网页访问localhost//weixin.php
微信公众号需要服务器需要域名这时候我们可以在新浪云注册个域名，大概需要10块钱一个月的，上传代码
不想申请域名我们本地也可以，先注册个花生壳，localhost查看下ip地址，在c盘Windows/System32/drivers/etc/HOSTS文件设置下ip，然后花生壳映射下ip，当前主机，网页访问花生壳内容外网就可以访问我们的项目了
注册微信公众号并登陆https://mp.weixin.qq.com/,然后找到开发，开发者工具，找到公众平台测试号，接口配置信息修改，url写花生壳域名，Token随便写上面代码要用，我写的weixin
这时候手机打开微信扫下二维码就可以了
