分享一下微信的第三方平臺(tái)授權(quán)吧，中間還是有挺多坑的唤殴，開(kāi)發(fā)前一定要仔細(xì)的看幾遍文檔
一哺窄、首先在微信申請(qǐng)成為第三方捐下，流程按著微信提示的走就好了
二、開(kāi)發(fā)授權(quán)
1萌业、接收 微信的推送 component_verify_ticket 協(xié)議
在第三方平臺(tái)創(chuàng)建審核通過(guò)后坷襟，微信服務(wù)器會(huì)向其“授權(quán)事件接收URL”每隔10分鐘定時(shí)推送component_verify_ticket。第三方平臺(tái)方在收到ticket推送后也需進(jìn)行解密（詳細(xì)請(qǐng)見(jiàn)【消息加解密接入指引】）生年，接收到后必須直接返回字符串success婴程。
點(diǎn)進(jìn)【消息加解密接入指引】后，下載SDK包抱婉，在項(xiàng)目中引入排抬，我就用ThinkPHP5舉例了
將php包放到 /extend/Wxapi/
微信SDK包位置
