Cookie

Cookie example (opens new window)

Basic Usage

• GetCookie(key string)
• SetCookie(name string, value string, others ...interface{})

Example:

type MainController struct {
	web.Controller
}

func (ctrl *MainController) PutCookie() {
	// put something into cookie,set Expires time
	ctrl.Ctx.SetCookie("name", "web cookie", 10)

	// web-example/views/hello_world.html
	ctrl.TplName = "hello_world.html"
	ctrl.Data["name"] = "PutCookie"
	_ = ctrl.Render()
}

func (ctrl *MainController) ReadCookie() {
	// web-example/views/hello_world.html
	ctrl.TplName = "hello_world.html"
	ctrl.Data["name"] = ctrl.Ctx.GetCookie("name")
	// don't forget this
	_ = ctrl.Render()
}

others means：

• others[0]: maxAge, means Expires and Max-Age
• others[1]: Path, string, the default value is /
• others[2]: Domain, string
• others[3]: Secure, bool
• others[4]: HttpOnly, bool
• others[5]: SameSite, string

Encryption

Beego provides two methods to assist with cookie encryption, it uses sha256 as the encryption algorithm and Secret as the encryption key:

• GetSecureCookie(Secret, key string) (string, bool)
• SetSecureCookie(Secret, name, value string, others ...interface{})

type MainController struct {
	web.Controller
}

func (ctrl *MainController) PutSecureCookie() {
	// put something into cookie, set Expires time
	ctrl.Ctx.SetSecureCookie("my-secret", "name", "web cookie")

	// web-example/views/hello_world.html
	ctrl.TplName = "hello_world.html"
	ctrl.Data["name"] = "PutCookie"
	_ = ctrl.Render()
}

func (ctrl *MainController) ReadSecureCookie() {
	// web-example/views/hello_world.html
	ctrl.TplName = "hello_world.html"
	ctrl.Data["name"], _ = ctrl.Ctx.GetSecureCookie("my-secret", "name")
	// don't forget this
	_ = ctrl.Render()
}
