Chrome扩展程序保存临时文件
[英]Chrome Extension save temporary file
问题描述
I have a Chrome Extension that needs to temporarily save a few (two or three) PNG images. 
我有一个Chrome扩展程序，该扩展程序需要暂时保存一些（两个或三个）PNG图片。
What I am currently doing is getting the image data URI, and saving this in localstorage. 我目前正在做的是获取图像数据URI，并将其保存在localstorage中。 But I know that this is not a very good way of doing it, especially as some of the images are bigger than 5mb, and I therefore have difficulty storing them. 但是我知道这不是一个很好的方法，特别是当某些图像大于5mb时，因此很难存储它们。
I've seen a few extensions (Single File Extension, and a few others) that have the ability of "saving" a temporary file in the extension folder, but I am not sure how I can achieve this. 我已经看到了一些扩展名（单个文件扩展名和其他一些扩展名），它们能够将临时文件“保存”在扩展名文件夹中，但是我不确定如何实现。
Can anyone help me out? 谁能帮我吗？

You can use HTML5 FileSystem APIs to save your images to a target directory. 您可以使用HTML5 FileSystem API将图像保存到目标目录。
If your option is not limited to chrome extensions, you can write an chrome app, and then chrome.fileSystem is available to you. 如果您的选择不限于chrome扩展名，则可以编写一个chrome应用程序，然后chrome.fileSystem可用。
