带有客户端证书（crt，p12）的 OkHttp：java.security.cert.CertPathValidatorException：找不到证书路径的信任锚

Question

我正在尝试使用 OKHttp 和 Retrofit 2 发出请求。此请求应通过发送证书来完成（它必须是 p12 或 crt）。我们尝试了不同的方法，但没有人让我成功。我正在使用 badssl.com 进行测试，它允许我向以下 URL 提出请求：https://client.badssl.com，并提供您可以在此处找到的证书：https://badssl.com/download/

我尝试将 p12 和 crt 包含在 assets 文件夹和项目的 raw 文件夹中，并创建了 Keystore、SSLSocketFactory 和 TrustManager。 由于这不起作用，我还尝试创建一个可以发出任何请求的不安全 OkHttpClient，但我没有成功。 在这两种情况下，我都有： “javax.net.ssl.SSLHandshakeException：java.security.cert.CertPathValidatorException：找不到证书路径的信任锚”

public static SSLContext getSSLConfig(Context context) throws CertificateException, IOException,
            KeyStoreException, NoSuchAlgorithmException, KeyManagementException {

        // Loading CAs from an InputStream
        CertificateFactory cf = null;
        cf = CertificateFactory.getInstance("X.509");

        Certificate ca;
        // I'm using Java7. If you used Java6 close it manually with finally.
        try (InputStream cert = context.getResources().openRawResource(R.raw.somecert)) {
            ca = cf.generateCertificate(cert);
        }

        // Creating a KeyStore containing our trusted CAs
        String keyStoreType = KeyStore.getDefaultType();
        KeyStore keyStore = KeyStore.getInstance(keyStoreType);
        keyStore.load(null, null);
        keyStore.setCertificateEntry("ca", ca);

        // Creating a TrustManager that trusts the CAs in our KeyStore.
        String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
        tmf.init(keyStore);

        // Creating an SSLSocketFactory that uses our TrustManager
        SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(null, tmf.getTrustManagers(), null);

        return sslContext;
    }

val client: OkHttpClient = OkHttpClient.Builder()
            .sslSocketFactory(SSLConfigUtils.getSSLConfig(MyClass.getContext()).socketFactory)
            .hostnameVerifier { _, _ -> true }
            .build()

            val retrofit = Retrofit.Builder()
                .addCallAdapterFactory(
                    RxJava2CallAdapterFactory.create())
                .addConverterFactory(
                    GsonConverterFactory.create(gson))
                .baseUrl("https://client.badssl.com/")
                .client(client)
                .build()

我希望正确地提出改造请求，但每个请求都会返回此错误：

Answer 1

在 OkHttp 中有一个 test case 用于配置客户端身份验证。它可能需要作为一个有用的示例，但您应该注意它在内存中生成证书，而不是从文件中加载它们。

相关代码在okhttp-tls模块中。

另请注意，您的 TrustManager 必须包含服务器的证书，或签署它的证书颁发机构根证书之一。
