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。

其他回答

有这个问题,但新版本没有解决。/etc/certs有根证书,浏览器说一切正常。经过一些测试后,我从ssllabs.com得到警告,我的链是不完整的(实际上这是旧证书链,而不是新证书链)。在纠正了证书链之后,一切都很好,即使是curl。

根据cURL文档,您还可以将证书传递给cURL命令:

获取可以验证远程服务器的CA证书并使用 适当的选项指出此CA证书进行验证时 连接。对于libcurl黑客:curl_easy_setopt(curl, CURLOPT_CAPATH capath); 使用curl命令行工具:——cacert[文件]


例如:

curl --cacert mycertificate.cer -v https://www.stackoverflow.com

对我来说,简单地安装证书有帮助:

sudo apt-get install ca-certificates

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);
