如何忽略PKIX路径构建失败: sun.security.provider.certpath.SunCertPathBuilderException？
如何忽略PKIX路径构建失败: sun.security.provider.certpath.SunCertPathBuilderException？
提问于 2012-11-29 21:32:14
当我尝试向http服务器发送请求时，我得到了以下异常：
下面是我使用的代码
URL url = new URL(
"https://www.abc.com");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
// wr.writeBytes(params);
wr.flush();
wr.close();
BufferedReader br = new BufferedReader(new InputStreamReader(
conn.getInputStream()));
String line = null;
while ((line = br.readLine()) != null) {
System.out.println(line);
}以下是例外情况：

如果你想忽略所有的证书，那么看看这里的答案：Ignore self-signed ssl cert using Jersey Client
尽管这会使你的应用程序容易受到中间人攻击。
或者，尝试将证书作为受信任的证书添加到java存储中。这个网站可能会有帮助。http://blog.icodejava.com/tag/get-public-key-of-ssl-certificate-in-java/
这是另一个展示如何向你的商店添加证书的线程。Java SSL connect, add server cert to keystore programmatically
关键是：
KeyStore.Entry newEntry = new KeyStore.TrustedCertificateEntry(someCert);
ks.setEntry("someAlias", newEntry, null);Stack Overflow用户

我已经使用下面的代码覆盖了我的项目中的SSL检查，它对我很有效。
package com.beingjavaguys.testftp;
import java.io.InputStreamReader;
import java.io.Reader;
import java.net.URL;
import java.net.URLConnection;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import java.security.cert.X509Certificate;
/**

*/
public class ConnectToHttpsUrl {
public static void main(String[] args) throws Exception {
/* Start of Fix */
TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() { return null; }
public void checkClientTrusted(X509Certificate[] certs, String authType) { }
public void checkServerTrusted(X509Certificate[] certs, String authType) { }
} };
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
// Create all-trusting host name verifier
HostnameVerifier allHostsValid = new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) { return true; }
};
// Install the all-trusting host verifier
HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
/* End of the fix*/
URL url = new URL("https://nameofthesecuredurl.com");
URLConnection con = url.openConnection();
Reader reader = new InputStreamReader(con.getInputStream());
while (true) {
int ch = reader.read();
if (ch == -1)
break;
System.out.print((char) ch);
}
}

将JSoup命令的validateTLSCertificates属性设置为false。
Jsoup.connect("https://google.com/").validateTLSCertificates(false).get();页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
