cl.theme.1 API9接口支持异常处理

下列模块内部接口使用业务逻辑返回值表示错误信息，不符合OpenHarmony接口错误码规范。在API9进行变更。 - 壁纸管理服务：@ohos.wallpaper.d.ts

锁屏管理服务：@ohos.screenLock.d.ts

以上模块中的接口变更为：同步接口：通过抛出异常的方式返回错误信息。异步接口：参数检查错误同步抛出，业务逻辑错误通过AsyncCallback或Promise的error对象抛出。

变更影响

基于此前版本开发的应用，需适配接口的错误信息返回方式，否则会影响原有业务逻辑。

关键接口/组件变更

以下标记为壁纸管理服务接口废除： - getColors(wallpaperType: WallpaperType, callback: AsyncCallback>): void; - getColors(wallpaperType: WallpaperType): Promise>; - getId(wallpaperType: WallpaperType, callback: AsyncCallback): void; - getId(wallpaperType: WallpaperType): Promise; - getMinHeight(callback: AsyncCallback): void; - getMinHeight(): Promise; - getMinWidth(callback: AsyncCallback): void; - getMinWidth(): Promise; - isChangePermitted(callback: AsyncCallback): void; - isChangePermitted(): Promise; - isOperationAllowed(callback: AsyncCallback): void; - isOperationAllowed(): Promise; - reset(wallpaperType: WallpaperType, callback: AsyncCallback): void; - reset(wallpaperType: WallpaperType): Promise; - setWallpaper(source: string|image.PixelMap, wallpaperType: WallpaperType, callback: AsyncCallback): void; - setWallpaper(source: string|image.PixelMap, wallpaperType: WallpaperType): Promise; - getFile(wallpaperType: WallpaperType, callback: AsyncCallback): void; - getFile(wallpaperType: WallpaperType): Promise; - getPixelMap(wallpaperType: WallpaperType, callback: AsyncCallback): void; - getPixelMap(wallpaperType: WallpaperType): Promise;

壁纸管理服务替代接口如下: - getColorsSync(wallpaperType: WallpaperType): Array; - getIdSync(wallpaperType: WallpaperType): number; - getMinHeightSync(): number; - getMinWidthSync(): number; - isChangeAllowed(): boolean; - isUserChangeAllowed(): boolean; - restore(wallpaperType: WallpaperType, callback: AsyncCallback): void; - restore(wallpaperType: WallpaperType): Promise; - setImage(source: string|image.PixelMap, wallpaperType: WallpaperType, callback: AsyncCallback): void; - setImage(source: string|image.PixelMap, wallpaperType: WallpaperType): Promise; - getFileSync(wallpaperType: WallpaperType): number; - getImage(wallpaperType: WallpaperType, callback: AsyncCallback): void; - getImage(wallpaperType: WallpaperType): Promise;

以下标记为壁纸管理服务接口变更： - on(type: ‘colorChange’, callback: (colors: Array, wallpaperType: WallpaperType) => void): void - off(type: ‘colorChange’, callback?: (colors: Array, wallpaperType: WallpaperType) => void): void

以下标记为锁屏管理服务接口废除： - isScreenLocked(callback: AsyncCallback): void; - isScreenLocked(): Promise; - isSecureMode(callback: AsyncCallback): void; - isSecureMode(): Promise; - unlockScreen(callback: AsyncCallback): void; - unlockScreen(): Promise;

锁屏管理服务替代接口如下: - isLocked(): boolean; - isSecure(): boolean; - unlock(callback: AsyncCallback): void; - unlock():Promise;

以下标记为锁屏管理服务接口删除： - lockScreen(callback: AsyncCallback): void; - lockScreen(): Promise;

以下标记为锁屏管理服务接口新增： - lock(callback: AsyncCallback): void; - lock():Promise;

以下标记为锁屏管理服务接口变更： - onSystemEvent(callback: Callback): boolean; - sendScreenLockEvent(event: String, parameter: number, callback: AsyncCallback): void; - sendScreenLockEvent(event: String, parameter: number): Promise;

壁纸管理服务适配指导

异步接口以getImage为例，示例代码如下：

import pointer from '@ohos.wallpaper';
try {
    wallpaper.getImage(wallpaper.WallpaperType.WALLPAPER_SYSTEM).then((data) => {
        console.log(`success to getImage: ${JSON.stringify(data)}`);
    }).catch((error) => {
        console.error(`failed to getImage because: ${JSON.stringify(error)}`);
    });
} catch (err) {
    console.error(`failed to getImage because: ${JSON.stringify(err)}`);
}

同步接口以getFileSync为例，示例代码如下：

import pointer from '@ohos.wallpaper';
try {
    let file = wallpaper.getFileSync(wallpaper.WallpaperType.WALLPAPER_SYSTEM);
} catch (err) {
    console.error(`failed to getFileSync because: ${err.message}`);
}

锁屏管理服务适配指导

异步接口以lock为例，示例代码如下：

import screenLock from '@ohos.screenlock';
try {
  screenLock.lock((err, data) => {      
    if (err) {
        console.error(`Failed to lock the screen, because: ${err.message}`);
        return;    
    }
    console.info(`lock the screen successfully. result: ${data}`);
  });
} catch (err) {
    console.error(`Failed to lock the screen, because: ${err.message}`);
}

同步接口以onSystemEvent为例，示例代码如下：

import screenLock from '@ohos.screenlock';
try {
   let isSuccess = screenLock.onSystemEvent((event) => {
       console.log(`Register the system event which related to screenlock successfully. eventType: ${event.eventType}`)
   });
} catch (err) {
   console.error(`Failed to register the system event which related to screenlock, because: ${err.message}`)
}
