如何修复 Gentoo 上的curl sslv3警报握手失败？

我正在尝试使用 cURL 打开一个网站，如下所示：

$ curl -vH "Accept: application/json" https://www.rocketleaguereplays.com/api/replays/-1/

输出是：

*   Trying 104.24.114.83...
* Connected to www.rocketleaguereplays.com (104.24.114.83) port 443 (#0)
* ALPN, offering h2
* ALPN, offering http/1.1
* Cipher selection: ALL:!EXPORT:!EXPORT40:!EXPORT56:!aNULL:!LOW:!RC4:@STRENGTH
* successfully set certificate verify locations:
*   CAfile: /etc/ssl/certs/ca-certificates.crt
  CApath: /etc/ssl/certs
* TLSv1.2 (OUT), TLS header, Certificate Status (22):
* TLSv1.2 (OUT), TLS handshake, Client hello (1):
* TLSv1.2 (IN), TLS header, Unknown (21):
* TLSv1.2 (IN), TLS alert, Server hello (2):
* error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure
* Closing connection 0
* TLSv1.2 (OUT), TLS alert, Client hello (1):
curl: (35) error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure

我安装了 Linux 内核 4.4.0 和最新的 cURL 版本：

$ curl -V
curl 7.47.1 (x86_64-pc-linux-gnu) libcurl/7.47.1 OpenSSL/1.0.2f zlib/1.2.8 c-ares/1.10.0 nghttp2/1.6.0
Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp smtp smtps telnet tftp
Features: AsynchDNS IPv6 Largefile NTLM SSL libz TLS-SRP HTTP2 UnixSockets

我怎样才能解决这个问题？在 Ubuntu 上，它可以与 cURL 和相同的 URL 配合使用。

基本上，https://www.rocketleaguereplays.com使用过时的加密 (SSL3)，您可以使用 -k (--insecure) 开关强制curl 连接到像这样的不安全站点。

尝试这个： curl -kvH "Accept: application/json" https://www.rocketleaguereplays.com/api/replays/-1/

您也可以尝试使用-3aka--sslv3开关，但是，如果在构建时不支持 SSL3，那么您需要编译自己的curl 版本，以启用 SSL3。

编辑：操作人员发现了问题。

我对错误消息感到困惑。

这是gentoo 中的一个错误：

https://bugs.gentoo.org/show_bug.cgi?id=531540

基本上，当您使用bindist标志构建openssl时，椭圆曲线加密被禁用。该网站需要椭圆曲线加密。

当我运行这个时，我得到以下信息：

$ curl -vH "Accept: application/json" https://www.rocketleaguereplays.com/api/replays/-1/ * STATE: INIT => CONNECT handle 0x6000572d0; line 1090 (connection #-5000) * Added connection 0.

所以我的卷曲在这个网站上使用了椭圆曲线。
