如何在Golang中将[] byte XML转换为JSON输出

go

有没有办法在Golang中将XML([] byte)转换为JSON输出?

我有下面的功能在哪里body[]byte但我想经过一些操作后将此XML响应转换为JSON。我已经尝试Unmarshalxml打包但没有成功:

// POST 
func (u *UserResource) authenticateUser(request *restful.Request, response *restful.Response) {
    App := new(Api)
    App.url = "http://api.com/api"
    usr := new(User)
    err := request.ReadEntity(usr)
    if err != nil {
        response.AddHeader("Content-Type", "application/json")
        response.WriteErrorString(http.StatusInternalServerError, err.Error())
        return
    }

    buf := []byte("<app version=\"1.0\"><request>1111</request></app>")
    r, err := http.Post(App.url, "text/plain", bytes.NewBuffer(buf))
    if err != nil {
        response.AddHeader("Content-Type", "application/json")
        response.WriteErrorString(http.StatusInternalServerError, err.Error())
        return
    }
    defer r.Body.Close()
    body, err := ioutil.ReadAll(r.Body)
    response.AddHeader("Content-Type", "application/json")
    response.WriteHeader(http.StatusCreated)
//  err = xml.Unmarshal(body, &usr)
//  if err != nil {
//      fmt.Printf("error: %v", err)
//      return
//  }
    response.Write(body)
//  fmt.Print(&usr.userName)
}

我也在使用Go-restful软件包

如果需要使用未知结构将XML文档转换为JSON,则可以使用goxml2json

范例:

import (
  // Other imports ...
  xj "github.com/basgys/goxml2json"
)

func (u *UserResource) authenticateUser(request *restful.Request, response *restful.Response) {
  // Extract data from restful.Request
  xml := strings.NewReader(`<?xml version="1.0" encoding="UTF-8"?><app version="1.0"><request>1111</request></app>`)

  // Convert
    json, err := xj.Convert(xml)
    if err != nil {
        // Oops...
    }

  // ... Use JSON ...
}
