将下载的文件保存在www Folder ionic 2中 [英] Save Downloaded File in www Folder ionic 2

问题描述

我正在创建一个应用程序，用户需要使用大型数据库。而不是让用户下载数据并在客户端上填充SQLite数据库（这需要很长时间），我希望我可以使用可下载的预先填充的数据库。

I'm creating an app where users need to work with large databases. Rather than having the users download the data and populate an SQLite database on the client (which would take a long time), I'm hoping I can use downloadable, pre-populated databases.

我找到了 cordova-sqlite-ext ，它允许使用pre-填充的数据库，但SQLite文件必须位于 www 文件夹中才能生效。实际上是否可以将文件下载到Ionic / Cordova中的文件夹（在非root设备上）？

I found cordova-sqlite-ext, which allows working with pre-populated databases, but SQLite files must be located in the www folder for this to work. Is it actually possible to download files to this folder in Ionic/Cordova (on non-rooted devices)?

推荐答案

总是好的练习将文件存储在应用程序的目录中。检查我的评论，看看它是否对你有帮助：

It's always good practise to store your files in app's directory. Check this comment of mine and see if it helps you:

我需要下载一个zip文件（包含sqlite文件），解压缩文件，将文件存储在应用程序的目录中并查询数据库。我能够使用插件实现它并且工作得很好。

I had a requirement of downloading a zip file(with sqlite file in it), unzip the file, store the file in app's directory and query the DB. I was able to achieve it using plugins and works quite well.
