通过authorizer_refresh_token更新authorizer_access_token(基于Authorizer_appid)

获取（刷新）授权公众号或小程序的接口调用凭据（令牌）

该API用于在授权方令牌（authorizer_access_token）失效时，可用刷新令牌（authorizer_refresh_token）获取新的令牌。请注意，此处token是2小时刷新一次，开发者需要自行进行token的缓存，避免token的获取次数达到每日的限定额度。缓存方法可以参考：http://mp.weixin.qq.com/wiki/2/88b2bf1265a707c031e51f26ca5e6512.html

当换取authorizer_refresh_token后建议保存。

public void updateToken() {
    List list = authorizerDao.findAllAuthorizer();
    for (AuthorizerInfo authorizerInfo :list){
        AuthorizerInfo authorizer = authorizerDao.findAuthorizerByAppId(authorizerInfo.getAuthorizer_appid());
        ConfigInfo config = configDao.findConfigById();
        String token = config.getComponent_access_token();
        String data;
        try {
            Map map = new HashMap<>();
            if (authorizer!=null) {
                map.put("component_appid", COMPONENT_APPID);
                map.put("authorizer_appid", authorizer.getAuthorizer_appid());
                map.put("authorizer_refresh_token", authorizer.getAuthorizer_refresh_token());
                data = HttpRequestor.doPost(

                                + token,
                        GsonUtil.objectToJson(map));
                Map resultData = GsonUtil.parseJsonWithGson(data, Map.class);
                String str = "\"";
                String authorizer_access_token = GsonUtil.objectToJson(resultData.get("authorizer_access_token"))
                        .replace(str, "");
                String authorizer_refresh_token = GsonUtil.objectToJson(resultData.get("authorizer_refresh_token"))
                        .replace(str, "");
                if(authorizer_access_token!=null&&authorizer_refresh_token!=null){
                    authorizer.setAuthorizer_access_token(authorizer_access_token);
                    authorizer.setAuthorizer_refresh_token(authorizer_refresh_token);
                    authorizerDao.updateAuthorizerByAppId(authorizer);
                }else {
                    logger.error(authorizer.getAuthorizer_appid()+"为null.....");
                }
            }
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
