如何从ios相机胶卷的准确URI路径中获取拾取的图像？

import Photos

func getImageDataFromURI(uri: String) -> Data? {
    if let url = URL(string: uri), let asset = PHAsset.fetchAssets(withALAssetURLs: [url], options: nil).firstObject {
        let options = PHImageRequestOptions()
        options.isSynchronous = true
        
        var imageData: Data?
        PHImageManager.default().requestImageData(for: asset, options: options) { (data, _, _, _) in
            imageData = data
        }
        
        return imageData
    }
    
    return nil
}
