使用httpfox（firefox的一个插件）查看登录时浏览器发送的表单数据
最后登录代码如下，下面使用到了Jsoup提取html的标签信息
public boolean Login(String username , String password){String getgsid = null;String content = Get(LoginUrl);if(content==null) return false;Document doc = Jsoup.parse(content); Element form=null , pwnd=null , vk=null;String rand=null , spwnd=null , svk=null;form = doc.select("form[method=post]").first();pwnd = doc.select("input[type=password]").first();vk = doc.select("input[name=vk]").first();if(form==null || pwnd==null || vk==null) return false;rand = form.attr("action");spwnd = pwnd.attr("name");svk = vk.attr("value");if(rand==null || spwnd==null || svk==null) return false;try {String url = "/prog/wapsite/sso/"+rand;HttpPost post = new HttpPost(url);post.setHeader("User-Agent","Mozilla/5.0 (X11; Linux i686; rv:5.0) Gecko/0101 Firefox/5.0");post.setHeader("Referer", "/");post.setHeader("Content-Type", "application/x-www-form-urlencoded");List<NameValuePair> qparams = new ArrayList<NameValuePair>();qparams.add(new BasicNameValuePair("mobile", username));qparams.add(new BasicNameValuePair(spwnd, password));qparams.add(new BasicNameValuePair("remember", "on"));qparams.add(new BasicNameValuePair("backURL", "/dpool/ttt/home.php"));qparams.add(new BasicNameValuePair("backTitle", "新浪微博"));qparams.add(new BasicNameValuePair("vk", svk));qparams.add(new BasicNameValuePair("submit", "登录"));UrlEncodedFormEntity params = new UrlEncodedFormEntity(qparams, "UTF-8");post.setEntity(params);httpclient.execute(post);post.abort();List<Cookie> cookies = httpclient.getCookieStore().getCookies();if(cookies.size()!=0) getgsid=cookies.get(0).getValue();else getgsid=null;gsid = getgsid;} catch (ClientProtocolException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch(Exception e){// TODO Auto-generated catch blocke.printStackTrace();} finally{if(gsid==null) return false;else return true;}}
