java - SSL 握手异常

Question

我正在使用 Apache HttpClient(4.0) 与 HTTP 服务器(已配置 SSL)通信。

服务器正在使用自签名证书。理想情况下，我希望 HttpClient 库的行为方式与浏览器相同，但在搜索了一些 google 之后，我了解到我必须将证书导入 JRE keystore (cacert)。尽管在 JRE keystore 中安装了证书，但我仍然收到“SSLHandshake 异常”。

这是一个SSL日志，我不是这方面的专家，所以需要帮助分析日志的内容。

这是我正在使用的代码片段。

DefaultHttpClient httpClient = new DefaultHttpClient();

X509HostnameVerifier verifier = new X509HostnameVerifier() {
    @Override
    public boolean verify(String hostname, SSLSession session) {
        return true;
    }

    @Override
    public void verify(String arg0, String[] arg1, String[] arg2) throws SSLException {
    }

    @Override
    public void verify(String arg0, X509Certificate arg1) throws SSLException {
    }

    @Override
    public void verify(String arg0, SSLSocket arg1) throws IOException {
    }
};

private static class DefaultTrustManager implements X509TrustManager {

    @Override
    public void checkClientTrusted(java.security.cert.X509Certificate[] arg0, String arg1) throws java.security.cert.CertificateException {
    }

    @Override
    public void checkServerTrusted(java.security.cert.X509Certificate[] arg0, String arg1) throws java.security.cert.CertificateException {
    }

    @Override
    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
        return null;
    }

}

SSLContext sslContext = SSLContext.getInstance("TLSv1");
sslContext.init(null, new TrustManager[] {new DefaultTrustManager()}, new SecureRandom());
SSLContext.setDefault(sslContext);

SSLSocketFactory sf = new SSLSocketFactory(sslContext,verifier);
ClientConnectionManager ccm = httpClient.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", sf, 9002));

HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory());
HttpParams params = new BasicHttpParams();
httpClient = new DefaultHttpClient(ccm, params);

日志中没有太多有用的信息。但是，您为什么不尝试使用不同的 SSL 算法，例如“SSLv2”而不是 TLSv1？
