以下为 ​​HarmonyOS 5应用上架元数据自动化生成工具链​​的完整解决方案，包含从资源提取到合规检查的全流程代码实现：

---

1. 工具链架构

---

2. 核心模块实现

2.1 资源提取器（Python）

# extract_metadata.py
import json
import xml.etree.ElementTree as ET
from pathlib import Path

def extract_strings(res_dir: Path):
    strings = {}
    for lang_dir in res_dir.glob('*/element'):
        lang = lang_dir.parent.name
        strings[lang] = {}
        
        # 解析string.json
        with open(lang_dir / 'string.json') as f:
            data = json.load(f)
            for key, value in data.items():
                strings[lang][key] = value

        # 解析color/plural等
        # ...其他资源解析逻辑
    return strings

if __name__ == "__main__":
    res_dir = Path('./resources/base')
    metadata = extract_strings(res_dir)
    with open('output/app_strings.json', 'w') as f:
        json.dump(metadata, f, indent=2)

2.2 多语言转换（Node.js）

// translate.js
const { translate } = require('@hw/translation-sdk');
const fs = require('fs');

async function generateTranslations(baseLang = 'en') {
  const source = JSON.parse(fs.readFileSync('output/app_strings.json'));
  const targets = ['zh', 'es', 'fr', 'ja'];
  
  for (const lang of targets) {
    const translated = await translate({
      content: source[baseLang],
      from: baseLang,
      to: lang,
      glossary: 'tech' // 使用技术术语词库
    });
    
    fs.writeFileSync(
      `output/descriptions/${lang}/short.txt`,
      translated.app_description
    );
  }
}

generateTranslations();

---

3. 自动化合规检查

3.1 敏感词检测

// validate.ts
import { SensitiveWord } from '@hw/content-filter';
import fs from 'fs';

const filter = new SensitiveWord({
  categories: ['politics', 'porn', 'violence']
});

function checkDescriptions() {
  const langs = fs.readdirSync('output/descriptions');
  const errors: string[] = [];
  
  langs.forEach(lang => {
    const text = fs.readFileSync(`output/descriptions/${lang}/short.txt`, 'utf8');
    if (filter.hasSensitive(text)) {
      errors.push(`${lang}描述包含敏感词: ${filter.getLastMatches()}`);
    }
  });
  
  if (errors.length) throw new Error(errors.join('\n'));
}

checkDescriptions();

3.2 截图规范校验

# validate_screenshots.py
from PIL import Image
import os

def validate_screenshots(dir_path):
    requirements = {
        'phone': [(1080, 1920), (720, 1280)],
        'tablet': [(1920, 1200)]
    }
    
    for device_type, sizes in requirements.items():
        files = os.listdir(f'{dir_path}/{device_type}')
        for size in sizes:
            if not any(f.endswith(f'{size[0]}x{size[1]}.png') for f in files):
                raise ValueError(f'缺少{device_type} {size[0]}x{size[1]}尺寸截图')

validate_screenshots('assets/screenshots')

---

4. 元数据打包

4.1 生成AppGallery配置

// generate_agc_config.js
const fs = require('fs');
const manifest = JSON.parse(fs.readFileSync('config.json'));

const agcConfig = {
  appInfo: {
    packageName: manifest.package,
    versionName: manifest.versionName,
    category: getCategory(manifest.features) // 自动分类逻辑
  },
  descriptions: {},
  media: []
};

// 填充多语言描述
fs.readdirSync('output/descriptions').forEach(lang => {
  agcConfig.descriptions[lang] = {
    brief: fs.readFileSync(`output/descriptions/${lang}/short.txt`, 'utf8'),
    full: fs.readFileSync(`output/descriptions/${lang}/full.txt`, 'utf8')
  };
});

// 添加截图路径
fs.readdirSync('assets/screenshots').forEach(file => {
  agcConfig.media.push({
    type: file.endsWith('.mp4') ? 'video' : 'image',
    path: `assets/screenshots/${file}`,
    device: file.includes('_tab_') ? 'tablet' : 'phone'
  });
});

fs.writeFileSync('dist/agc_metadata.json', JSON.stringify(agcConfig, null, 2));

4.2 一键上传脚本

#!/bin/bash
# upload_to_agc.sh

# 1. 登录AGC
agc login --client-id $CLIENT_ID --client-secret $CLIENT_SECRET

# 2. 上传元数据
agc app upload-metadata \
  --file dist/agc_metadata.json \
  --project-id $PROJECT_ID

# 3. 提交审核
agc app submit \
  --app-id $APP_ID \
  --release-notes '自动化提交'

---

5. 集成到DevEco Studio

5.1 自定义Gradle任务

// build.gradle
task generateMetadata(type: Exec) {
    commandLine 'python', 'scripts/extract_metadata.py'
    doLast {
        println '元数据提取完成'
    }
}

task validateMetadata {
    dependsOn generateMetadata
    doLast {
        exec { commandLine 'node', 'scripts/validate.js' }
        exec { commandLine 'python', 'scripts/validate_screenshots.py' }
    }
}

task packageMetadata {
    dependsOn validateMetadata
    doLast {
        exec { commandLine 'node', 'scripts/generate_agc_config.js' }
    }
}

5.2 预提交钩子

#!/bin/sh
# pre-commit-hook.sh

# 运行元数据生成
./gradlew packageMetadata

# 检查是否有错误
if grep -q "ERROR" ./output/validation.log; then
  echo "存在元数据错误，请检查validation.log"
  exit 1
fi

6. 完整工作流

7. 关键检查清单

检查项	自动化实现	手动确认点
多语言覆盖	检查zh/en等必需语言存在	翻译准确性
截图尺寸	验证分辨率符合要求	截图内容合规
隐私政策引用	检测config.json中声明	政策内容更新
年龄分级	根据API使用自动分级	最终分级确认
敏感词	自动扫描描述文本	误报复核

---

8. 异常处理方案

8.1 自动修复示例

# auto_fix_screenshot.py
from PIL import Image

def resize_screenshot(input_path, output_path, target_size):
    img = Image.open(input_path)
    if img.size != target_size:
        img = img.resize(target_size, Image.LANCZOS)
        img.save(output_path)
        print(f'已调整尺寸: {input_path} -> {output_path}')

# 批量处理
resize_screenshot('screenshot.png', 'screenshot_1080x1920.png', (1080, 1920))

8.2 审核失败自动重试

// retry_submit.js
const { retry } = require('@hw/agc-api');

async function handleRejection(reason) {
  if (reason.includes('screenshot')) {
    await runScreenshotFix();
    return retrySubmit();
  }
}

function retrySubmit(maxAttempts = 3) {
  return retry(
    () => agc.submit(),
    { maxAttempts, delay: 5000 }
  );
}
