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.

尝试在Ubuntu中重新安装curl,并使用sudo update-ca-certificates—fresh更新我的CA证书

其他回答

这可以帮助你控制暴饮暴食:

$client = new Client(env('API_HOST'));
$client->setSslVerification(false);

测试在guzzle/guzzle 3.*

以我为例,在我试图用cURL使用的服务上安装我的证书时出现了问题。我未能将中间证书和根证书捆绑/连接到我的域证书。一开始并没有明显的问题,因为Chrome解决了这个问题并接受了证书,尽管省略了中间证书和根证书。

在捆绑证书之后,一切都按预期工作。我捆扎成这样

$ cat intermediate.crt >> domain.crt

并对所有中间证书和根证书重复。

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。

尝试在Ubuntu中重新安装curl,并使用sudo update-ca-certificates—fresh更新我的CA证书

仅仅更新证书列表可能就足够了

sudo update-ca-certificates -f

update-ca-certificates是一个更新/etc/ssl/certs目录以保存SSL证书并生成ca-certificates的程序。Crt,一个连接的证书单文件列表。
