Question

CloudCode功能是：

Parse.Cloud.define('addFriend', function(request, response) {
   var userId = request.params.userId;

   var User = Parse.Object.extend('_User'),
       user = new User({ objectId: userId });

   var currentUser = request.user;

   var relation = user.relation("Friends");
   relation.add(currentUser);

   Parse.Cloud.useMasterKey();
   user.save().then(function(user) {
       response.success(user);
   }, function(error) {
    response.error(error)
   });
});

当我通过PFCloud调用从Xcode调用它时....我在控制台中收到下一个错误：

[Error]: ReferenceError: parent is not defined
at e.n.value (Parse.js:13:7510)
at main.js:10:14 (Code: 141, Version: 1.8.2)

这意味着实际问题是关系没有父关系。它应该已经有了用户＆＃39;变量作为父变量，因为我正在调用user.relation（＆＃34; Friends＆＃34;），这是文档所说的内容：＆＃34;你很少应该手动设置父亲，因为你是很可能会调用Parse.Object.relation（＆＃39; key＆＃39;）。＆＃34;这就是我在做的事。

更新

即使这段代码也会出现同样的错误：

 Parse.Cloud.define("addFriend", function(request, response) {
    Parse.Cloud.useMasterKey();

    var currentUser = request.user;
    var relation = currentUser.relation("Friends");
    relation.add(currentUser);
});

更新2：

用户JSON

{
   "FriendRequests": {
    "__type": "Relation",
    "className": "_User"
},
   "Friends": {
    "__type": "R‌elation",
    "className": "_User"
},
"createdAt": {
    "__type": "Date",
    "iso": "2015-09-10T17:29‌:03.181Z"

   "iso": "2015-09-10T17:29:03.181Z"
 },
 "username": "bogdan12",

}

关系JSON

{
    "__type": "Relation",
    "className": "_User"
}

尝试更换：

var User = Parse.Object.extend('_User'),
    user = new User({ objectId: userId });

使用：

    user = new Parse.User.createWithoutData(userId);

编辑：

它适用于我...这是我尝试过的：

云：

Parse.Cloud.define('addFriend', function(request, response)
{
    var currentUser = request.user;
    var userId = request.params.userId;
    var user = new Parse.User.createWithoutData(userId);

    var relation = user.relation("Friends");
    relation.add(currentUser);

    Parse.Cloud.useMasterKey();
    user.save().then(function(user) {
        response.success(user);
    }, function(error) {
        response.error(error)
    });
});

客户：

[PFCloud callFunctionInBackground:@"addFriend" withParameters:@{@"userId":@"s8BMHtnqSZ"} block:^(id object, NSError *error) {
    if (!object || error) {
        LogError(error, @"Calling addFriend failed.");
    } else {
        LogInfo(@"Calling addFriend succeeded.");
    }
}];

解析CloudCode功能不起作用。调用它时出错
