没有设置cookie，下面是代码。
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httpPostRequest = new HttpPost(URL);
CookieStore cookieStore = new BasicCookieStore();
BasicClientCookie cookie = new BasicClientCookie("Name", "value");
cookieStore.addCookie(cookie);
HttpContext localContext = new BasicHttpContext();
localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
httpPostRequest.setEntity(fileentity);
HttpResponse response = (HttpResponse) httpclient.execute(httpPostRequest,localContext);
也尝试了
httpclient.setCookieStore(cookieStore);
但没有任何作用。
