Question

我有这个代码，编译并运行没有问题：

            DefaultHttpClient httpclient = new DefaultHttpClient();

            HttpGet httpget = new HttpGet("http://www.cashialize.com/wp-login.php");

            HttpResponse response = httpclient.execute(httpget);

                    CookieStore cookieStore = new BasicCookieStore();

            // Bind custom cookie store to the local context
            httpclient.setCookieStore(cookieStore);
            CookieSpecFactory csf = new CookieSpecFactory() {

                        }

            HttpGet httpGet = new HttpGet("http://www.articlepub.com/wp-admin/profile.php");
            response = httpclient.execute(httpGet);
            entity = response.getEntity();

            System.out.println("Post get cookies:");

            }


            httpclient.getConnectionManager().shutdown();

        } catch (Exception e) {
            System.out.println(e);

        }

    }

}

问题是我无法让用户登录。我很确定我在cookies设置中遗漏了一些内容，但我无法发现它，因为这是我第一次登录尝试。

控制台输出似乎也很好 - 唯一的问题是我无法发现cookie。这是：

Login form get: HTTP/1.1 200 OK
Initial set of cookies:
None
Login form get: HTTP/1.1 302 Found
Post logon cookies:
None
Login form get: HTTP/1.1 200 OK
Post get cookies:
None

请帮我解决这个噩梦吧！我很确定我错过了一些非常小的东西，但我无法弄明白。

我认为您需要在执行之前在客户端上配置cookie存储。您也可以使用cookie管理器配置HttpContext。
