1.首先创建一个工具类

public class ConTools {    private HttpURLConnection connection;    /**     * TangRen 2016-4-9 下午3:11:28     */    public HttpURLConnection ConTools(String urlString) {        try {            URL url = new URL(urlString);            connection = (HttpURLConnection) url.openConnection();            connection.setDoOutput(true);            connection.setDoInput(true);            connection.setRequestMethod("POST");            connection.setConnectTimeout(5000);            connection.setReadTimeout(5000);            connection.setInstanceFollowRedirects(true);            connection.setRequestProperty("Content-Type",                    "application/json; encoding=UTF-8");            connection.connect();        } catch (MalformedURLException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (ProtocolException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }catch (Exception e) {            // TODO: handle exception            e.printStackTrace();        }        return connection;    }}

Read工具类

public class ReadTools {    /**     * TangRen 2016-4-9 下午3:22:23     */    private BufferedReader reader;    private StringBuffer sb;    public StringBuffer ReadTools(HttpURLConnection connection) {        try {            reader = new BufferedReader(new InputStreamReader(                    connection.getInputStream()));            String line;            sb = new StringBuffer("");            while ((line = reader.readLine()) != null) {                line = new String(line.getBytes(), "UTF-8");                sb.append(line);            }            reader.close();        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        return sb;    }}

接下来就是申请TOKEN

public class ApplyToken {    /**     * @param args     * @author TangRen     * @date 2016-4-14 上午9:41:19     */    private static ReadTools read;    private static HttpURLConnection connection;    static StringBuffer readTools = null;    public static void main(String[] args) {        // TODO Auto-generated method stub        ApplyToken();    }    public static String  ApplyToken() {        // TODO Auto-generated constructor stub        try {            URL url = new URL(AppURL.url_applytoken);            connection = (HttpURLConnection) url.openConnection();            connection.setDoOutput(true);            connection.setDoInput(true);            connection.setRequestMethod("GET");            connection.setConnectTimeout(5000);            connection.setReadTimeout(5000);            connection.setInstanceFollowRedirects(true);            connection.setRequestProperty("Content-Type",                    "application/json; encoding=UTF-8");            connection.connect();            DataOutputStream outputStream=new DataOutputStream(connection.getOutputStream());            BufferedWriter writer=new BufferedWriter(new OutputStreamWriter(outputStream,"UTF-8"));            writer.flush();            writer.close();            read = new ReadTools();            readTools = read.ReadTools(connection);            System.out.println(readTools);            // 断开连接            connection.disconnect();        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        return readTools.toString();    }}
