我已经做了这个代码

    DefaultHttpClient httpclient = new DefaultHttpClient();
    CookieStore cookieStore = new BasicCookieStore();
    HttpContext httpContext = new BasicHttpContext();
    httpContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
    HttpGet httpget = new HttpGet("http://localhost:8080/Account/Login");

    HttpResponse response = httpclient.execute(httpget);
    HttpEntity entity = response.getEntity();

    System.out.println("Login form get: " + response.getStatusLine());
    if (entity != null) {
        InputStream is = entity.getContent();
    BufferedReader br = new BufferedReader(new InputStreamReader(is));
    String str ="";
    while ((str = br.readLine()) != null){
        System.out.println(""+str);
    }
        entity.consumeContent();
    }
    System.out.println("Initial set of cookies:");
    List<Cookie> cookies = httpclient.getCookieStore().getCookies();
    if (cookies.isEmpty()) {
        System.out.println("None");
    } else {
        for (int i = 0; i < cookies.size(); i++) {
            System.out.println("- " + cookies.get(i).toString());
        }
    }

    HttpPost httpost = new HttpPost("http://localhost:8080/Account/Login");

    List <NameValuePair> nvps = new ArrayList <NameValuePair>();
    nvps.add(new BasicNameValuePair("Username", "e"));
    nvps.add(new BasicNameValuePair("Password", "password"));

    httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));

    response = httpclient.execute(httpost);
    entity = response.getEntity();
    System.out.println("Double check we've got right page " + EntityUtils.toString(entity));

    System.out.println("Login form get: " + response.getStatusLine());
    if (entity != null) {
        entity.consumeContent();
    }

    System.out.println("Post logon cookies:");
    cookies = httpclient.getCookieStore().getCookies();
    if (cookies.isEmpty()) {
        System.out.println("None");
    } else {
        for (int i = 0; i < cookies.size(); i++) {
            System.out.println("2nd- " + cookies.get(i).toString());
        }
    }

这已经对了吗？？以及如何访问另一个网址？？？让我们说从登录页面之后，我想去 localhost:80/test 页面。帮我解决这个问题。我是这个http客户端的新手。

这是发布请求：

我认为当你这样做时response = httpclient.execute(httpget);，response = httpclient.execute(httpost);你需要包含 HttpContext作为参数以便发送 cookie。请参阅HttpClient.execute(HttpUriRequest request, HttpContext context)。

顺便说一句，如果您列出程序的输出以及您希望它是什么，这也会有所帮助。

另外，我建议使用某种 HTTP 流量检查工具，这样您就可以准确地看到每个请求和响应中发送的内容。例如，如果您使用常规（未加密）HTTP，那么您可以使用Wireshark。还有一些很棒的调试工具可以充当 HTTP(S) 代理，例如Fiddler。
