我在聊天应用程序中遇到基于 cookie 的令牌身份验证问题。我正在使用带有标准网络库的 go 后端来将令牌添加到响应 cookie。当用户通过密码验证(通过 post 到身份验证服务器上的 /login 路径)时,响应 cookie 应包含用于生成 api 令牌的访问令牌和用于重新生成访问令牌的刷新令牌。
这是一个标记文件,其中包含我的开发环境中应用程序服务的结构。每个服务器都在本地主机上使用 go net/http 在顺序端口上运行(不显示不相关的服务)。
auth_server ( dependencies [] url (scheme "http" domain "localhost" port "8081") listenaddress ":8081" endpoints ( /jwtkeypub ( methods [get] ) /register ( methods [post] ) /logout ( methods [post] ) /login ( methods [post] ) /apitokens ( methods [get] ) /accesstokens ( methods [get] ) ) jwtinfo ( issuername "auth_server" audiencename "auth_server" ) ) message_server ( dependencies [auth_server] url (scheme "http" domain "localhost" port "8083") listenaddress ":8083" endpoints ( /ws ( methods [get] ) ) jwtinfo ( audiencename "message_server" ) ) static ( dependencies [auth_server, message_server] url (scheme "http" domain "localhost" port "8080") listenaddress ":8080" )
这是在登录时设置 cookie 的代码。密码检查后会发生这种情况
// set a new refresh token refreshtoken := s.jwtissuer.stringifyjwt( s.jwtissuer.minttoken(userid, s.jwtissuer.name, refreshtokenttl), ) kit.sethttponlycookie(w, "refreshtoken", refreshtoken, int(refreshtokenttl.seconds())) // set a new access token accesstoken := s.jwtissuer.stringifyjwt( s.jwtissuer.minttoken(userid, s.jwtaudience.name, accesstokenttl), ) kit.sethttponlycookie(w, "accesstoken", accesstoken, int(accesstokenttl.seconds())) }
func sethttponlycookie(w http.responsewriter, name, value string, maxage int) { http.setcookie(w, &http.cookie{ name: name, value: value, httponly: true, maxage: maxage, }) }
以下是当用户请求 api 令牌时我如何访问 cookie。如果返回错误,处理程序将调用 gettokenfromcookie() 函数并以 401 进行响应。这种情况下的错误是“http:命名的cookie不存在”
func gethttpcookie(r *http.request, name string) (*http.cookie, error) { return r.cookie(name) } func gettokenfromcookie(r *http.request, name string) (jwt.jwt, error) { tokencookie, err := gethttpcookie(r, name) if err != nil { // debug log.println(err) return jwt.jwt{}, err } return jwt.fromstring(tokencookie.value) }
来自登录端点的 200 响应后,页面重定向到主应用程序页面。在此页面上,向身份验证服务器发出请求以接收用于连接实时聊天消息服务器的 api 令牌。从auth服务器上的日志输出可以看到,请求中没有收到访问令牌cookie,因此请求返回401代码。
2023/05/19 02:33:57 get [/jwtkeypub] - 200 2023/05/19 02:33:57 get [/jwtkeypub] - 200 2023/05/19 02:34:23 post [/login] - 200 2023/05/19 02:34:23 http: named cookie not present {{ } { } []} http: named cookie not present 2023/05/19 02:34:23 get [/apitokens?aud=msgservice] - 401
我相信问题在于我使用的是 localhost,并且浏览器不会将 cookie 从 locahost:8080 传输到 localhost:8081。我正计划实现某种模拟身份验证,绕过读取开发环境的 cookie 来解决这个问题,但我不确定这是否真的是我的问题的原因。只是想再看一下,看看我是否可以让它工作而不需要这样做。
更新:我已经查看了开发工具中的网络选项卡: 图像显示登录后的响应返回了 cookie,但它们随后不会发送到端口 8081 上的身份验证服务器。在获得登录的 200 响应后,我还查看了 cookie 存储,即使在之后也没有 cookie在响应中接收它们。我正在使用 firefox 的私人模式来访问该网站。请注意,即使我在 go 代码中设置了 maxage,cookie 也不包含 maxage,这似乎是一个问题。
更新:这是登录后的 har 文件。您可以看到响应有 max-age,但之后它不会显示在 cookies 选项卡中。

响应似乎有 cookie,但它们没有被保存。
并且对身份验证服务器的下一个请求没有添加任何 cookie。
tl;dr:
0.0.0.0
和 localhost
之间共享。http://localhost:8080
和 http://localhost:8081
之间共享。http://localhost:8080/
页面发送到 http://localhost:8081/
的请求将被视为跨域请求。fetch
发送的跨域请求应使用 credentials: 'include'
进行初始化,以使浏览器保存 cookie。har显示网页的url为http://localhost:8080/
,但登录端点为http://0.0.0.0:8081/login
。 0.0.0.0
的 cookie 不会与 localhost
共享。
您可以运行下面的演示来观察行为:
运行演示:go run main.go
;
在浏览器中打开http://localhost:8080/
。该网页将执行以下操作:
http://0.0.0.0:8081/login1
发送请求(目的是验证0.0.0.0
的cookie不会与localhost
共享;http://localhost:8081/login2
发送请求(目的是验证会话 cookie 将在 http://localhost:8081/login2
发送请求(目的是验证会话 cookie 将在 http://localhost:8080
和 http://localhost:8081
之间共享;http://localhost:8081/login3
发送请求(目的是验证正常的cookie将在http://localhost:8080
和http://localhost:8081
之间共享;http://localhost:8080/resource
并且服务器将转储请求。表明这个头被发送到服务器:cookie:login2=localhost-session; login3=localhost
。注释: credentials: 'include'
要求将 access-control-allow-origin
标头设置为确切的来源(这意味着 *
将被拒绝),并且 access- control-allow-credentials
标头设置为 true
。
package main import ( "fmt" "log" "net/http" "net/http/httputil" ) func setHeader(w http.ResponseWriter, cookieName, cookieValue string, maxAge int) { w.Header().Set("Access-Control-Allow-Origin", "http://localhost:8080") w.Header().Set("Access-Control-Allow-Credentials", "true") http.SetCookie(w, &http.Cookie{ Name: cookieName, Value: cookieValue, MaxAge: maxAge, HttpOnly: true, }) } func main() { muxWeb := http.NewServeMux() // serve the HTML page. muxWeb.Handle("/", http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { _, err := w.Write([]byte(page)) if err != nil { panic(err) } })) // Dump the request to see what cookies is sent to the server. muxWeb.Handle("/resource", http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { dump, err := httputil.DumpRequest(r, false) if err != nil { panic(err) } _, _ = w.Write(dump) })) web := &http.Server{ Addr: ":8080", Handler: muxWeb, } go func() { log.Fatal(web.ListenAndServe()) }() muxAPI := http.NewServeMux() muxAPI.Handle("/login1", http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { setHeader(w, "login1", "0.0.0.0", 1200) })) muxAPI.Handle("/login2", http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { setHeader(w, "login2", "localhost-session", 0) })) muxAPI.Handle("/login3", http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { setHeader(w, "login3", "localhost", 1200) })) api := &http.Server{ Addr: ":8081", Handler: muxAPI, } go func() { log.Fatal(api.ListenAndServe()) }() fmt.Println("Open http://localhost:8080/ in the browser") select {} } var page string = ` <!DOCTYPE html> <html> <body> <script type="module"> async function login(url) { const response = await fetch(url, { mode: 'cors', credentials: 'include', }); } await login('http://0.0.0.0:8081/login1'); await login('http://localhost:8081/login2'); await login('http://localhost:8081/login3'); window.location = '/resource'; </script> </body> </html> `
