操作相机(拍照和录像)
// 唤起相机
async openCamera() {
const profile: cameraPicker.PickerProfile = {
cameraPosition: camera.CameraPosition.CAMERA_POSITION_BACK
}
const result: cameraPicker.PickerResult = await cameraPicker.pick(getContext(),
[cameraPicker.PickerMediaType.PHOTO, cameraPicker.PickerMediaType.VIDEO],
profile)
// promptAction.showDialog({
// message: JSON.stringify(result)
// })
// result.resultUri
if (result.mediaType === 'photo' && result.resultUri !== '') {
// 拍照
const newFile = getContext().filesDir + '/' + Date.now() + '.jpg'
const file = fileIo.openSync(result.resultUri, fileIo.OpenMode.READ_ONLY)
fileIo.copyFileSync(file.fd, newFile)
const newMessage = new MessageInfoModel({
sendUser: currentUser,
connectUser: this.talker,
messageContent: '[图片]',
messageType: MessageTypeEnum.IMAGE,
sourceFilePath: newFile
} as MessageInfo)
// 借用发图的方法
this.sendImageMsg([newMessage])
} else if (result.mediaType === 'video' && result.resultUri !== '') {
// 拍视频
const newFile = getContext().filesDir + '/' + Date.now() + '.mp4'
const file = fileIo.openSync(result.resultUri, fileIo.OpenMode.READ_ONLY)
fileIo.copyFileSync(file.fd, newFile)
const newMessage = new MessageInfoModel({
sendUser: currentUser,
connectUser: this.talker,
messageContent: '[视频]',
messageType: MessageTypeEnum.VIDEO,
sourceFilePath: newFile,
} as MessageInfo)
this.sendImageMsg([newMessage])
}
}
拍照和从相机选则照片
//拍照
async takePhoto() {
let myContext = getContext() as common.Context
const result = await cameraPicker.pick(myContext,
[cameraPicker.PickerMediaType.PHOTO],
{
cameraPosition: camera.CameraPosition.CAMERA_POSITION_BACK
}
)
Log.info('takePhoto:' + result.resultUri)
// 都是拿到了图
// result.resultUri
if (result.resultUri) {
this.callback(result.resultUri)
}
}
//从相册选则
async pickPhoto() {
// 变动：从picker 刚更新为 photoAccessHelper
const photo = new photoAccessHelper.PhotoViewPicker()
const result = await photo.select({
MIMEType: photoAccessHelper.PhotoViewMIMETypes.IMAGE_TYPE,
maxSelectNumber: 1
})
// 都是拿到了图
// result
Log.info('picker' + result.photoUris[0])
if (result.photoUris?.length) {
this.callback(result.photoUris[0])
}
}

若需避免直接申请相机或相册权限，可使用系统选择器（Picker）
1/图片选择场景：通过 PhotoViewPicker 调用系统相册界面，用户选择图片时自动获取临时权限，无需主动申请 ohos.permission.READ_IMAGEVIDEO。
示例：
let photoPicker = new picker.PhotoViewPicker();
photoPicker.select().then((photoSelectResult) => {
// 处理用户选择的图片
});
2/拍照或录像场景：使用 CameraPicker 直接调用系统相机界面，用户操作时临时授权，无需应用主动申请 ohos.permission.CAMERA。适用基础拍摄需求，如上传头像、拍摄简单内容。
CameraPicker（系统相机选择器）功能：拉起系统相机界面进行拍照或录像，PhotoViewPicker（相册选择器）功能：拉起系统相册界面
