创建菜单

)存储
至少要保留512
个字符
空间。有效期
为2小时
,需定时刷新,重复获取将导致上次获取的access_token失效3个一级菜单
,每一级菜单最多5个二级菜单
一级菜单最多4个汉字
,二级菜单最多7个汉字
菜单刷新策略:
5分钟之后更新菜单。测试时可以尝试取消关注公众账号后再次关注,则可以看到创建后的效果RestTemplate
配置 (用于远程调用
微信http接口
方法)RestTemplate是Spring提供的用于访问Rest服务的客户端,RestTemplate提供了多种便捷访问远程Http服务的方法,能够大大提高客户端的编写效率。

@Bean
public RestTemplate restTemplate() {

AppID
和AppSecret
获取access_token
access_token是公众号的全局唯一接口调用凭据,公众号调用各接口(下面的创建菜单
、查询菜单
、删除菜单
等)时都需使用access_token!
AccessTokenVO
@Data
@ApiModel(description = "access_token: 公众号的全局唯一接口调用凭据")
public class AccessTokenVO {
@ApiModelProperty(value = "获取到的凭证")
private String access_token;
@ApiModelProperty(value = "凭证有效时间,单位:秒(微信目前暂7200秒,即2小时,过期后需再次获取)")
private int expires_in;
}
public interface IWeixinService {
/**
* 根据AppID和AppSecret获取access_token
*
* @param appId:
* @param appSecret:
* @return: com.zhengqing.demo.modules.weixin.model.AccessTokenVO
*/
AccessTokenVO getAccessToken(String appId, String appSecret);
}
@Slf4j
@Service
public class WeixinServiceImpl implements IWeixinService {
@Autowired
private RestTemplate restTemplate;
@Override
public AccessTokenVO getAccessToken(String appId, String appSecret) {
AccessTokenVO accessTokenVO = restTemplate.getForObject(Constants.GET_ACCESS_TOKEN_URL.replace("APPID", appId).replace("APPSECRET", appSecret), AccessTokenVO.class);
return accessTokenVO;
}
}
click
和view
请求示例{
"button":[
{
"type":"click",
"name":"今日歌曲",
"key":"V1001_TODAY_MUSIC"
},
{
"name":"菜单",
"sub_button":[
{
"type":"view",
"name":"搜索",
"url":"http://www.soso.com/"
},
{
"type":"miniprogram",
"name":"wxa",

"appid":"wx286b93c14bbf93aa",
"pagepath":"pages/lunar/index"
},
{
"type":"click",
"name":"赞一下我们",
"key":"V1001_GOOD"
}]
}]
}

创建自定义菜单
、查询菜单
、删除菜单
注:这里小编将获取到的access_token
写死到常量 Constants.ACCESS_TOKEN
中做测试,实际项目中可将access_token
保存到缓存中,每隔快到2个小时的时候去重新获取一次刷新缓存数据 ~
