微信公众号开发（个人订阅号）

微信公众号开发

微信公众一共分为三种
1.个人订阅号

2.服务号
公司-工商营业执照
个体户-工商营业执照

3.企业号
公司-工商营业执照

我们需要先注册一下
公众号官网： https://mp.weixin.qq.com
注册之后我们填写完需要填写的信息后
我们找到开发者工具点击公众平台测试账号
我们重点需要三个重要信息
微信号、appID、appsecret
然后我们我们到后面会看到一个URL地址
我们有域名的只需要填写域名就好了
token配置weixin4j
没有域名的我们需要进行内网穿透
natapp： https://natapp.cn/

这里面我们需要进行支付宝实名认证才行
实名认证完之后我们就可以购买一个免费隧道

购买之后我们下载一个客户端进行使用

我们就以windows为例
在这里插入图片描述
使用步骤我们可以在官网进行查看
然后下载一个下载一个config.ini文件
我们只需要修改下载一个config.ini文件的一处即可使用
然后点击exe文件启动

代码
