微信&java 开发3 菜单接口

初始化菜单首先要获取accesstoken，关于accesstoken的获取和缓存在下面和后面的文章中介绍

public class WeixinTest {public static void main(String[] args) {try {AccessToken token = WeixinUtil.getAccessToken();System.out.println("票据"+token.getToken());System.out.println("有效时间"+token.getExpiresIn());String menu = JSONObject.fromObject(WeixinUtil.initMenu()).toString();int result = WeixinUtil.createMenu(token.getToken(), menu);if(0 == result) {System.out.println("成功!");} else {System.out.println("失败!");}} catch (Exception e) {e.printStackTrace();}}}

看一下WeiXinUtil.getAccessToken()

/** * 获取accessToken *  * @return * @throws ParseException * @throws IOException */public static AccessToken getAccessToken() throws ParseException,IOException {AccessToken token = new AccessToken();String url = ACCESS_TOKEN_URL.replace("APPID", WeiXinPropUtil.APPID).replace("APPSECRET", WeiXinPropUtil.APPSECRET);JSONObject jsonObject = doGetStr(url);if (jsonObject != null) {token.setToken(jsonObject.getString("access_token"));token.setExpiresIn(jsonObject.getInt("expires_in"));}return token;}

url: private static final String ACCESS_TOKEN_URL = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET";

这里 APPID APPSECRET我是存到properties中，然后读取这样再有变化时只要修改properties文件即可

public class WeiXinPropUtil {public static String APPID = "";public static String APPSECRET = "";public static String WebDomain = "";private static Properties props = new Properties();private static InputStream in;static {try {in = WeixinUtil.class.getResourceAsStream("/properties/web.properties");props.load(in);} catch (IOException e) {e.printStackTrace();}if (!props.isEmpty()) {WebDomain = props.getProperty("webDomain").toString();APPID = props.getProperty("APPID").toString();APPSECRET = props.getProperty("APPSECRET").toString();}}private WeiXinPropUtil(){}}

/** * get请求 *  * @param url * @return * @throws ParseException * @throws IOException */public static JSONObject doGetStr(String url) throws ParseException,IOException {DefaultHttpClient client = new DefaultHttpClient();HttpGet httpGet = new HttpGet(url);JSONObject jsonObject = null;HttpResponse httpResponse = client.execute(httpGet);HttpEntity entity = httpResponse.getEntity();if (entity != null) {String result = EntityUtils.toString(entity, "UTF-8");jsonObject = JSONObject.fromObject(result);}return jsonObject;}
