在一个本机反应项目中，我在android_assets文件夹中有一个压缩文件。我想解压缩该文件夹并将其复制到DocumentDirectoryPath中。我已经导入了react-native-zip-archive并使用了unzipAssets，但是它似乎不起作用。我使用了以下代码，但出现错误：无法打开“ ./ICF-Package”。
const assetPath ='./ICF-Package.zip'
const targetPath = ${DocumentDirectoryPath}/ICF-Package.zip
copyfile() {
unzipAssets(assetPath,targetPath)
.then(() => {
console.log('unzip completed!')
})
.catch((error) => {
console.log(error)
})
}
您可以安装它并尝试解决问题。
$ npm install react-native-fetch-blob $ react-native link react-native-fetch-blob import RNFetchBlob from 'react-native-fetch-blob';
import { unzip } from 'react-native-zip-archive';
let dirs = RNFetchBlob.fs.dirs
const documentPath = dirs.DocumentDir
const resourceUrl = 'file:///android_asset/target.zip'
downloadResource = () => {
// Set the path to store on the device
const dirs = RNFetchBlob.fs.dirs.DocumentDir
const homePath = dirs + '/target.zip'
RNFetchBlob
.config({
path: homePath
})
.fetch('GET',resourceUrl)
.progress((received,total) => {
const percentage = Math.floor(received / total * 10000) / 100 + '%'
console.log(percentage)
})
.then(resourceFile => {
console.log('target.zip file download success')
this.unzip(resourceFile);
})
.catch((errorMessage,statusCode) => {
console.log(errorMessage);
})
}
unzip = resourceFile => {
const resourcePath = resourceFile.path()
unzip(resourcePath,documentPath)
.then(path => {
console.log(`unzip sucess: ${path}`)
})
}
