]
}
]
}
],

{
"name": "ohos.abilitydemo.permission.PROVIDER",
"reason": "$string:reason",
"usedScene": {
"abilities": [
"FormAbility"
],
"when": "inuse"
}
}
]
}
}module.json5配置文件包含以下标签。
表1 module.json5配置文件配置标签说明
deviceTypes标签
表2 deviceType标签配置说明
deviceTypes示例：
{
"module": {
"name": "myHapName",
"type": "feature",

]
}
}pages标签
该标签是一个profile文件资源，用于指定描述页面信息的配置文件。
{
"module": {
// ...
"pages": "$profile:main_pages", // 通过profile下的资源文件配置
}
}在开发视图的resources/base/profile下面定义配置文件main_pages.json，其中文件名(main_pages)可自定义，需要和前文中pages标签指定的信息对应，配置文件中列举了当前应用组件中的页面信息。
表3 pages配置文件标签说明
{
"src": [
"pages/index/mainPage",
"pages/second/payment",
"pages/third/shopping_cart",
"pages/four/owner"
]
}metadata标签

},
{
"name": "extensionAbility_metadata_2",
"value": "a string test",
"resource": "$profile:config_file"
}],
}]
}
}abilities标签
abilities标签描述UIAbility组件的配置信息，标签值为数组类型，该标签下的配置只对当前UIAbility生效。
表6 abilities标签说明
abilities示例：
{
"abilities": [{
"name": "EntryAbility",
"srcEntry": "./ets/entryability/EntryAbility.ts",
"launchType":"singleton",
"description": "$string:description_main_ability",
"icon": "$media:icon",
"label": "Login",
"permissions": [],
"metadata": [],
"exported": true,
"continuable": true,
"skills": [{
"actions": ["ohos.want.action.home"],
"entities": ["entity.system.home"],
"uris": []
}],
"backgroundModes": [
"dataTransfer",
"audioPlayback",
"audioRecording",
"location",
"bluetoothInteraction",

"maxWindowWidth": 2560,
"minWindowWidth": 1400,
"maxWindowHeight": 300,
"minWindowHeight": 200,
"excludeFromMissions": false
}]
}skills标签
该标签标识UIAbility组件或者ExtensionAbility组件能够接收的Want的特征。
skills示例：
{
"abilities": [
{
"skills": [
{
"actions": [
"ohos.want.action.home"
],
"entities": [
"entity.system.home"
],
"uris": [
{
"scheme":"http",
"host":"example.com",
"port":"80",
"path":"path",
"type": "text/*"
}
]
}
]
}
]
}extensionAbilities标签
描述extensionAbilities的配置信息，标签值为数组类型，该标签下的配置只对当前extensionAbilities生效。
表9 extensionAbilities标签说明
extensionAbilities示例：
{
"extensionAbilities": [
{
"name": "FormName",
"srcEntry": "./form/MyForm.ts",
"icon": "$media:icon",
"label" : "$string:extension_name",
"description": "$string:form_description",
"type": "form",
"permissions": ["ohos.abilitydemo.permission.PROVIDER"],
"readPermission": "",
"writePermission": "",
"exported": true,
"uri":"scheme://authority/path/query",
"skills": [{
"actions": [],
"entities": [],
"uris": []
}],
"metadata": [
{
"name": "ohos.extension.form",
"resource": "$profile:form_config",
}
]
}
]
}requestPermissions标签
该标签标识应用运行时需向系统申请的权限集合。
说明
在requestPermissions标签中配置的权限项将在应用级别生效，即该权限适用于整个应用程序。
如果应用需要订阅自己发布的事件，而且应用在extensionAbilities标签中的permissions字段中设置了访问该应用所需要的权限，那么应用也需要在requestPermissions标签中注册相关权限才能收到该事件。
requestPermissions示例：
{
"module" : {
"requestPermissions": [
{
"name": "ohos.abilitydemo.permission.PROVIDER",
"reason": "$string:reason",
"usedScene": {
"abilities": [
"EntryFormAbility"
],
"when": "inuse"
}
}
]
}
}shortcuts标签
shortcuts标识应用的快捷方式信息。标签值为数组，最多可以配置四个快捷方式。其包含四个子标签shortcutId、label、icon、wants。
metadata中指定shortcut信息，其中：
name：指定shortcuts的名称。使用ohos.ability.shortcuts作为shortcuts信息的标识。
resource：指定shortcuts信息的资源位置。
表11 shortcuts标签说明
在/resource/base/profile/目录下配置shortcuts_config.json配置文件。
{
"shortcuts": [
{
"shortcutId": "id_test1",
"label": "$string:shortcut",
"icon": "$media:aa_icon",
"wants": [
{
"bundleName": "com.ohos.hello",
"abilityName": "EntryAbility"
}
]
}
]
}在module.json5配置文件的abilities标签中，针对需要添加快捷方式的UIAbility进行配置metadata标签，使shortcut配置文件对该UIAbility生效。
{
"module": {
// ...
"abilities": [
{
"name": "EntryAbility",
"srcEntry": "./ets/entryability/EntryAbility.ts",
// ...
"skills": [
{
"entities": [
"entity.system.home"
],
"actions": [
"ohos.want.action.home"
]
}
],
"metadata": [
{
"name": "ohos.ability.shortcuts",
"resource": "$profile:shortcuts_config"
}
]
}
]
}
}distributionFilter标签
该标签下的子标签均为可选字段，用于定义HAP对应的细分设备规格的分发策略，以便应用市场在云端分发HAP时做精准匹配。该标签需要配置在/resource/profile资源目录下;在进行分发时，通过deviceType与下表属性的匹配关系，唯一确定一个用于分发到设备的HAP。
表12 distributionFilter标签说明
在开发视图的resources/base/profile下面定义配置文件distro_filter_config.json，文件名可以自定义。
{
"distributionFilter": {
"screenShape": {
"policy": "include",
"value": [
"circle",
"rect"
]
},
"screenWindow": {
"policy": "include",
"value": [
"454*454",
"466*466"
]
},
"screenDensity": {
"policy": "exclude",
"value": [
"ldpi",
"xldpi"
]
},
"countryCode": { // 支持中国和香港地区分发
"policy": "include",
"value": [
"CN",
"HK"
]
}
}
}在module.json5配置文件的module标签中定义metadata信息。
{
"module": {
// ...
"metadata": [
{
"name": "ohos.module.distro",
"resource": "$profile:distro_filter_config",
}
]
}
}testRunner标签
此标签用于支持对测试框架的配置。
表17 testRunner标签说明
testRunner标签示例：
{
"module": {
// ...
"testRunner": {
"name": "myTestRunnerName",
"srcPath": "etc/test/TestRunner.ts"
}
}
}
