如果CURLOPT_SSLCERT被设置为同时具有证书和私钥的文件,我应该设置CURLOPT_SSLKEY吗?

服务器给了我一个客户端证书 customer.pem 我应该用它。如果我在文本编辑器中打开它,它包含客户端证书和客户端密钥:

-----BEGIN RSA PRIVATE KEY-----
here is private key
-----END RSA PRIVATE KEY-----

-----BEGIN CERTIFICATE-----
here is certificate
-----END CERTIFICATE-----

但是 according to PHP curl doc 有两个单独的选项可用于设置客户端证书和专用客户端密钥:

CURLOPT_SSLCERT The name of a file containing a PEM formatted certificate;
CURLOPT_SSLKEY  The name of a file containing a private SSL key;

有 顾客佩姆 包含证书和私钥的文件-我可以设置 CURLOPT_SSLCERT 选项CURL会自动读取客户端密钥并正确使用它吗?比如:

$curl_opt = array(
    CURLOPT_SSL_VERIFYHOST => 2,
    CURLOPT_SSL_VERIFYPEER => 1,
    CURLOPT_SSLCERT => $cert_dir . 'customer.pem',
    CURLOPT_CAINFO => $cert_dir . 'ca.crt',
    CURLOPT_SSLCERTPASSWD => $extra_settings['certificate_password'],
);
