问题
我是你的中文翻译助手，以下是你要翻译的内容：
我是Go语言的新手，在修改数据结构时遇到了问题。在这段代码中，我想根据请求体的值修改变量To，该如何做到？
请求体：{"phone": "1989876787"}
type Payload struct {
MessagingProduct string `json:"messaging_product"`
To string `json:"to"`
}
func Send(c *gin.Context) {
data := Payload{
MessagingProduct: "sms",
To: "", // 从请求体中修改这个值
}
jsonStr, _ := json.Marshal(data)
fmt.Println("请求体", string(jsonStr))
}

使用gin框架，您可以使用绑定函数。
type Payload struct {
Phone string `json:"phone"`
}
func Send(c *gin.Context) {
...
var payload Payload
if err := c.ShouldBindJSON(&payload); err != nil {
// 处理绑定错误
}
data := Payload{
MessagingProduct: "sms",
To: payload.Phone,
}
...
}
英文:
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,
}
...
}
