body: {"phone": "1989876787"}

type Payload struct {
    MessagingProduct string   `json:"messaging_product"`
    To               string   `json:"to"`
}

func Send(c *gin.Context) {
    data := Payload{
        MessagingProduct: "sms",
        To: "", //modify this from req body
    }
    jsonStr, _ := json.Marshal(data)
    fmt.Println("req body", string(jsonStr))
}

CodePudding user response：

Using gin framework, You can use binding function.

type Payload struct {
    Phone string   `json:"phone"`
}

func Send(c *gin.Context) {
...
   var payload Payload
   if err := c.ShouldBindJSON(&payload); err != nil {
       // handling error binding
   }
   data := Payload{
      MessagingProduct: "sms",
      To:  paylod.Phone,
   }
...
}
