[转载]Android 使用三种方式获取网页（通过Post，Get进行表单的提交）

    // 直接获取信息
    void DirectInfo() throws IOException {

        URL url = new URL(SRC);

        HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();

        InputStreamReader inStreamReader = new InputStreamReader(httpConn
                .getInputStream());

        BufferedReader bufReader = new BufferedReader(inStreamReader);

        String line = "";
        String Date = "OK";
        while ((line = bufReader.readLine()) != null) {
            Date += line + "\n";
        }

        edit1.setText(Date);

    }

    // get方式获取信息
    void getInfo() throws IOException {
        // 将上面使用的方法直接修改一下即可。

        URL url = new URL(SRC+"/default.aspx?NAME="
                + URLEncoder.encode("abc", "utf-8"));
        HttpURLConnection httpconn = (HttpURLConnection) url.openConnection();

        InputStreamReader inputReader = new InputStreamReader(httpconn
                .getInputStream());

        BufferedReader bufReader = new BufferedReader(inputReader);

        String line = "";
        String Date = "";

        while ((line = bufReader.readLine()) != null) {
            Date += line;
        }

        edit1.setText(Date);

    }

    // Post方式获取信息
    void postInfo() throws MalformedURLException, IOException {
        // Post 方法比Get方法需要设置的参数更多

        HttpURLConnection httpconn = (HttpURLConnection) new URL(SRC)
                .openConnection();
        // post 方式，输入输出需要设置为true
        httpconn.setDoInput(true);
        httpconn.setDoOutput(true);
        httpconn.setRequestMethod("POST"); // 设置为Post方式，默认为get方式
        httpconn.setUseCaches(false); // 不使用缓存
        httpconn.setInstanceFollowRedirects(true); // 重定向
        httpconn.setRequestProperty("Content-type",
                "Application/x-www-form-urlencoded"); // 设置连接 的Content-type类型为：
        // application/x-www-form-urlencoded
        httpconn.connect();     //连接
        
        DataOutputStream out = new DataOutputStream(httpconn.getOutputStream());  //声明数据写入流
        
        String content = "NAME="+URLEncoder.encode("fly_binbin", "gb2312");
        
        out.writeBytes(content);
        
        out.flush();
        out.close();

        BufferedReader reader = new BufferedReader(new InputStreamReader(httpconn.getInputStream()));
        
        String line = "";
        String resultDate = "";
        while((line=reader.readLine())!=null)
        {
            resultDate += line;
        }
        edit1.setText(resultDate);

    }
