我有一个由mean-stack构建的网站。我使用File System在服务器中创建文件夹和写入文件。例如，在后端，我有：
localhost现在，我想在本地用户磁盘中创建文件夹。例如，当我在app.config(['$stateProvider', function ($stateProvider) {
$stateProvider
.state('fileSystem', {
url: '/fileSystem',
template: `hallo`,
controller: 'FileSystemCtrl'
})
}])
app.controller('FileSystemCtrl', ['$scope', '$http', function ($scope, $http) {
// var dir = "public/tmp/ABC" // creates well a folder under the folder of the project
var dir = "file:///USers/SoftTimur/theProject/public/tmp/DEF"
$http.post('/httpOnly/mkdir', { dir: dir })
.then(function () {
console.log("done")
})
}])
（Mac）中启动网站时，我希望它能够在我的Mac中创建一个文件夹。我试着在前端跟踪代码：
var dir = "file:///USers/SoftTimur/theProject/public/tmp/DEF"我希望，{ Error: ENOENT: no such file or directory, mkdir 'file:///USers/SoftTimur/theProject/public/tmp/DEF'
errno: -2,
code: 'ENOENT',
syscall: 'mkdir',
path: 'file:///USers/SoftTimur/theProject/public/tmp/DEF' }
可以在我的Mac上创建一个文件夹，但失败并显示错误：
close()有人怎么办？
答案 0 :(得分：0)
以下代码有效。发布json数据
{＆＃34; dir＆＃34;：＆＃34; / USers / softTimur / theProject / public / tmp / DEF＆＃34;}
我正在使用带有此库的密码提示的sudo命令 public static String makeScreen(View view) throws Exception {
String filename = "file.png";
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap b = view.getDrawingCache();
FileOutputStream file = null;
try {
file = new FileOutputStream(Environment.getExternalStorageDirectory().toString() + "folder/" + filename);
if (file != null) {
b.compress(Bitmap.CompressFormat.PNG, 98, file);
file.close();
}
view.destroyDrawingCache();
} catch (Exception e) { view.destroyDrawingCache(); }
}
