无法从Android上的Jersey clientresponse读取cookie

用于为URI创建Web资源并将过滤器绑定到它以将cookie附加到请求的类

public class TolvenRestClIEnt {        private static ClIEnt clIEnt;        private static final ThreadLocal<String> instance = new ThreadLocal<String>();    static {        ClIEntConfig config = new DefaultClIEntConfig();        clIEnt = ClIEnt.create(config);        clIEnt.setFollowRedirects(true);    }    private ClIEnt getClIEnt() {        return clIEnt;    }    public WebResource getResource(String path){        WebResource webResource = getClIEnt().resource(path);        webResource.addFilter(new ClIEntFilter() {            @OverrIDe            public ClIEntResponse handle(ClIEntRequest clIEntRequest) throws ClIEntHandlerException {                if (instance.get() != null) {                    clIEntRequest.getheaders().putSingle("cookie","SSOcookie=" + instance.get());                }                ClIEntResponse clIEntResponse = getNext().handle(clIEntRequest);                String cookiename = "SSOcookie";                System.out.println("cookies "+clIEntResponse.getcookies());                for (Newcookie newcookie : clIEntResponse.getcookies()) {                    if (cookiename.equals(newcookie.getname())) {                        String extendedSessionID = newcookie.getValue();                                                    instance.set(extendedSessionID);                        break;                    }                }                return clIEntResponse;            }        });         return webResource;    }

然后是一个示例代码来触发webservice调用

RestClIEnt clIEnt = new RestClIEnt();    MultivaluedMap<String,String> formData = new MultivaluedMAPImpl();    formData.add("username","demo");    formData.add("password","1234qwer");    formData.add("realm","tolven");    WebResource webResource = clIEnt.getResource("https://dev.example.com:8443/gatekeeper/rs/authenticate/login");    ClIEntResponse response = webResource.type(MediaType.APPliCATION_FORM_URLENCODED).post(ClIEntResponse.class,formData);    //ClIEntResponse response = webResource.accept("text/HTML").get(ClIEntResponse.class);    System.out.println("Here ....." + response.toString());         webResource = clIEnt.getResource("https://dev.example.com:8443/API/vestibule/accountList");    response = webResource.get(ClIEntResponse.class);    Accounts accounts = response.getEntity(Accounts.class);

从eclipse运行时,此代码工作正常.但是当在androID模拟器中运行时,它无法从客户端响应中读取cookie

我得到以下异常

有没有人试过在AndroID上使用Jersey客户端并看到这个问题？

解决方法 看起来您正在使用Jersey 1.x,并且Newcookie中的JAX-RS运行时委托为空.

如果找不到Jersey meta-inf / services文件,就会发生这种情况.
如果不重新打包meta-inf / services文件,AndroID重新打包过程可能是您的问题的根源,请务必检查.

一种方法是通过提供自己的ServiceIteratorProvider来覆盖服务定位算法.

可以这样使用：

// ...ClIEnt clIEnt = ClIEnt.create();// ...ServiceFinder.setIteratorProvIDer(new YourOwnServiceIteratorProvIDer());// ...
