffer = fs.readFileSync(filePath);
  // Use exact same package and method as Capgo CLI
  const checksum = await getChecksum(fileBuffer, 'sha256');
  return checksum;
}

// Usage
async function main() {
  const checksum = await calculateChecksum('./my-app-1.2.3.zip');
  console.log('Checksum:', checksum);
}

main();

步骤 4：将捆绑包上传到您的存储

将您的 zip 文件上传到任何可通过网络访问的存储：

# Example: Upload to your server via scp
scp my-app-1.2.3.zip user@your-server.com:/var/www/bundles/

# Example: Upload to S3 using AWS CLI
aws s3 cp my-app-1.2.3.zip s3://your-bucket/bundles/

# Example: Upload via curl to a custom endpoint
curl -X POST https://your-storage-api.com/upload \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -F "file=@my-app-1.2.3.zip"

重要：您的捆绑包必须可通过 HTTPS URL 公开访问（无需身份验证）。 Capgo 的服务器需要从此 URL 下载捆绑包。

有效公共 URL 的示例：

https://your-storage.com/bundles/my-app-1.2.3.zip
https://github.com/username/repo/releases/download/v1.2.3/bundle.zip
https://cdn.jsdelivr.net/gh/username/repo@v1.2.3/dist.zip

步骤 5：使用 Capgo API 注册捆绑包

使用直接 API 调用向 Capgo 注册外部包：

async function registerWithCapgo(appId, version, bundleUrl, checksum, apiKey) {
  const fetch = require('node-fetch');

  // Create bundle (version)
  const response = await fetch('https://api.capgo.app/bundle/', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'authorization': apiKey
    },
    body: JSON.stringify({
      app_id: appId,
      version: version,
      external_url: bundleUrl,
      checksum: checksum
    })
  });

  if (!response.ok) {
    throw new Error(`Failed to create bundle: ${response.statusText}`);
  }

  const data = await response.json();
  console.log('Bundle created:', data);

  return data;
}

API 参数

参数	描述	必填
`app_id`	您的应用程序标识符	是的
`version`	捆绑包（版本）语义版本（例如“1.2.3”）	是的
`external_url`	可公开访问可下载捆绑包的 HTTPS URL（无需身份验证）	是的
`checksum`	zip 文件的 SHA256 校验和	是的

捆绑包结构要求

您的捆绑包 zip 必须遵循以下要求：

根索引文件：根级别必须有 index.html
Capacitor 集成：必须在您的应用代码中调用 notifyAppReady()
资产路径：对所有资产使用相对路径

有效的包结构

bundle.zip
├── index.html
├── assets/
│   ├── app.js
│   └── styles.css
└── images/

完整的手动工作流程示例

用于压缩、校验和上传到 Capgo 的简单 Node.js 脚本：

const fs = require('node:fs');
const os = require('node:os');
const AdmZip = require('adm-zip');
const { checksum: getChecksum } = require('@tomasklaen/checksum');
const fetch = require('node-fetch');

async function deployToCapgo() {
  const APP_ID = 'com.example.app';
  const VERSION = '1.2.3';
  const BUNDLE_URL = 'https://your-storage.com/bundles/app-1.2.3.zip';
  const API_KEY = process.env.CAPGO_API_KEY;

  // 1. Create zip (same as Capgo CLI)
  const zip = new AdmZip();
  zip.addLocalFolder('./dist');
  const zipped = zip.toBuffer();

  // 2. Calculate checksum (same as Capgo CLI)
  const checksum = await getChecksum(zipped, 'sha256');
  console.log('Checksum:', checksum);

  // 3. Upload to your storage (replace with your upload logic)
  // fs.writeFileSync('./bundle.zip', zipped);
  // ... upload bundle.zip to your storage ...

  // 4. Register with Capgo API
  const response = await fetch('https://api.capgo.app/bundle/', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'authorization': API_KEY
    },
    body: JSON.stringify({
      app_id: APP_ID,
      version: VERSION,
      external_url: BUNDLE_URL,
      checksum: checksum
    })
  });

  if (!response.ok) {
    throw new Error(`Failed: ${response.statusText}`);
  }

  console.log('Bundle registered with Capgo!');
}

deployToCapgo().catch(console.error);

安装依赖项：

npm install adm-zip @tomasklaen/checksum node-fetch

校验和验证

JavaScript 校验和计算（与 Capgo CLI 相同）

使用与 Capgo CLI 内部使用完全相同的包和方法：

const fs = require('node:fs');
const { checksum: getChecksum } = require('@tomasklaen/checksum');

async function calculateChecksum(filePath) {
  const fileBuffer = fs.readFileSync(filePath);
  // Use exact same package and method as Capgo CLI
  const checksum = await getChecksum(fileBuffer, 'sha256');
  return checksum;
}

// Verify checksum matches
async function verifyChecksum(filePath, expectedChecksum) {
  const actualChecksum = await calculateChecksum(filePath);
  const isValid = actualChecksum === expectedChecksum;

  console.log(`File: ${filePath}`);
  console.log(`Expected: ${expectedChecksum}`);
  console.log(`Actual:   ${actualChecksum}`);
  console.log(`Valid:    ${isValid}`);

  return isValid;
}

// Usage
async function main() {
  const bundleChecksum = await calculateChecksum('./my-app-1.2.3.zip');
  console.log('SHA256 Checksum:', bundleChecksum);
}

main();
```### 校验和重要性

- **捆绑包完整性**：确保捆绑包在传输过程中没有损坏
- **API 验证**：Capgo 在接受捆绑包之前验证校验和
- **插件验证**：移动插件在应用更新之前验证校验和

## 最佳实践

1. **捆绑包（版本）管理**：一致地使用语义版本控制
2. **存储优化**：定期删除未使用的捆绑包
3. **捆绑包（版本）兼容性**：设置适当的最低本机版本要求
4. **备份策略**：维护关键捆绑包（版本）的备份
