Python の通信を Fiddler で見る

Posted at

az コマンドの通信を HTTPS デコードして Fiddler で見たかったけど Python は Windows の証明書ストアを見ないらしく、Fiddler のルート証明書を信頼できずに証明書エラーが発生した。

Please ensure you have network connection. Error detail: 
HTTPSConnectionPool(host='login.microsoftonline.com', port=443): Max retries exceeded with url: /common/oauth2/token (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')],)",),))

解決策

Fiddler の Root 証明書を環境変数 CURL_CA_BUNDLE にセットする。

$env:CURL_CA_BUNDLE = "C:\Path\To\FiddlerRoot.cer"

なお、ルート証明書は Base64 エンコードである必要がある。
証明書ストアから、Base64 でエクスポートするのが楽。

あとは環境変数に Fiddler のプロキシをセット

$env:http_proxy = "http://127.0.0.1:8888"
$env:https_proxy = $env:http_proxy

これで Fiddler で通信トレースを取れる。
