当我尝试使用curl(或libcurl)连接到任何服务器(例如google.com)时,我收到错误消息:
curl:(35)错误:1408F10B:SSL例程:ssl3_get_record:版本号错误
详细输出:
$ curl www.google.com --verbose
* Rebuilt URL to: www.google.com/

由于某种原因curl似乎使用TLSv1.3,即使我强制它使用TLSv1.2命令--tlsv1.2(它仍将打印TLSv1.3(OUT),..."我使用的是最新版本Curl和OpenSSL:
$ curl -V …尽管Google上有很多结果,但似乎没有人给出答案.我有一个Debian框,我这样做:
# curl https://localhost/api/v1/status --verbose
* About to connect() to localhost port 443 (#0)
* Trying ::1...
* connected
* Connected to localhost (::1) port 443 (#0)

我无法通过未知协议的事情.我试过-ssl -sslv3,但他们让我无处可去.实际上,-sslv3让我略有不同的结果:
s# curl https://localhost/api/v1/status --verbose -sslv3
* About to connect() to localhost port 443 (#0)
