当我尝试使用ionic-native文件列出我的文件夹目录时,我没有得到任何结果文件夹。
我的代码:
this.platform.ready().then(() => {
this.filesystem.listDir(this.filesystem.applicationStorageDirectory, '').then((result) => {
console.log(result);
/*result will have an array of file objects with
file details or if its a directory*/
for (let file of result) {
if (file.isDirectory == true && file.name != '.' && file.name != '..') {
console.log("This is a folder");
// Code if its a folder
} else if (file.isFile == true) {
// Code if its a file
console.log("This is a file");
let name = file.name // File name
console.log("file name: " + name);
// let path = file.path // File path
file.getMetadata(function (metadata) {
let size = metadata.size; // Get file size
})
}
}
});
});
我正在使用:“@ ionic-native / file”:“4.12.0”,使用import:import {File}来自'@ ionic-native / file';
您尚未在this.filesystem.listDir(this.filesystem.applicationStorageDirectory, '')
中传递目录名称,您必须在此方法中传递目录名称。您可以从this.filesystem.applicationStorageDirectory
获取目录名称。首先提醒this.filesystem.applicationStorageDirectory
并检查您获得的路径类型。
如果路径是这样的:
文件:///存储/仿真器/ 0 / somefolder
然后获取目录名称如下:
let appStorageDir = "file:///storage/emulator/0/somefolder";
let dirName = appStorageDir.substring(appStorageDir.lastIndexOf("/")+1);
如果在最后一个路径中有斜杠(/),例如:
文件:///存储/仿真器/ 0 / somefolder /
然后获取目录名称如下:
let appStorageDir = "file:///storage/emulator/0/somefolder/";
appStorageDir = appStorageDir.substring(0,appStorageDir.lastIndexOf("/"));
let dirName = appStorageDir.substring(appStorageDir.lastIndexOf("/")+1);
现在在方法中传递dirName如下:
this.filesystem.listDir(this.filesystem.applicationStorageDirectory, dirName)
希望它能帮到你!!!
