python - 操作系统: programmatically get list of applications for a file

Question

在查找器中，用户可以右键单击/“打开方式”并查看可用于打开文件的应用程序列表。

如何以编程方式获取此应用程序列表？

首选 ObjC 或 Python，但也好奇是否有公开此功能的命令行实用程序。

Answer 1

NSArray *applicationURLs = CFBridgingRelease(LSCopyApplicationURLsForURL((__bridge CFURLRef)fileURL, kLSRolesAll));
NSLog(@"applicationURLs %@", applicationURLs);

//输出

applicationURLs (
    "file:///Applications/calibre.app/",
    "file:///Applications/Archiver.app/",
    "file:///Applications/Pacifist.app/",
    "file:///System/Library/CoreServices/Archive%20Utility.app/"
)

对于默认应用程序:

   CFURLRef defaultApplicationForURL = NULL;
   LSGetApplicationForURL((__bridge CFURLRef)fileURL, kLSRolesAll, NULL, &defaultApplicationForURL);
   NSLog(@"deafultApplicationForURL %@", defaultApplicationForURL);

//输出

deafultApplicationForURL file:///System/Library/CoreServices/Archive%20Utility.app/
