英文:

ory kratos csrf cookie not being sent behind nginx ssl

问题

我正在使用Docker中的Go和ory kratos，在我的本地机器上的localhost上一切正常工作。

认证工作正常，所有的cookie都被发送和设置，我可以从SPA调用我的后端并进行身份验证。

问题是，在nginx和ssl后面的生产服务器上，显然只有一个cookie没有从我的js客户端发送（只有ory_kratos_session被发送，而没有xxx_csrf_token cookie），并且它在下面的函数中由于缺少cookie而失败。

它使用官方的go sdk：kratos-client-go

Go AuthRequired中间件

func ExtractKratosCookiesFromRequest(r *http.Request) (csrf, session *http.Cookie, cookieHeader string) {
	cookieHeader = r.Header.Get("Cookie")

	cookies := r.Cookies()
	for _, c := range cookies {
		if c != nil {
			if ok := strings.HasSuffix(c.Name, "csrf_token"); ok {
				csrf = c
			}
		}
	}

	sessionCookie, _ := r.Cookie("ory_kratos_session")
	if sessionCookie != nil {
		session = sessionCookie
	}

	return
}

func AuthRequired(w http.ResponseWriter, r *http.Request) error {
	csrfCookie, sessionCookie, cookieHeader := ExtractKratosCookiesFromRequest(r)
	if (csrfCookie == nil || sessionCookie == nil) || (csrfCookie.Value == "" || sessionCookie.Value == "") {
		return errors.New("Cookie missing")
	}

	req := kratos.PublicApi.Whoami(r.Context()).Cookie(cookieHeader)
	kratosSession, _, err := req.Execute()
	if err != nil {
		return errors.New("Whoami error")
	}
	
	return nil
}

我的js http客户端有选项：credentials: 'include'。

在开发工具面板中，我只看到一个cookie（ory_kratos_session）在注册/登录后。

所以问题出在请求只发送了ory_kratos_session而没有发送xxx_csrf_token cookie（在kratos的--dev模式下在localhost上工作，并且在开发工具面板中可见）。

我不明白为什么它在生产服务器上不起作用，这一定与ssl有关。

这是我正在使用的http客户端（ky.js，但它与fetch相同）：

const options = {
  prefixUrl: 'https://example.com/api/v1',
  headers: {
    'Content-Type': 'application/json; charset=UTF-8',
    Accept: 'application/json',
  },
  timeout: 5000,
  mode: 'cors',
  credentials: 'include',
};

export const apiClient = ky.create(options);

我只是调用了我的受保护的后端路由，该路由受到AuthRequired中间件的保护，没有什么特别的：

function createTodo(data) {
  return apiClient.post(`todos`, { json: data }).json();
}

ory/kratos-client（js sdk）配置如下：

const conf = new Configuration({
  basePath: 'https://example.com/kratos',
  // 这些是axios选项（kratos js sdk在内部使用axios）
  baseOptions: { 
    withCredentials: true,
    timeout: 5000,
  },
});

export const kratos = new PublicApi(conf);

奇怪的是，在Firefox中，我在开发工具面板中看到了2个cookie，但在Chrome中没有。

这是csrf的一个：

这是会话cookie：

我以为这与容器中的时区有关，我也在所有容器中挂载了这个卷：-v /etc/localtime:/etc/localtime:ro

PS

问题是，每当我docker-compose restart kratos，事情就会出错，显然旧的csrf_token被使用。
这应该如何使用，我不能告诉我的用户，嘿，去你的浏览器删除所有缓存和cookie。
当我清除所有东西时，它可以工作，但一旦我重启了nginx，它就不再工作了（docker-compose restart后也是如此）...非常奇怪。

这个人在这里遇到了同样的问题：csrf问题重启后

英文:

I am using Go with ory kratos in docker and everything works fine on my machine on localhost.
Auth works, all cookies are send and set and i can call my backend from SPA and be authenticated.

The problem is that on live server behind nginx and ssl, apparently one cookie is not being sent from my js client (only ory_kratos_session is being sent and not xxx_csrf_token cookie) and it fails in function bellow with cookie missing error.

it uses official go sdk: kratos-client-go

Go AuthRequired middleware

func ExtractKratosCookiesFromRequest(r *http.Request) (csrf, session *http.Cookie, cookieHeader string) {
	cookieHeader = r.Header.Get(&quot;Cookie&quot;)

	cookies := r.Cookies()
	for _, c := range cookies {
		if c != nil {
			if ok := strings.HasSuffix(c.Name, string(&quot;csrf_token&quot;)); ok {
				csrf = c
			}
		}
	}

	sessionCookie, _ := r.Cookie(&quot;ory_kratos_session&quot;)
	if sessionCookie != nil {
		session = sessionCookie
	}

	return
}

func AuthRequired(w http.ResponseWriter, r *http.Request) error {
	csrfCookie, sessionCookie, cookieHeader := ExtractKratosCookiesFromRequest(r)
	if (csrfCookie == nil || sessionCookie == nil) || (csrfCookie.Value == &quot;&quot; || sessionCookie.Value == &quot;&quot;) {
		return errors.New(&quot;Cookie missing&quot;)
	}

	req := kratos.PublicApi.Whoami(r.Context()).Cookie(cookieHeader)
	kratosSession, _, err := req.Execute()
	if err != nil {
		return errors.New(&quot;Whoami error&quot;)
	}
	
	return nil
}

My js http client has option: credentials: 'include'.

In devtools panel i see only 1 cookie (ory_kratos_session) after register/login.

So what is failing is that request is only sending ory_kratos_session and not xxx_csrf_token cookie (which works on localhost in kratos --dev mode, and cookie is vidisble in devtools panel)

}

I don't understand why it is not working on live server, it has to be something with ssl

this is my http client that i am using (ky.js but it doesn't matter its the same as fetch)

const options = {
  prefixUrl: &#39;https://example.com/api/v1&#39;,
  headers: {
    &#39;Content-Type&#39;: &#39;application/json; charset=UTF-8&#39;,
    Accept: &#39;application/json&#39;,
  },
  timeout: 5000,
  mode: &#39;cors&#39;,
  credentials: &#39;include&#39;,
};

export const apiClient = ky.create(options);

i'm just calling my backend protected route that is protected with AuthRequired middleware, nothing special:

function createTodo(data) {
  return apiClient.post(`todos`, { json: data }).json();
}

ory/kratos-client (js sdk) is configured like this:

const conf = new Configuration({
  basePath: &#39;https://example.com/kratos&#39;,
  // these are axios options (kratos js sdk uses axios under the hood)
  baseOptions: { 
    withCredentials: true,
    timeout: 5000,
  },
});

export const kratos = new PublicApi(conf);

It's strange that in firefox i see 2 cookies in devtools panel but not in chrome.

this is csrf one:

aHR0cHM6Ly9hbmltb25kLnh5ei9rcmF0b3Mv_csrf_token:&quot;Kx+PXWeoxsDNxQFGZBgvlTJScg9VIYEB+6cTrC0zsA0=&quot;

I thought it was something related to the timezones in the containers, i also mounted this volume in all of them: -v /etc/localtime:/etc/localtime:ro

PS

The problem is that whenever i docker-compose restart kratos, things get broken, somehow apparently old csrf_token is being used.
How is this supposed to be used, i can't just tell my users hey go to your browser and delete all cache and cookies.
when i prune everything it works, but once i restarted nginx and it didn't work after that (same is after docker-compose restart)... very strange

this guy had the same problem here: csrf problem after restart

我相信你的kratos配置是不正确的。
属性serve.public.base_url应该是请求来源的URL，例如https://example.com/kratos/，而不是你的本地主机http://127.0.0.1:4433。

另外，我建议你的管理端点不应该对外公开，你的后端服务应该在内部网络上请求管理URL（例如在Docker内部或本地主机上）。你的serve.admin.base_url应该是http://127.0.0.1:4434，并从nginx中移除。

根据我看来，nginx配置是正确的。我相信你只需要以下内容使其正常工作：

location /kratos/ {
    proxy_set_header Host $host;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_pass http://127.0.0.1:4433;
}

英文:

I believe your kratos configurations are incorrect.
The property serve.public.base_url should be the url the request is originating from e.g. https://example.com/kratos/ instead of your localhost http://127.0.0.1:4433.

Also just a word of recommendation, your admin endpoint should never be exposed to the public, your backend services should request the admin url on an internal network (e.g. inside docker or on localhost). Your serve.admin.base_url should be http://127.0.0.1:4434 instead and removed from nginx.

The nginx configurations seem correct to me. I believe you only require this for it to work:

location /kratos/ {
    proxy_set_header Host $host;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection &quot;upgrade&quot;;
    proxy_pass http://127.0.0.1:4433;
}

我确实成功解决了这个问题，在生产环境中不使用--dev标志也能正常工作，并且即使在重新启动服务和更改所有内容之后也不会出现问题。

也许是我在React表单中使用了defaultValue来设置csrf令牌输入框的值。

现在，无论window.location的URL变化还是csrf_token的变化，它都应该使用最新的csrf_token值。

const [csrf, setCsrf] = React.useState('');

useEffect(() => {
  if (flowResponse !== null) {
    const csrfVal = flowResponse?.ui?.nodes?.find?.(n => n.attributes.name === 'csrf_token')?.attributes.value;
    setCsrf(csrfVal);
  }
}, [flowResponse, csrf]);

<input type='hidden' name='csrf_token' value={csrf} readOnly required />

最糟糕的是，可能是尾部斜杠或其他一些微小的问题，我不确定具体是什么导致了这个问题。

这里是所有对我有效的配置：

之前我尝试过将kratos的URL设置为http://127.0.0.1:4433或http://kratos:4433，但它不起作用（尽管我在这三者之间切换哈哈）。

I did manage to solve this, it works fine without --dev flag in production and doesn't get screwed up even after restarting the services and changing everything.

Maybe it was even my react form where i used defaultValue for the csrf token input

Now whenever window.location url changes or whenever csrf_token changes, it should use the latest value for the csrf_token

const [csrf, setCsrf] = React.useState(&#39;&#39;);

useEffect(() =&gt; {
  if (flowResponse !== null) {
    const csrfVal = flowResponse?.ui?.nodes?.find?.(n =&gt; n.attributes.name === &#39;csrf_token&#39;)?.attributes.value;
    setCsrf(csrfVal);
  }
}, [flowResponse, csrf]);

&lt;input type=&#39;hidden&#39; name=&#39;csrf_token&#39; value={csrf} readOnly required /&gt;

the worst thing is that it could have also been a trailing slash or something so small that i am not sure exactly what caused it.

Here all post all the configuration that worked for me:

could have been that i tried before with this kratos url being http://127.0.0.1:4433 or http://kratos:4433 and it didn't work (even though i was switching between these 3 haha)
