如何使用Ajax從網頁上使用httpclient 4.3.x獲取信息

Question

例如，從https://play.google.com/store/apps獲取全部內容

我發現它發布了數據：

“開始= 15＆num = 5＆numChildren = 10pagTok = CA8QDxjh2ND3psHQ4pcB％3AS％3AANO1ljLBy5U＆ipf = 1＆xhr = 1”

顯示下一個瀏覽器頁面，然后我用

  HttpPost httpPost = new HttpPost("https://play.google.com/store/apps");
  List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("start","15"));
    params.add(new BasicNameValuePair("num","5"));
    params.add(new BasicNameValuePair("numChildren","10"));
    params.add(new BasicNameValuePair("pagTok","CA8QDxjh2ND3psHQ4pcB"));
    params.add(new BasicNameValuePair("ipf","1"));
    params.add(new BasicNameValuePair("xhr","1"));

    httpPost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));
    CloseableHttpResponse response = getSSLHttpClient().execute(httpPost);
    HttpEntity entity = response.getEntity();
    try {
        if(entity != null) {
            return EntityUtils.toString(entity);
        }
    } finally {
        EntityUtils.consume(entity);
        response.close();
    }

但是最后我無法從googleplay獲取網絡文檔，結果是一些javascript，怎么了？

Apache HTTP Client用於獲取頁面內容。 如果您需要在此頁面上執行javascript，則可以使用HtmlUnit 。 這是一個例子
