鸿蒙开发(二)-项目结构

上篇文章我们讲了如何配置鸿蒙开发的基础环境，以及创建了第一个鸿蒙程序。

这篇我们讲述了鸿蒙应用的项目目录结构。

如图所示：我们切换项目project可以看到。

另一种则是Ohos模式:

AppScope->app.json5 应用的全局配置

{
  "app": {
    "bundleName": "com.zh.test",
    "vendor": "example",
    "versionCode": 1000000,
    "versionName": "1.0.0",
    "icon": "$media:app_icon",
    "label": "$string:app_name"
  }
}

包含包名，icon,label等信息。

vendor 为应用程序的供应商，默认如上为example

entry: 应用/服务模块，编译构建生成一个HAP.

entry->src->main->ets: 存放ArkTsUI源码，包含entryability以及pages

entry->src->main->resources:资源文件，如icon,字符串，布局文件等。

entry->src->main->module.json5：模块配置文件，包含abilities以及pages的配置

entry->src->build-profile.json5 ：模块信息，taget等

entry->src->hvigorfile.ts ：

entry->src->oh-package.json5 ：配置三方依赖
```
{
  "name": "entry",
  "version": "1.0.0",
  "description": "Please describe the basic information.",
  "main": "",
  "author": "",
  "license": "",
  "dependencies": {}
}
```

build.profile.json5:应用级配置，如签名，产品配置等信息

默认配置如下：

{
  "app": {
    "signingConfigs": [],
    "compileSdkVersion": 9,
    "compatibleSdkVersion": 9,
    "products": [
      {
        "name": "default",
        "signingConfig": "default",
      }
    ]
  },
  "modules": [
    {
      "name": "entry",
      "srcPath": "./entry",
      "targets": [
        {
          "name": "default",
          "applyToProducts": [
            "default"
          ]
        }
      ]
    }
  ]
}

hvigorfile.ts：应用级编译构建任务脚本.

默认配置如下：

// Script for compiling build behavior. It is built in the build plug-in and cannot be modified currently.
export { appTasks } from '@ohos/hvigor-ohos-plugin';

local.properties :

# This file is automatically generated by DevEco Studio.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file should *NOT* be checked into Version Control Systems,
# as it contains information specific to your local configuration.
#
# For customization when using a Version Control System, please read the header note.
hwsdk.dir=E:/harmony_os_sdk
nodejs.dir=C:/Users/zj/nodejs

这里配置了OpenHarmony SDK的路径，以及node.js的路径。
