无法调用 Web 服务

Question

我正在尝试调用一个 Web 服务，为此我使用 POST 发送 xml 数据并且我得到了响应。

生产 Web 服务需要我获得的证书。我已将此证书导入我的密钥库并在我的客户端代码中使用它，但我不断收到超时错误。

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的证书有关？我已将它们导入我的密钥库，但我需要在我的代码中或使用 JBoss（托管应用程序）做其他事情

我也这样做来设置密钥库、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 地址已被列入白名单。我使用 telnet 测试主机，连接超时。如果我 ping 它，我确实收到了数据包。还有什么可能导致无法连接到 Web 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。这是我的问题吗？

Answer 1

我认为这与证书无关。

您是否尝试通过 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。会不会出现白名单不成功的情况？

地址

URL url = new URL(address);

明确包含“httpS”和端口号？
