为什么我得到一个异常javax.net.ssl.SSLPeerUnverifiedException:peer未经过身份验证？

Question

我正在使用Apache HttpComponents HttpClient(4.0.1)进行HTTPS调用,但我将此异常作为响应:

 javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
        at com.sun.net.ssl.internal.ssl.SSLSessionImpl.getPeerCertificates(SSLSessionImpl.java:345)
        at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:128)
        at org.apache.http.conn.ssl.SSLSocketFactory.connectSocket(SSLSocketFactory.java:390)
        at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:148)
        at org.apache.http.impl.conn.AbstractPoolEntry.open(AbstractPoolEntry.java:149)
        at org.apache.http.impl.conn.AbstractPooledConnAdapter.open(AbstractPooledConnAdapter.java:121)
        at org.apache.http.impl.client.DefaultRequestDirector.tryConnect(DefaultRequestDirector.java:561)
        at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:415)
        at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:820)
        at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:754)
        at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:732)

我提供了所有必需的参数.目标系统不需要任何用户名/密码或代理,但它包含安装在服务器中的JKS证书.用户名和密码是空值.

这是使用org.apache.commons.httpclient.methods.PostMethod- 版本3.0 - commons-httpclient-3.0.jar现在我们实现了org.apache.http.client.methods.HttpPost- 版本4.0.1 - commons-httpclient.jar

这是不起作用的示例代码段:

HttpParams param = new BasicHttpParams();
HttpProtocolParams.setVersion(param, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(param, "UTF-8");
HttpProtocolParams.setUseExpectContinue(param, true);
DefaultHttpClient httpClient = new DefaultHttpClient(param);
httpClient.getParams().setParameter(HttpConnectionParams.CONNECTION_TIMEOUT,10000)));
httpClient.getParams().setParameter(HttpConnectionParams.SO_TIMEOUT,10000)));
httpClient.getCredentialsProvider().setCredentials(new AuthScope(<HOST IP,PORT)),
    AuthScope.ANY_REALM),
    new UsernamePasswordCredentials("", ""));

try {
HttpPost httpPost = new HttpPost(END POINT URL);
StringEntity requestEntity = new StringEntity(inputString, "text/xml", "UTF-8");
httpPost.setEntity(requestEntity);
response = httpClient.execute(httpPost);
HttpEntity responseEntity = response.getEntity();
if (null != responseEntity) 
{
    responseBody = EntityUtils.toString(responseEntity);
}
if (null != httpPost.getURI()) {
    url = httpPost.getURI().toString();
}
} catch (IOException e) {
    e.printStackTrace();
} finally {
   httpClient.getConnectionManager().shutdown();
}

Answer 1

异常消息

javax.net.ssl.SSLPeerUnverifiedException:peer未经过身份验证

并不总是表明问题的根本原因.您可能需要通过添加Java VM参数来启用SSL握手调试-Djavax.net.debug=ssl:handshake.添加完成后,您将收到更多有用的错误消息.如果远程服务器使用不受信任的证书,您将看到以下错误消息:

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

如果是这种情况,那么@Abhishek的答案将解决问题.

Answer 2

如上所述,您要么导入证书

1. 在已放置证书的目录中启动命令提示符(例如XYZ.cer)
2. 运行以下命令只需更改活动的jre路径(请注意〜符号)

3. keytool -import -alias XYZ -file XYZ.cer -keystore C:/Program~1/Java/jdk1.6.0_23/jre/lib/security/cacerts-storepass changeit

                              OR
