java springboot调用微信公众平台（公众号）api，主要针对发布图文案例
- 微信公众平台官网地址
- 1.公众号配置服务器地址，微信验证成功后，配置白名单
- 2.application.yml配置微信的相关信息
- 3.接口和代码
- contoller类
- service接口
- serviceImpl实现类
- 工具类
- 实体model
- 4.说明：
微信公众平台官网地址
登录地址：https://mp.weixin.qq.com/ api地址：https://developers.weixin.qq.com/doc/offiaccount/Getting_Started/Overview.html
1.公众号配置服务器地址，微信验证成功后，配置白名单
注：微信验证服务器地址需要写个接口接收数据进行验证，成功后才能通过，接口已经在下面代码里有了
2.application.yml配置微信的相关信息
3.接口和代码
contoller类

}吐槽： 公众号的api接口文档写的简直依托答辩，返回值错误直接英译汉，而没有说明为什么发生，该怎么解决
4.说明：
1. redisService个人用自己或公司封装，或者自己去写，微信的accessToken两小时过期，具体请看公众号api
2. httpUtils里面上传附件素材含有/t /n 等不要删，删了调用接口就报错，官方api上也没说没写，个人找资料测出来的
3. 上面这些只是基础接口，如果想要自己发布内容，要自己调取相关接口
4. 公众号答辩接口对图片识别很敏感，例如网上找个webp（不支持）的格式，下载本地改名改格式为jpg，这种图微信度不支持会报错
5. 如果api调用发布一个推送(富文本中带图文)，我自己写的流程是：
(1). 获取accessToken
(2). 上传永久素材（封面图）。获取封面图media_id
(3). 上传草稿。因为公众号中不识别外部图片，所以content中内图片等附件url要全部替换成腾讯的；步骤是要先获取到富文本中内容，截取富文本中所有图片附件url,然后上传获取到这些图片腾讯返回的url,替换原本的每个图片ur
(4). 草稿发布
(5). 群发消息
6. 注意新增草稿接口中，作者、标题、摘要、正文等度字数限制
