Java证书客户端SSL:找不到请求目标的有效证书路径

我们需要客户端身份验证来向一些web服务发送RESTful请求。我已经通过密钥工具在本地mac os上安装了客户端证书（.pem）和密钥。这些不是自签名的

openssl pkcs12 -export -name myservercert -in not_self_signed.crt -inkey server.key -out keystore.p12

…并转换为JKS格式

keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert

我正在尝试构建一个Java客户端来进行身份验证。以下是我到目前为止得出的结论：

import java.io.FileInputStream;
import java.security.KeyStore;

import javax.net.ssl.SSLContext;

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.ssl.SSLContexts;
import org.apache.http.util.EntityUtils;


public class TestClientCustomSSL {

    public final static void main(String[] args) throws Exception {

        KeyStore keyStore = KeyStore.getInstance("JKS");
        keyStore.load(new FileInputStream("/Users/me/mykeystore.jks"), "mypassword".toCharArray());

        SSLContext sslContext = SSLContexts.custom().loadKeyMaterial(keyStore, "mypassword".toCharArray()).build();

        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                sslContext,
                new String[] {"TLSv1"},
                null,
                SSLConnectionSocketFactory.getDefaultHostnameVerifier());

        CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build();

        try {

            HttpGet httpget = new HttpGet("https://restful-service-i-am-calling/v1/endpoint/data?ip=0.0.0.1");

            System.out.println("Executing request " + httpget.getRequestLine());

            CloseableHttpResponse response = httpclient.execute(httpget);
            try {
                HttpEntity entity = response.getEntity();

                System.out.println("----------------------------------------");
                System.out.println(response.getStatusLine());
                EntityUtils.consume(entity);
            } finally {
                response.close();
            }
        } finally {
            httpclient.close();
        }
    }

}

下面是我收到的stacktrace。但是根据我读到的内容，我的班级应该能够发送请求

任何指点都很感激

编辑：：

仅供参考，我能够使用与我使用wget添加到信任存储的相同的pem和密钥从服务器获得200响应

wget --certificate ~/Desktop/my.cert.pem --private-key ~/Desktop/my.key.key https://mycompany.com/v1/939044?data=0.0.0.1

编辑2:：*

根据下面的@EJP应答，还从服务器站点添加了证书：

openssl x509 -in <(openssl s_client -connect the.api.i.am.calling.com:443 -prexit 2>/dev/null) -out ~/Desktop/the.api.i.am.calling.crt

运行list命令显示两个证书都在密钥库中：

keytool -importcert -file ~/Desktop/the.api.i.am.calling.crt -alias the.api.i.am.calling.com -keystore /Users/me/mykeystore.jks -storepass mypassword

keytool -list -keystore /Users/me/mykeystore.jks 
Enter keystore password:  *********

Keystore type: JKS
Keystore provider: SUN

Your keystore contains 2 entries

my.auth.client.cert.com, Oct 17, 2015, PrivateKeyEntry, 
Certificate fingerprint (SHA1): 3D:95:32:E5:F9:9E:4A:53:84:EB:AB:1B:B9:A2:4C:A5:1B:5E:DA:76
the.api.i.am.calling.com, Oct 18, 2015, trustedCertEntry, 
Certificate fingerprint (SHA1): 7C:4A:7B:CE:9B:0B:92:C0:4F:C0:DA:84:CF:F2:24:CF:99:83:0B:3F

但我仍然收到同样的错误

还有一件事我忘了提。我给服务器端团队的唯一东西就是我们的客户端证书名。。。比如dev.auth.client.com。我真的必须将服务器端证书存储在密钥库中吗？

它与您的客户端证书无关。您的信任库不信任服务器证书

使用openssl生成P12文件

openssl pkcs12-export-in/Users/me/test.authclient.int.com.crt-inkey/Users/me/test.authclient.int.com.key-out-authclient.p12-name-authClientCert

生成信任存储密钥

keytool-genkey-dname“cn=CLIENT”-别名trustStoreKey-keyalg RSA-keystore authClient-truststore.jks-keypass mypassword-storepass mypassword

现在，导入信任存储密钥

keytool-import-keystore-authClient-truststore.jks-file/Users/me/test.authClient.int.com/test.authClient.int.com.crt-alias.test.authClient.int.com

获取远程证书

openssl x509-in/dev/null）-out.api.i.want.to.call.crt

将服务器证书添加到信任存储

keytool-importcert-file the.api.i.want.to.call.crt-别名the.api.i.want.to.call.com-keystore/Users/me/authClient-truststore.jks-storepass mypassword

这是我用来调用需要身份验证的api的客户端

    KeyStore clientStore = KeyStore.getInstance("PKCS12");
    clientStore.load(new FileInputStream("/Users/me/authClient.p12"), "mypassword".toCharArray());

    KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
    kmf.init(clientStore, "mypassword".toCharArray());
    KeyManager[] keyManagers = kmf.getKeyManagers();

    KeyStore trustStore = KeyStore.getInstance("JKS");
    trustStore.load(new FileInputStream("/Users/me/authClient-truststore.jks"), "mypassword".toCharArray());

    TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
    tmf.init(trustStore);
    TrustManager[] tms = tmf.getTrustManagers();

    SSLContext sslContext = SSLContext.getInstance("TLS");
    sslContext.init(keyManagers, tms, new SecureRandom());

    SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);
    CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build();

    HttpGet httpget = new HttpGet(requestUrl);

    httpclient.execute(httpget);

不是这样。让我知道我是否可以通过扩展来帮助您，但这应该是您所需要的全部。

谢谢EJP。如果您不介意提供一些关于如何使其信任服务器证书的详细信息，这将非常有用。我在本地运行这个。真正的问题是为什么服务器证书没有签名？如果它们都是您的证书，请从服务器密钥库导出服务器证书，并使用keytool将其作为受信任证书导入到您的客户端信任库中。如果是这种情况，我是否能够发送此证书？从我当地的经验来看，效果很好。wget--certificate~/Desktop/my.cert.pem--private key~/Desktop/my.key.key我已将服务器证书添加到密钥库中。编辑2显示此更新。。。还是一样的结果。任何额外的建议我都很感激。我无法理解这一点。步骤1不使用keytool。步骤2生成一个密钥对，该密钥对位于密钥库中。步骤3导入证书，而不是密钥。客户机密钥库和信任库都混在一起了。步骤4-5正是你所说的不起作用的。我相信其他人会发现这一点useful@MattB，谢谢你的解决方案。这是唯一适用于authClient身份验证的方法。
