[英]SOAP client - ProtocolException: Server redirected too many times
I tried to create SOAP client to communicate with server. 我试图创建SOAP客户端与服务器进行通信。 Everything runs smoothly with C# but on Java I still get some exceptions.
使用C#,一切运行顺利,但在Java上我仍然有一些例外。
Our company is behind proxy. 我们公司落后于代理。 SOAP service is behind basic authentication.
SOAP服务是基本身份验证的基础。
Small behind story: I generated code with Java generate schema with JAX_WS from wsdl 小故事:我使用来自wsdl的JAX_WS生成Java生成模式的代码
/**
* 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);
}
...
}
And with implementation authentication and cookies of some kind: 并通过实现身份验证和某种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;
}
});
And implementation of client 并实施客户端
ServiceWs client;
try {
URL url = new URL(endpointAddress);
client = new ServiceWs(url);
} catch (IOException e) {
client = new ServiceWs();
}
And it just fails there with ProtocolException with too many redirections while connecting to wsdl file. 在连接到wsdl文件时,它只是在ProtocolException失败时有太多的重定向。

I know authentication details are correct and web address is correct, as I can connect to the wsdl file manually. 我知道身份验证详细信息正确且网址正确,因为我可以手动连接到wsdl文件。
The problem was, as @beat suggested in the proxy settings. 问题是,正如@beat在代理设置中建议的那样。 I have not set the NTLM properly, as our proxy user is in different domain.
我没有正确设置NTLM,因为我们的代理用户位于不同的域中。
The code to be set was System.setProperty("http.auth.ntlm.domain", domain);
要设置的代码是
System.setProperty("http.auth.ntlm.domain", domain);
and after setting this everything started to work as intended. 设置完成后,一切都按预期开始工作。
More to be seen in J2SE Proxy Authentication . 在J2SE代理身份验证中可以看到更多内容。
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());
}
});
}
}
As requested by Polostor, I try to write an answer. 按照Polostor的要求,我试着写一个答案。 NTLMv2 Proxies are authenticating the user, and if not sucessful redirect you.
NTLMv2代理正在对用户进行身份验证,如果没有成功则重定向您。
As I had a lot of issues with different proxies at different sites, I do recommend using proxy-vole . 由于我在不同站点的不同代理有很多问题,我建议使用proxy-vole 。 This will do an automatic setup of your proxies based on the platform settings.
这将根据平台设置自动设置代理。
