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;
}
}

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。
@Chrispix的解决方案是危险的!相信所有的证书允许任何人做一个人在中间攻击!只要向客户端发送任何证书，它就会接受它!
将您的证书添加到自定义信任管理器，如本文所述:通过HTTPS使用HttpClient信任所有证书
虽然使用自定义证书建立安全连接有点复杂，但它将为您带来所需的ssl加密安全，而没有中间人攻击的危险!
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。

**Set proper alias name**
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509","BC");
X509Certificate cert = (X509Certificate) certificateFactory.generateCertificate(derInputStream);
String alias = cert.getSubjectX500Principal().getName();
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null);
trustStore.setCertificateEntry(alias, cert);
