我正在尝试使用twitter4j库为我的java项目发送推文.在我第一次运行时,我收到了关于证书sun.security.validator.ValidatorException和错误的错误sun.security.provider.certpath.SunCertPathBuilderException.然后我添加了twitter证书:
C:\Program Files\Java\jdk1.7.0_45\jre\lib\security>keytool -importcert -trustcacerts -file PathToCert -alias ca_alias -keystore "C:\Program Files\Java\jdk1.7.0_45\jre\lib\security\cacerts"
但没有成功.这是获得twitters的过程:
public static void main(String[] args) throws TwitterException {
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey("myConsumerKey")
.setOAuthConsumerSecret("myConsumerSecret")
.setOAuthAccessToken("myAccessToken")
.setOAuthAccessTokenSecret("myAccessTokenSecret");
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getInstance();
try {
Query query = new Query("iphone");
QueryResult result;
result = twitter.search(query);
System.out.println("Total amount of tweets: " + result.getTweets().size());
List<Status> tweets = result.getTweets();
for (Status tweet : tweets) {
System.out.println("@" + tweet.getUser().getScreenName() + " …它看起来像一个标准问题,但我无法在任何地方找到明确的方向.
我有java代码尝试连接到可能具有自签名(或过期)证书的服务器.代码报告以下错误:
[HttpMethodDirector] I/O exception (javax.net.ssl.SSLHandshakeException) caught
when processing request: sun.security.validator.ValidatorException: PKIX path
building failed: sun.security.provider.certpath.SunCertPathBuilderException:
unable to find valid certification path to requested target
据我了解,我必须使用keytool并告诉java允许这种连接是可以的.
解决此问题的所有说明都假设我完全熟练使用keytool,例如
为服务器生成私钥并将其导入密钥库
有没有人可以发布详细说明？
我正在运行unix,所以bash脚本最好.
不确定它是否重要,但代码是在jboss中执行的.
我在本地计算机上生成证书时遇到以下错误.
C:\Users\abc>keytool -genkey -alias tomcat -keyalg RSA
Enter keystore password:
keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect
我认为在jdk版本中存在一些问题.我在我的同事机器上运行了相同的命令,它运行正常.
请分享您的意见.
当我使用命令
C:\>keytool -list -alias androiddebugkey
-keystore .android\debug.keystore
-storepass android -keypass android
我收到此错误:
'keytool'不被识别为内部或外部命令,可操作程序或批处理文件.
我无法在计算机上获取证书指纹(MD5).
我确保密钥库文件存在于适当的位置.
有帮助吗？
我知道,关于这个问题有很多不同的问题和很多答案...但我无法理解......
我有:ubuntu-9.10-desktop-amd64 + NetBeans6.7.1从"关闭"安装.代表.我需要通过HTTPS连接到某个站点.为此我使用Apache的HttpClient.
从教程我读到:
"一旦正确安装了JSSE,通过SSL进行安全的HTTP通信
就像普通的HTTP通信一样简单." 还有一些例子:
HttpClient httpclient = new HttpClient();
GetMethod httpget = new GetMethod("https://www.verisign.com/");
try {
httpclient.executeMethod(httpget);
System.out.println(httpget.getStatusLine());
} finally {
httpget.releaseConnection();
}
到现在为止,我写道:
HttpClient client = new HttpClient();
HttpMethod get = new GetMethod("https://mms.nw.ru");
//get.setDoAuthentication(true);
try {
int status = client.executeMethod(get);
System.out.println(status);
BufferedInputStream is = new BufferedInputStream(get.getResponseBodyAsStream());
int r=0;byte[] buf = new byte[10];
while((r = is.read(buf)) > 0) {
System.out.write(buf,0,r);
}
} catch(Exception ex) {
ex.printStackTrace();
}
结果我有一组错误:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable …如何使用Apache HttpClient 4.0 绕过无效的SSL证书错误？
我正在使用Java 6,并尝试HttpsURLConnection使用客户端证书创建针对远程服务器.
服务器使用自签名根证书,并要求提供受密码保护的客户端证书.我已将服务器根证书和客户端证书添加到我在/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/lib/security/cacerts(OSX 10.5)中找到的默认java密钥库中.密钥库文件的名称似乎表明客户端证书不应该进入那里？
无论如何,将根证书添加到这个商店解决了臭名昭着的问题 javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed' problem.
但是,我现在仍然坚持如何使用客户端证书.我尝试了两种方法,并没有让我到任何地方.
首先,首选,尝试:
SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
URL url = new URL("https://somehost.dk:3049");
HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
conn.setSSLSocketFactory(sslsocketfactory);
InputStream inputstream = conn.getInputStream();
// The last line fails, and gives:
// javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
我试过跳过HttpsURLConnection类(不理想,因为我想与服务器谈论HTTP),而是这样做:
SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
SSLSocket sslsocket = (SSLSocket) sslsocketfactory.createSocket("somehost.dk", 3049);
InputStream inputstream = sslsocket.getInputStream();
// do anything with the inputstream results in:
// java.net.SocketTimeoutException: Read timed out
我甚至不确定客户端证书是否存在问题.
我有一个Java Web服务客户端,它通过HTTPS使用Web服务.
import javax.xml.ws.Service;
@WebServiceClient(name = "ISomeService", targetNamespace = "http://tempuri.org/", wsdlLocation = "...")
public class ISomeService
extends Service
{
public ISomeService() {
super(__getWsdlLocation(), ISOMESERVICE_QNAME);
}
当我连接到服务URL(https://AAA.BBB.CCC.DDD:9443/ISomeService)时,我得到了异常java.security.cert.CertificateException: No subject alternative names present.
为了解决这个问题,我首先运行openssl s_client -showcerts -connect AAA.BBB.CCC.DDD:9443 > certs.txt并在文件中获得以下内容certs.txt:
CONNECTED(00000003)

尝试将请求发布到http服务器时,我收到以下异常:
这是我使用的代码
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);
}
