概述

示例
概述
Cookiejar包实现了符合内存RFC 6265的http.CookieJar。
索引
type Jar
func New(o *Options) (*Jar, error)
func (j *Jar) Cookies(u *url.URL) (cookies []*http.Cookie)
func (j *Jar) SetCookies(u *url.URL, cookies []*http.Cookie)
type Options
type PublicSuffixList
文件包
jar.go punycode.go
type Jar
Jar从net/http包实现http.CookieJar接口。
type Jar struct { // contains filtered or unexported fields}func New
func New(o *Options) (*Jar, error)
New返回一个新的cookie jar。无*选项相当于零选项。
示例
代码：
// Start a server to give us cookies.ts := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { if cookie, err := r.Cookie("Flavor"); err != nil {
http.SetCookie(w, &http.Cookie{Name: "Flavor", Value: "Chocolate Chip"}) } else {
cookie.Value = "Oatmeal Raisin"
http.SetCookie(w, cookie) }}))defer ts.Close()u, err := url.Parse(ts.URL)if err != nil {
log.Fatal(err)}// All users of cookiejar should import "golang.org/x/net/publicsuffix"jar, err := cookiejar.New(&cookiejar.Options{PublicSuffixList: publicsuffix.List})if err != nil {
log.Fatal(err)}client := &http.Client{
Jar: jar,}if _, err = client.Get(u.String()); err != nil {
log.Fatal(err)}fmt.Println("After 1st request:")for _, cookie := range jar.Cookies(u) {
fmt.Printf(" %s: %s\n", cookie.Name, cookie.Value)}if _, err = client.Get(u.String()); err != nil {
log.Fatal(err)}fmt.Println("After 2nd request:")for _, cookie := range jar.Cookies(u) {
fmt.Printf(" %s: %s\n", cookie.Name, cookie.Value)}输出：
After 1st request: Flavor: Chocolate Chip After 2nd request: Flavor: Oatmeal Raisin
func (*Jar) Cookies
func (j *Jar) Cookies(u *url.URL) (cookies []*http.Cookie)
Cookies实现http.CookieJar界面的Cookies方法。
如果URL的方案不是HTTP或HTTPS，它将返回空片。
func (*Jar) SetCookies
func (j *Jar) SetCookies(u *url.URL, cookies []*http.Cookie)
SetCookies实现了http.CookieJar接口的SetCookies方法。
如果URL的方案不是HTTP或HTTPS，它什么也不做。
type Options
选项是创建新Jar的选项。
type Options struct { // PublicSuffixList is the public suffix list that determines whether // an HTTP server can set a cookie for a domain. // // A nil value is valid and may be useful for testing but it is not // secure: it means that the HTTP server for foo.co.uk can set a cookie // for bar.co.uk.
PublicSuffixList PublicSuffixList}type PublicSuffixList
PublicSuffixList提供域的公共后缀。例如：
- the public suffix of "example.com" is "com",- the public suffix of "foo1.foo2.foo3.co.uk" is "co.uk", and- the public suffix of "bar.pvt.k12.ma.us" is "pvt.k12.ma.us".
PublicSuffixList的实现必须安全，以供多个goroutine并发使用。
总是返回“”的实现是有效的，对于测试可能有用，但它不安全：这意味着foo.com的HTTP服务器可以为bar.com设置cookie。
公共后缀列表实现位于golang.org/x/net/publicsuffix包中。
type PublicSuffixList interface { // PublicSuffix returns the public suffix of domain. // // TODO: specify which of the caller and callee is responsible for IP // addresses, for leading and trailing dots, for case sensitivity, and // for IDN/Punycode. PublicSuffix(domain string) string // String returns a description of the source of this public suffix // list. The description will typically contain something like a time // stamp or version number. String() string}
