<p>前章でOpenSSLのセットアップが済んだので、さっそくHTTPSクライアントを使ってみましょう。2章で使った <code>httplib::Client</code> がそのまま使えます。コンストラクタに <code>https://</code> 付きのURLを渡すだけです。</p>
|
||||
<h2>GETリクエスト</h2>
|
||||
<p>実在するHTTPSサイトにアクセスしてみましょう。</p>

<h2>CA証明書の検証</h2>
|
||||
<p><code>httplib::Client</code> はHTTPS接続時、デフォルトでサーバー証明書を検証します。信頼できるCA（認証局）が発行した証明書を持つサーバーにしか接続しません。</p>
|
||||
<p>CA証明書は、macOSならKeychain、LinuxならシステムのCA証明書ストア、WindowsならWindowsの証明書ストアから自動で読み込みます。ほとんどの場合、追加の設定は要りません。</p>
|
||||
<h3>CA証明書ファイルの指定</h3>
|
||||
<p>環境によってはシステムのCA証明書が見つからないこともあります。そのときは <code>set_ca_cert_path()</code> でパスを直接指定してください。</p>
