自己証明のSSLを利用しているURLに対して、curlでリクエストする

More than 5 years have passed since last update.

概要

検証環境などで、自己証明のSSLを利用している場合、curlでリクエストする場合insecureオプションが必要になります。

オプションなし

% curl https://dev.xxxxx.com/ --max-time 10 --verbose
* Hostname was NOT found in DNS cache
*   Trying XXX.XXX.XX.XX...
* Connected to dev.buyma.com (XXX.XXX.XX.XX) port 443 (#0)
* SSL certificate problem: Invalid certificate chain
* Closing connection 0
curl: (60) SSL certificate problem: Invalid certificate chain
More details here: http://curl.haxx.se/docs/sslcerts.html

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.

* TLS 1.0 connection using TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
* Server certificate: dev.xxxxx.com
