1.如果你的应用不是存储类型或者相机拍照类型你就需要用 kit.CameraKit Api 实现相机拍照和相册选择照片功能如果你不用这个的话你使用 picker.PhotoViewPicker 你就需要申请权限那你提交应用审核的时候就会被拒说你使用了敏感权限。
2.以下是自己封装的一个工具类可直接导入使用
import { camera, cameraPicker } from kit.CameraKit;
import { photoAccessHelper } from kit.MediaLibraryKit;
import fs from ohos.file.fs;
import { BusinessError } from kit.BasicServicesKit;
class PhotoPicker {
private imgSrc:string
//拍照
async takePhoto():Promisestring {
const pickerResult await cameraPicker.pick(getContext(),
[cameraPicker.PickerMediaType.PHOTO], {
cameraPosition: camera.CameraPosition.CAMERA_POSITION_BACK
});
this.saveImage(pickerResult.resultUri);
return this.imgSrc;
}
//从相册中选 photoAccessHelper版
async pickPhoto():Promisestring | void {
const PhotoSelectOptions new photoAccessHelper.PhotoSelectOptions();
PhotoSelectOptions.MIMEType photoAccessHelper.PhotoViewMIMETypes.IMAGE_TYPE;
//选择图片数量
PhotoSelectOptions.maxSelectNumber 1;
let photoPicker new photoAccessHelper.PhotoViewPicker();
try {
const res await photoPicker.select(PhotoSelectOptions)
if (res.photoUris.length 0) {
return
}
this.saveImage(res.photoUris[0])
return this.imgSrc;
} catch (e) {
console.log(img----err--,JSON.stringify(e))
}
}
//存到应用缓存
private saveImage(src:string){
try {
const destPath getContext(this).cacheDir
const fileType src.split(.)[1]
const fileName Date.now()
const path ${destPath}/${fileName}.${fileType}
const imgFile fs.openSync(src,fs.OpenMode.READ_ONLY)
const tempFile fs.openSync(path,fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE)
// 拷贝
fs.copyFileSync(imgFile.fd,tempFile.fd)
fs.close(imgFile)
fs.close(tempFile)
// 从沙箱中获取图片路径
// this.imgSrc fileUri.getUriFromPath(path)
this.imgSrc path
} catch (e) {
let err: BusinessError e as BusinessError;
console.info(img--[picker] Photo Save error JSON.stringify(err));
}
}
}
export const photoPicker new PhotoPicker()
