SOAP客戶端 - ProtocolException：服務器重定向次數過多

Question

我試圖創建SOAP客戶端與服務器進行通信。 使用C＃，一切運行順利，但在Java上我仍然有一些例外。

我們公司落后於代理。 SOAP服務是基本身份驗證的基礎。

小故事：我使用來自wsdl的JAX_WS生成Java生成模式的代碼

/**
 * This class was generated by the JAX-WS RI.
 * JAX-WS RI 2.2.9-b130926.1035
 * Generated source version: 2.2
 */
@WebServiceClient(name = "ServiceWs", targetNamespace = "http://www.web.org/Schema/Klient/Service", wsdlLocation = "https://app.web.org/KlientWS/ServiceWs.wsdl")
public class ServiceWs
        extends Service {
    public ServiceWs(URL wsdlLocation, QName serviceName, WebServiceFeature... features) {
        super(wsdlLocation, serviceName, features);
    }
    ...
}

並通過實現身份驗證和某種cookie：

CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL));
Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
            System.setProperty("java.net.useSystemProxies", "true");

            System.setProperty("proxySet", "true");
            System.setProperty("proxyHost", localProxyHost);
            System.setProperty("proxyPort", localProxyPort);
            System.setProperty("proxyUser", localProxyUser);
            System.setProperty("proxyPassword", localProxyPassword);
            String prot = getRequestingProtocol().toLowerCase();

            // Requesting protocol
            System.setProperty(prot + ".proxyHost", localProxyHost);
            System.setProperty(prot + ".proxyPort", localProxyPort);
            System.setProperty(prot + ".proxyUser", localProxyUser);
            System.setProperty(prot + ".proxyPassword", localProxyPassword);

//          if (getRequestorType() == RequestorType.PROXY) {
//              if (getRequestingHost().toLowerCase().equals(localProxyHost.toLowerCase())) {
//                  if (Integer.parseInt(localProxyPort) == getRequestingPort()) {
//                      // Seems to be OK.
//                      return new PasswordAuthentication(localProxyUser, localProxyPassword.toCharArray());
//                  }
//              }
//          } else
            if (getRequestorType() == RequestorType.SERVER) {
                return new PasswordAuthentication(username, password.toCharArray());
            }
            return null;
        }
    });

並實施客戶端

ServiceWs client;
try {
    URL url = new URL(endpointAddress);
    client = new ServiceWs(url);
} catch (IOException e) {
    client = new ServiceWs();
}

在連接到wsdl文件時，它只是在ProtocolException失敗時有太多的重定向。

更短的版本

我知道身份驗證詳細信息正確且網址正確，因為我可以手動連接到wsdl文件。

Answer 1

問題是，正如@beat在代理設置中建議的那樣。 我沒有正確設置NTLM，因為我們的代理用戶位於不同的域中。

要設置的代碼是System.setProperty("http.auth.ntlm.domain", domain); 設置完成后，一切都按預期開始工作。

在J2SE代理身份驗證中可以看到更多內容。

private void createAuthentication(String localProxyHost, String localProxyPort, 
    String localProxyUser, String localProxyPassword, String domain, 
    String username, String password) {

    if (!prepared) {
        System.setProperty("java.net.useSystemProxies", "true");

        System.setProperty("http.auth.ntlm.domain", domain);
        System.setProperty("proxyHost", localProxyHost);
        System.setProperty("proxyPort", localProxyPort);
        System.setProperty("proxyUser", localProxyUser);
        System.setProperty("proxyPassword", localProxyPassword);

        prepared = true;
        CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL));
        Authenticator.setDefault(new Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password.toCharArray());
            }
        });
    }
}

Answer 2

按照Polostor的要求，我試着寫一個答案。 NTLMv2代理正在對用戶進行身份驗證，如果沒有成功則重定向您。

由於我在不同站點的不同代理有很多問題，我建議使用proxy-vole 。 這將根據平台設置自動設置代理。
