初学Golang：Gin 框架中文文档教程
// Binding from JSON type Login struct {User string `form:"user" json:"user" binding:"required"`
Password string `form:"password" json:"password" binding:"required"`
}
func main() {
router := gin.Default()
// 绑定JSON的例子 ({"user": "manu", "password": "123"})
router.POST("/loginJSON", func(c *gin.Context) {
var json Login
if c.BindJSON(&json) == nil {
if json.User == "manu" && json.Password == "123" {
c.JSON(http.StatusOK, gin.H{"status": "you are logged in"})
} else {
c.JSON(http.StatusUnauthorized, gin.H{"status": "unauthorized"})
}
}
})
// 绑定普通表单的例子 (user=manu&password=123)
router.POST("/loginForm", func(c *gin.Context) {
var form Login
// 根据请求头中 content-type 自动推断.
if c.Bind(&form) == nil {
if form.User == "manu" && form.Password == "123" {
c.JSON(http.StatusOK, gin.H{"status": "you are logged in"})
} else {
c.JSON(http.StatusUnauthorized, gin.H{"status": "unauthorized"})
}
}
})
// 绑定多媒体表单的例子 (user=manu&password=123)
router.POST("/login", func(c *gin.Context) {
var form LoginForm
// 你可以显式声明来绑定多媒体表单：
// c.BindWith(&form, binding.Form)
// 或者使用自动推断:
if c.Bind(&form) == nil {
if form.User == "user" && form.Password == "password" {
c.JSON(200, gin.H{"status": "you are logged in"})
} else {
c.JSON(401, gin.H{"status": "unauthorized"})
}
}
})
// Listen and serve on 0.0.0.0:8080
router.Run(":8080")
}
