PHP實現微信小程式Face Service刷臉登入功能

本文通過執行個體代碼給大家講解了基於PHP實現小程式Face Service刷臉登入功能，感興趣的朋友一起學習吧

首先我們先確認我們的百度雲人臉庫裡已經上傳了我們的個人資訊照片

然後我們在後台寫刷臉登陸的介面login我們要把拍照擷取的照片儲存到伺服器

public function login(){    // 上傳檔案路徑    $dir = "./Uploads/temp/";    if(!file_exists($dir)){     mkdir($dir,0777,true);    }    $upload = new \Think\Upload();    $upload->maxSize = 2048000 ;// 設定附件上傳大小    $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 設定附件上傳類型    $upload->savepath = '';    $upload->autoSub = false;    $upload->rootPath = $dir; // 設定附件上傳根目錄    // 上傳單個檔案    $info = $upload->uploadOne($_FILES['file']);    if(!$info) {// 上傳錯誤提示錯誤資訊      echo json_encode(array('error'=>true,'msg'=>$upload->getError()),JSON_UNESCAPED_UNICODE);    }else{// 上傳成功 擷取上傳檔案資訊     $file = $dir . $info['savepath'].$info['savename'];     $image = base64_encode(file_get_contents($file));     $client = $this->init_face();     $options['liveness_control'] = 'NORMAL';     $options['max_user_num'] = '1';     $ret = $client->search($image,'BASE64','student',$options);     // echo json_encode($ret,JSON_UNESCAPED_UNICODE);     // exit;     if($ret['error_code']==0){      $user = $ret['result']['user_list'][0];      $no = $user['user_id'];      $score = $user['score'];      if($score>=95){       $data = M('student')->where("no = '{$no}'")->find();       $data['score'] = $score;       // $data['name'] = json_decode($data['name'],true);       // $data['sex'] = json_decode($data['sex'],true);       echo '識別成功' . json_encode($data,JSON_UNESCAPED_UNICODE);      }else{       echo '識別失敗' . $data['score'];      }     }    }   }

然後進行前台設計

<camera device-position="{{device?'back':'front'}}" flash="off" binderror="error" style="width: 100%; height: 300px;"></camera>     <view class="weui-cells__title" >開關</view>     <view class="weui-cells weui-cells_after-title">       <view class="weui-cell weui-cell_switch">         <view class="weui-cell__bd">切換網路攝影機</view>         <view class="weui-cell__ft" >           <switch bindtap="devicePosition" />         </view>       </view>     </view> <button type="primary" bindtap="takePhoto">刷臉登入</button>

我們還可以控制相機的前後鏡頭

devicePosition() { this.setData({  device: !this.data.device, }) console.log("當前相機網路攝影機為:", this.data.device ? "後置" : "前置"); camera() {  let { ctx, type, startRecord } = this.data; }, data: {  src: null, },

在js裡面調用介面

takePhoto() {    const ctx = wx.createCameraContext()    ctx.takePhoto({     quality: 'high',     success: (res) => {      this.setData({       src: res.tempImagePath      })      console.log(res)      wx.uploadFile({       url: '', //僅為樣本，非真實的介面地址       filePath: this.data.src,       name: 'file',       formData: {       },       success: function (res) {        // var data = res.data        // var json = JSON.parse(data)        console.log(res)        wx.showModal({         title: "提示",         content: res.data,         showCancel: false,         confirmText: "確定"        })       }      })     }    })   },

刷臉登入就成功了
