uniapp能获取手机可用存储空间吗

同问，大佬有解决方法了吗

暂无官方api,建议使用插件实现

/**

• @deprecated 获取手机剩余空间
• @returns {string}
  */

export default function() {
var internalMemSize = {};
if (plus.os.name == "Android") {
var environment = plus.android.importClass("android.os.Environment");
var statFs = plus.android.importClass("android.os.StatFs");
var files = plus.android.importClass("java.io.File");
var Files = environment.getDataDirectory();
var StatFs = new statFs(Files.getPath());
var blockSize = parseFloat(StatFs.getBlockSize());
var blockCount = parseFloat(StatFs.getBlockCount());
internalMemSize = blockSize * blockCount;
} else if (plus.os.name == "iOS") {
var BundleClass = plus.ios.importClass("NSBundle");
var BundleObj = BundleClass.mainBundle();
var filenamagerobj = plus.ios.newObject("NSFileManager");
var FileAttr = plus.ios.invoke(filenamagerobj, "attributesOfFileSystemForPath:error:", BundleObj.bundlePath(),null);
var surplus = plus.ios.invoke(FileAttr, "objectForKey:", "NSFileSystemFreeSize");
var NSFileSystemFreeSize = plus.ios.newObject("NSNumberFormatter");
internalMemSize = plus.ios.invoke(NSFileSystemFreeSize, "stringFromNumber:", surplus);
}
return internalMemSize
}
