Jsoup.parse解析HTML字符串，如Jsoup.parse("<html><head><title>Firstparse</title></head>")
Jsoup.connect解析url网站地址，如Jsoup.connect(http://www.baidu.com).get()
可以用httpclient获取网页，再用Jsoup.parse解析页面
String text = getMethod.getResponseBodyAsString();
Document doc = Jsoup.parse(text);
法一：httpclient+Jsoup
1 String dataUrl = "http://hi.mop.com/?"; 2 HttpClient httpClient = new HttpClient(); 3 String cookies = "_ml=371386500452711504675;"; 4 GetMethod getMethod = new GetMethod(dataUrl); 5 // 每次访问需授权的网址时需带上前面的 cookie 作为通行证 6 getMethod.setRequestHeader("cookie", cookies); 7 getMethod.setRequestHeader("Referer", "http://passport.mop.com/"); 8 getMethod.setRequestHeader("User-Agent", "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)"); 9 int statusCodes = httpClient.executeMethod(getMethod); 10 System.out.println(statusCodes); 11 System.out.println("模拟登录成功"); 12 String text = getMethod.getResponseBodyAsString();
法二：Jsoup Connction + Jsoup解析
Connection conn = Jsoup.connect(String url); conn.data("txtBill", key);// 设置关键字查询字段 Document doc = null; doc = conn.timeout(100000).post();//设置请求类型为post型或者get型，超时100000毫秒 results = doc.select(TagName);// 处理返回数据 for (Element result : results){}
