swift - iOS firebase 通知在后台不起作用

Question

您好，我调用了 Firebase 函数，如果应用程序已关闭或在后台，我会收到推送通知，但在此通知上还有其他数据，请参阅 JS 脚本。我的问题是我想在 Usersdefault 中写入这些数据但没有调用任何方法？！我不知道为什么。如果该应用程序在前台，则一切正常。在 Plist 我添加了 "FirebaseAppDelegateProxyEnabled" = NO JS 功能：

let title = "Test";
    let body =  "TestBody"; 
   
    const message = {
        notification: { title: title, body: body },
        apns: { 
            payload: { 
                aps: { 
                    "content_available" : 1,
                    sound: 'default', 
                    badge: 4,
                } 
            } 
        }, 
        token: "e0BURkoe0EAq....CIscNukai",
        data: { 
            event: "custom1", 
            type: "CustomTest",
        }
    }

Appdelegate.swift 查看块：

if ( userInfo["type"] as! String == "CustomTest" ) {
            ###########
            ###########
            DO SOMETHING

        }

您需要更改通知负载。您需要使用以下有效负载进行 IOS 通知。

aps：{警报：{标题：“标题”，正文：“正文”，名称：“名称”，事件：“custom1”，类型：“CustomTest”}}
