如何克服"Permission Denial....obtain access using ACTION_OPEN_DOCUMENT or related APIs"？

Question

我正在使用react-native-firebase和react-native-document-picker，我正在尝试遵循面部检测教程。

尽管通过权限Android具有读取访问权限，但当前仍收到以下错误：

Permission Denial: reading com.android.provides.media.MediaDocumentsProvider uri [uri] from pid=4746, uid=10135 requires that you obtain access using ACTION_OPEN_DOCUMENT or related APIs

我能够在屏幕上显示用户选定的图像，但 react-native-firebase 函数似乎无法获得许可。错误发生在此调用中：const faces = await vision().faceDetectorProcessImage(localPath);。

关于如何授予人脸检测功能访问权限的任何建议或我做错了什么？

我的 AndroidManifest.xml 文件包含以下内容：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

以下是该组件中的所有代码以供参考：

import React, {useState} from 'react';
import { Button, Text, Image, PermissionsAndroid } from 'react-native';
import vision, { VisionFaceContourType } from '@react-native-firebase/ml-vision';
import DocumentPicker from 'react-native-document-picker';

async function processFaces(localPath) {
console.log(localPath)
const faces = await vision().faceDetectorProcessImage(localPath);
console.log("Got faces")
faces.forEach(face => {
console.log('Head rotation on Y axis: ', face.headEulerAngleY);
console.log('Head rotation on Z axis: ', face.headEulerAngleZ);
console.log('Left eye open probability: ', face.leftEyeOpenProbability);
console.log('Right eye open probability: ', face.rightEyeOpenProbability);
console.log('Smiling probability: ', face.smilingProbability);
face.faceContours.forEach(contour => {
if (contour.type === VisionFaceContourType.FACE) {
console.log('Face outline points: ', contour.points);
}
});
});
}
async function pickFile () {
// Pick a single file
try {
const res = await DocumentPicker.pick({
type: [DocumentPicker.types.images],
});
console.log(
res.uri,
res.type, // mime type
res.name,
res.size
);
return res
} catch (err) {
if (DocumentPicker.isCancel(err)) {
// User cancelled the picker, exit any dialogs or menus and move on
console.log("User cancelled")
} else {
console.log("Error picking file or processing faces")
throw err;
}
}
}
const requestPermission = async () => {
try {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.READ_EXTERNAL_STORAGE,
{
title: "Files Permission",
message:
"App needs access to your files " +
"so you can run face detection.",
buttonNeutral: "Ask Me Later",
buttonNegative: "Cancel",
buttonPositive: "OK"
}
);
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
console.log("We can now read files");
} else {
console.log("File read permission denied");
}
return granted
} catch (err) {
console.warn(err);
}
};
function FaceDetectionScreen ({navigation}) {
const [image, setImage] = useState("");
return (
<>
<Text>This is the Face detection screen.</Text>
<Button title="Select Image to detect faces" onPress={async () => {
const permission = await requestPermission();
if (permission === PermissionsAndroid.RESULTS.GRANTED) {
const pickedImage = await pickFile();
const pickedImageUri = pickedImage.uri
setImage(pickedImageUri);
processFaces(pickedImageUri).then(() => console.log('Finished processing file.'));
}
}}/>
<Image style={{flex: 1}} source={{ uri: image}}/>
</>
); 
}
export default FaceDetectionScreen;

多亏了对 github 问题的评论，我能够更新我的代码并通过将 processFaces 的前三行更新为：

async function processFaces(contentUri) {
const stat = await RNFetchBlob.fs.stat(contentUri)
const faces = await vision().faceDetectorProcessImage(stat.path);

导入import RNFetchBlob from 'rn-fetch-blob'后.
