android-java.security.cert.CertPathValidatorException：找不到证书路径的信任锚.在api上少于24

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

我从19到24在api上的logcat中遇到此错误,我的应用中没有从服务器加载数据,我搜索了该错误并发现solution

 @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onCreate中调用它,就解决了我的问题,但是在该答案中,如果找到该解决方案,则存在hint,此代码不相关,不应使用！ Google禁止使用它.

所以谁知道谷歌允许该错误的替代解决方案是什么？

解决方法:

首先,您将需要生成您的证书文件,这是步骤

>在Firefox浏览器上转到您的网站链接
>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,其中包含两个常规和详细信息
选择细节
>单击导出以导出证书并保存此文件
在android项目资产中.

项目应用程序类中的第二个定义hurlStack变量,并在应用程序中使用next方法OnCreate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();
    }

}

并在volley requestQueue上使用hurlStack

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

第三,如果您使用Glide拍摄图像,则会遇到与glide相关的ssl证书出现第二个错误,您需要通过这种方式解决

1-在应用程序中更新,将您的gilde和okhttp3构建为这些版本

    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中

@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);
      }
   }

 }

现在滑行将与您配合正常.
