我有一個函數，我必須將數據以 json 格式發布到 url。當我發送數據時，它會以 json 格式給出響應。但它會向我展示：-代碼給出的輸出&{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}代碼是：-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"`}預期輸出：-{  "access_token": "token",  "token_type": "bearer",  "expires_at": "2019-01-10T08:20:59Z",  "merchant_id": "id"}但是當我在郵遞員中點擊“ https://connect.squareup.com/oauth2/token ” url 時它會給我 json 但在 golang 代碼中它不會顯示任何 json 它將返回上述數據。誰能告訴我如何從上面的響應中獲取 json 數據？
