Javascript 无法在解析云函数中从httpRequest检索结果

我在一个云函数中运行一个Parse-httpRequest，我从另一个解析作业调用它。我不知道如何从我在云作业中调用的云函数中检索结果值/成功值

以下是云函数的代码：

Parse.Cloud.define("maps_request", function(request, response) {
  var maps_url = 'http://maps.googleapis.com/maps/api/directions/json';
  var origin = request.params.origin;
  var destination = request.params.destination;
  var waypoint = "via:" + request.params.waypoint;
  Parse.Cloud.httpRequest({
    url: maps_url,
    params: {
      origin: origin,
      destination: destination,
      waypoints: waypoint,
      optimizeWaypoints: true,
      durationInTraffic: true
    },
    success: function(directions) {
      var time = directions.data['routes'][0]['legs'][0]['duration']['value']
      time = time / 60.00
      response.success(time)
    },
    error: function(error) {
      response.error("Shit broke.")

    }
  })
});

以及云作业中调用的代码：

var promise = Parse.Promise.as();
      promise = Parse.Cloud.run('maps_request', {
        origin: String(driverOriginAddress + " " + driverOriginZip),
        destination: String(driverDestinationAddress + " " + driverDestinationZip),
        waypoint: String(driverDestinationAddress + " " + driverDestinationZip)
      }, {
        success: function(results) {
          console.log("Results: " + results)
        },
        error: function(){
          console.log("Error")
        }
      })
      console.log(promise)

解析日志显示了我希望从云函数得到的确切结果，但我得到了以下结果： “{U resolved]：false，{U rejected]：false，{U resolvedCallbacks:[]，“{U rejectedCallbacks:[]}”

我已经尝试了大约50个不同的版本来解决这个问题。任何帮助都将不胜感激

这是云功能代码的另一个版本：

Parse.Cloud.define("maps_request", function(request, response) {
  var maps_url = 'http://maps.googleapis.com/maps/api/directions/json';
  var origin = request.params.origin;
  var destination = request.params.destination;
  var waypoint = "via:" + request.params.waypoint;
  var test = []
  Parse.Cloud.httpRequest({
    url: maps_url,
    params: {
      origin: origin,
      destination: destination,
      waypoints: waypoint,
      optimizeWaypoints: true,
      durationInTraffic: true
    },
    success: function(directions) {
      var time = directions.data['routes'][0]['legs'][0]['duration']['value']
      time = time / 60.00
      test.push(time)
    },
    error: function(error) {
      console.log("Error")
    }
  }).then(function() {
    response.success(test[0])
  }, function (error) {
    response.error("Error2")
  })
});

电话：

var test = Parse.Cloud.run('maps_request', {
        origin: String(driverOriginAddress + " " + driverOriginZip),
        destination: String(driverDestinationAddress + " " + driverDestinationZip),
        waypoint: String(driverDestinationAddress + " " + driverDestinationZip)
      })
      console.log("Test: " + test)

httpResponse显示了正确的值，但仍然无法访问它们或分配给变量。

听起来不错-您正在将“promise”的值记录到控制台。您必须实际解析（）promise，让它调用您的云函数等等。

无需包装

Parse.Cloud.run（）

在承诺中，因为它已返回承诺

同样，在第二个示例中，您调用云函数，就好像它是一个sync调用，而不是async，并查看承诺而不是您想要的结果

试试这个：

Parse.Cloud.run('maps_request', {
  origin: String(driverOriginAddress + " " + driverOriginZip),
  destination: String(driverDestinationAddress + " " + driverDestinationZip),
  waypoint: String(driverDestinationAddress + " " + driverDestinationZip)
}).then(function (result) {
  // we have the result of the cloud function here, just log it for now
  console.log("Test:", result);
}, function (error) {
  // uh oh!
  console.log(error);
});

谢谢你的回复。我如何/在哪里解决这个承诺？添加了另一个版本的代码，我一直在使用，返回类似的响应。
