如何阅读React Native的文件内容？ // react-native-f不起作用

我目前正在处理一个反应本应用程序，该应用程序要求用户从其手机中选择文本文件并阅读它，我已经实施了该部分，要求用户使用expo-cocument-picker < /代码>，但我无法读取文件内容。

我已经尝试使用react-native-fs而没有任何成功：

            const content = async (file_path) => {
                let response = undefined;
                try {
                    response = await RNFS.readFile(path);
                } catch (err) {
                    showAlert("Failed to read file")
                    throw err;
    
                }
                return response;
            }

我得到的只是以下错误：

null不是对象（评估rnfsmanager.rnfsfiletypereperegular）

此时已经阅读了与该问题有关的所有问题和堆叠式帖子，但是建议的解决方案（例如npm install-save react-native-fs 或重置高速缓存都行不通。

也许是因为我使用博览会？如何读取文件whitout react-native-fs？

编辑：我已经尝试使用 filesystem 与函数readAssTringAsync，但它始终返回以下内容：{“ _ u”：0，“ _v”：0，” _w“：null，” _x“：null}”

我感谢帮助！

原文

I am currently working on a react-native application that is asking the user to pick a text file from its phone and read it, I already implemented the part that ask the user to choose a file using expo-document-picker but I cannot manage to read the file content.

I already try using react-native-fs without any success :

            const content = async (file_path) => {
                let response = undefined;
                try {
                    response = await RNFS.readFile(path);
                } catch (err) {
                    showAlert("Failed to read file")
                    throw err;
    
                }
                return response;
            }

All I get is the following error :

null is not an object (evaluating RNFSManager.RNFSFileTypeRegular)

At this point I have read every issues and stackOverflow post related to the problem but the suggested solutions like npm install --save react-native-fsor reseting the cache does not work.

Perhaps it is because I use expo ? How can I read a file whitout react-native-fs ?

edit : I already tried to use FileSystem with the function readAsStringAsync but it always return the following : {"_U":0, "_V":0, "_W": null, "_X": null}"

I appreciate the help !
