合并重复字段的结果

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" } } } } 

我想遍历它，如果有一个已经存在的名称我想合并字段; 这里是我的代码：

 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]); } 

我期望的输出是：

 { 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[[]]！
