Set and get a cookie

Secure cookies, encoding and decoding, sessions (and sessions scaling), flash messages and more can be found at the _examples/cookies and _examples/sessions directories respectfully.

import "github.com/kataras/iris/v12"

func main() {
    app := iris.Default()

    app.Get("/cookie", func(ctx iris.Context) {
        value := ctx.GetCookie("my_cookie")

        if value == "" {
            value = "NotSet"
            ctx.SetCookieKV("my_cookie", value)
            // Alternatively: ctx.SetCookie(&http.Cookie{...})
            ctx.SetCookie("", "test", 3600, "/", "localhost", false, true)
        }

        ctx.Writef("Cookie value: %s \n", cookie)
    })

    app.Listen(":8080")
}

If you want to set custom the path:

ctx.SetCookieKV(name, value, iris.CookiePath("/custom/path/cookie/will/be/stored"))

If you want to be visible only to current request path:

ctx.SetCookieKV(name, value, iris.CookieCleanPath /* or iris.CookiePath("") */)

More:

• iris.CookieAllowReclaim
• iris.CookieAllowSubdomains
• iris.CookieSecure
• iris.CookieHTTPOnly
• iris.CookieSameSite
• iris.CookiePath
• iris.CookieCleanPath
• iris.CookieExpires
• iris.CookieEncoding

You can add cookie options for the whole request in a middleware too:

func setCookieOptions(ctx iris.Context) {
    ctx.AddCookieOptions(iris.CookieHTTPOnly(true), iris.CookieExpires(1*time.Hour))
    ctx.Next()
}
