前言

自定义产物名称在鸿蒙应用开发中，当前有两种方式。一种是在build-profile.json5配置文件中修改artifactName属性，来改变最终的产物名称。参考：

{
  "products": [
    {
      "name": "default",
      "signingConfig": "default",
      "bundleName": "com.example.myapplication",
      "output": {
        "artifactName": "Test-1.0.0"
      }
    }
  ]
}

另外一种就是今天要介绍的动态方式，动态方式是通过修改应用打包编译流程实现更改产物名称。

如何动态生成编译构建产物HAP、HAR和APP的名称

1. 更改HAP包产物名称，编辑HAP所在的模块中的hvigorfile.ts。

import { hvigor } from '@ohos/hvigor';
import { hapTasks, OhosAppContext, OhosHapContext, OhosPluginId } from '@ohos/hvigor-ohos-plugin';

const appContext = hvigor.getRootNode().getContext(OhosPluginId.OHOS_APP_PLUGIN) as OhosAppContext;
const appJsonOpt = appContext.getAppJsonOpt();
const versionName = appJsonOpt['app']['versionName'];

hvigor.afterNodeEvaluate(node => {
  const hapContext = node.getContext(OhosPluginId.OHOS_HAP_PLUGIN) as OhosHapContext;
  if (hapContext && hapContext.getBuildProfileOpt) {
    const buildProfile = hapContext.getBuildProfileOpt();
    const targets = buildProfile.targets;
    targets.forEach((target) => {
      if (target.name === 'default') {
        target['output'] = {
          "artifactName": "Test-" + appContext.getBuildMode() + '-' + versionName + '_' + getTime(),
        };
      }
    })
    hapContext.setBuildProfileOpt(buildProfile);
  }
});

function getTime(): string {
  let date = new Date();
  let year = date.getFullYear();
  let month = (date.getMonth() + 1).toString().padStart(2, '0');
  let day = date.getDate().toString().padStart(2, '0');
  let hours = date.getHours().toString().padStart(2, '0');
  let minutes = date.getMinutes().toString().padStart(2, '0');
  return `${year}${month}${day}${hours}${minutes}`;
}

export default {
  system: hapTasks, /* Built-in plugin of Hvigor. It cannot be modified. */
  plugins: []       /* Custom plugin to extend the functionality of Hvigor. */
}

2. 更改HAR包名称，编辑HAR所在的模块中的hvigorfile.ts。

import { harTasks,OhosPluginId  } from '@ohos/hvigor-ohos-plugin';
import { hvigor } from '@ohos/hvigor'


hvigor.afterNodeEvaluate((hvigorNode)=>{
  const context = hvigorNode.getContext(OhosPluginId.OHOS_HAR_PLUGIN)
  if (context && context.getBuildProfileOpt) {
    const buildProfile = context.getBuildProfileOpt();
    const targets = buildProfile.targets
    for (const target of targets) {
      if (target.name === 'default') {
        target.output={
          "artifactName": 'Test'
        }
      }
    }
    context.setBuildProfileOpt(buildProfile);
  }
})


export default {
  system: harTasks,  /* Built-in plugin of Hvigor. It cannot be modified. */
  plugins:[]         /* Custom plugin to extend the functionality of Hvigor. */
}

3. 更改APP包名称，编辑工程级的hvigorfile.ts。

// 动态修改App包名加版本号，工程级hvigorfile.ts
import { appTasks , OhosPluginId} from '@ohos/hvigor-ohos-plugin';
import { hvigor } from '@ohos/hvigor'

hvigor.afterNodeEvaluate((hvigorNode)=>{
  const context = hvigorNode.getContext(OhosPluginId.OHOS_APP_PLUGIN)
  if (context && context.getBuildProfileOpt) {
    const buildProfile = context.getBuildProfileOpt();
    const products = buildProfile.app.products;
    for (const product of products) {
      if (product.name === context.getCurrentProduct().productBuildOpt.name) {
        product.output = {
          "artifactName": "Test"
        }
      }
    }
    context.setBuildProfileOpt(buildProfile);
  }
})

export default {
  system: appTasks, /* Built-in plugin of Hvigor. It cannot be modified. */
  plugins:[] /* Custom plugin to extend the functionality of Hvigor. */
}
