java - 无法调用网络服务

Question

我正在尝试调用一个 Web 服务，我通过 POST 为其发送 xml 数据并收到响应。

生产 Web 服务需要我获得的证书。我已将此证书导入我的 keystore 并在我的客户端代码中使用它，但我一直收到超时错误。

您知道导致此问题的原因吗？

公司已将 ip 地址列入白名单且未在防火墙后运行，此连接问题是否与未正确使用证书有关？我已将它们导入我的 keystore ，但我是否需要在我的代码中或使用 JBoss(托管应用程序)执行其他操作

我也这样做来设置 keystore 、密码、类型等。

System.setProperty("https.protocols", "SSLv3");
    System.setProperty("javax.net.ssl.trustStore", ERPGetProperty.erpGetProperty("pathToKeyStore"));
    System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
    System.setProperty("javax.net.ssl.trustStoreType", "JKS");
    System.setProperty("javax.net.ssl.keyStore", ERPGetProperty.erpGetProperty("pathToKeyStore"));
    System.setProperty("javax.net.ssl.keyStorePassword", "changeit");
    System.setProperty("javax.net.ssl.keyStoreType", "JKS"); 

URL url = new URL(address);
    HttpsURLConnection con  = (HttpsURLConnection) url.openConnection();

    con.setConnectTimeout(10000);
    SSLSocketFactory sslSocketFactory  = (SSLSocketFactory) SSLSocketFactory.getDefault();


    con.setSSLSocketFactory(sslSocketFactory);

    con.setRequestMethod("POST");
    con.setUseCaches(true);
    con.setRequestProperty("Content-type", "text/xml");
    con.setRequestProperty("Host", "pwspg.newcorp.com");
    con.setRequestProperty("Content-Length", Integer.toString(xml.length()));
    con.setRequestProperty("SOAPAction", address);
    con.setDoOutput(true);
    con.setDoInput(true);

    userPass = username + ":" + password;
    byte[] encodeBytes = Base64.encodeBase64(userPass.getBytes());
    String encode = new String(encodeBytes);
    con.setRequestProperty("Authorization", "Basic " + encode);

    out = con.getOutputStream();

    out.write(b);

更新:网络服务所有者再次确认我的 IP 地址已列入白名单。我用telnet测试主机，连接超时。如果我 ping 它，我确实会收到数据包。还有什么可能导致无法连接到网络服务的问题？

有人告诉我这与证书无关，但我似乎找不到问题所在。这是我这边的问题吗？

Answer 1

我认为这与证书无关。

您是否尝试使用 telnet 从您的主机连接到服务的主机？

$ telnet google.com 443
Trying 173.194.44.133...
Connected to google.com.
Escape character is '^]'.

立即连接。

$ telnet pwspg.newcorp.com 443
Trying 38.176.90.103...

永远等待。会不会白名单没有成功？

地址来自

URL url = new URL(address);

明确包含“httpS”和端口号？
