将解析对象传入云代码函数

Question

我有一个创建 GuestlistInvite 的云代码函数

对象。它需要一个 phoneNumber、一个 guestlist 对象和一个 guest 对象。

我这样调用函数：

Parse.Cloud.run('createGuestlistInviteForExistingUser', {
   phoneNumber: phoneNumber,
   guestlist: guestlist,
   guest: user
   }).then(function(guestlistInvite) {
      response.success(successfully created guestlistInvite');
 });

客人名单和用户都是指针。但是在我的日志中我收到一个错误：

Result: Error: Parse Objects not allowed here

知道为什么会这样吗？

Parse.Cloud.define('createGuestlistInviteForExistingUser', function(request, response) {

  var phoneNumber = request.params.phoneNumber;
  var guestlist = request.params.guestlist;
  var guest = request.params.guest;

  var guestlistInvite = new Parse.Object("GuestlistInvite");

  guestlistInvite.save({
    phoneNumber: phoneNumber,
    Guestlist: guestlist,
    Guest: guest,
    checkInStatus: false,
    response: 0
  }).then(function(guestlistInvite) {
    console.log('guestlistInvite for existing user was created');
    response.success(guestlistInvite);
  }, function(error) {
    response.error('guestlistInvite was not saved');
  });

});

您不能发送整个 PFObject 作为请求参数来调用 Cloud Functions。

但是您可以简单地通过将 PFObject 的 objectId 作为请求参数传递然后在云代码中编写代码以从云代码中的 objectId 获取对象来实现该功能。

下面是使用 promises 的云代码的片段：

Parse.Cloud.define("myFunction", functoin(request, response)
{
    var MyObject = Parse.Object.extend("MyObjectClass"); //You can put this at the top of your cloud code file so you don't have to do it in every function
    var myObject = new MyObject(); 
    var myObjectId = request.params.myObjectId;

    myObject.id = myObjectId;
    myObject.fetch().then
    (
        function( myObject )
        {
            //do stuff with it
        },
        function( error )
        {
            response.error("There was an error trying to fetch MyObjectClass with objectId " + myObjectId + ": " + error.message);
        }
    );
});
