本文實例講述了PHP使用Face++接口開發微信公眾平臺人臉識別系統的方法。分享給大家供大家參考。具體如下：效果圖如下：具體步驟如下：首先，先登錄Face++的網址注冊賬號：網址鏈接
注冊之后會獲取到api_secret和api_key，這些在調用接口的時候需要用到。
然后接下來的就是使用PHP腳本調用API了。
在使用PHP開發微信公共平臺的時候，推薦使用Github上的一款不錯的框架：wechat-php-sdk
對于微信的常用接口做了一些封裝，核心文件wechat.html' target='_blank'>class.php如下： php * 微信公眾平臺PHP-SDK, 官方API部分 * @author dodge dodgepudding@gmail.com * @link https://github.com/dodgepudding/wechat-php-sdk * @version 1.2 * usage: * $options = array( * 'token'= 'tokenaccesskey', //填寫你設定的key * 'appid'= 'wxdk1234567890', //填寫高級調用功能的app id * 'appsecret'= 'xxxxxxxxxxxxxxxxxxx', //填寫高級調用功能的密鑰 * );
