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
产生信任锚错误的原因有很多。对我来说，我只是想访问https://example.com/而不是https://www.example.com/。
因此，在开始构建自己的信任管理器(就像我做的那样)之前，您可能需要仔细检查您的url。
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;
}
}
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。
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:

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。
