ddddocr验证码识别

1. java版本

参考 =gitee_search java 11
改造使用 jdk1.8

}

2. nodejs版本

安装包
npm install ddddocr
安装的包，报错，需要 修改 ddddocr/dist/index.js 最后一行为  ports = DdddOcr;测试
const Ddddocr  = require('ddddocr')var fs = require('fs') //引入fs模块
var path = require('path')var imgDir = "D:/verifies"var array = fs.readdirSync(imgDir)
array.forEach(item => {var file = path.join(imgDir, ate().then(async ddddocr => {// 也可传入 文件路径	const verifyCode = await ddddocr.classification(file);console.log(file, verifyCode)})})

3. Python版本

pip install ddddocrimport osimport ddddocr# ，  beta=
ocr = ddddocr.DdddOcr()# dirPath = r'D:uploadimg'
dirPath = r'D:verifies'
for ff in os.listdir(dirPath):path = os.path.join(dirPath, ff)with open(path, 'rb') as f:img_bytes = f.read()res = ocr.classification(img_bytes)print('路径:' + path + ', 识别出的验证码为：' + res)
