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());

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'

其他回答
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。
https://stackoverflow.com/a/60102517/114265
您可以在运行时信任特定的证书。 只需从服务器下载，放入资产，然后使用ssl-utils-android像这样加载:
OkHttpClient client = new OkHttpClient();
SSLContext sslContext = SslUtils.getSslContextForCertificateFile(context, "BPClass2RootCA-sha2.cer");
client.setSslSocketFactory(sslContext.getSocketFactory());
在上面的例子中，我使用了OkHttpClient，但是SSLContext可以用于Java中的任何客户端。
如果你有任何问题，请提出来。我是这个小图书馆的作者。
在姜饼手机，我总是得到这个错误:信任锚没有找到Android SSL连接，即使我设置依赖于我的证书。
下面是我使用的代码(在Scala语言中):
object Security {
private def createCtxSsl(ctx: Context) = {
val cer = {
val is = ctx.getAssets.open("mycertificate.crt")
try
CertificateFactory.getInstance("X.509").generateCertificate(is)
finally
is.close()
}
val key = KeyStore.getInstance(KeyStore.getDefaultType)
key.load(null, null)
key.setCertificateEntry("ca", cer)
val tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm)
tmf.init(key)
val c = SSLContext.getInstance("TLS")
c.init(null, tmf.getTrustManagers, null)
c
}
def prepare(url: HttpURLConnection)(implicit ctx: Context) {
url match {
case https: HttpsURLConnection ⇒
val cSsl = ctxSsl match {
case None ⇒
val res = createCtxSsl(ctx)
ctxSsl = Some(res)
res
case Some(c) ⇒ c
}
https.setSSLSocketFactory(cSsl.getSocketFactory)
case _ ⇒
}
}
def noSecurity(url: HttpURLConnection) {
url match {
case https: HttpsURLConnection ⇒
https.setHostnameVerifier(new HostnameVerifier {
override def verify(hostname: String, session: SSLSession) = true
})
case _ ⇒
}
}
}
下面是连接代码:
def connect(securize: HttpURLConnection ⇒ Unit) {
val conn = url.openConnection().asInstanceOf[HttpURLConnection]
securize(conn)
conn.connect();
....
}
try {
connect(Security.prepare)
} catch {
case ex: SSLHandshakeException /*if ex.getMessage != null && ex.getMessage.contains("Trust anchor for certification path not found")*/ ⇒
connect(Security.noSecurity)
}
基本上，我在自定义证书上设置了信任。如果失败，我就禁用安全机制。这不是最好的选择，但这是我所知道的对于老旧和有问题的手机的唯一选择。
这个示例代码，可以很容易地翻译成Java。

有时，当管理员错误地设置证书时，会发生这种情况 点击此处查看URL https://www.sslshopper.com/ssl-checker.html
在我的例子中，出现了一个错误
证书在所有浏览器中都不受信任。您可能需要安装中间证书/链证书以将其链接到受信任的根证书。了解关于此错误的更多信息。您可以按照GlobalSign针对您的服务器平台的证书安装说明来解决这个问题。注意中级证书部分。
