Question

我想从firebase推送通知中解析数据，并且数据与“ aps”一起出现，我在解析时遇到了困难。这是我在推送中接收的数据。我想解析“ PnType”，“提取”。

[
  AnyHashable("CustomData"): 
  {
    "PnType":"PnNewJob",
    "PnResult":
    {
      "JobId":1743,
      "JobRef":"CAS4491055071",
      "Pickup":"Basil And Bean Co, phase-7, Mohali, Punjab, India",
      "DropOff":"Elante Mall, Chandigarh, Chandigarh, India",
      "Cost":9.00,
      "TotalMiles":4.93
    }
  },
  AnyHashable("google.c.a.e"): 1,
  AnyHashable("gcm.message_id"): 0:1555505650971833%277c5a32277c5a32,
  AnyHashable("aps"):
  {
    alert =  
    {
        body = "Hellodrive Notification";
        title = "HelloDrive Notification";
    };
    badge = 1;
    "content-available" = 1; 
  }
]

我尝试像

那样解析

let customData = userInfo["CustomData"] as? [AnyHashable: Any]

我每次都变得零。

我尝试使用NWPusher应用推送通知。

推送了JSON：

{
  "CustomData": {
    "PnType": "PnNewJob",
    "PnResult": {
      "JobId": 1743,
      "JobRef": "CAS4491055071",
      "Pickup": "Basil And Bean Co, phase-7, Mohali, Punjab, India",
      "DropOff": "Elante Mall, Chandigarh, Chandigarh, India",
      "Cost": 9,
      "TotalMiles": 4.93
    }
  },
  "google.c.a.e": 1,
  "gcm.message_id": "0:1555505650971833%277c5a32277c5a32",
  "aps": {
    "alert": {
      "body": "Hellodrive Notification",
      "title": "HelloDrive Notification"
    },
    "badge": 1,
    "content-available": 1
  }
}

以下是didReceiveRemoteNotification

中收到的内容

[[AnyHashable("aps"): {
    alert =     {
        body = "Hellodrive Notification";
        title = "HelloDrive Notification";
    };
    badge = 1;
    "content-available" = 1;
}, AnyHashable("google.c.a.e"): 1, AnyHashable("CustomData"): {
    PnResult =     {
        Cost = 9;
        DropOff = "Elante Mall, Chandigarh, Chandigarh, India";
        JobId = 1743;
        JobRef = CAS4491055071;
        Pickup = "Basil And Bean Co, phase-7, Mohali, Punjab, India";
        TotalMiles = "4.93";
    };
    PnType = PnNewJob;
}, AnyHashable("gcm.message_id"): 0:1555505650971833%277c5a32277c5a32]]

现在，我使用userInfo方法中的以下代码从didReceiveRemoteNotification中检索了值。它工作得很好。

    if let customData = userInfo["CustomData"] as? [AnyHashable: Any] {

        if let pnType = customData["PnType"] as? String {
            print("PNType: \(pnType)")
        }

        if let pnResult = customData["PnResult"] as? [AnyHashable: Any] {
            if let pickup = pnResult["Pickup"] as? String {
                print("Pickup: \(pickup)")
            }
        }
    }

输出

PNType: PnNewJob
Pickup: Basil And Bean Co, phase-7, Mohali, Punjab, India

首先将userInfo转换为更具体的[String:Any]，然后提取值

if let userInfo = userInfo as? [String:Any],
   let customData = userInfo["CustomData"] as? [String:Any] {
     let pnType = customData["PnType"] as? String
     print(pnType ?? "n/a")
     if let pnResult = customData["PnResult"] as? [String:Any],
        let pickup = pnResult["Pickup"] as? String {
          print(pickup)
     }

}

我无法解析推送通知中的数据
