ssl - 在常见Lisp错误中访问https页面

现在，当我在Common Lisp中尝试使用dexador连接到https站点时，出现此错误：

   SSL verify error: 20 X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY
       [Condition of type CL+SSL:SSL-ERROR-VERIFY]

我该怎么办？

最佳答案

我也遇到这个问题，我没有一个好的解决方案，但它可以工作。看来这是一个问题：

CL-USER> (dex:get "https://www.google.com")
; Evaluation aborted on #<CL+SSL:SSL-ERROR-VERIFY {1006991FA3}>.

此问题与here相关，似乎与CAcerts文件有关。没有正确的CA机构和cl + ssl：

  它可能与CLvSSL中默认禁用的SSLv3有关，因此
  Dexador尝试与TLS 1.2连接。

  Dexador的SSL验证是一个很新的技术，并且还不成熟。它
  最好在Dexador中轻松指定验证设置，
  但是，使用cl + ssl：make-context允许SSLv3是唯一的选择
  我想现在。

因此，目前您有两种选择：

1）使其不安全

CL-USER> (dex:get "https://www.google.com" :insecure t)
"<!doctype html><html itemscope=\"\" itemtype=\"http://schema.org

....
同行：216.58.211.227:443“ {1004DD8003} >>

通常在/etc/ssl/cert.pem中使用ca文件的路径

CL-USER> (dex:get "https://www.google.com" :ca-path "/etc/ssl/oldcert.pem")
