java.security.cert.certpathvalidatorexception:未找到认证路径的信任锚.在A

Question

com.android.volley.NoConnectionError: javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

我在API上的LogCat中从19至24遇到了此错误，并且在我的应用程序中没有从服务器加载数据，我搜索了该错误，并找到了该解决方案

 @SuppressLint("TrulyRandom")
public static void handleSSLHandshake() {
    try {
        TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
            public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }
            @Override
            public void checkClientTrusted(X509Certificate[] certs, String authType) {
            }
            @Override
            public void checkServerTrusted(X509Certificate[] certs, String authType) {
            }
        }};
        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String arg0, SSLSession arg1) {
                return true;
            }
        });
    } catch (Exception ignored) {
    }
}

并在我的应用程序类中称其为"解决我的问题"，但是在这个答案中，如果找到该解决方案有提示，则该代码无关紧要，不应使用！Google禁止它。

所以有人知道Google允许的替代解决方案是什么？

Answer 1

服务器上的TLS版本是什么？最有可能是1.2或更高。对于KitKat设备，默认情况下为1.2，需要启用。如果您的设备拥有Google Play服务，则可以通过此操作来完成。否则，您需要一个自定义套接字工厂类，该类别指定1.2和1.3。

如果它低于1.2，则KitKat设备将不允许连接，除非您相信所有问题的证书。它不应该较低。

Answer 2

首先，您需要生成证书文件，这是步骤

• 访问您的网站链接firefox浏览器

• 单击网站链接右侧的绿色锁

• 单击更多信息，然后查看证书

• 将出现一个新窗口，并带有两个Taps General和详细信息选择详细信息

• 单击导出以导出您的证书并保存此文件在Android项目资产中。

第二个项目应用程序类定义hurlstack变量，并在应用程序中使用下一个方法

 private void handleCertificationOnOlderDevices() {
    try {
        CertificateFactory cf = CertificateFactory.getInstance("X.509");
        InputStream caInput = new 
                            BufferedInputStream(getAssets().open("porter_cert.crt"));
        Certificate ca;
        try {
            ca = cf.generateCertificate(caInput);
            Log.d("certificate", ((X509Certificate) ca).getSubjectDN().toString());
        } finally {
            caInput.close();
        }
        String keyStoreType = KeyStore.getDefaultType();
        KeyStore keyStore = KeyStore.getInstance(keyStoreType);
        keyStore.load(null, null);
        keyStore.setCertificateEntry("ca", ca);
        String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
        tmf.init(keyStore);
        TrustManager[] trustManagers = tmf.getTrustManagers();
        final X509TrustManager origTrustmanager =  
                                                (X509TrustManager) trustManagers[0];
        TrustManager[] wrappedTrustManagers = new TrustManager[]{
                new X509TrustManager() {
                   public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                        return origTrustmanager.getAcceptedIssuers();
                   }
                   public void checkClientTrusted(X509Certificate[] certs,  
                   String authType) 
                   {
                        try {
                            origTrustmanager.checkClientTrusted(certs, authType);
                        } catch (CertificateException e) {
                            e.printStackTrace();
                        }
                    }
                    public void checkServerTrusted(X509Certificate[] certs,
                    String authType) 
                    {
                        try {
                            origTrustmanager.checkServerTrusted(certs, authType);
                        } catch (CertificateException e) {
                            e.printStackTrace();
                        }
                    }
                }
        };
        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, tmf.getTrustManagers(), null);
        SSLSocketFactory sslSocketFactory = context.getSocketFactory();
        hurlStack = new HurlStack(null, sslSocketFactory);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

和凌空请求时使用hurlstack

    public RequestQueue getRequestQueue() {
       if (requestQueue == null)
           requestQueue = Volley.newRequestQueue(getApplicationContext(), 
           hurlStack);
       return requestQueue;
    }

第三，如果您将Glide用于图像，则将获得与Glide相关的SSL证书的第二个错误，您需要以此方式解决它

1-在应用中更新构建您的gilde和okhttp3到这些版本

    implementation "com.squareup.okhttp3:okhttp:3.8.1"
    implementation 'com.github.bumptech.glide:glide:4.9.0'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
    implementation ('com.github.bumptech.glide:okhttp3-integration:4.9.0'){
    exclude group: 'glide-parent'
    }

2-将下一个类添加到您的项目

@GlideModule 
public class CustomGlideModule extends AppGlideModule {
   @Override
   public void registerComponents(Context context, Glide glide,  
   Registryregistry) {
      if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.N) {
          OkHttpClient client = 
                        SafeOkHttpClient.getSafeOkHttpClient(context);
          OkHttpUrlLoader.Factory factory = new 
                                       OkHttpUrlLoader.Factory(client);
          glide.getRegistry().replace(GlideUrl.class, InputStream.class, 
          factory);
      }
   }
 }

现在滑行将与您搭配。
