如何获取JSON序列化字符串使用Dart序列化 [英] How to get JSON serialized string using Dart Serialization

问题描述

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）; 
  

如何获得如下的json输出：

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

上述代码生成的输出如下：

  {roots： [[]，[]，[]，[[Seattle，N 34th]]]，[数据]：[{__Ref：true，rule：3，object：0} rules：{\roots \：[{\__ Ref\：true，\rule\：1，\object \：0}]，\ data \：[[]，[[{\__ Ref\：true，\rule\：4，\object \：0}，{\__ Ref\\ \\：true，\rule\：3，\object \：0}，{\__ Ref\：true，\rule\：5，\ object \：0}，{\__ Ref\：true，\rule\：6，\object \：0}]，[[]，[] \city\，\street\]，[[]]，[[]]，[[]]，[[{\__ Ref\：true，\ \：2，\object \：0}，{\__ Ref\：true，\rule\：2，\object \：1} \\\，{\__ Ref\：true，\rule\：2，\object \：2}，{\__ Ref\：true， \\rule \：7，\object \：0}]]，[\Address\]]，\rules\：null}} 
  
 
 
解决方案
您可以使用 JsonObject for Dart ，将它添加到您的 pubspec.yaml 文件，然后运行 pub install （工具 - > Pub安装）
 依赖项：
 json_object：
 git：git：//github.com/chrisbu/dartwatch-JsonObject.git 
  
然后改变你的代码调用 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 需要镜像支持反射能力），它只能在Dart VM中工作。它不适用于2012-12-20的dart2js。
 
For the following code
var address = new Address();
address.street = 'N 34th';
address.city = 'Seattle';
var serialization = new Serialization()
 ..addRuleFor(address);
String output = serialization.write(address);
How do i get a json output like this:
address: {'street':'N 34th', 'city':'Seattle'}
Output generated by above code is as follows:
{"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,\"object\":0},{\"__Ref\":true,\"rule\":5,\"object\":0},{\"__Ref\":true,\"rule\":6,\"object\":0}]],[[],[],[\"city\",\"street\"]],[[]],[[]],[[]],[[{\"__Ref\":true,\"rule\":2,\"object\":0},{\"__Ref\":true,\"rule\":2,\"object\":1},\"\",{\"__Ref\":true,\"rule\":2,\"object\":2},{\"__Ref\":true,\"rule\":7,\"object\":0}]],[\"Address\"]],\"rules\":null}"}

解决方案
You can use the JsonObject for Dart, add this to your pubspec.yaml file and then run pub install (Tools -> Pub Install)
dependencies:
  json_object: 
    git: git://github.com/chrisbu/dartwatch-JsonObject.git
And then change your code to call objectToJson :
import 'package:json_object/json_object.dart';

var address = new Address();
address.street = 'N 34th';
address.city = 'Seattle';
String output =  objectToJson(address);
Note that objectToJson requires mirrors support (the reflection capabilities) which only work in Dart VM at the moment. It does not work in dart2js as of 2012-12-20.
