Java HTTP(S)客户端未失败

Question

我使用Apache HTTP组件库：

有Java SE Desktop（Console）应用程序

<dependency org="org.apache.httpcomponents" name="httpcore" rev="4.4.5"/>

在最低层，我只是在做：

CloseableHttpClient httpClient = HttpClients.custom().setDefaultHeaders(headers).build();
CloseableHttpResponse response = httpClient.execute(request); 

我然后使用此控制台应用程序访问通过SSL提供的Web服务以及使用以下证书配置服务器的地方：

Common Name (CN)    InCommon RSA Server CA
Organization (O)    Internet2
Organizational Unit (OU)    InCommon

我期望我的客户失败。这是因为当我查看与Java捆绑在一起的证书时，与" Internet2"或" Inc"一无所有：

：

$ keytool -keystore /usr/lib/jvm/java-8-oracle/jre/lib/security/cacerts -list | grep -i 'internet2|inc'
Enter keystore password:  
<no output>
$

为什么我的客户不失败？我尚未将其配置为接受所有证书。过去（当服务器完全没有证明证书时）代码确实失败了，但我期望有了新证书，情况将保持不变，因为在Java的cacerts文件中未列出Incommon CA。/p>

使用keytool -printcert -sslserver hostname[:port]的建议非常有用。

我仍然不太清楚如何解读keytool -printcert -sslserver的输出以及如何将其与keytool -printcert的输出"连接"。以下（脆性）咒语确实找到了一些匹配：

for x in $(keytool -printcert -sslserver example.com:443 -v | grep ^Issuer | awk '{print $2}' | cut -c4- | sort | uniq); do keytool -keystore /usr/lib/jvm/java-8-oracle/jre/lib/security/cacerts -list   | grep -i $x; done

＆hellip;但是，匹配是不敏感的，仅在前缀上。

尤其是keytool -printcert -sslserver的输出具有字符串" UserTrust"，但keytool -keystore的输出最接近的是：" usertrusteccca"one_answers" userTroustrustrSaca"。

`keytool -printcert -sslserver'的输出

$ keytool -printcert -sslserver example.com:443 -v | grep -i usertrust

`keytool -keystore`的输出

$ keytool -keystore /usr/lib/jvm/java-8-oracle/jre/lib/security/cacerts -list   | grep -i usertrust
