久久久久久久久毛片,色吧久久,国内自拍偷拍视频

首先我們先確認(rèn)我們的百度云人臉庫里已經(jīng)上傳了我們的個(gè)人信息照片

然后我們?cè)诤笈_(tái)寫刷臉登陸的接口login我們要把拍照獲取的照片存儲(chǔ)到服務(wù)器

public function login(){ 
   // 上傳文件路徑 
   $dir = "./Uploads/temp/"; 
   if(!file_exists($dir)){ 
    mkdir($dir,0777,true); 
   } 
   $upload = new \Think\Upload(); 
   $upload->maxSize = 2048000 ;// 設(shè)置附件上傳大小 
   $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 設(shè)置附件上傳類型 
   $upload->savepath = ''; 
   $upload->autoSub = false; 
   $upload->rootPath = $dir; // 設(shè)置附件上傳根目錄 
   // 上傳單個(gè)文件 
   $info = $upload->uploadOne($_FILES['file']); 
   if(!$info) {// 上傳錯(cuò)誤提示錯(cuò)誤信息 
     echo json_encode(array('error'=>true,'msg'=>$upload->getError()),JSON_UNESCAPED_UNICODE); 
   }else{// 上傳成功 獲取上傳文件信息 
    $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(shí)別成功' . json_encode($data,JSON_UNESCAPED_UNICODE); 
     }else{ 
      echo '識(shí)別失敗' . $data['score']; 
     } 
    } 
   } 
  }

然后進(jìn)行前臺(tái)設(shè)計(jì)

<camera device-position="{{device?'back':'front'}}" flash="off" binderror="error" style="width: 100%; height: 300px;"></camera> 
    <view class="weui-cells__title" >開關(guān)</view> 
    <view class="weui-cells weui-cells_after-title"> 
      <view class="weui-cell weui-cell_switch"> 
        <view class="weui-cell__bd">切換攝像頭</view> 
        <view class="weui-cell__ft" > 
          <switch bindtap="devicePosition" /> 
        </view> 
      </view> 
    </view> 
<button type="primary" bindtap="takePhoto">刷臉登錄</button>

我們還可以控制相機(jī)的前后鏡頭

devicePosition() { 
this.setData({ 
 device: !this.data.device, 
}) 
console.log("當(dāng)前相機(jī)攝像頭為:", this.data.device ? "后置" : "前置"); 
camera() { 
 let { ctx, type, startRecord } = this.data; }, 
data: { 
 src: null, 
},

在js里面調(diào)用接口

takePhoto() { 
   const ctx = wx.createCameraContext() 
   ctx.takePhoto({ 
    quality: 'high', 
    success: (res) => { 
     this.setData({ 
      src: res.tempImagePath 
     }) 
     console.log(res) 
     wx.uploadFile({ 
      url: '', //僅為示例，非真實(shí)的接口地址 
      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" 
       }) 
      } 
     }) 
    } 
   }) 
  },

刷臉登錄就成功了
