php微信上传图片之人脸识别

人脸识别是调用http://apicn.faceplusplus.com中的接口

info.html中的js代码

//引入
<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
<script>
wx.config({
debug: false, // 开启调试模式,调用的所有api的返回值会在客户端alert出来，若要查看传入的参数，可以在pc端打开，参数信息会通过log打出，仅在pc端时才会打印。
appId: '<?php echo $jssdk["appId"];?>', // 必填，公众号的唯一标识
timestamp: '<?php echo $jssdk["timestamp"];?>', // 必填，生成签名的时间戳
nonceStr: '<?php echo $jssdk["nonceStr"];?>', // 必填，生成签名的随机串
signature: '<?php echo $jssdk["signature"];?>', // 必填，签名，见附录1
jsApiList: ['checkJsApi', 'chooseImage', 'uploadImage', 'downloadImage', 'previewImage'] // 必填，需要使用的JS接口列表，所有JS接口列表见附录2
});
var images = {
localId: [],
serverId: []
};
var cb=1;
wx.ready(function() {
// config信息验证后会执行ready方法，所有接口调用都必须在config接口获得结果之后，config是一个客户端的异步操作，所以如果需要在页面加载时就调用相关接口，则须把相关接口放在ready函数中调用来确保正确执行。对于用户触发时才调用的接口，则可以直接调用，不需要放在ready函数中。
$('#selectImage').click(function () {

调用识别接口

<?php
//测试函数
class face_recognitionMod extends comMod {

public function __construct()
{
parent::__construct();
}

// 调用人脸识别的API返回识别结果
public function face($imgUrl)
{
// face++ 链接
$jsonStr =
file_get_contents("http://apicn.faceplusplus.com/v2/detection/detect?api_key=*******&api_secret=******&url=".$imgUrl."%3Fv%3D2&attribute=age%2Cgender%2Crace%2Csmiling%2Cpose%2Cglass");
$replyDic = json_decode($jsonStr);
//         $resultStr = "";
$faceArray = $replyDic->{'face'};

return $faceArray;
}

}
