laravelVerification code

This article mainly introduces the method of integrating Geetest verification code with Laravel. The editor thinks it is quite good, so I will share it with you now and give it as a reference. Let’s follow the editor and take a look.

Geetest integration process

The general logic of realizing login
Register a JiExperience account
Register a behavioral verification in the background management of “JiExperience”
Configure our controller and routing according to the official Demo
Configure our login template according to the official Demo
Test

Geetest integration detailed process

1. Implement the general logic of login

Create the controller php artisan make:controller GeetestController

Edit Controller/app/Http/Controllers/GeetestController

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
/**
* 这是一个集成 Geetest 验证码的 Demo 类
*/
class GeetestController extends Controller
{ 
 /**
 * 导入登录视图
 */
 public function login() {
  return view(&#39;Geetest/login&#39;);
 }
 **
 * 验证用户信息
 */
 public function check() {
  return &#39;用户已经在前端通过了验证码验证, 你可以在这里完善后续的逻辑&#39;;
 }
}

The view is a simple form, omitted .

2. Omit => "Register"

3. Omit => "Backend login" => "Behavior verification" => Apply for an id & key

4. Configure the controller and routing

First of all, the core class library provided by the Demo is a class file called class.geetestlib.php, and the class name is GeetestLib. We create a controller with the same class name to replace it php artisan make:controller GeetestLib

Don’t copy the class, just copy the content in the class

GeetestController control Device implementation logic

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\GeetestLib; // 我们创建然后拷贝得来的 GeetestLib 核心库

/**
* 这是一个集成 Geetest 验证码的 Demo 类
*/
class GeetestController extends Controller
{ 
 // 这里配置 id & key
 private $captchaId = "5d467a3cb22a9310837d51720c5251f0";
 private $privateKey = "40764e6b94344f780d4b6b07148c9495";

 /**
 * 导入登录视图
 */
 public function login() {
  return view(&#39;Geetest/login&#39;);
 }

 /**
 * 验证用户信息
 */
 public function check() {
  return &#39;用户已经在前端通过了验证码验证, 你可以在这里完善后续的逻辑&#39;;
 }

 /**
 * 实现验证功能： 直接复制官方demo提供得
 */
 public function startCaptchaServlet() {
  // 这里使用配置的 id & key
  $GtSdk = new GeetestLib($this->captchaId, $this->privateKey);
  session_start();
  
  $data = array(
   "user_id" => "test", # 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" => "127.0.0.1" # 请在此处传输用户请求验证时所携带的IP
  );
  
  $status = $GtSdk->pre_process($data, 1);
  $_SESSION[&#39;gtserver&#39;] = $status;
  $_SESSION[&#39;user_id&#39;] = $data[&#39;user_id&#39;];
  echo $GtSdk->get_response_str();
 }
}

Configuration routing/routes/web.php

// 集成 Geetest 验证码
Route::get(&#39;GeetestLogin&#39;, &#39;GeetestController@login&#39;); //登录页面
Route::get(&#39;GeetestCheck&#39;, &#39;GeetestController@check&#39;); //登录验证 （我们没写具体逻辑）
Route::get(&#39;GeetestStartCaptchaServlet&#39;, &#39;GeetestController@startCaptchaServlet&#39;); // 调用方法启用验证码

5. Improve the login template/resources/views/Geetest/login.blade.php

Need to import jquery (we use npm run dev compiled app.js to integrate jquery)

Need to import Demo to give gt.js, we put it under public/js<script src="/js/gt.js"></script>

In fact, in theory, it can also be placed under /resouces/assets/js/, and require in /resouces/assets/js/app.js to let it participate in being compiled, and package it directly in public/js The integration takes effect.

On the template, two style classes need to be defined.show & .hide => The styles used for gt.js control prompt information can also be written under /resouces/assets/sass/

Submit an id to the "Login" button in the form

Copy the front-end logic js provided in the Demo, pay attention to binding this button

Pay attention to the .ajax configuration The url must be the path we defined in web.php with 'GeetestStartCaptchaServlet'

Specific code

<!DOCTYPE html>
<html lang="zh-CN">
<head>
 <meta charset="UTF-8">
 <meta name="viewport" content="width=device-width, initial-scale=1.0">

 <!-- 这是我们用 npm run dev 编译后的 css / js -->
 <link rel="stylesheet" href="/css/app.css" rel="external nofollow" >
 <script src="/js/app.js"></script>

 <!-- 这里需要用到两个样式 -->
 <style>
  .show {
   display: block;
  }
  .hide {
   display: none;
  }
 </style>

 <!-- 引用 gt.js -->

     e.preventDefault();
    }
   });
   // 将验证码加到id为captcha的元素里，同时会有三个input的值：geetest_challenge, geetest_validate, geetest_seccode
   captchaObj.appendTo("#embed-captcha");
   captchaObj.onReady(function () {
    $("#wait")[0].className = "hide";
   });
   // 更多接口参考：http://www.geetest.com/install/sections/idx-client-sdk.html

    }, handlerEmbed);
   }
  });

Test Success

Things that can be optimized

It is best not to use a "controller" as the core class library. GeetestLib should be integrated into another place

The js & css on the view template should be written in resources/assets to participate in the compilation of generating app.css & app.js

We have not written the specific login logic. You should also be able to confirm whether the Geetest verification is successful in the login verification check() method. You can refer to Demo
