Question

所以我无法找到进行 SSL 检查的正确方法，我没有使用证书，只需要检查 HTTPS 网站 url（例如 google.com/）一次尝试多种组合，没有成功。也许有人有类似的配置，

后端使用 - > 检查 sni google.com sni ssl_fc_sni

<块引用>

    returns - reason: Layer7 wrong status, code: 301, info: "Moved Permanently"

检查端口 80 check-ssl -

<块引用>

原因：Layer6 响应无效，信息：“SSL 握手失败”

所有其他人都超时了。这是完整的配置文件-

Ps 找到了一个网站，它解释了我正在尝试做什么（https://hodari.be/posts/2020_09_04_configure_sni_for_haproxy_backends/），但这也不起作用，我的haproxy 版本是 2.2.3

P.s.s 我真的想检查 www.google.com ，只是为了清楚。谢谢！

这真的不是错误。如果您对 https://google.com 执行 curl 操作，它会执行到 https://www.google.com/ 的 301 重定向。为简洁起见，我在下面剪掉了一些协议细节，但你懂的。

要么将您的期望更改为 301，要么使用 www.google.com。

因此，如果您想避免 301，请在您的配置中使用 www.google.com 值，如下所示：

http-check send hdr host www.google.com meth GET uri /
