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());

如果你使用了改装,你需要定制你的OkHttpClient。

retrofit =新的retrofit . builder () .baseUrl (ApplicationData.FINAL_URL) .build .client (getUnsafeOkHttpClient () ()) .addConverterFactory (GsonConverterFactory.create ()) .build ();

完整代码如下。

public class RestAdapter {

    private static Retrofit retrofit = null;
    private static ApiInterface apiInterface;

    public static OkHttpClient.Builder 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();
    
                OkHttpClient.Builder builder = new OkHttpClient.Builder();
                builder.sslSocketFactory(sslSocketFactory, (X509TrustManager) trustAllCerts[0]);
                builder.hostnameVerifier(new HostnameVerifier() {
                    @Override
                    public boolean verify(String hostname, SSLSession session) {
                        return true;
                    }
                });
                return builder;
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        }
        
        public static ApiInterface getApiClient() {
            if (apiInterface == null) {
    
                try {
                    retrofit = new Retrofit.Builder()
                            .baseUrl(ApplicationData.FINAL_URL)
                            .client(getUnsafeOkHttpClient().build())
                            .addConverterFactory(GsonConverterFactory.create())
                            .build();
    
                } catch (Exception e) {
    
                    e.printStackTrace();
                }
    
    
                apiInterface = retrofit.create(ApiInterface.class);
            }
            return apiInterface;
        }
        
    }

其他回答

In my case, the root & intermediate certificates was successfully installed but I still got "Trust anchor for certification path not found." exception!. After digging the android document, found out that by default, secure connections (using protocols like TLS and HTTPS) from all apps trust the pre-installed system CAs, and apps targeting Android 6.0 (API level 23) and lower also trust the user-added CA store by default. If your app running on a OS with api level higher than 23 you should explicitly allow the app to trust user-added CA by adding its address to network_security_config like bellow:

<domain-config>
        <domain includeSubdomains="true">PUT_YOUR_SERVER_ADDERESS</domain>
        <trust-anchors>
            <certificates src="user" />
        </trust-anchors>
</domain-config>

根据最新的Android文档(2017年3月)更新:

当你得到这种类型的错误:

javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
        at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.startHandshake(OpenSSLSocketImpl.java:374)

        at libcore.net.http.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:271)

问题可能是以下情况之一:

颁发服务器证书的CA未知 服务器证书不是由CA签署的,而是自签署的 服务器配置缺少一个中间CA

解决方案是教会HttpsURLConnection信任一组特定的ca。怎么做?请查看https://developer.android.com/training/articles/security-ssl.html#CommonProblems

其他使用com.loopj的AsyncHTTPClient的人。android:android-async-http库,请检查设置AsyncHttpClient使用HTTPS。

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。

我有同样的问题,我发现我提供的证书.crt文件缺少一个中间证书。所以我从我的服务器管理员那里询问了所有的.crt文件,然后按相反的顺序将它们连接起来。

前女友。 1. crt 2. Inter.crt 3.myCrt.crt

在Windows中执行 复制国际米兰。crt + Root。crt newCertificate.crt

(这里我忽略了myCrt.crt)

然后我提供了newCertificate。CRT文件通过输入流转换成代码。 工作。

在我的例子中,这发生在更新到Android 8.0之后。Android设置为信任的自签名证书使用的是签名算法SHA1withRSA。切换到新的证书,使用签名算法sha256withthrsa解决了这个问题。
