问题内容

我正在尝试处理从 API 返回的一些 JSON 数据。然而，它并不完全是一个简单的结构。它有一堆嵌套的键/值。我想将其解组为 Go 结构。

使用 go 有简单的方法吗？

     }
    }
   }

解决方法

这里有一个简单的方法：

type Header struct {
    Key      string `json:"key"`
    Value    string `json:"value"`
    RawValue string `json:"raw_value"`
}

type Trailer = Header

type Body struct {
    Truncated bool   `json:"truncated"`
    AsString  string `json:"as_string"`
}

type Request struct {
    Headers  []Header  `json:"headers"`
    Body     Body      `json:"body"`
    Trailers []Trailer `json:"trailers"`
}

type Response = Request

type HttpBufferedTrace struct {
    HttpBufferedTrace struct {
        Request  Request  `json:"request"`
        Response Response `json:"response"`
    } `json:"http_buffered_trace"`
}

func main() {

    h := HttpBufferedTrace{}

    json.Unmarshal([]byte(jsonStr), &h)

    fmt.Println(h)
}
