没有为Android SSL连接找到信任锚

我试图连接到一个运行godaddy 256bit SSL证书的IIS6盒子，我得到了错误:

java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

我一直在想是什么原因导致的，但目前还没有头绪。

以下是我的联系方式:

HttpsURLConnection conn;              
conn = (HttpsURLConnection) (new URL(mURL)).openConnection();
conn.setConnectTimeout(20000);
conn.setDoInput(true);
conn.setDoOutput(true);
conn.connect();
String tempString = toString(conn.getInputStream());

当前回答

我使用这些方法，其中一个是上述解决方案对我有效: 第一:

   public  okhttp3.OkHttpClient getUnsafeOkHttpClient() {
    try {
        // Create a trust manager that does not validate 
   certificate chains
        final TrustManager[] trustAllCerts = new TrustManager[] {
                new X509TrustManager() {
                    @Override
                    public void 
   checkClientTrusted(java.security.cert.X509Certificate[] chain, 
   String authType) throws CertificateException {
                    }

                    @Override
                    public void 
  checkServerTrusted(java.security.cert.X509Certificate[] chain, 
  String authType) throws CertificateException {
                    }

                    @Override
                    public java.security.cert.X509Certificate[] 
   getAcceptedIssuers() {
                        return new 
  java.security.cert.X509Certificate[]{};
                    }
                }
        };

        // Install the all-trusting trust manager
        final SSLContext sslContext = 
  SSLContext.getInstance("SSL");
        sslContext.init(null, trustAllCerts, new 
  java.security.SecureRandom());

        // Create an ssl socket factory with our all-trusting 
       manager
        final SSLSocketFactory sslSocketFactory = 
       sslContext.getSocketFactory();

        okhttp3.OkHttpClient.Builder builder = new 
      okhttp3.OkHttpClient.Builder();
        builder.sslSocketFactory(sslSocketFactory, 
      (X509TrustManager)trustAllCerts[0]);
        builder.hostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession 
       session) {
                return true;
            }
        });

        okhttp3.OkHttpClient okHttpClient = builder.build();
        return okHttpClient;
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

第二:

    @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) {
    }
}

和: 把这些库放到你的类路径中:

 implementation 'com.squareup.okhttp:okhttp:2.3.0'
implementation 'com.squareup.okhttp:okhttp-urlconnection:2.3.0'
    androidTestImplementation 'androidx.test.espresso:espresso- 
    core:3.3.0'

一定要在课堂上给他们打电话

其他回答

我得到的错误消息与此类似，但原因是自签名证书已经过期。当尝试openssl客户端时，它给了我一个原因，当我在firefox中检查证书对话框时忽略了这个原因。

因此，通常情况下，如果证书在密钥存储库中并且它是“VALID”，则此错误将消失。

我在从Android客户端连接到Kurento服务器时遇到了同样的问题。 Kurento服务器使用jks证书，所以我必须将pem转换为它。作为转换的输入，我使用cert.pem文件，它会导致这样的错误。但如果使用全链。pem，而不是cert.pem - all是OK的。

复述你的陈词滥调 var httpClient = new httpClient (new System.Net.Http.HttpClientHandler());

将https更改为http

我知道这是一篇非常古老的文章，但我在尝试解决信任锚问题时遇到了这篇文章。我已经发布了我是如何修复它的。如果您已经预安装了根CA，则需要向清单中添加配置。
