sur*_*ray 7 arrays json go

我试图从json数组中获取每个json对象.我通过http帖子获得这些数据.

我知道我的数据会是什么样子:

   {
    "array":[
       {
          "entity_title":"University of Phoenix", 
          "entity_org_name":"CS Club",
          "possible_user_name":"Johnny Ive",
          "posibble_user_email":"Johhny.Ive@uop.edu",
          "user_position_title":"President",
          "msg_body_id":4
       },
      {
          "entity_title":"University of San Francisco", 
          "entity_org_name":"Marketing club",
          "possible_user_name":"steve jobs",
          "posibble_user_email":"steven.job@uop.edu",
          "user_position_title":"Student",
          "msg_body_id":5
      }
    ]
  }

我的示例代码和我的结构看起来像这样:

    type MsgCreateUserArray struct {
         CreateUser []MsgCreateUserJson `json:"createUserArray"`
    }
    type MsgCreateUserJson struct {
        EntityTitleName string  `json:"entity_title_name"`
        EntityOrgName   string  `json:"entity_org_name"`
        PossibleUserName string `json:"possible_user_name"`
        PossibleUserEmail   string  `json:"possible_user_email"`
        UserPositionTitle   string  `json:"user_position_title"`
        MsgBodyId       string  `json:"msg_body_id, omitempty"` 
    }


func parseJson(rw http.ResponseWriter, request *http.Request) {
    decodeJson := json.NewDecoder(request.Body)

    var msg MsgCreateUserArray
    err := decodeJson.Decode(&msg)

    if err != nil {
        panic(err)
    }
    log.Println(msg.CreateUser)
}

func main() {
    http.HandleFunc("/", parseJson)
    http.ListenAndServe(":1337", nil)
}

我不知道如何迭代json数组并获取json对象,然后只使用json对象.
