2. 核心模块实现

2.1 工程转换器

// project-converter.ets
import fs from '@ohos.file.fs';
import path from '@ohos.path';

class CordovaToHarmonyConverter {
  static async convert(projectDir: string): Promise<void> {
    const config = this._readConfig(projectDir);
    await this._generateHarmonyProject(config);
  }

  private static _readConfig(projectDir: string): ProjectConfig {
    const configPath = path.join(projectDir, 'config.xml');
    return XMLParser.parse(fs.readTextSync(configPath));
  }

  private static _generateHarmonyProject(config: ProjectConfig): void {
    const template = this._getTemplate('default');
    const replacements = {
      '{{bundleName}}': config.packageName,
      '{{version}}': config.version
    };
    
    TemplateEngine.render(
      template,
      replacements,
      path.join(projectDir, 'harmony')
    );
  }
}

2.2 依赖适配器

// dependency-adapter.ets
class CordovaDependencyAdapter {
  static adapt(plugin: CordovaPlugin): HarmonyDependency[] {
    return plugin.nativeDependencies.map(dep => {
      return {
        name: this._mapPackageName(dep.android),
        version: dep.version,
        harmonyEquivalent: this._findHarmonyEquivalent(dep)
      };
    });
  }

  private static _mapPackageName(androidPackage: string): string {
    return androidPackage.replace('com.android.', '@ohos.');
  }
}

3. 构建系统集成

3.1 Gradle任务包装器

// cordova-build.gradle.kts
tasks.register("cordovaBuild") {
    group = "cordova"
    dependsOn("assembleHap")
    
    doLast {
        exec {
            commandLine(
                "ohpm", "run", "cordova-build",
                "--project=${projectDir.path}",
                "--platform=harmony"
            )
        }
    }
}

3.2 HAP打包增强

// hap-packager.ets
class CordovaHapPackager {
  static async package(projectDir: string): Promise<void> {
    await this._copyWebAssets(projectDir);
    await this._generateNativeBridge();
    await this._signPackage();
  }

  private static async _copyWebAssets(projectDir: string): Promise<void> {
    const wwwPath = path.join(projectDir, 'www');
    const assetsPath = path.join(projectDir, 'entry', 'src', 'main', 'resources');
    await fs.copy(wwwPath, assetsPath);
  }
}

4. 插件系统扩展

4.1 Cordova插件转换

// plugin-transformer.ets
class CordovaPluginTransformer {
  static transform(pluginDir: string): HarmonyPlugin {
    const pluginXml = this._parsePluginXml(pluginDir);
    return {
      id: pluginXml.id,
      hooks: this._convertHooks(pluginXml.hooks),
      nativeModules: this._convertNativeCode(pluginDir)
    };
  }

  private static _convertNativeCode(pluginDir: string): NativeModule[] {
    return fs.readDirSync(path.join(pluginDir, 'src', 'android'))
      .filter(file => file.endsWith('.java'))
      .map(file => JavaToArkTS.convert(file));
  }
}

4.2 钩子命令适配

// hook-adapter.ets
class CordovaHookAdapter {
  private static hookMap = new Map<string, string>([
    ['before_build', 'preBuild'],
    ['after_plugin_add', 'postInstall']
  ]);

  static convert(hook: CordovaHook): HarmonyHook {
    return {
      name: this.hookMap.get(hook.name) || hook.name,
      script: this._rewriteScript(hook.script)
    };
  }

  private static _rewriteScript(script: string): string {
    return script
      .replace('cordova/', 'harmony/')
      .replace('platforms/android', 'platforms/harmony');
  }
}

5. 开发工具集成

5.1 DevEco菜单扩展

// CordovaMenuExtension.java
public class CordovaMenuExtension implements DevEcoMenuProvider {
  @Override
  public List<ActionGroup> getActionGroups() {
    return Arrays.asList(
      new ActionGroup(
        "Cordova",
        Arrays.asList(
          new Action("Convert Project", this::convertProject),
          new Action("Add Platform", this::addPlatform)
        )
      )
    );
  }

  private void convertProject(Project project) {
    new CordovaProjectConverter(project).run();
  }
}

5.2 工程向导

// project-wizard.ets
@Component
struct CordovaProjectWizard {
  @State projectName: string = '';
  @State packageName: string = 'com.example';
  @State targetDevices: DeviceType[] = ['phone', 'tablet'];

  build() {
    Column() {
      TextInput({ placeholder: '项目名称' })
        .onChange(val => this.projectName = val)
      
      DeviceTypeCheckboxes({
        selected: this.targetDevices,
        onChange: (devices) => this.targetDevices = devices
      })
      
      Button('创建')
        .onClick(() => this._createProject())
    }
  }

  private _createProject(): void {
    ProjectGenerator.generate({
      name: this.projectName,
      package: this.packageName,
      devices: this.targetDevices
    });
  }
}

6. 构建流程定制

6.1 自定义构建任务

// build-task.ets
class CordovaBuildTask implements BuildTask {
  async execute(): Promise<void> {
    await this._prepareEnvironment();
    await this._runCordovaHooks('before_build');
    await this._compileWebAssets();
    await this._buildHarmonyPackage();
    await this._runCordovaHooks('after_build');
  }

  private async _compileWebAssets(): Promise<void> {
    await exec('webpack --config webpack.harmony.config.js');
  }
}

6.2 多平台构建

// multi-builder.ets
class MultiPlatformBuilder {
  static async build(platforms: string[]): Promise<void> {
    await ParallelRunner.run(
      platforms.map(platform => () => this._buildPlatform(platform))
    );
  }

  private static async _buildPlatform(platform: string): Promise<void> {
    const builder = platform === 'harmony' ? 
      new HarmonyBuilder() : 
      new CordovaPlatformBuilder(platform);
    await builder.build();
  }
}

7. 调试支持

7.1 混合调试桥

// hybrid-debugger.ets
class CordovaHybridDebugger {
  static attach(webView: WebView): void {
    DebugSession.start({
      type: 'hybrid',
      webView: webView,
      nativeDebugger: new ArkTSDebugger(),
      webDebugger: new ChromeDebugger()
    });
  }

  static setBreakpoints(breakpoints: Breakpoint[]): void {
    breakpoints.forEach(bp => {
      if (bp.isNative) {
        ArkTSDebugger.setBreakpoint(bp);
      } else {
        ChromeDebugger.setBreakpoint(bp);
      }
    });
  }
}

7.2 日志拦截器

// log-interceptor.ets
class CordovaLogInterceptor {
  private static originalConsole = window.console;

  static install(): void {
    window.console = new Proxy(console, {
      get(target, prop) {
        if (['log', 'warn', 'error'].includes(prop)) {
          return (...args) => {
            LogBridge.sendToNative(prop, args);
            target[prop](...args);
          };
        }
        return target[prop];
      }
    });
  }
}

8. 生产环境配置

8.1 构建配置文件

// cordova-build.json
{
  "harmony": {
    "minAPIVersion": 5,
    "targetAPIVersion": 5,
    "buildTools": {
      "webpack": true,
      "arkCompiler": true
    },
    "signing": {
      "autoSign": true,
      "storeFile": "release.p12"
    }
  }
}

8.2 插件白名单

// plugin-whitelist.ets
class PluginWhitelist {
  private static allowedPlugins = [
    'cordova-plugin-camera',
    'cordova-plugin-file'
  ];

  static isAllowed(pluginId: string): boolean {
    return this.allowedPlugins.includes(pluginId);
  }

  static getRecommendedAlternatives(): PluginAlternative[] {
    return [
      {
        cordova: 'cordova-plugin-geolocation',
        harmony: '@ohos.geolocation'
      }
    ];
  }
}

9. 完整工作流示例

9.1 添加HarmonyOS平台

# 通过插件CLI
cordova platform add harmony --via=devEco-plugin

9.2 构建运行命令

// cordova-cli.ets
class CordovaCLI {
  static async runCommand(cmd: string, args: string[]): Promise<void> {
    switch (cmd) {
      case 'build':
        await this._build(args);
        break;
      case 'run':
        await this._run(args);
        break;
    }
  }

  private static async _build(args: string[]): Promise<void> {
    const platform = args.includes('--harmony') ? 'harmony' : 'android';
    await MultiPlatformBuilder.build([platform]);
  }
}
