已经解决。 代商家获取小程序详情接口，在这分享一下：

@RequestMapping(value = {"/qurey/minin/info"}, method = RequestMethod.POST)
public JSONObject queryMiniNameStatus(@RequestBody JSONObject body) {

    try {

        return wechatPlatformService.queryMiniInfo(body);

    } catch (Exception e) {
        log.error(StackTool.error(e, 100));
        return new JSONObject().fluentPut("resCode", Constants.KEY_OP_FAIL).fluentPut("resMsg", e.getMessage());
    }


}

/**
 * 查询小程序名称设置状态
 *
 * @param body
 * @return
 * @throws Exception
 *
 
 */
public JSONObject queryMiniInfo(JSONObject body) throws Exception {

    String component_appid = body.getString("component_appid");

    String authorizer_appid = body.getString("authorizer_appid");

    PlatformGrant grant = getApiToken(component_appid, authorizer_appid);

    HttpHeaders headers = new HttpHeaders();
    MediaType type = MediaType.parseMediaType("application/json; charset=utf-8");
    headers.setContentType(type);
    headers.add("Accept", MediaType.APPLICATION_XML.toString());

    restTemplate.getMessageConverters().set(1, new StringHttpMessageConverter(StandardCharsets.UTF_8));
    String url = "https://api.weixin.qq.com/cgi-bin/account/getaccountbasicinfo?access_token=" + grant.getAuthorizer_access_token();
    body.remove("component_appid");
    body.remove("authorizer_appid");

    HttpEntity<JSONObject> formEntity = new HttpEntity<JSONObject>(body, headers);
    JSONObject res = restTemplate.postForObject(url, formEntity, JSONObject.class);
    log.info("---->小程序基本信息查询 res {}", res);
    Integer status = res.getInteger("errcode");

    JSONObject  head_image_info = res.getJSONObject("head_image_info");
    if (head_image_info != null) {

       String head_image_url = head_image_info.getString("head_image_url");

        if ( StringUtils.isEmpty(grant.getHead_image_url()) ) {

            grant.setHead_image_url(head_image_url);

            platformGrantRepository.save(grant);
            log.info("--->更新小程序的图像<---- {}",head_image_url);
        }

    }


    JSONObject result = new JSONObject();
    if (status != null && status.intValue() == 0) {
        result.put("resCode", "0");
        result.put("resMsg", "OK");
        result.put("result", res);


    } else {
        result.put("resCode", Constants.KEY_OP_FAIL);
        result.put("resMsg", res.getString("errmsg"));

    }
    return result;


}


其中，获取第三方授权的 access_token 放在缓存中，过期了才向微信获取，并且持久化到表 PlatformGrant 中。以下是源码参照：

/**
 * 获取/刷新接口调用令牌
 * @param component_appid: 第三方平台appid
 * @param grant：
 * @return
 */

public PlatformGrant getApiToken(String component_appid, String authorizer_appid) throws Exception {

    String component_access_token =  getComponentAccessToken(component_appid);
    PlatformGrant grant = getPlarformGrant(component_appid,authorizer_appid) ;
    if (grant == null)  {

        throw new RuntimeException("平台未保存用户的授权信息");
    }

    // 先不着急重新调用接口获取
    if ( grant.getExpires_in() != null && grant.getUpdate_time() != null) {
        if (DateUtil.valid(grant.getUpdate_time(), grant.getExpires_in())){

            // 没有过期
            return grant;

        }
    }



    HttpHeaders headers = new HttpHeaders();
    MediaType type = MediaType.parseMediaType("application/json; charset=utf-8");
    headers.setContentType(type);
    headers.add("Accept", MediaType.APPLICATION_JSON.toString());
    JSONObject reqBody = new JSONObject();
    reqBody.put("component_access_token", component_access_token);
    reqBody.put("component_appid", component_appid);
    reqBody.put("authorizer_appid", authorizer_appid);
    reqBody.put("authorizer_refresh_token", grant.getAuthorizer_refresh_token());

    HttpEntity<JSONObject> formEntity = new HttpEntity<JSONObject>(reqBody, headers);
    restTemplate.getMessageConverters().set(1, new StringHttpMessageConverter(StandardCharsets.UTF_8));
    String url = "https://api.weixin.qq.com/cgi-bin/component/api_authorizer_token?component_access_token="+component_access_token;
    JSONObject   json  = restTemplate.postForObject(url, formEntity, JSONObject.class);
    log.info(">>>授权码获取授权信息 返回：{}",json);
    if ( json.getIntValue("errcode") != 0 )  {

        // {"errcode":61023,"errmsg":"refresh_token is invalid rid: 6228c03e-19027c0c-7a98021d"}
        if (json.getString("errmsg").indexOf("refresh_token is invalid") != -1) { //需要从数据库取

        }
    }

    String authorizer_access_token = json.getString("authorizer_access_token");
    String authorizer_refresh_token = json.getString("authorizer_refresh_token");
    int expires_in = json.getIntValue("expires_in");

    grant = new  PlatformGrant();
    grant.setComponent_appid(component_appid);
    grant.setAuthorizer_access_token(authorizer_access_token);
    grant.setAuthorizer_appid(authorizer_appid);
    grant.setAuthorizer_refresh_token(authorizer_refresh_token);
    grant.setExpires_in(expires_in);
    return savePlatformGrant(grant);



}

先从缓存中获取商家授权acess_token，获取不到或过期了再实时查询

/**
 * 获取平台 component_access_token 有效期2h
 * @return
 */
public String getComponentAccessToken(String appId)  {


    WechatToken token = null;
    String key= RedisTool.getComponentAccessTokenKey(appId);
    //先从缓存中取：
    try {

        token =( WechatToken)redisTemplate.opsForValue().get(key);
        if( null !=  token) {

            log.info("---成功获取ComponetAccessToken:{}",token.toString());

            return token.getToken();
        }


    }catch(Exception e) {
        log.warn("----->getComponentAccessToken异常<-----");
        log.error(StackTool.error(e,100));

    }


    log.info("--缓存中未获取到ComponetAccessToken 即时查询接口 ----" );
    String url = "https://api.weixin.qq.com/cgi-bin/component/api_component_token";
    JSONObject reqBody = new JSONObject();
    String appSecret = null;

    if (appId.equals(wXBizMsgCrypt.getAppId())) {

        appSecret = wXBizMsgCrypt.getAppSecret();
    }else{
        MuchApiWechat api = muchApiWechatRepository.findMuchApiWechat(appId);
        if (api == null) {
            throw new RuntimeException("平台没有配置第三方小程序"); // wxc24950555e542854
        }
        appSecret = api.getAppsecret();

    }
    reqBody.put("component_appid", appId);
    reqBody.put("component_appsecret", appSecret);

    String component_verify_ticket = getComponentVerifyTicket(appId);

    if (StringUtils.isEmpty(component_verify_ticket)) {

        throw new RuntimeException("component_verify_ticket为空，请联系平台技术人员");

    }
    reqBody.put("component_verify_ticket", component_verify_ticket);
    HttpHeaders headers = new HttpHeaders();
    MediaType type = MediaType.parseMediaType("application/json; charset=utf-8");
    headers.setContentType(type);
    headers.add("Accept", MediaType.APPLICATION_XML.toString());
    HttpEntity<JSONObject> formEntity = new HttpEntity<JSONObject>(reqBody, headers);
    restTemplate.getMessageConverters().set(1, new StringHttpMessageConverter(StandardCharsets.UTF_8));
    JSONObject result = restTemplate.postForObject(url, formEntity, JSONObject.class);
    log.info(">>>获取令牌返回： result="+result);

    //  result={"errcode":61004,"errmsg":"access clientip is not registered requestIP: XX rid: 63a0f0bf-21116836-466eea46"}
    Integer errcode = result.getInteger("errcode") ;

    if (errcode != null && errcode.intValue() != 0) {

             throw new RuntimeException(result.getString("errmsg"));
    }

    String component_access_token = result.getString("component_access_token");

    if (!StringUtils.isEmpty(component_access_token)) {
        Long now=System.currentTimeMillis()/1000;
        token  = new WechatToken(now,component_access_token );
        try{
            redisTemplate.opsForValue().set(key, token , 7200, TimeUnit.SECONDS);
        }catch(Exception e){
            log.warn("redis component_access_token 异常");
        }
    }

    log.info("---->第三方平台 access_token:{}", component_access_token);

    return component_access_token;

}

最后， 通过第三方平台来管理商家微信小程序，也可以由商家来自助管理。如：设置小程序图像、小程序介绍等信息。贴一张图片大家看看效果。微信的接口调用正确了还是非常稳定的。 之所以调用出错是没有使用商家的授权 authorizer_access_token
