PHP使用Face++接口开发微信公众平台人脸识别系统的方法


            本文实例讲述了PHP使用Face++接口开发微信公众平台人脸识别系统的方法。分享给大家供大家参考。具体如下：

效果图如下：





具体步骤如下：

首先，先登录Face++的官网注册账号：官网链接

注册之后会获取到api_secret和api_key，这些在调用接口的时候需要用到。

然后接下来的就是使用PHP脚本调用API了。

在使用PHP开发微信公共平台的时候，推荐使用Github上的一款不错的框架：wechat-php-sdk

对于微信的常用接口做了一些封装，核心文件wechat.class.php如下：
