如何处理自定义解析json

[JasonHezz]

我使用dart-json-mapper做json解析 避免重复代码 在生成代码中我想替换如下代码

final value = T.fromJson(_result.data) ;

成

final value = JsonMapper.deserialize<T>(_result.data);

应该如何处理比较好

目前还没有很好的插件机制来实现 这个需要修改generator的代码

https://github.com/trevorwang/retrofit.dart/blob/master/generator/lib/src/generator.dart 搜索 fromJ'son

欢迎PR

我的方案是在RestApi 增加String parser

parser 为JsonSerializable则是生成旧模式

parse为DartJsonMapper则生成JsonMapper.deserialize

默认值为JsonSerializable

不知道这个方案可行吗 如果可行 我会尝试在周末提交PR

[trevorwang]

OK. parser考虑使用枚举类型

Can someone explain me what this ticket exactly does? Or is there documentation available

[JasonHezz]

@vanlooverenkoen I'm sorry for that .

This is a discussion about how to custom deserialize json. I use dart json mapper and I prefer generate code

final value = JsonMapper.deserialize<T>(_result.data);

rather than

final value = T.fromJson(_result.data) ;

That's the PR address. If you want to use dart json mapper too. Try code blow

@RestApi(
  baseUrl: 'http://xx/',
  parser: Parser.DartJsonMapper, 
)
abstract class RestClient {
}

But remember this only support deserialize , and @Body is not working because I have few time now. Hopefully I can finish that in next weeks.
