如何获取Finder选择的文件的posix路径？

tell application "Finder"
    set selectedItems to selection
    if (count of selectedItems) is 1 then
        set selectedItem to item 1 of selectedItems
        set itemPath to POSIX path of (selectedItem as alias)
        return itemPath
    else
        return "请选择一个文件"
    end if
end tell

NSAppleScript *script = [[NSAppleScript alloc] initWithContentsOfURL:[NSURL fileURLWithPath:@"/path/to/get_selected_file_path.scpt"] error:nil];
NSDictionary *errorInfo = nil;
NSAppleEventDescriptor *result = [script executeAndReturnError:&errorInfo];
if (!errorInfo) {
    NSString *posixPath = [result stringValue];
    NSLog(@"%@", posixPath);
} else {
    NSLog(@"执行脚本出错：%@", errorInfo);
}

import Foundation

let scriptURL = URL(fileURLWithPath: "/path/to/get_selected_file_path.scpt")
var error: NSDictionary?
if let script = NSAppleScript(contentsOf: scriptURL, error: &error) {
    if let output = script.executeAndReturnError(&error).stringValue {
        print(output)
    } else if let error = error {
        print("执行脚本出错：\(error)")
    }
} else if let error = error {
    print("加载脚本出错：\(error)")
}

import subprocess

script_path = "/path/to/get_selected_file_path.scpt"
result = subprocess.run(["osascript", script_path], capture_output=True, text=True)
if result.returncode == 0:
    posix_path = result.stdout.strip()
    print(posix_path)
else:
    print(f"执行脚本出错：{result.stderr}")
