Question

我正在尝试测试一个简单的Python脚本来发出macOS通知：

import objc
import UserNotifications
from PyObjCTools import AppHelper

def notif_callback(err):
    print("Error in notification callback:",err)

def auth_callback(granted, err):
    print("Granted: ",granted,)
    print("Error in authorization request: ",err)

content=UserNotifications.UNMutableNotificationContent.alloc().init()
content.setTitle_("Test")
r=UserNotifications.UNNotificationRequest.requestWithIdentifier_content_trigger_('test_notification',content,None)


c=UserNotifications.UNUserNotificationCenter.currentNotificationCenter()

c.requestAuthorizationWithOptions_completionHandler_(0b111111,auth_callback)

c.addNotificationRequest_withCompletionHandler_(r,notif_callback)

input() # suspend the program

但是，当我尝试运行该程序时，它出现以下错误

Granted: False
Error in authorization request:  Error Domain=UNErrorDomain Code=1 "Notifications are not allowed for this application" UserInfo={NSLocalizedDescription=Notifications are not allowed for this application}
Error in notification callback: Error Domain=UNErrorDomain Code=1 "Notifications are not allowed for this application" UserInfo={NSLocalizedDescription=Notifications are not allowed for this application}

我没有从系统中看到任何通知授权，并且操作系统似乎自动拒绝了该请求。在系统偏好设置中，已向Python授予了所有通知权限。我在这里想念什么？

将仅授权经过代码签名的应用程序通过UNUserNotificationCenter发送用户通知。我认为这项要求是新的，不适用于NSUserNotificationCenter。

PyObjC“此应用程序不允许通知”
