CXF RESTful 客户端 - 如何信任所有证书？

Question

我编写了 Jersey RESTful 客户端，它们使用 Dumb X509TrustManager 和 HostnameVerifier 来信任我们实验室系统上的所有 SSL 证书，以便更轻松地处理自签名证书。

        ClientConfig config = new DefaultClientConfig();
        SSLContext context = null;
        try
        {
            context = SSLContext.getInstance("SSL");
            context.init(null,
                    new TrustManager[] { new DumbX509TrustManager() },
                    null);
            config.getProperties()
                    .put(HTTPSProperties.PROPERTY_HTTPS_PROPERTIES,
                            new HTTPSProperties(this.getHostnameVerifier(),
                                    context));
            webClient = Client.create(config);
        }
        ....

有没有办法让我使用 CXF 做类似的事情？

Answer 1

这是来自 CXF 邮件列表。请注意，由于其他系统更新，我不必实现它，所以这是理论上的：

WebClient webClient = WebClient.create(this.serviceURL,
    this.username,
    this.password,
    null); // Spring config file - we don't use this

if (trustAllCerts)
{
    HTTPConduit conduit = WebClient.getConfig(webClient)
        .getHttpConduit();

    TLSClientParameters params = 
        conduit.getTlsClientParameters();

    if (params == null) 
    {
        params = new TLSClientParameters();
        conduit.setTlsClientParameters(params);
    }

    params.setTrustManagers(new TrustManager[] { new
        DumbX509TrustManager() }); 

    params.setDisableCNCheck(true);
}

为了完成 sdoca 的答案，这里是一个使用哑 X509 信任管理器的实现：

import org.apache.cxf.configuration.jsse.TLSClientParameters;
import org.apache.cxf.jaxrs.client.WebClient;
import org.apache.cxf.transport.http.HTTPConduit;
[...]

public class ApiClient {

    private WebClient webClient;
    [...]

    public void init() {

        webClient = createWebClient(URI).accept(MediaType.APPLICATION_JSON).type(MediaType.APPLICATION_JSON);
        addX509TrustManager();
    }

    private void addX509TrustManager() {
        Assert.notNull(webClient, "Client needs to be initialized");
        HTTPConduit conduit = WebClient.getConfig(webClient).getHttpConduit();
        TLSClientParameters params = conduit.getTlsClientParameters();

        if (params == null) {
            params = new TLSClientParameters();
            conduit.setTlsClientParameters(params);
        }

        params.setTrustManagers(new TrustManager[] { new BlindTrustManager() });
        params.setDisableCNCheck(true);
    }

}

其中 BlindTrustManager 定义如下：

import java.security.cert.X509Certificate;
import javax.net.ssl.X509TrustManager;

/**
 * This dumb X509TrustManager trusts all certificate. TThis SHOULD NOT be used in Production. 
 */
public class BlindTrustManager implements X509TrustManager {

    @Override
    public void checkClientTrusted(X509Certificate[] chain,
            String authType) throws java.security.cert.CertificateException {
    }

    @Override
    public void checkServerTrusted(X509Certificate[] chain,
            String authType) throws java.security.cert.CertificateException {
    }

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }
}
