使用Golang从DuckDuckGo中解码JSON

Question

我一直在使用用于DuckDuckGo的Go库，除了一件事外，它一直运行得很好。在"RelatedTopics“部分。通常，它看起来是这样的：

然而，有时在"RealtedTopics“一节中，会出现一系列”主题“，其中包含许多”结果“，并出现了该主题的”名称“。

如果这没什么意义的话我很抱歉。这方面的一个很好的例子是当你搜索博士。

如何扩展库以便访问这些“主题”？我想不出用json.Unmarshal (库所用的方法)来完成它的方法。

致以敬意，

Answer 1

似乎主题中包含了一个片段Topics []Topic。

type Icon struct {
  URL string
  Height string
  Width string
}

type Topic struct {
  Result string
  Icon Icon
  FirstURL string
  Text string
  Topics []Topic `json:",omitempty"`
}

type RootObj struct {
 RelatedTopics []Topic
}
