接口：

//POST请求 返回json 接口传参json
r.POST("/postJson", controller.PostUserInfo)

1.定义结构体

//定义结构体
type Search struct {Id   intName string
}

2.结构体传参

//结构体传参
func PostUserInfo(c *gin.Context) {search := &Search{}err := c.BindJSON(&search)if err == nil {ReturnSucess(c, 200, "请求成功",search, 1)return}ReturnError(c, 500, gin.H{"err": err}, search, 1)
}

3.完整代码

package controllerimport "github.com/gin-gonic/gin"//定义结构体
type Search struct {Id   intName string
}//结构体传参
func PostUserInfo(c *gin.Context) {search := &Search{}err := c.BindJSON(&search)if err == nil {ReturnSucess(c, 200, "请求成功",search, 1)return}ReturnError(c, 500, gin.H{"err": err}, search, 1)
}

4.接口测试及返回
