curl：（35）错误：1407742E:SSL例程：SSL23\u GET\u SERVER\u HELLO:tlsv1警报协议版本

我试图使用

curl

，但遇到以下问题：

# curl -v --cacert ./ca.crt --key ./private/X.key --cert ./issued/X.crt https://X.X.X

请注意。

我还尝试从另一个环境运行相同的curl命令（相同的结果）：

但是，从另一个环境运行可以解决任何问题：

$ curl --version

$ cat /etc/debian_version

所有环境都在使用适用于操作系统的最新（最新）版本的curl/openssl包

---

我认为这与较旧版本的curl有关，并且/或者openssl不支持最新的tlsv1.3，因为工作环境有以下特点：

$ curl --help | grep -- --tlsv1.3
     --tlsv1.3       Use TLSv1.3 or greater
$ 

---

在我的例子中，它是来自PHP5.2.17的curl的旧版本：curl Information=>libcurl/7.21.0openssl/0.9.8qzlib/1.2。3@b3wiitls1.3仅在openssl1.1.1中引入

$ curl --help | grep -- --tlsv1.3
     --tlsv1.3       Use TLSv1.3 or greater
