1、ShouldBindJSON

package mainimport ("github.com/gin-gonic/gin""net/http"
)type User struct {Name   string `json:"name"`Gender string `json:"gender"`Age    int    `json:"age"`
}func getUser(c *gin.Context) {var userInfo Usererr := c.ShouldBindJSON(&userInfo)if err != nil {c.JSON(http.StatusOK, gin.H{"message": "参数错误"})return}c.JSON(http.StatusOK, userInfo)
}func main() {router := gin.Default()router.GET("/user", getUser)router.Run(":9090")
}

2、ShouldBindQuery

package mainimport ("github.com/gin-gonic/gin""net/http"
)type UserInfo struct {Name   string `json:"name" form:"name"`Gender string `json:"gender" form:"gender"`Age    string `json:"age" form:"age"`
}func getUserInfo(c *gin.Context) {var userInfo UserInfoerr := c.ShouldBindQuery(&userInfo)if err != nil {c.JSON(http.StatusOK, gin.H{"message": "参数有误"})return}c.JSON(http.StatusOK, userInfo)
}func main() {router := gin.Default()router.POST("/user", getUserInfo)router.Run("9090")
}

3、ShouldBindUri

package mainimport ("github.com/gin-gonic/gin""net/http"
)func bindUri(c *gin.Context) {type User struct {Name string `json:"name" uri:"name"`Age  int    `json:"age" uri:"age"`}var user Userc.ShouldBindUri(&user)c.JSON(http.StatusOK, user)
}func main() {router := gin.Default()router.GET("/uri/:name/:age", bindUri)router.Run(":9000")
}

4、ShouldBind

package mainimport ("github.com/gin-gonic/gin""net/http"
)type Students struct {Name   string `json:"name" form:"name"`Gender string `json:"gender" form:"gender"`Age    int    `json:"age" form:"age"`
}func getStudent(c *gin.Context) {var userInfo Studentserr := c.ShouldBind(&userInfo)if err != nil {c.JSON(http.StatusOK, gin.H{"message": "参数错误"})return}c.JSON(http.StatusOK, userInfo)
}func main() {router := gin.Default()router.GET("/user", getStudent)router.Run(":9000")
}
