Parse.com:获取UserCannotBeAlteredWithoutSessionError

Question

我有一个Angular服务,它接受一个roleId和userId,并将用户分配给该角色,并在User中为该角色创建一个指针.

app.service('CRUD', function () {
    this.addUserToRole = function (roleId, userId) {
        // first we have to find the role we're adding to
        var query = new Parse.Query(Parse.Role);
        return query.get(roleId, {
            success: function (role) {
                // then add the user to it
                var Database = Parse.Object.extend("User");
                var query = new Parse.Query(Database);
                console.log(role);
                return query.get(userId, {
                    success: function (user) {
                        console.log(user);
                        role.getUsers().add(user);
                        role.save();

                        // now we need to tell the user that he has this role
                        console.log(user);
                        user.attributes.role.add(role);
                        user.save();
                        return user;
                    },
                    error: function (err) {
                        return err;
                    }
                });
            },
            error: function (err) {
                console.log(err);
            }
        });
    }
});

我得到{"code":206,"error":"Parse::UserCannotBeAlteredWithoutSessionError"}的user.save();

经过一番研究,我来到了这个网站.他将此代码段用作JS SDK示例:

Parse.Cloud.run('modifyUser', { username: 'userA' }, {
  success: function(status) {
    // the user was updated successfully
  },
  error: function(error) {
    // error
  }
});

并提到一些关于useMasterKey()功能的事情.

我仍然不确定如何修复此错误.

Answer 1

加

Parse.Cloud.useMasterKey();

在你的功能开始.
