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 🙏

兼容性

以下兼容性根据BrowserStack的相关真机测试得出,仅供参考

  • IE9+
  • Edge 15+
  • Chrome 27+
  • Safari 6+
  • Firefox 26+
  • Android 4.4+
  • iOS Safari 7+

安装

npm install yotest-web-sdk --save

或者你可以在HTML文件中引用CDN路径

<script src="//static.fastyotest.com/assets/yotest.180d0a5.js"></script>

快速开始

当你使用npm进行安装后,你可以通过import直接引入

import initYoTest from "yotest-web-sdk";

initYoTest({
  accessId: "当前项目所属的accessId,可以在后台中进行获取及查看",
}, (captcha)=>{
  if(captcha != null){
    captcha.appendTo("#captcha");
  }
});

如果你是通过CDN路径引入,那么你也可以轻松的使用此SDK

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8" />
    <title>YoTest Web SDK Demo</title>
    <style>
      html,
      body {
        width: 100%;
        height: 100%;
      }

      #captcha {
        width: 300px;
        height: 40px;
        position: absolute;
        left: 50%;
        top: 50%;
        -ms-transform: translate(-50%, -50%);
        -webkit-transform: translate(-50%, -50%);
        transform: translate(-50%, -50%);
      }
    </style>
  </head>
  <body>
    <div id="captcha"></div>
    <script>
      initYoTest.default({
        accessId: "当前项目所属的accessId,可以在后台中进行获取及查看",
      }, (captcha) => {
        if(captcha != null) {
          captcha.appendTo("#captcha");
        }
      });
    </script>
  </body>
</html>

验证模式

  • 浮动式,默认PC展现形式,移动端不支持此模式,展示为弹窗式,设置 product: "float" 时生效

float

<div id="captcha"></div>
...
<script>
  initYoTest.default({
    accessId: "your accessId",
    product: "float",
  }, (captcha) => {
    if(captcha) {
      captcha.appendTo("#captcha");
    }
  });
</script>
  • 弹窗式,设置 product: "popup" 时生效

popup

<div id="captcha"></div>
...
<script>
  initYoTest.default({
    accessId: "your accessId",
    product: "popup",
  }, (captcha) => {
    if(captcha) {
      captcha.appendTo("#captcha");
    }
  });
</script>
  • 隐藏式,设置 product: "bind" 时生效,同时需要在onReady之后自行调用 verify 方法进行展现

bind

<script>
  initYoTest.default({
    accessId: "your accessId",
    product: "bind",
  }, (captcha) => {
    if(captcha) {
      captcha.onReady(() => {
        // 你也可以绑定事件,但需要注意:
        // 一定要在onReady之后进行verify的调用
        captcha.verify();
      });
    }
  });
</script>
  • 自定义式,设置 product: "custom" 时生效,同时需要设置 area 参数

custom

<div id="captcha"></div>
...
<script>
  initYoTest.default({
    accessId: "your accessId",
    product: "custom",
    area: "#form"
  }, (captcha) => {
    if(captcha) {
      captcha.appendTo("#captcha");
    }
  });
</script>

API

初始化函数

Captcha实例方法

initYoTest(option, callback)

  • option <Object>
    • accessId <String> 必填,当前项目所属的accessId,可以在友验后台中进行相关获取及查看
    • product <String> 可选,默认值float,设置验证码的展现形式,其值包括浮动式(float)、弹出式(popup)、绑定式(bind)、自定义式(custom)四种,具体形式可通过 验证模式 进行选择。需要注意的是,移动端由于屏幕展现原因,是无法展现浮动式(float)的
    • area <String> 可选,仅当 product: "custom" 生效,其作用为设置验证区域。需要注意的是,请确保对应的DOM元素存在,且符合CSS Selector的规范(例如:#id、.class、tagName及其组合均为合法)
    • bgColor <String> 可选,仅当 product: "custom" 生效,其设置对应验证区域的背景,支持HEX、RGB及RGBA的颜色格式
    • enforced <Boolean> 可选,默认值false,强制每一次都进行验证,取消无感验证
  • callback <Function>
    • captcha: <Captcha> 加载成功且初始化完成则返回 Captcha 实例,其具有的方法请参考下方文档说明,若加载失败,其返回为 null,请做好错误处理
  • return: undefined

初始化 YoTest ,传入相关的 option 参数,在 callback 中将会得到 YoTest 的对应实例。

initYoTest.default({
  accessId: "<your project accessId>",
  product: "custom",
  area: "#container",
  bgColor: "#ff0000",
}, function(captcha) {
  if(captcha != null){
    captcha.appendTo("#captcha");
  }
});

Captcha.prototype.appendTo(selector)

  • selector <String> 符合 CSS Selector的选择器及其组合(例如:#id、.class等)
  • return: this

用于将 Captcha 实例添加到页面之中,使其展现默认的友验按钮样式。

<div id="captcha"></div>
...
<script>
  initYoTest.default({
    accessId: "your accessId"
  }, (captcha) => {
    if(captcha){
      captcha.appendTo("#captcha");
    }
  });
</script>

Captcha.prototype.getValidate()

  • return: <Object>
    • token <String> 当前验证的凭证,需要提交给后端来进行是否通过判断
    • verified <Boolean> 是否验证成功

获取当前验证结果。

<div id="captcha"></div>
...
<script>
  initYoTest.default({
    accessId: "your accessId",
  }, (captcha) => {
    if(!captcha){
      return;
    }

    captcha.appendTo("#captcha");
    captcha.onClose(()=>{
      const { token, verified } = captcha.getValidate();
      if(verified) {
        // 通过fetch方法将token传给后端相应接口进行判断
        fetch("...?token=" + token);
      }
    });
  });
</script>

Captcha.prototype.reset()

  • return: this

重置 Captcha 当前状态为初始化状态。

<div id="captcha"></div>
<button id="reset">重置<button>
...

<script>
  initYoTest.default({
    accessId: "your accessId",
  }, (captcha) => {
    if(!captcha) {
      return;
    }

    captcha.appendTo("#captcha");
    captcha.onReady(() => {
      const $button = document.querySelector("#reset");
      $button.addEventListener("click", () => {
        captcha.reset();
      });
    });
  });
</script>

Captcha.prototype.verify()

  • return: this

当 product: "bind" 时,调用此API可以呼出验证界面并要求验证。这种方式提供了更好的灵活性,方便开发者在不破坏原由功能和UI的情况下进行集成。但需要注意的是,请在onReady后进行调用,同时 verify 不需要和 appendTo 方法一同使用。

<button id="checkcode">获取验证码</button>
...
<script>
  initYoTest.default({
    accessId: "your accessId",
  }, (captcha) => {
    if(!captcha) {
      return;
    }

    captcha.onReady(() => {
      const $checkcode = document.querySelector("#checkcode");
      $checkcode.addEventListener("click", () => {
        captcha.verify();
      });
    });
  });
</script>

Captcha.prototype.onReady(callback)

  • callback <Function> 初始化成功的回调函数,无参数
  • return: this

监听验证的初始化完成事件。

    accessId: "your accessId",
  }, (captcha) => {
    if(!captcha) {
      return;
    }

    captcha.appendTo("#captcha");
    captcha.onShow(()=>{
      console.log("yotest showed...");
    });
  });
</script>

Captcha.prototype.onSuccess(callback)

  • callback <Function>
    • data <Object> 验证成功的相关数据
      • token <String> 当前验证的凭证,需要提交给后端来进行是否通过判断
      • verified <Boolean> 是否验证成功

      console.log(code, message);
    });
  });
</script>
