问题描述

下面首先要进行HTTP请求到URL，然后想发布一些数据网址我使用 JSOUP 这是由user.here输入。可以任何一个建议一些简单的way.Felt难以Ktutorial.followed 这的任何那么建议任何例子或者容易tutorial.Thanks提前

下面添加code

 字符串strResp = NULL;
            HttpClient的客户端=新DefaultHttpClient（）;
            HttpPost后=新HttpPost（
                    http://motinfo.direct.gov.uk/internet/jsp/ECHID-Internet-History-Request.jsp）;            清单＆LT;＆的NameValuePair GT; namevaluepairs中=新的ArrayList＆LT;＆的NameValuePair GT;（2）;
            nameValuePairs.add（新BasicNameValuePair（
                    从号牌车辆登记号码，DU06BFZ））;
            namevaluepairs中
                    。新增（新BasicNameValuePair（
                            MOT测试人数从-VT20测试证书，VT30拒绝证书，
                            435294573022））;            / *
             * nameValuePairs.add（新BasicNameValuePair（MOT测试号，
             *000000））;
             * /            尝试{
                loadingProgressBar =（进度）findViewById（R.id.progressBar1）;
                loadingProgressBar.setVisibility（View.VISIBLE）;
                post.setEntity（新UrlEn codedFormEntity（namevaluepairs中））;
                HTT presponse响应= client.execute（岗位）;
                strResp = EntityUtils.toString（response.getEntity（））;
                文献文件= Jsoup.parse（strResp）;
                元件连结= document.select（A）的第一（）;
                。字符串文本= document.body的（）文本（）;
                }赶上（UnsupportedEncodingException五）{
                // TODO自动生成catch块
                e.printStackTrace（）;
            }赶上（ClientProtocolException E）{
                // TODO自动生成catch块
                e.printStackTrace（）;
            }赶上（IOException异常五）{
                // TODO自动生成catch块
                e.printStackTrace（）;
            }
            返回strResp;
        }
 

解决方案

使用 JSOUP ，你可以做发表作为如下：

  //需要http协议
  文档的DOC = Jsoup.connect（http://www.something.com）// YOUR_URL
  。数据（key_one，value_one）
  。数据（key_two，value_two）
  //并在POST请求传递等隐藏字段。
  //我们推荐指定Jsoup一个的userAgent，以避免HTTP 403错误消息。
  .userAgent（Mozilla的）
  。员额（）;
   的System.out.println（DOC）; //将打印页面的HTML源，你要连接。
 

Here first want to make http request to url and then want to post some data to url which is entered by user.here i am using JSOUP. Could any one suggest some easy way.Felt difficult with Ktutorial.followed this any one suggest any example or easy tutorial.Thanks in advance

adding code here

String strResp = null;
            HttpClient client = new DefaultHttpClient();
            HttpPost post = new HttpPost(
                    "http://motinfo.direct.gov.uk/internet/jsp/ECHID-Internet-History-Request.jsp");

            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair(
                    "Vehicle registration mark from number plate", "DU06BFZ"));
            nameValuePairs
                    .add(new BasicNameValuePair(
                            " MOT test number from-VT20 test certificate-VT30 refusal certificate ",
                            "435294573022"));

            /*
             * nameValuePairs.add(new BasicNameValuePair("MOT test number",
             * "000000"));
             */

            try {
                loadingProgressBar = (ProgressBar) findViewById(R.id.progressBar1);
                loadingProgressBar.setVisibility(View.VISIBLE);
                post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                HttpResponse response = client.execute(post);
                strResp = EntityUtils.toString(response.getEntity());
                Document document = Jsoup.parse(strResp);
                Element link = document.select("a").first();
                String text = document.body().text();       
                } catch (UnsupportedEncodingException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            return strResp;
        }

解决方案

Using JSOUP you can do Post as follows:

// need http protocol
  Document doc = Jsoup.connect("http://www.something.com") // your_url
  .data("key_one", "value_one")
  .data("key_two", "value_two")
  // and other hidden fields which are being passed in post request.
  //It’s recommended to specify a "userAgent" in Jsoup, to avoid HTTP 403 error messages.
  .userAgent("Mozilla")  
  .post();
   System.out.println(doc); // will print html source of page ,you are trying to connect.
