   }

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)
}
