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 🙏

Vue 纯前端的拼图人机验证、右滑拼图验证 我知道有第 3 方的很好用,比如 GEETEST 的拼图验证,但要引入 SDK 跟后台配合,还有接口交互。 太麻烦了,有时候突然改需求来不及弄,为了应付老板,就弄了个纯前端的随便验一下得了。

DEMO: https://isluo.com/work/vue-puzzle-vcode/

img

Vue3.x的使用文档在这

以下为Vue2.x使用文档

安装

  npm install vue-puzzle-vcode --save

使用

import Vcode from "vue-puzzle-vcode";

<Vcode :show="isShow" @success="onSuccess" @close="onClose" />

IE

我没加babel-polyfill,所以在 IE 里会报错:SCRIPT1002: 语法错误(IE 不支持箭头 函数) 需要兼容 IE 的朋友,请直接复制src/app.vuesrc/assets这两个东西 到自己的项目里,给app.vue随便改个名字,就是个普通 vue 组件,直接用即可。 src/assets里是一张小图片,app.vue中有引用,注意自己匹配一下引用路径

最简单例子

<template>
  <div>
    <Vcode :show="isShow" @success="onSuccess" @close="onClose" />
    <button @click="submit">开始验证</button>
  </div>
</template>

<script>
import Vcode from "vue-puzzle-vcode";
export default {
  data() {
    return {
      isShow: false,
    };
  },
  components: {
    Vcode,
  },
  methods: {
    submit() {
      this.isShow = true;
    },

    onSuccess(msg) {
      this.isShow = false; // 通过验证后,需要手动关闭模态框
    },

    onClose() {
      this.isShow = false;
    },
  },
};
</script>

参数

| 字段 | 类型 | 默认值 | 说明 | | ------------ | ------- | ------------------ | ----------------------------------------------------------------------------- | | show | Boolean | false | 是否显示验证码弹框 | | canvasWidth | Number | 310 | 主图区域的宽度,单位 px | | canvasHeight | Number | 160 | 主图区域的高度,单位 px | | puzzleScale | Number | 1 | 拼图块(小的拼图)的大小比例,0.2 ~ 2 ,数字越大,拼图越大 | | sliderSize | Number | 50 | 左下角用户拖动的那个滑块的尺寸,单位 px | | range | Number | 10 | 判断成功的误差范围,单位 px, 滑动的距离和拼图的距离小于等于此值时,会判定重合 | | imgs | Array | null | 自定义图片,见下方例子 | | successText | String | "验证通过!" | 验证成功时的提示文字 | | failText | String | "验证失败,请重试" | 验证失败时的提示文字 | | sliderText | String | "拖动滑块完成拼图" | 下方滑动条里的文字 |

事件

| 事件名 | 返回值 | 说明 | | ------- | ------ | ------------------------------------------------------------- | | success | 偏差值 | 验证通过时会触发,返回值是用户移动的距离跟目标距离的偏差值 px | | fail | 偏差值 | 验证失败时会触发,返回值同上 | | close | null | 用户点击遮罩层的回调 |

自定义图片

<template>
  <Vcode :imgs="[Img1, Img2]" />
</template>

<script>
import Img1 from "~/assets/img1.png";
import Img2 from "~/assets/img2.png";

export default {
  data() {
    return {
      Img1,
      Img2,
    };
  },
};
</script>
  • 也可以是网络图片完整 URL 路径,但注意图片跨域问题,因为 canvas api 无法对跨域的图片进行操作

说明

  • 当不传递 imgs 字段或图片加载出错时,会自动生成随机图片
  • 模态框的显示和隐藏完全由父级控制,所以用户通过验证后,需要手动隐藏模态框

更新日志
