Apache CURL错误SSL：CA证书集，但禁用证书验证

问题：我的开发环境正在创建此错误，我提交的是使用CURL的登录表单 . CURL产生此错误，我认为该错误与为SSL连接生成的证书相关联 .

My dev environment is:

• Mac OS X Capitan 10.11

• Apache 2.4 / PHP 7.0.12

phpinfo() states:

• cURL：启用/ 7.50.3 / SSL：是/协议：dict，file，ftp，ftps，gopher，http，https，imap，imaps，ldap，ldaps，pop3，pop3s，rtsp，scp，sftp，smb，smbs ，smtp，smtps，telnet，tftp / SSL版本：SecureTransport / ZLib版本：1.2.5 / libSSH版本：libssh2 / 1.4.3

• OpenSSL：启用/库版本：OpenSSL 1.0.2h 2016年5月3日/ Headers 版本：OpenSSL 1.0.2h 2016年5月3日/ openssl.cafile :(本地）/usr/local/php5/ssl/certs/cacert.pem和（主人）/usr/local/php5/ssl/certs/cacert.pem

为了创建SSL设置，我在这篇文章之后发布了一个消除浏览器请求的tee，并允许我提取涉及Twitter等需要SSL连接的项目的请求，即使在开发环境中也是如此 .

但是，PHP 5.6 . 我最初用于开发这个特定的项目，并且最近我升级到7，现在已经导致了这个错误 .

在测试证书方面，终端显示错误如下：

echo | openssl s_client -connect localhost:443

上面的命令产生了：

CONNECTED(00000003)

DONE

对于产生此错误的登录页面，我使用的是Auth0.com，我拒绝更改CURL请求verifypeer = false以抑制此错误，因为错误清楚地表明泄漏 . 作为开发人员，我们希望尽可能地复制我们的开发环境，以确保在转向 生产环境 时不会遗漏任何东西 .

谢谢，希望我已经涵盖了这里所需的一切 . 我不使用外部软件包，如MAMP或XAMPP等，只是将PHP7安装作为Capitan附带的现有PHP 5.5的升级 .

干杯!
