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 🙏

读取相册API chanjet-plgin-choose-photo

在mutants框架中, 提供从相册中选择照片的功能 , 目前支持chanjet平台, 后期增加微信.

不能脱离mutants框架单独使用.

获取实例

//通过mutants来获取插件实例
const plugin = mutants.plugin.choosePhoto;

API

  1. choosePhoto 选择照片

参数
  • options Object 设置选项
    • maxCount number 最大选图数量 , 默认值: 9
    • quality number 图片质量 , 0 : 高(默认) , 1 : 中 , 2 : 低
  • callback function 执行完成后回调
  • requestId string 应用自己定义的id , 用于在restore时判断使用

用法

//获取插件实例
const plugin = mutants.plugin.choosePhoto;

//定义调用参数
const options = {
  maxCount : 9,
  quality : 0
};


//定义requestId
//requestId用于在restore时帮助应用判断调用插件的业务或者逻辑.从而根据结果进行后续操作
const requestId = 'choosePhotoAtDemoPage';


//定义回调
const callback = (rs) => {
  /*
   *  rs = {
   *		resultCode : number,	//0:ok , 1:failed , 2:canceled
   *		message : string,
   *		requestId : string,
   *		body : {
   *			data : Object
   *		}
   *  }
   */

  //调用成功
  if(rs.resultCode == 0){
	//插入应用自己的代码
    console.log(rs.body);

  //调用失败
  }else if(rs.resultCode == 1){
  	//插入应用自己的代码
    console.log(rs.message);

  //用户取消
  }else{
  	//插入应用自己的代码
  }
}



/**
 * 参数说明
 * @param options
 *      @property options.maxCount 最大选图数量, 默认9张
 *      @property options.quality 0:高质量(默认) , 1:中等质量 , 2:低质量
 * @param callback 执行完成后回调
 * @param requestId 应用自己分配的值,用于在restore时判断数据来源进行后续操作.
 *
 */
plugin.choosePhoto(options , callback , requestId);

mock数据

在浏览器环境中,可以通过mock数据来模拟返回结果 , 可以使用 mutants.plugin.setMockData 来设置mock数据.

具体参考如下:

模拟成功

const mockData = {
  //mock数据中,键名为插件的类名
  ChoosePhotoPlugin : {
    status : 'success',
    //data为数组,其中包含了选择照片返回的照片地址,可自行mock
    data : ['http://www.example.com/1.png']
  }
}

//设置mock数据
mutants.plugin.setMockData(mockData);

模拟失败

const mockData = {
  //mock数据中,键名为插件的类名
  ChoosePhotoPlugin : {
    status : 'failed',
    message : 'choose photo has been failed'
  }
}

//设置mock数据
mutants.plugin.setMockData(mockData);

模拟取消

const mockData = {
  //mock数据中,键名为插件的类名
  ChoosePhotoPlugin : {
    status : 'cancel'
  }
}

//设置mock数据
mutants.plugin.setMockData(mockData);
