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

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.

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。

复述你的陈词滥调 var httpClient = new httpClient (new System.Net.Http.HttpClientHandler());
将https更改为http
**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);
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。
