cookies使用

1.基础cookies操作

目录结构

主目录basic

    —— main.go    —— main_test.go

代码示例

main.go

package mainimport "github.com/kataras/iris"func newApp() *iris.Application {    app := iris.New()    app.Get("/cookies/{name}/{value}", func(ctx iris.Context) {        name := ctx.Params().Get("name")        value := ctx.Params().Get("value")        ctx.SetCookieKV(name, value) // <-- 设置一个Cookie        // 另外也可以用: ctx.SetCookie(&http.Cookie{...})        // 如果要设置自定义存放路径：        // ctx.SetCookieKV(name, value, iris.CookiePath("/custom/path/cookie/will/be/stored"))        ctx.Request().Cookie(name)        //如果您希望仅对当前请求路径可见：        //（请注意，如果服务器发送空cookie的路径，所有浏览器都兼容，将会使用客户端自定义路径）        // ctx.SetCookieKV(name, value, iris.CookieCleanPath /* or iris.CookiePath("") */)        // 学习更多:        //                              iris.CookieExpires(time.Duration)        //                              iris.CookieHTTPOnly(false)        ctx.Writef("cookie added: %s = %s", name, value)    })    app.Get("/cookies/{name}", func(ctx iris.Context) {        name := ctx.Params().Get("name")        value := ctx.GetCookie(name) // <-- 检索，获取Cookie        //判断命名cookie不存在，再获取值        // cookie, err := ctx.Request().Cookie(name)        // if err != nil {        //  handle error.        // }        ctx.WriteString(value)    })    app.Delete("/cookies/{name}", func(ctx iris.Context) {        name := ctx.Params().Get("name")        ctx.RemoveCookie(name) // <-- 删除Cookie        //如果要设置自定义路径：        // ctx.SetCookieKV(name, value, iris.CookiePath("/custom/path/cookie/will/be/stored"))        ctx.Writef("cookie %s removed", name)    })    return app}func main() {    app := newApp()    // GET:    http://localhost:8080/cookies/my_name/my_value    // GET:    http://localhost:8080/cookies/my_name    // DELETE: http://localhost:8080/cookies/my_name    app.Run(iris.Addr(":8080"))}

2.cookies加密

目录结构

主目录securecookie

    —— main.go    —— main_test.go

代码示例

main.go

package main//开发人员可以使用任何库添加自定义cookie编码器/解码器。//在这个例子中，我们使用gorilla的securecookie包：// $ go get github.com/gorilla/securecookie// $ go run main.goimport (    "github.com/kataras/iris"    "github.com/gorilla/securecookie")var (    // AES仅支持16,24或32字节的密钥大小。    //您需要准确提供该密钥字节大小，或者从您键入的内容中获取密钥。    hashKey  = []byte("the-big-and-secret-fash-key-here")    blockKey = []byte("lot-secret-of-characters-big-too")    sc       = securecookie.New(hashKey, blockKey))func newApp() *iris.Application {    app := iris.New()    app.Get("/cookies/{name}/{value}", func(ctx iris.Context) {        name := ctx.Params().Get("name")        value := ctx.Params().Get("value")        //加密值        ctx.SetCookieKV(name, value, iris.CookieEncode(sc.Encode)) // <--设置一个Cookie        ctx.Writef("cookie added: %s = %s", name, value)    })    app.Get("/cookies/{name}", func(ctx iris.Context) {        name := ctx.Params().Get("name")        //解密值        value := ctx.GetCookie(name, iris.CookieDecode(sc.Decode)) // <--检索Cookie        ctx.WriteString(value)    })    app.Delete("/cookies/{name}", func(ctx iris.Context) {        name := ctx.Params().Get("name")        ctx.RemoveCookie(name) // <-- 删除Cookie        ctx.Writef("cookie %s removed", name)    })    return app}func main() {    app := newApp()    app.Run(iris.Addr(":8080"))}
