如何读取json格式的数据?

I have a function in which I have to post the data to a url in json format. When I send the data then it will give response in json. But there it will showing me like:-

Output given by code

&{200 OK 200 HTTP/1.1 1 1 
map[Content-Type:[application/json] X-Request-Id:[CgiFzq669pAYzRABGBAiCQiRtaznvJffAg] 
Keep-Alive:[timeout=60] 
Vary:[Accept-Encoding] 
X-Content-Type-Options:[nosniff] 
X-Download-Options:[noopen] 
X-Permitted-Cross-Domain-Policies:[none] 
Strict-Transport-Security:[max-age=631152000] 
X-Frame-Options:[DENY] 
X-Xss-Protection:[1; mode=block] 
Date:[Tue, 11 Dec 2018 09:35:22 GMT] 
Access-Control-Allow-Headers:[Content-Type, Authorization, Accept] 
Access-Control-Allow-Origin:[*] 
Access-Control-Expose-Headers:[Link]] 0xc420442080 -1 [] false true map[] 0xc42023e100 0xc4200e0d10}

code is :-

func Token(c *gin.Context) {
   code := c.Query("code")
   responseToken :=TokenResponse{}
   token := models.PostToken{
     ClientID:     "appllication Id",
     ClientSecret: "applicationSecreteId",
     Code:         "code",
     RedirectUri:  c.Request.Host + c.Request.URL.RequestURI(),
   }
   bindData, err := json.Marshal(token)
   if err != nil {
     panic(err)
   }
   var jsonStr = []byte(string(bindData))
   url :="https://connect.squareup.com/oauth2/token"
   req, err := http.Post(url, "application/json", bytes.NewBuffer(jsonStr))
   fmt.Println(req, err)
}

type TokenResponse struct {
  Token      string `json:"access_token"`
  Type       string `json:"token_type"`
  ExpiresAt  string `json:"expires_at"`
  MerchantId string `json:"merchant_id"`
}

Expected output:-

{
  "access_token": "token",
  "token_type": "bearer",
  "expires_at": "2019-01-10T08:20:59Z",
  "merchant_id": "id"
}

But when I hit "https://connect.squareup.com/oauth2/token" url in postman then it will give me json but In golang code it will not showing any json it will return the above data. Can anyone tell me that how i will get the json data from above response?

    Try this,

    respBody, Err := ioutil.ReadAll(req.Body)
    
    fmt.Println(string(respBody))
    
    var temp TokenResponse
    
    err := json.Unmarshal(respBody, &temp)
