nodeJS实现识别验证码（tesseract-ocr+GraphicsMagick）

背景 最近在写一个爬虫的小工具，卡在登录这里。 想爬的网站需要登录才能获取数据，登录又需要输入验证码。 好在验证码是简单的验证码，还可以自己识别试试。 需求分析 1、保存验证码图片 2、识别验证码 3、对识别的验证码进行人工校准 功能实现 1、保存验证码图片 虽然每个网站不一定一样，但是大体的思路是差不多的，我要爬取的网站是后台返回了一个验证码图片和cookie，所以我们需要把这两个东西都存下来。 这里用到了node中的request模块，具体没什么好说的，请求后获取response中的set-cookie，然后再把图片流存下来。 request文档 let cookie = ""; let options = { url: "" headers: { Accept: "*/*", "Accept-Encoding": "utf-8", "Accept-Language": "zh-CN,zh;q=0.8", Connection: "keep-alive",'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36',//伪装浏览器 }, method: 'GET', }; let

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Background. AOI software needs to use the OCR feature to recognize the texts on the chips. Because our vision software is based on OpenCV, so the first choice is text module in opencv_contrib. Procedures. OCR module is not in standard OpenCV package. It is in text module of OpenCV_Contrib. It can be downloaded from opencv_contrib. The core of OCR is using Tesseract, and Tesseract depends on Leptonica, so need to build Leptonica and Tesseract first. Get the Leptonica from https://github.com/charlesw/tesseract-vs2012 . This project can directly build. The
