如何使用Dart Serialization获取JSON序列化字符串

对于以下代码

var address = new Address();
address.street = 'N 34th';
address.city = 'Seattle';
var serialization = new Serialization()
 ..addRuleFor(address);
String output = serialization.write(address);

我如何获得像这样的json输出：

address: {'street':'N 34th','city':'Seattle'}

以上代码产生的输出如下：

{"roots":[{"__Ref":true,"rule":3,"object":0}],"data":[[],[],[["Seattle","N 34th"]]],"rules":"{\"roots\":[{\"__Ref\":true,\"rule\":1,\"object\":0}],\"data\":[[],[[{\"__Ref\":true,\"rule\":4,\"object\":0},{\"__Ref\":true,\"rule\":3,\"rule\":5,\"rule\":6,\"object\":0}]],[[],[\"city\",\"street\"]],[[]],\"rule\":2,\"object\":1},\"\",\"object\":2},\"rule\":7,[\"Address\"]],\"rules\":null}"}

解决方法

您可以使用 JsonObject for Dart,将其添加到您的pubspec.yaml文件中,然后运行pub install(工具 – > Pub Install)

dependencies:
  json_object: 
    git: git://github.com/chrisbu/dartwatch-JsonObject.git

然后更改你的代码调用objectToJson：

import 'package:json_object/json_object.dart';

var address = new Address();
address.street = 'N 34th';
address.city = 'Seattle';
String output =  objectToJson(address);

请注意,objectToJson需要镜像支持(反射功能),该镜像只支持Dart VM.截至2012-12-20,dart2js不起作用.
