解析推送通知云代码错误？

Question

更新：我收到此错误是因为 Parse-Server 2.2.17 有一个错误。我通过回到 2.2.16 来修复它。

有人知道我为什么会收到这个错误吗？这是我的云代码：

`Parse.Cloud.define("Messages", function(request, response) {

var pushQuery = new Parse.Query(Parse.Installation);

Parse.Push.send({
    where: pushQuery,
    data: {
    alert: "New Event Added",
    sound: "default"
    }
    },{
    success: function(){
        console.log("Push Sent!")
    },
    error: function (error) {
        console.log(error)
    },
  useMasterKey: true

}); });`

这是我得到的错误：

这就是我调用代码的方式：`PFCloud.callFunctionInBackground("Messages", withParameters: nil) { (object, error) in

            if error == nil {

                print("Success!")

            } else {

                print(error)
            }
        }

index.js: `

你能不能试试下面的代码：

var query = new Parse.Query(Parse.Installation);
// query condition (where equal to .. etc.)

var payload = {
    alert: "New Event Added",
    sound: "default" 
};





Parse.Push.send({
    where: query, // Set our Installation query
    data: payload
}, {
        success: function () {

        },
        error: function (error) {
            // Handle error
        }
    });

请注意我删除了 useMasterKey，如果你想添加 useMasterKey，你需要将它插入到闭包中，但对我来说，它可以在没有 useMasterKey 的情况下工作

useMasterKeyVersion 应如下所示：

Parse.Push.send({
    where: query, // Set our Installation query
    data: payload
},
{
   useMasterKey: true
},
{
    success: function () {

    },
    error: function (error) {
        // Handle error
    }
});

promise 版本（根据最佳实践）：

Parse.Push.send({where: query,data: payload})
.then(function(){
    // success
},function(error){
    // error .. 
});

更新

通过查看您的 index.js 文件，您似乎没有将 facebook oauth 添加到您的 3 方身份验证登录中。 所以你需要添加以下内容：

oauth: {
   facebook: {
     appIds: "FACEBOOK APP ID"
   }
}

在您的 emailAdapter 配置下方和“FACEBOOK APP ID”内放置您在 facebook 开发人员中创建的应用 ID

在 main.js 中放入这段代码

// SEND PUSH NOTIFICATION
Parse.Cloud.define("push", function(request, response) {

  var user = request.user;
  var params = request.params;
  var someKey = params.someKey
  var data = params.data

  var recipientUser = new Parse.User();
  recipientUser.id = someKey;

  var pushQuery = new Parse.Query(Parse.Installation);
  pushQuery.equalTo("userID", someKey);


  Parse.Push.send({
    where: pushQuery, // Set our Installation query
    data: data
  }, { success: function() {
      console.log("#### PUSH OK");
  }, error: function(error) {
      console.log("#### PUSH ERROR" + error.message);
  }, useMasterKey: true});

  response.success('success');
});



// SEND PUSH NOTIFICATION FOR ANDROID
Parse.Cloud.define("pushAndroid", function(request, response) {

  var user = request.user;
  var params = request.params;
  var someKey = params.someKey
  var data = params.data

  var recipientUser = new Parse.User();
  recipientUser.id = someKey;

  var pushQuery = new Parse.Query(Parse.Installation);
  pushQuery.equalTo("userID", someKey);


  Parse.Push.send({
    where: pushQuery, // Set our Installation query
    data: {
       alert: data
    }
}, { success: function() {
      console.log("#### PUSH OK");
  }, error: function(error) {
      console.log("#### PUSH ERROR" + error.message);
  }, useMasterKey: true});

  response.success('success');
});

在 xcode 项目中这样做是为了发送推送通知

     // Send Push notification
        let pushStr = "@\(PFUser.current()![USER_USERNAME]!) | \n\(self.lastMessageStr)"


        let data = [ "badge" : "Increment",
                     "alert" : pushStr,
                     "sound" : "bingbong.aiff",

            ] as [String : Any]
        let request = [
            "someKey" : self.userObj.objectId!,
            "data" : data

            ] as [String : Any]
        PFCloud.callFunction(inBackground: "push", withParameters: request as [String : Any], block: { (results, error) in
            if error == nil {
                print ("\nPUSH SENT TO: \(self.userObj[USER_USERNAME]!)\nMESSAGE: \(pushStr)\n")
            } else {
                print ("\(error!.localizedDescription)")
            }
        })
