ThinkPHP5实现极验滑动验证码geetest功能

一时失言乱红尘 2023-06-26 05:53 147阅读 0赞

现在很多网站，比如淘宝，京东等都改用使用极验拖动验证码实现登录，这种方式比传统的验证码方式有更好的体验，减少用户输入的错误，也同样能起到防盗刷的功能。现在很多极验都是第三方的，也很多都是收费的。这里主要介绍thinkphp整合系列之极验滑动验证码geetest，官网：http://www.geetest.com

具体如下：

**一：注册获取key**

**二：导入sdk**

`/ThinkPHP/Library/Org/Xb/GeetestLip.class.php（此处GeetestLip.class.php是我重新命名的geetest类文件，原名为class.geetestlib.php）`

此处牵扯到thinkphp引入第三方类，我把第三方类放到Org/Util/Xb下面了，同时对该类文件加入命名空间如下，否则实例化类时找不到文件

**三：生成验证样式**

          $(".reloadverify").click(function(){
            if( verifyimg.indexOf('?')>0){
              $(".verifyimg").attr("src", verifyimg+'&random='+Math.random());
            }else{
              $(".verifyimg").attr("src", verifyimg.replace(/\?.*$/,'')+'?'+Math.random());

            <li>
              <input class="input" id="username" name="username"type="text" title="用户名" data-rule="required;username" placeholder="用户名" />
              <span class="msg-box n-right" style="position:absolute; left: 248px; top: 12px; " for="username"></span>

    <script>
      var handler = function (captchaObj) {
        // 将验证码加到id为captcha的元素里
        captchaObj.appendTo("#captcha");
       };
      // 获取验证码
      $.get("{:U('Admin/Public/verifys')}", function(data) {
        // 使用initGeetest接口
        // 参数1：配置参数，与创建Geetest实例时接受的参数一致

        initGeetest({
          gt: data.gt,
          challenge: data.challenge,
          product: "float", // 产品形式
          offline: !data.success,
          new_captcha:'true',
          width:'260px',
        }, handler);
      },'json');
    </script>
    </body>
    </html>

**四：验证函数**

/Application/Common/Common/function.php

/**
     * geetest检测验证码
     */
    function geetest_chcek_verify($data){
      $geetest_id = "7149e2021d7938157e";
      $geetest_key = "62b92039e1e9cf9455";
      $geetest=new \Org\Util\Xb\GeetestLib($geetest_id,$geetest_key);
      $user_id=$_SESSION['geetest']['user_id'];
      $ip_address=$_SESSION['geetest']['ip_address'];
      $dataa = array(
        "user_id" => $user_id, # 网站用户id
        "client_type" => "web", #web:电脑上的浏览器；h5:手机上的浏览器，包括移动应用内完全内置的web_view；native：通过原生SDK植入APP应用的方式
        "ip_address" => $ip_address, # 请在此处传输用户请求验证时所携带的IP
      );
      if ($_SESSION['geetest']['gtserver']==1){
        $result=$geetest->success_validate($data['geetest_challenge'], $data['geetest_validate'], $data['geetest_seccode'], $dataa);
        //return $result;
        if ($result) {
          //return 11;
          return true;
        } else{
          //return 22;
          return false;
        }
      }else{
        if ($geetest->fail_validate($data['geetest_challenge'],$data['geetest_validate'],$data['geetest_seccode'])) {
          //return 33;
          return true;  
        }else{
          //return 44;
          return false;
        }
      }
    }
    //获取id地址
    function GetIP() {
      if (!empty($_SERVER["HTTP_CLIENT_IP"])) {
        $cip = $_SERVER["HTTP_CLIENT_IP"];
      } elseif (!empty($_SERVER["HTTP_X_FORWARDED_FOR"])) {
        $cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
      } elseif (!empty($_SERVER["REMOTE_ADDR"])) {
        $cip = $_SERVER["REMOTE_ADDR"];
      } else {
        $cip = "无法获取！";
      }
      return $cip;
    }

**五：php 生成验证码 并 验证**

//极速验证
      public function verifys(){
        //require_once dirname(dirname(dirname(__FILE__))) . '/lib/class.geetestlib.php';
        //require_once dirname(dirname(__FILE__)) . '/config/config.php';
        // $GtSdk = new GeetestLib(CAPTCHA_ID, PRIVATE_KEY);
        $geetest_id = "7149e2021d7938157e9";
        $geetest_key = "62b92039e1e9cf";
        $geetest=new \Org\Util\Xb\GeetestLib($geetest_id,$geetest_key);
        //dump($geetest);die;
        $user_id = "test";
        $data = array(
          "user_id" => $user_id, # 网站用户id
          "client_type" => "web", #web:电脑上的浏览器；h5:手机上的浏览器，包括移动应用内完全内置的web_view；native：通过原生SDK植入APP应用的方式
          "ip_address" => GetIP(), # 请在此处传输用户请求验证时所携带的IP
        );
        $status = $geetest->pre_process($data,1);
        //dump($status);
        $_SESSION['geetest']=array(
          'gtserver'=>$status,
          'user_id'=>$user_id,
          'ip_address'=>GetIP(),
          );
        echo $geetest->get_response_str();
      }
     public function cdtsh_log_smfyws() {
        if ($_SESSION['userid']) {
          $this->redirect('Admin/Index/Index');
        } else {
          if (IS_POST) {
            $username = $_POST['username'];
            $password = $_POST['password'];
            //$geetest_challenge = $_POST['geetest_challenge'];
            //$geetest_validate = $_POST['geetest_validate'];
            //$geetest_seccode = $_POST['geetest_seccode'];
            $data=I('post.');
            if($data['geetest_challenge']=="" || $data['geetest_validate']=="" ||$data['geetest_seccode']=="" ){
              $this->error('请进行图形验证');
            }else{
              //dump(geetest_chcek_verify($data));
              if (geetest_chcek_verify($data)){
                //echo '验证成功';
                if ($this->loginAdmin($username, $password)) {
                  $data = M("User")->where("username='".$username."' and password='".md5($password)."'")->find();
                  if ($data["status"] != 1) {
                    //判断是否禁用
                    $this->recordLoginAdmin($_POST['username'], $_POST['password'], 0, "账号禁用"); //记录登录日志
                    $this->error('该帐号禁用');
                  } else {
                    $save["lastlogin_time"] = time();
                    $save["lastlogin_ip"] = get_client_ip();
                    $save["login_num"] = $data["login_num"] + 1;
                    $status = M("user")->where(array("id" => $data['id']))->save($save);
                    $_SESSION['userid'] = $data['id'];
                    $_SESSION['user'] = $data['username'];
                    $_SESSION['rid'] = $data['a_Id'];
                    $this->recordLoginAdmin($_POST['username'], $_POST['password'], 1); //记录登录日志
                    $this->redirect('Admin/Index/Index');
                    //$this->success('登录成功',U('Admin/Index/Index'));
                  }
                } else {
                  $this->recordLoginAdmin($_POST['username'], $_POST['password'], 0, "账号密码错误"); //记录登录日志
                  $this->error('登录失败');
                }
              }else{
                //echo '图形验证失败';
                $this->error('图形验证失败');
              }
            }
          } else {
            $this->display();
          }
        }
      }
