android 中使用jwt token(json web token)--java

http://blog.csdn.net/mingzhnglei/article/details/51119836

下面贴上自己项目中的一个小小的example

import com.nimbusds.jose.JOSEException;
import com.nimbusds.jose.JWSAlgorithm;
import com.nimbusds.jose.JWSHeader;
import com.nimbusds.jose.JWSObject;
import com.nimbusds.jose.JWSSigner;
import com.nimbusds.jose.Payload;
import com.nimbusds.jose.crypto.MACSigner;

import net.minidev.json.JSONObject;

public class Example {

    static String DUOSHUO_SHORTNAME = "test";
    static String DUOSHUO_SECRET = "3d990d2276917dfac04467df11fff26d";

    public static void main(String [] args){

        JSONObject userInfo = new JSONObject();

        userInfo.put("short_name", DUOSHUO_SHORTNAME);//必须项
        userInfo.put("user_key", "1");//必须项
        userInfo.put("name", "网站用户A");//可选项

        Payload payload = new Payload(userInfo);

        JWSHeader header = new JWSHeader(JWSAlgorithm.HS256);
        header.setContentType("jwt");


        // Create JWS object
        JWSObject jwsObject = new JWSObject(header, payload);

        // Create HMAC signer
        JWSSigner signer = new MACSigner(DUOSHUO_SECRET.getBytes());

        try {
            jwsObject.sign(signer);
        } catch (JOSEException e) {
            System.err.println("Couldn't sign JWS object: " + e.getMessage());
            return;
        }
        // Serialise JWS object to compact format
        String token = jwsObject.serialize();
        System.out.println("Serialised JWS object: " + token);
        //示例输出结果为eyJhbGciOiJIUzI1NiIsImN0eSI6Imp3dCJ9.eyJ1c2VyX2tleSI6IjEiLCJuYW1lIjoi572R56uZ55So5oi3QSIsInNob3J0X25hbWUiOiJ0ZXN0In0.NXKDXwXThzFkyfl_k_-p6mfM5cpOFppvfdIjrjEq14I
