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.

在亚马逊Linux (CentOS / Red Hat等)上,我做了以下工作来解决这个问题。首先复制cacert。Pem从http://curl.haxx.se/ca/cacert.pem下载,放在/etc/pki/ca-trust/source/anchors/目录下。执行update-ca-trust命令。
下面是来自https://serverfault.com/questions/394815/how-to-update-curl-ca-bundle-on-redhat的一句话
Curl https://curl.se/ca/cacert.pem -o /etc/pki/ca-trust/source/anchors/curl-cacert-updated。Pem && update-ca-trust
然而,由于curl被破坏,我实际上使用这个命令来下载cacert。pem文件。
Wget——no-check-certificate http://curl.haxx.se/ca/cacert.pem
另外,如果你在使用php时遇到了问题,你可能需要重新启动你的web服务器服务httpd restart for apache或service nginx restart for nginx。

输入这两个代码以禁用SSL证书颁发。这对我很有效 经过大量研究,我发现了这个。
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
我在Wordpress安装上试图通过ElasticPress和AWS ACM PCA管理的自签名根CA与内部ElasticSearch服务通信,已经为这个问题困扰了几天。
在我的特殊情况下,我从默认的cURL传输以及预期的正文中收到了200 OK响应,但Wordpress返回了一个WP_Error对象,ElasticPress由于这个证书问题而获得,但从未记录。
说到Wordpress,有两件事值得注意:
The default cURL Transport for all wp_remote_* calls will look to a CA Bundle located in wp-includes/certificates/ca-bundle.crt. This bundle serves largely the same purpose as what's found under https://curl.haxx.se/docs/caextract.html, and will cover most use-cases that don't typically involve more exotic setups. Action/Filter order matters in Wordpress, and in ElasticPress' case, many of its own internal functions leverage these remote calls. The problem is, these remote calls were being executed during the plugins_loaded lifecycle, which is too early for Theme logic to be able to override. If you're using any plugins that make external calls out to other services and you need to be able to modify the requests, you should take careful note as to WHEN these plugins are performing these requests.
这意味着,即使在主题中定义了正确的服务器设置、钩子、回调和逻辑,你仍然可能以一个坏的设置结束,因为底层插件调用在主题加载之前执行得很好,并且永远无法告诉Wordpress关于新证书的信息。
在Wordpress应用程序中,我知道只有两种方法可以在不更新核心或第三方代码逻辑的情况下规避这个问题:
(推荐)添加一个“必须使用”插件到您的安装,调整您需要的设置。MU插件是Wordpress生命周期中最早加载的,可以让你在不直接改变它们的情况下覆盖你的插件和核心。在我的例子中,我用下面的逻辑建立了一个简单的MU插件:
// ep_pre_request_args is an ElasticPress-specific call that we need to adjust for all outbound HTTP requests
add_filter('ep_pre_request_args', function($args){
if($_ENV['ELASTICSEARCH_SSL_PATH'] ?? false) {
$args['sslcertificates'] = $_ENV['ELASTICSEARCH_SSL_PATH'];
}
return $args;
});
(不推荐)如果你实在没有其他选择,你也可以将根CA附加到wp-includes/certificates/ CA -bundle.crt。这似乎会“纠正”潜在的问题,你将得到正确的SSL证书验证,但这种方法将失败每次更新Wordpress,除非你添加额外的自动化。
我添加这个答案是因为在我甚至懒得深入研究插件源代码之前,我已经认为我在我的设置中做了一些错误或不稳定的事情。希望这可以为正在做类似事情的人节省一些时间。
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。
由于conda环境,一些系统可能存在此问题。如果你安装了conda,那么禁用它可以解决你的问题。在我的情况下,当我停用conda时,这个curl-SSL错误得到了解决。在ubuntu或MacOS上试试这个命令
conda deactivate
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/)。
