Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

介绍

使用Canvas绘制二维码(图片),返回Base64或者Bolb文件对象

注意

  1. 只能绘制Ascll码,如果需要绘制中文,需要使用encodeURI对中文进行编码
  2. 遮罩方法(zheZhaoBianMa)可以任意选择,这个只会影响二维码点(二维码实际就是011010这样排列的,0绘制成白色.1绘制成黑色)的位置,请选择最适合的遮罩方法

提供方法

shengCheng

  • 参数

      {
          wenZi: '需要绘制成二维码的内容',
          jiuCuoJiBie: '["L" || "M" || "Q" || "H"]  纠错级别',
          zheZhaoBianMa: '["000" || "001" || "010" || "011" || "100" || "101" || "110" || "111"]  遮罩方法',
          chiCun: '二维码的大小',
          leiXing: '["Bolb" || "DataURL"]  返回值类型',
          yanSe: '二维码的颜色,没有默认黑色'
      }
  • 返回值(Promise)

    依据类型(leiXing)返回值,直接返回对应的值

示例

QRCode.shengCheng({
    wenZi: encodeURL('我是内容!'),
    jiuCuoJiBie: 'L',
    zheZhaoBianMa: '111',
    chiCun: 500,
    leiXing: 'DataURL'
}).then(res => {
    
})
