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.

我也遇到过这个问题。我读了这篇文章，大部分答案都很有信息量，但对我来说太复杂了。我在社交话题上没有经验，所以这个答案适合像我这样的人。

在我的例子中，发生这个错误是因为我没有在应用程序中使用的证书旁边包含中间证书和根证书。

以下是我从SSL证书供应商那里得到的信息:

- abc.crt
- abc.pem
- abc-bunde.crt

在abc。CRT文件，只有一个证书:

-----BEGIN CERTIFICATE-----
/*certificate content here*/
-----END CERTIFICATE-----

如果我以这种格式提供它，浏览器将不会显示任何错误(Firefox)，但我会得到curl:(60) SSL证书:无法获得本地颁发者证书错误时，我做curl请求。

要修复此错误，请检查abc-bunde。crt文件。你很可能会看到这样的东西:

这些是您的中级证书和根证书。发生错误是因为您提供给应用程序的SSL证书中缺少它们。

要修复此错误，请以以下格式合并这两个文件的内容:

请注意，证书之间、文件的末尾或开头没有空格。一旦您向应用程序提供了这个组合证书，您的问题就会得到解决。

其他回答

这是ssh证书存储问题。请先从目标CA网站下载有效的证书pem文件，再构建软链接文件指示ssl信任证书。

openssl x509 -hash -noout -in DigiCert_Global_Root_G3.pem

您将得到dd8e9d41

使用散列号构建solf链接，并以.0(点- 0)作为文件后缀

DD8E9D41.0

然后再试一次。

您必须将服务器证书从cert.pem更改为fullchain.pem 我有同样的问题与Perl HTTPS守护进程: 我已经改变了: SSL_cert_file => '/etc/letsencrypt/live/mydomain/cert.pem' : SSL_cert_file => '/etc/letsencrypt/live/mydomain/fullchain.pem'

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。

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/)。

没有一个答案提到，可能是连接到内部vpn的角色，我以前遇到过这个问题，并要求在专用网络上
