无法使用Java提交HTTPS帖子

Question

我正在编写一些工具（仅用于开发环境），试图自动将消息提交到HTTPPost。我的方法（下面）sendByHTTPSNaive()使用javax.net.ssl.TrustManager的天真实现来接受任何证书。（同样，这是为了进行开发测试。）我正在取回一个未经授权的401代码。下面是我的方法和TLS握手的调试输出。项目网络人员告诉我，我只面对一个xml网关，天真的TrustManager应该通过它，但他们向我保证没有其他身份验证。如果是TLS问题，或者除了xml网关之外还有其他身份验证层，我已经没有办法调试这个问题了？

public String sendByHTTPSNaive(String destinationURI,
                                String msgBodyContent) {
    String result = "no response";
    try {
        URL url = new URL(destinationURI);
        // URLConnection con = url.openConnection();
        HttpsURLConnection con = (HttpsURLConnection) url.openConnection();
        // specify that we will send output and accept input
        con.setDoInput(true);
        con.setDoOutput(true);
        con.setConnectTimeout(20000); // long timeout, but not infinite
        con.setReadTimeout(20000);
        con.setUseCaches(false);
        con.setDefaultUseCaches(false);
        NoopHostnameVerifier HOSTNAME_VERIFIER = new NoopHostnameVerifier();
        TrustManager[] TRUST_MANAGER = { new NaiveTrustManager() };
        if (con instanceof HttpsURLConnection) {
            SSLContext context = SSLContext.getInstance("TLS");
            context.init(new KeyManager[0], TRUST_MANAGER,
                                            new SecureRandom());
            SSLSocketFactory socketFactory = context.getSocketFactory();
            ((HttpsURLConnection) con).setSSLSocketFactory(socketFactory);
            ((HttpsURLConnection) con).setHostnameVerifier(HOSTNAME_VERIFIER);
        }
        // tell the web server what we are sending
        con.setRequestProperty("Content-Type", "text/xml");
        OutputStreamWriter writer = new OutputStreamWriter(
                                        con.getOutputStream());
        writer.write(msgBodyContent);
        writer.flush();
        writer.close();
        // reading the response
        InputStreamReader reader = new InputStreamReader(con.getInputStream());
        StringBuilder buf = new StringBuilder();
        char[] cbuf = new char[2048];
        int num;
        while (-1 != (num = reader.read(cbuf))) {
            buf.append(cbuf, 0, num);
        }
        result = buf.toString();
    } catch (Throwable t) {
        t.printStackTrace(System.out);
    }
    return result;
}

使用标记Djavax.net.debug调试输出=所有

您的TLS工作正常，错误来自HTTP。您需要在请求的同时提供身份验证信息，特别是Authorization标头。响应包含一个"WWW-Authenticate"标头，该标头要求客户端提供凭据。客户端应该使用适当的"Authorization"标头重复请求。
