java - TrustManagerFactory - 忽略证书检查

Question

我正在使用一个库连接到 Azure，它使用 okhttp3 来处理连接。 该库的一部分调用 okhttp3.internal.Util#platformTrustManager:

 public static X509TrustManager platformTrustManager() {
        try {
            TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
            trustManagerFactory.init((KeyStore)null);
            TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();
            if (trustManagers.length == 1 && trustManagers[0] instanceof X509TrustManager) {
                return (X509TrustManager)trustManagers[0];
            } else {
                throw new IllegalStateException("Unexpected default trust managers:" + Arrays.toString(trustManagers));
            }
        } catch (GeneralSecurityException var2) {
            throw assertionError("No System TLS", var2);
        }
    }

还有javax.net.ssl.TrustManagerFactory#getInstance(java.lang.String):

public static final TrustManagerFactory getInstance(String var0) throws NoSuchAlgorithmException {
        Instance var1 = GetInstance.getInstance("TrustManagerFactory", TrustManagerFactorySpi.class, var0);
        return new TrustManagerFactory((TrustManagerFactorySpi)var1.impl, var1.provider, var0);
    }

由于某种原因，我收到javax.net.ssl.SSLHandshakeException:sun.security.validator.ValidatorException:PKIX路径构建失败:sun.security.provider.certpath.SunCertPathBuilderException:无法找到有效的证书路径达到要求的目标

证书在sun.security.ssl.ClientHandshaker#serverCertificate处进行验证:

 ((X509ExtendedTrustManager)var6).checkServerTrusted((X509Certificate[])var2.clone(), var4, this.conn);

这是一个真正有效的证书，但错误仍然存​​在。

我不知道如何解决这个问题。我想完全禁用证书验证，但我似乎也找不到在此设置中执行此操作的方法。

为什么有效的证书会抛出此错误？

如何“安装”此证书(我只能通过调试以文本形式获取它)，或禁用验证？

此外，我正在 Windows 上运行它。

已关注 Synoli's answer and great explanation我成功地加载了正确的 Windows 证书存储:

System.setProperty("javax.net.ssl.trustStore", "NUL");
System.setProperty("javax.net.ssl.trustStoreType", "Windows-ROOT");

我不确定 Windows 中如何保存和分隔证书，但如果没有此修复，则会加载大量证书，但我需要的证书除外。
