为什么我得到一个异常javax.net.ssl.SSLPeerUnverifiedException：peer未经过身份验证？ [英] Why am I getting an exception javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated?

问题描述

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：

I'm using Apache HttpComponents HttpClient(4.0.1) to make a HTTPS call, but I'm this exception as the response:

 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.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。

I provided all the required paramters. The destination system doesn't require any user name/password or proxy, but it contains JKS csrtificates that are installed in server. The user name and passwords are blank values.

这适用于 org.apache.commons.httpclient.methods.PostMethod - 版本3.0 - commons-httpclient -3.0.jar
现在我们用 org.apache.http.client.methods.HttpPost实现了 - 版本4.0.1 - commons-httpclient.jar

This is working with org.apache.commons.httpclient.methods.PostMethod - Version 3.0 - commons-httpclient-3.0.jar Now we have implemented with org.apache.http.client.methods.HttpPost - Version 4.0.1 - commons-httpclient.jar

这是不起作用的示例代码段：

This is the sample code snippet which is not working:

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();
}

推荐答案

异常消息

javax.net.ssl.SSLPeerUnverifiedException：peer not authenticated

javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

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 -Djavax.net.debug = ssl：handshake 来启用SSL握手调试。
一旦你添加了，你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：

doesn't always indicate the root cause of the issue. You may need to enable the SSL handshake debug by adding theJava VM parameter -Djavax.net.debug=ssl:handshake. Once you've added that you will get more helpful error messages. If the remote server uses a certificate that is not trusted you will see the following error message:

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
