Google scholar Captcha verification problem

夙愿已清 提交于 2021-02-11 13:54:14
问题 I'm working on a project for which I need to extract some data from Google Scholar. My PHP program takes a string from my local machine, passes it to the Google Scholar and on the search results page it takes out the first result and saves it to the database. I have to do this for almost 90 thousand strings/queries. The problem is that after a few hundred entries the program stops as the Google Scholar asks for captcha verification. What can I do about that? 回答1: Because Google Scholar does

首先,登录网址 packagist.org 查找 laravel captcha ,找到 mews/captcha ,根据 packagist 上的使用方法一步步来实现验证码的安装。配置composer.json文件 composer 安装: composer require mews/captcha 注册 providers (config/app.php) ,在这个数组中的最后追加如下代码: Mews\Captcha\CaptchaServiceProvider::class, 注册 aliases (config/app.php) ,在这个数组中的最后追加如下代码:(laravel 5 以后不用注册) 'Captcha' => Mews\Captcha\Facades\Captcha::class, 生成配置文件,在 Composer 命令行中输入如下命令: php artisan vendor:publish 进入 config/captcha.php 文件,修改 default 数组 可以对验证码进行样式、数量、大小上的修改。 'default' => [ 'length' => 5, 'width' => 100, 'height' => 34, 'quality' => 90, ] , 页面中使用: <div class ="row"> <div class =

How to integrate Google's reCAPTCHA in a React Native app?

末鹿安然 提交于 2021-02-04 17:37:06
问题 I haven't found any React Native library to help with reCAPTCHA, and the only Android library I found is Android-Lib-reCAPTCHA but it uses the old API (showing a cypher instead of a checkbox). I have tried to show the Javascript reCAPTCHA using react-native-webview-bridge but I couldn't make it work and it's very slow and unstable. Besides sometimes the captcha needs more space to display pictures when it's not just a checkbox. Do you know any other way than a WebView? I also checked out

如何证明你是“人”还是“机器”? 揭秘验证码技术

柔情痞子 提交于 2021-02-04 13:53:19
互联网时代,验证码肯定是人们再熟悉不过的东西。验证码可以有效防止某个黑客对某一个特定注册用户用特定程序暴力破解方式进行不断的密码尝试,用验证码已经是很多网站通行的方式。 实际上,“验证码”( CAPTCHA )其实并不是各位网友总是在不同网站上看到的难以辨认的字母组合的代名词,它的英文全称是Completely Automated Public Turing Test to Tell Computers and Humans Apart,翻译过来就是全自动区分计算机和人类的图灵测试。验证码的本质 在于区分当前访问者是“人”还是所谓的“机器”。 而验证码的存在则能够避免大多数机器通过测试,进而避免机器对系统进行大规模的恶意访问和攻击。 京东云验证码技术 京东云验证码凝聚了京东近20年人机对抗的技术沉淀,为网页、APP、小程序开发者提供立体、全面的验证码服务,高效拦截机器恶意攻击,可自动识别用户风险等级并给出不同验证难度的验证码类型,兼顾业务安全与用户极致体验。 验证码提供双重验证,用静默验证进行用户风险初判,根据风险高低决定是否需要二次验证及二次验证方式,极大提升用户体验和安全性。 京东云验证码是一套完整的人机验证机制,除一次静默验证外,二次验证不仅关注用户提供的答案,更加关注提供答案的“人”。 通过对“人”提供答案的过程进行全方位立体刻画,如访问频率、地理位置、设备指纹
