键入objectId以解析云代码

Question

我试图将一些参数传递给我的Parse Cloud Code函数，并在Xcode中收到以下错误消息。 cannot convert value of type '[String : String?]' to type '[NSObject : AnyObject]' in coercion。它工作正常，直到我引用incomingUser.objectId。这是我传递的代码：

let params = ["userType" : userType, "recipient" : self.incomingUser.objectId]

PFCloud.callFunctionInBackground("pushNotification", withParameters: params as [NSObject : AnyObject]) {
    (res: AnyObject?, error: NSError?) -> Void in
      print(res)
      print(error)
}

感谢您提供的任何帮助。

请尝试使用params as [NSObject: AnyObject?]。

如果API需要[NSObject: AnyObject]，则必须先打开objectId。

guard let objectId = self.incomingUser.objectId else { return }

然后再做

let params = ["userType" : userType, "recipient" : objectId]

PFCloud.callFunctionInBackground("pushNotification", withParameters: params as [NSObject : AnyObject]) {
(res: AnyObject?, error: NSError?) -> Void in
    print(res)
    print(error)
}
