qrcode2console's Introduction

qrcode2console

golang 将二维码图片输出到控制台显示

Parse QR code pictures or Base64 data, and then output to the console.

  • 为什么有这个库?
  • Why is there this library?
    • 写爬虫的时候,遇到需要扫二维码的场景,控制台可以输出,然后直接扫码。
    • When writing a crawler, you need to scan the QR code. The console can output it, and then scan the code directly.

使用【二维码识别区外不能有其他图案,否则会生成失败】

Use [no other patterns outside the QR code recognition area, otherwise the generation will fail]

go get github.com/yantao1995/qrcode2console 

支持从base64中生成

Support generation from Base64

qr, err := qrcode2console.NewQrcodeFromBase64("base64")
if err != nil {
    log.Fatalln(err)
}
qr.SetBound(1) //不设置外边框将使用原外框的最小边的缩放比例 //If the outer frame is not set, the scale of the smallest edge of the original outer frame will be used
qr.PrintForConsole()

支持从文件夹路径生成

Support generating from folder path

qr, err := qrcode2console.NewQrcodeFromPath("filePath")
if err != nil {
    log.Fatalln(err)
}
qr.SetBound(1) //不设置外边框将使用原外框的最小边的缩放比例 //If the outer frame is not set, the scale of the smallest edge of the original outer frame will be used
qr.PrintForConsole()
