使用httpclient在android上保持cookie会话

Question

您好我正在使用HttpClient的单独实例和HttpResponce实例进行多次http调用并从服务器获取响应。问题是我无法存储cookie，每次登录后发出请求都会返回“身份验证错误：无法响应任何这些挑战”。我如何为我的用例存储cookie？这是代码：

public class MyHttpClient {

private DefaultHttpClient httpClient = new DefaultHttpClient();

    private CookieStore cookieStore = new BasicCookieStore();
    BasicHttpContext localContext = new BasicHttpContext();


 public MyHttpResponse get(String url) throws IOException{
          cookieStore = httpClient.getCookieStore();
          localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
      HttpGet httpGet = new HttpGet(url);
      return new MyHttpResponse(httpClient.execute(httpGet, localContext));

}

public MyhttpResponse post(String url, Arraylist<String> params ) throws IOException{
     cookieStore = httpClient.getCookieStore();
     localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
     HttpPost httpPost = new HttpPost(url);
     /* put params */
 return new MyHttpResponse(httpClient.execute(httpPost, localContext));

}

MyResponse获得回复正文：

   if(response.getEntity() != null){
        InputStream lineStream = response.getEntity().getContent();

Answer 1

试试这个：

CookieSyncManager cookieSyncManager = CookieSyncManager.createInstance(context);
CookieManager cookieManager = CookieManager.getInstance(); 
cookieManager.setAcceptCookie(true);
cookieManager.setCookie(url,value);
cookieSyncManager.sync();

在将我的httpClient设为Singleton后，我开始工作了。我不知道这是否是在整个应用程序中保持会话的最佳解决方案，但它确实有效。
