javascript - parse.com 云代码问题，但在 javascript 中运行完美

Question

我在这段不想工作的代码上浪费了 8 个小时

在 localhost 和 javascript 上它运行良好，但在 parse.com 云代码中我得到一个变量未定义。

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

var price;

function getPrices(stockPrice){
console.log(stockPrice);

var PriceTick = Parse.Object.extend("StockPrices");
var queryInstal = new Parse.Query(Parse.Installation);

var queryLess = new Parse.Query(PriceTick);
var queryMore = new Parse.Query(PriceTick);

queryLess.equalTo("Position","Less");
queryLess.greaterThan("Price", stockPrice);

console.log(PriceTick) // RETURNS UNDEFINED
console.log(queryInstal) // RETURNS UNDEFINED

因为那些返回未定义的代码的其余部分无法工作......奇怪的是这在没有云代码的本地主机上工作得很好

queryLess.find({
success: function(results) {
//Less than

console.log("found less");

 if (results.length) {

for (var i = 0; i < results.length; i++) { 
var object = results[i]

var devicetoken = object.get('devicetoken');
var objID = object.get('objectId');

console.log("Got Less");
queryInstal.equalTo('deviceToken', devicetoken);
queryInstal.equalTo('deviceType', 'ios');

Parse.Push.send({
  where: queryInstal, // Set our Installation query
  data: {
    alert: "The price is now: "+stockPrice
  }
}, {
  success: function() {
    // Push was successful
          object.destroy({});


  },
  error: function(error) {
    // Handle error
  }
});
}
}},
 error: function(error) {
  alert("Error: " + error.code + " " + error.message);
 }
});




Parse.Cloud.httpRequest({
url: "example.php",
dataType: 'json',
type: 'GET',
success: function(data) {
 price = data.data.Response.price;
 response.success("yes")
 getPrices(price);

},
error: function(data) {
  response.error('Request failed with response code ' + data.status);

}
}); });

你必须使用Parse.Query(ClassName)，其中 ClassName 是 Parse.Object 子类的名称字符串或实例:
