How to get Data Uri from a file system image with javascript (localhost is not an option)

Question

我正在写一个可在mozilla上离线运行的javascript应用程序。我需要从文件系统中获取一个图像并将其读取为datauri（没有拖放或输入，必须由url自动完成）.Localhost不是一个选择。另一种方法是从封闭网络的URL中获取此图像，但应用程序无法在该网络上，因此我无法使用来自文件系统的Ajax调用。任何解决方案？

Browsers javascript implementation doesn't have access to local file system due security considerations. You will have to run some sort of web server to serve that file.
