java - 使用 Java org.apache.http.client 获取重定向 url

Question

我需要帮助来弄清楚在我向服务器发帖后如何获得重定向。首先，我需要执行 get 从服务器获取一些 cookie。然后我使用 cookie 和其他参数执行一个帖子。然后服务器以 302 重定向响应。我如何获取该重定向的网址？

代码如下:

HttpGet get = new HttpGet(urlOne);

try {
    //Creating a local instance of cookie store.
    CookieStore cookieJar = new BasicCookieStore();

    // Creating a local HTTP context
    HttpContext localContext = new BasicHttpContext();

    // Bind custom cookie store to the local context
    localContext.setAttribute(ClientContext.COOKIE_STORE, cookieJar);

    HttpResponse response = httpClient.execute(get, localContext);
    HttpEntity entity = response.getEntity();

    System.out.println("------------------GET----------------------");
    System.out.println(response.getStatusLine());
    if (entity != null) {
        System.out.println("Response content length: " + entity.getContentLength());
    }

    // Print out cookies obtained from server
    List<Cookie> cookies = cookieJar.getCookies();
    for (int i = 0; i < cookies.size(); i++) {
        System.out.println("Local cookie: " + cookies.get(i));
    }        

    if (entity != null) {
       entity.consumeContent();
    }
    System.out.println("------------------GET-END---------------------");

    // Create a new post
    HttpPost post = new HttpPost(urlTwo);
    post.setHeader("Content-Type", "application/x-www-form-urlencoded");

    // Add params
    HttpParams params = new BasicHttpParams();
    params.setParameter("action", "search");
    params.setParameter("word", "hello");

    post.setParams(params);

    //Execute
    HttpResponse response2 = httpClient.execute(post, localContext);
