我有一个设置的服务器，当我设置构造函数时，我传入了一个地图。
当服务器加载时，我调用一个名为getDaily的函数，它返回应该看的数据，但仅在命令控制台中。
在json的http请求中，它似乎只做一个浅拷贝，返回
{
"summary": {},
"icon": {},
"data": {}
}
该功能如下所示：
@ApiMethod(method:'GET', path: 'daily')
Map<String, Object> getDaily(){
return myWeather.daily;
}
为什么不返回数据？这是它应该返回的内容。

两次都会调用完全相同的函数。
编辑在github上查找RPC时https://github.com/dart-lang/rpc/blob/master/test/src/parser/api_common_method_test.dart它实际上没有提到做Map<String, Object>所以我认为这可能是RPC的无效返回值？< / p>
