node.js - 使用 cookie 的 iFraming Kibana 仪表板时出现 TOO_MANY_REDIRECTS 错误

coder 2023-05-29 原文

根据 this thread 中的信息，我正在尝试将受密码保护的 Kibana 仪表板嵌入到我的 Node 驱动的 Express 应用程序的 iFrame 中。 . Kibana 使用 X-Pack 进行保护，需要用户登录才能查看其可视化数据。

目前这需要用户登录两次，一次登录应用程序，一次登录到 Kibana 仪表板，这不是目标。

根据该线程中的信息，我实现了一些代码，向 https://elk-stack.my.domain:5601/api/security/v1/login 发出飞行前 POST 请求获取 cookie ?

这个客户端请求...

function preFlightKibanaAuth () {
    ...
    $.ajax({
      type: 'POST',
      url: '/kibana-auth',
      datatype: 'json',
      success: function (response) {
        if (response && response.authenticated) {
          $('iframe#kibana-dashboard').prop('src', 'https://elk-stack.my.domain:5601/s/spacename/app/kibana#/dashboards?_g=()')
        }
      },
      error: function (err) {
        console.log(err)
      }
    })
  }

被路由到这个路由...

router
  .route('/kibana-auth')
  .post((req, res, next) => {
    ... 
    if (authorised) {
      ...
      authenticateKibana(req)
          .then(cookie => {
            if (cookie && cookie.name && cookie.value) {
              res.set('Set-Cookie', `${cookie.name}=${cookie.value}; Domain=my.domain; Path=/; Secure; HttpOnly`)
              res.send({ 'authenticated': true })
            } else {
              res.send({ 'authenticated': false })
            }
          })
          .catch((err) => {
            logger.error(err)
            res.send({ 'authenticated': false })
          })
    }
    ...
  })

这使得它成为这个函数的方式，cookie实际上是在其中获取和解析的......

authenticateKibana () {
    return new Promise((resolve, reject) => {
      ...
      request({
        method: 'POST',
        uri: `https://elk-stack.my.domain:5601/api/security/v1/login`,
        headers: {
          'kibana-version': '6.5.4',
          'kibana-xsrf': 'xsrftoken',    
        },
        type: 'JSON',
        form: {
          password: 'validPassword',
          username: 'validUsername'
        }
      }, function (error, res, body) {
        if (!error) {
          let cookies = cookieParser.parse(res)
          cookies.forEach(function (cookie) {
            if (cookie.name.startsWith('kibana')) {
              // Got Kibana Cookie
              return resolve(cookie)
            }
          })
        } 
        ... 
      })
    })
  }

这很好用，我可以成功通过 Kibana 进行身份验证，获取 cookie 并在客户端浏览器中设置(见下面的截图)。

我看到的问题是 iFrame 的 src 在 preFlightKibanaAuth() 请求的成功回调中更新。我可以简单地看到经过身份验证的 Kibana 仪表板加载(因此 cookie 是 允许客户端查看其经过身份验证的仪表板)，但是，然后我看到对 /login?next=% 的多个 GET 请求2Fs%2Fspacename%2Fapp%2Fkibana 导致 TOO_MANY_REDIRECTS 错误。

我在 GitHub issues page 中找到了以下评论，我认为这可能是我在某种程度上遇到的问题，因为我在日志中看到了这个(见底部):"message":"Found 2 auth session when we were only expecting 1."。我就是想不通!

Usually what causes this is having multiple cookies for the same "domain" and "name", but with different values for "path". If you open the developer tools in Chrome, then click on the Application tab, then expand the Cookies section, and click on the domain, do you have multiple cookies with the name "sid"? If so, you can fix this issue by clearing all of them.

我将 cookie 名称从“sid”更改为“kibana”，但其中两个在“应用程序”选项卡中不可见，只是我在调用 /kibana-auth 后设置的一个。

iFrame 然后加载到 https://elk-stack.my.domain:5601/s/spacename/app/kibana#/dashboards?_g=() 并出现问题。清除我的 cookie 只会导致获取并设置另一个(如果我们还没有)，这是必需的，所以这并没有解决问题。

当我将 Set-Cookie header 发送回客户端时，我将 Domain 设置为主域:my.domain ，以 .my.domain 结尾。 Kibana 实例位于子域上:elk-stack.my.domain，如果我登录到 Kibana 前端，我可以看到 cookie 的 Domain it 返回设置为 elk-stack.my.domain。不过我不确定这是否重要。

任何人都可以对此有所了解或指出方向吗？

提前致谢

这里是在发出请求时来自 /var/log/kibana/kibana.stdout 的日志信息的一瞥。里面还有一些垃圾，但你仍然可以看到发生了什么。

Kibana 版本:6.5.4

Elasticsearch :6.5.4

最佳答案

起初，我以为这一切都是 Cookie 属性不匹配，唉，事实并非如此!

从 Elastic 团队收到了一些信息...

The cookie which Kibana replies with generally sets the httpOnly flag, and the secure flag (when hosted over https), in addition to the domain. If any of the settings differ for the cookie which you're trying to force Kibana to use, you'll see 2 cookies being submitted and behaviour similar to what you're seeing.

我以为我设置了不同属性的 cookie，但没有……最终使用插件来实现这一点:https://readonlyrest.com/
