網頁訪問localhost//weixin.php微信

微信公衆號須要服務器須要域名這時候咱們能夠在新浪雲註冊個域名，大概須要10塊錢一個月的，上傳代碼
curl

不想申請域名咱們本地也能夠，先註冊個花生殼，localhost查看下ip地址，在c盤Windows/System32/drivers/etc/HOSTS文件設置下ip，而後花生殼映射下ip，當前主機，網頁訪問花生殼內容外網就能夠訪問咱們的項目了工具

註冊微信公衆號並登錄https://mp.weixin.qq.com/,而後找到開發，開發者工具，找到公衆平臺測試號，接口配置信息修改，url寫花生殼域名，Token隨便寫上面代碼要用，我寫的weixinpost

這時候手機打開微信掃下二維碼就能夠了測試
