合并重复字段的结果

Question

我有一个JSON文件，如下所示：

{
    "name1": 
    {
        "fields": 
        {
            "Name": 
            {
                "type": "STRING"
            },
            "Email":
            {
                "type": "STRING"
            },
            "Password":
            {
                "type": "STRING"
            },
            "role":
            {
                "type": "STRING"
            }
        }
    },
    "name2":
    {
        "fields": 
        {
            "url":
            {
                "type": "STRING"
            }
        }
    },
    "name1":
    {
        "fields": 
        {                        
            "Address":
            {
                "type": "STRING"
            }
        }
    }
}

我想迭代它，如果有一个已存在的名称，我想合并这些字段;这是我的代码：

var DBSchema = [];
async.each(Object.keys(config), function(key) {
    var currentObject = config[key];
    var DBSchemaTemp = [];
    for (var field in currentObject.fields) {
        if (currentObject.fields.hasOwnProperty(field)) {
            DBSchemaTemp[field] = {AttributeName: field,
                AttributeType: currentObject.fields[field].type
            }
        }
    }
    var arrayInSchema = DBSchema[key];

    if (typeof arrayInSchema === 'undefined') {
        DBSchema[key] = [];
        DBSchema[key].push(DBSchemaTemp);
    } else {
        DBSchema[key].concat(DBSchemaTemp);
    }
}, function(err) {
    console.log(err);
});

for (variable in DBSchema) {
    console.log(variable);
    console.log(DBSchema[variable]);
}

我想要的输出是：

{ 
    name1: [ Name: { AttributeName: 'Name', AttributeType: 'STRING' },
 Email: { AttributeName: 'Email', AttributeType: 'STRING' },
 Password: { AttributeName: 'Password', AttributeType: 'STRING' },
 role: { AttributeName: 'role', AttributeType: 'STRING' }   Address: { AttributeName: 'Address', AttributeType: 'STRING' } ] 
 name2:  [ url: { AttributeName: 'url', AttributeType: 'STRING' } ]  
}

但我的代码返回：

 { name1: [ [   Address: { AttributeName: 'Address', AttributeType:  'STRING' } ] ] name2: [ [ url: { AttributeName: 'url', AttributeType:  'STRING' } ] ] }

请注意;由于某种原因，它也增加了双[[]]！
