Spring Security - X509 證書 JUnit 測試

Question

在這篇文章之后，我已將 X509 身份驗證添加到我的后端： https : //www.baeldung.com/x-509-authentication-in-spring-security 。 我已經在郵遞員中進行了測試，並且工作正常，我從 CN 中提取了 Principal。

我的問題是我想為此編寫 JUnit 測試，並檢查我是否可以正確提取所需的主體，但我不知道如何啟動它，如何在 Java 中創建 X509Certifcate 並將其傳遞給我的提取器函數。 如果有人可以解釋所需的步驟，我將不勝感激，謝謝。

Answer 1

您可以為您的測試創建一個測試證書，如下所示：

public static X509Certificate buildTestCertificate() throws Exception {
        String cert = "-----BEGIN CERTIFICATE-----\n"
                + "MIIEQTCCAymgAwIBAgIBATANBgkqhkiG9w0BAQUFADCBkzEaMBgGA1UEAxMRTW9u\n"

                + "W9YQkWlA6t0blGlC+ghTOY1JbgWnEfXMmVgg9a9cWaYQ+NQwqA==\n" + "-----END CERTIFICATE-----";
        ByteArrayInputStream in = new ByteArrayInputStream(cert.getBytes());
        CertificateFactory cf = CertificateFactory.getInstance("X.509");
        return (X509Certificate) cf.generateCertificate(in);
}

這段代碼是從這里提取的。

證書到位后，您可以將其傳遞給提取器函數並比較字段。
