curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

当前回答

它失败了，因为cURL无法验证服务器提供的证书。

有两个选项可以让它工作:

使用带-k选项的cURL，允许cURL建立不安全的连接，即cURL不验证证书。将根CA(签署服务器证书的CA)添加到/etc/ssl/certs/ca-certificates.crt

您应该使用选项2，因为它是确保您连接到安全FTP服务器的选项。

关于“SSL证书问题:无法获得本地颁发者证书”错误。需要注意的是，这适用于发送CURL请求的系统，而不是接收请求的服务器。

Download the latest cacert.pem from https://curl.se/ca/cacert.pem Add the '--cacert /path/to/cacert.pem' option to the curl command to tell curl where the local Certificate Authority file is. (or) Create or add to a '.curlrc' file the line: cacert = /path/to/cacert.pem See 'man curl', the section about the '-K, --config <file>' section for information about where curl looks for this file. (or if using php) Add the following line to php.ini: (if this is shared hosting and you don't have access to php.ini then you could add this to .user.ini in public_html).

卷毛。cainfo = " - path / to / downloaded cacert pem。”

请确保将路径用双引号括起来!!

默认情况下，FastCGI进程将每300秒解析一次新文件(如果需要，您可以通过添加几个文件来改变频率https://ss88.uk/blog/fast-cgi-and-user-ini-files-the-new-htaccess/)。

到目前为止，我看到这个问题在公司网络中发生，有两个原因，其中一个或两个都可能发生在你的情况中:

由于网络代理的工作方式，它们有自己的SSL证书，从而改变了curl看到的证书。许多或大多数企业网络强制您使用这些代理。在客户端电脑上运行的一些防病毒程序也类似于HTTPS代理，这样它们就可以扫描你的网络流量。您的防病毒程序可能有禁用此功能的选项(假设您的管理员允许)。

作为旁注，上面的第2条可能会让您对被扫描的本应安全的TLS通信感到不安。这就是你的公司世界。
