Question

我已将所有用户的位置保存在安装对象中。我有另一个名为locationObject的对象，当当前用户发送当前位置时会更新。当它发生时，我想将他当前的位置与所有其他保存的位置进行比较，并向附近的用户发送推送通知。这是我的代码，但这似乎不起作用。

//this code should run when the locationObject is updated
Parse.Cloud.afterSave("locationObject", function (request) {
    var geoPoint = request.object.get("myCurrentLocation");
    var pushQuery = new Parse.Query(Parse.Installation);
    pushQuery.near("significantLocationUpdate", geoPoint);
    pushQuery.limit(100);
    pushQuery.find({
        success: function(results) {
            if (results.length > 0) {
                //console.log(JSON.stringify(results));
                for (i = 0; i < results.length; 1++) {
                    Parse.Push.send({
                        where: pushQuery,
                        data: {
                            alert: "some user is nearby" 
                        }
                    }, {
                        success: function() {
                            console.log("push was successfull")
                        },
                        error: function(error) {
                            console.log("sending push failed")// Handle error
                        }
                    });
                }
            } else {
                console.log("failure");
            }
        },
        error: function (error) {
            console.log("error");
        }
    });
});

这就是我重新构建代码的方式。它有效。感谢Paulw11

Parse.Cloud.afterSave("locationObject", function (request) {
    var geoPoint = request.object.get("myCurrentLocation");
    var pushQuery = new Parse.Query(Parse.Installation);
    pushQuery.near("significantLocationUpdate", geoPoint);
    pushQuery.limit(100);

    Parse.Push.send({
        where: pushQuery,
        data: {
            alert: "some user is nearby"
        }
    }, {
        success: function() {
            console.log("push was successful");
        },
        error: function(error) {
            console.log("sending push failed")// Handle error
        }
    });
});
