如何通过本地消息铬应用程序调用本地python程序

Question

我正试图通过与chrome应用程序通信的"本机应用程序"程序调用程序"test.py"，这是我硬盘上的一个本地文件。然而，当我尝试通过谷歌chrome运行chrome应用程序时，该应用程序不会运行"test.py"。然而，通过命令行执行本机应用程序会调用"test.py"并按预期工作。如何通过chrome应用程序使我的"本机应用程序"程序调用硬盘上的本地python程序？

如果你想让chrome应用程序访问系统上的本地文件，你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")
