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

我本想评论Yuvik的回答,但我缺乏足够的声誉点。

当您将.crt文件导入到/usr/share/local/ca-certificates时,需要使用正确的格式。其中一些已经在前面提到过,但是还没有人提到只需要一个新的行字符,也没有人收集过清单,所以我想在这里提供一个清单。

The certificate needs to end in .crt. From Ubuntu's man page: Certificates must have a .crt extension in order to be included by update-ca-certificates Certificate files in /usr/local/share/ca-certificates can only contain one certificate Certificate files must end in a newline. update-ca-certificates will appear to work if each row contains, for example, a carriage return + a newline (as is standard in Windows), but once the certificate is appended to /etc/ssl/ca-certificates.crt, it still will not work. This specific requirement bit me as we're loading certificates from an external source.

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/)。

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。

我们最近遇到了这个错误。事实证明,这与根证书没有正确安装在CA存储目录有关。我使用了一个curl命令,其中我直接指定了CA目录。Curl——cacert /etc/test/server。—capath /etc/test…此命令每次都失败,curl: (60) SSL证书问题:无法获得本地颁发者证书。

在使用strace curl…根据openssl哈希命名约定,curl正在查找名称为60ff2731.0的根证书文件。所以我发现这个命令可以有效地导入根证书:

Ln -s rootcert。pem的openssl x509散列-noout——rootcert.pem ' 0

哪个会创建软链接

60f2731.0 ->找到脚

卷曲,在被子下读取服务器。pem,确定根证书文件的名称(rootcert.pem),将其转换为其哈希名称,然后进行操作系统文件查找,但无法找到它。

因此,结论是,当curl错误很模糊时,在运行curl时使用strace(这是一个巨大的帮助),然后确保使用openssl命名约定正确安装根证书。

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);

我的情况不同。我在防火墙后面托管一个网站。错误是由pfSense引起的。

Network layout: |Web Server 10.x.x.x| <-> |pfSense 49.x.x.x| <-> |Open Internet|

多亏了这个答案,我意外地找到了原因。


当我从广域网访问我的网站时,一切都很好。

然而,当从局域网内访问站点时(例如,当Wordpress向其自己的服务器发出curl请求时,尽管使用WAN IP 49.x.x.x),它被提供pfSense登录页面。

我将证书标识为pfSense webConfigurator自签名证书。难怪curl抛出一个错误。

原因:发生的事情是curl正在使用站点的WAN IP地址49.x.x.x。但是,在web服务器的上下文中,广域网IP是防火墙。

调试:我发现我正在获得pfSense证书。

解决方案:在托管该站点的服务器上,将其自己的域名指向127.0.0.1

通过应用该解决方案,web服务器正确地处理了curl的请求,并且没有转发到防火墙,防火墙通过发送登录页面进行响应。
