我正在尝试通过与我的 chrome 应用程序通信的“本机应用程序”程序调用程序“test.py”，它是我硬盘上的本地文件。但是，当我尝试通过 google chrome 运行应用程序时，chrome 应用程序不会运行“test.py”。但是，通过命令行执行我的本机应用程序会调用“test.py”并按预期工作。如何让我的“本机应用程序”程序通过 chrome 应用程序调用我硬盘上的本地 python 程序？

本机应用程序

如果您希望 chrome 应用程序访问系统上的本地文件，则必须指定程序的整个路径。

execfile("test.py")

应该有完整的路径

execfile("C:\\users\\abc\\test.py")
