“PKIX路径构建失败”和“无法找到请求目标的有效认证路径”

我试图使用twitter4j库为我的java项目获得推文，它在封面下使用java.net.HttpURLConnection(可以在堆栈跟踪中看到)。在我第一次运行时，我得到了一个关于证书sun.security.validator.ValidatorException和sun.security.provider.certpath.SunCertPathBuilderException的错误。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"

但是没有成功。以下是获取推文的流程:

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() + " : " + tweet.getText());
        }
    } catch (TwitterException te) {
        te.printStackTrace();
        System.out.println("Failed to search tweets: " + te.getMessage());
    }

这里是错误:

当前回答

如果你的主机位于防火墙/代理之后，在cmd中使用以下命令:

keytool -J-Dhttps.proxyHost=<proxy_hostname> -J-Dhttps.proxyPort=<proxy_port> -printcert -rfc -sslserver <remote_host_name:remote_ssl_port>

将<proxy_hostname>和<proxy_port>替换为已配置的HTTP代理服务器。将<remote_host_name:remote_ssl_port>替换为一个存在认证问题的远程主机(基本上是url)和端口。

将上次打印的证书内容复印一份(同时复印开始证书和结束证书)。将其粘贴到文本文件中，并将扩展名为.crt。现在使用java keytool命令将该证书导入cacerts，它应该可以工作。

keytool -importcert -file <filename>.crt -alias randomaliasname -keystore %JAVA_HOME%/jre/lib/security/cacerts -storepass changeit

其他回答

我留下一些小费。

使用- dsll .debug=true检查SSL。 检查您是否正在创建隧道或试图忽略它

SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, (x509CertChain, authType) -> true).build();
            httpClient = HttpClientBuilder.create()
                    .setSSLContext(sslContext)
                    .setConnectionManager(new PoolingHttpClientConnectionManager(RegistryBuilder.<ConnectionSocketFactory>create()
                            .register("http", PlainConnectionSocketFactory.INSTANCE)
                            .register("https", new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE))
                            .build()
                    )).build();

httpClient.execute(requisicao)

这是针对Glassfish服务器的:

通常Glassfish会看着仙人掌。证书文件存放在GLASSFISH_SERVER\glassfish\domains\domain1\config目录下。您可以更改此配置或替换cacerts。JKS文件和cacerts文件。

Glassfish使用了一些默认的JVM选项:

 -XX:+UnlockDiagnosticVMOptions
 -XX:NewRatio=2
 -XX:MaxPermSize=192m
 -Xmx512m
 -client
 -javaagent:C:/glassfish5/glassfish/lib/monitor/flashlight-agent.jar
 -Djavax.xml.accessExternalSchema=all
 -Djavax.net.ssl.trustStore=C:\glassfish5\glassfish\domains\domain1/config/cacerts.jks
 -Djdk.tls.rejectClientInitiatedRenegotiation=true
 -Djdk.corba.allowOutputStreamSubclass=true

我在ubuntu 15.10上也有同样的问题。请尝试在本地下载插件，例如https://github.com/lmenezes/elasticsearch-kopf/archive/master.zip，并使用以下命令安装:

sudo /usr/share/elasticsearch/bin/plugin install file:/home/dev/Downloads/elasticsearch-kopf-master.zip

路径可能不同，取决于你的环境。

的问候。

当你有上述错误与atlassian软件exjira

2018-08-18 11:35:00,312 Caesium-1-4 WARN anonymous    Default Mail Handler [c.a.mail.incoming.mailfetcherservice] Default Mail Handler[10001]: javax.mail.MessagingException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target while connecting to host 'imap.xyz.pl' as user 'jira@xyz.pl' via protocol 'imaps, caused by: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

您可以将证书添加到它的可信密钥存储库(将missing_ca更改为正确的证书名称):

keytool -importcert -file missing_ca.crt -alias missing_ca -keystore /opt/atlassian/jira/jre/lib/security/cacerts

如果要求输入密码，输入changeit并确认y

之后，只需重启jira。

对我来说，证书错误弹出是因为我有fiddler运行在后台，这打乱了证书。它作为一个代理如此接近，并重新启动eclipse。
