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.

这可以帮助你控制暴饮暴食:

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

在所有的ca中，我对Digicert有这个问题。我创建了一个数字文件。Pem文件，只是中间和根粘贴到一个文件。

curl https://cacerts.digicert.com/DigiCertGlobalRootCA.crt.pem
curl https://cacerts.digicert.com/DigiCertSHA2SecureServerCA.crt.pem

curl -v https://mydigisite.com/sign_on --cacert DigiCertCA.pem
...
*  subjectAltName: host "mydigisite.com" matched cert's "mydigisite.com"
*  issuer: C=US; O=DigiCert Inc; CN=DigiCert SHA2 Secure Server CA
*  SSL certificate verify ok.
> GET /users/sign_in HTTP/1.1
> Host: mydigisite.com
> User-Agent: curl/7.65.1
> Accept: */*
...

我通过在cURL脚本中添加一行代码解决了这个问题:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

警告:这使得请求绝对不安全(参见@YSU的回答)!

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。

我的方法是在旋度上加-k。没必要把事情复杂化。
