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 🙏

Wafer 服务端 SDK - Node.js

介绍

Wafer 服务端 SDK 是腾讯云为微信小程序开发者提供的快速开发库,SDK 封装了以下功能供小程序开发者快速调用:

  • 用户登录与验证
  • 信道服务
  • 图片上传
  • 数据库
  • 客服消息

开发者只需要根据文档对 SDK 进行初始化配置,就可以获得以上能力。你还可以直接到腾讯云小程序控制台购买小程序解决方案,可以得到运行本示例所需的资源和服务,其中包括已部署好的相关程序、示例代码及自动下发的 SDK 配置文件 /etc/qcloud/sdk.config

安装

npm install wafer-node-sdk --save

配置

const configs = {
  appId: 'wx00dd00dd00dd00dd',
  appSecret: 'abcdefghijkl',
  useQcloudLogin: false,
  cos: {
    region: 'cn-south',
    fileBucket: 'test',
    uploadFolder: ''
  },
  serverHost: '1234567.qcloud.la',
  tunnelServerUrl: '1234567.ws.qcloud.la',
  tunnelSignatureKey: 'abcdefghijkl',
  qcloudAppId: '121000000',
  qcloudSecretId: 'ABCDEFG',
  qcloudSecretKey: 'abcdefghijkl',
  wxMessageToken: 'abcdefghijkl'
}
const qcloud = require('qcloud-weapp-server-sdk')(configs)

具体配置项说明请查看:API 文档

基本功能

用户登录与验证

用户登录使用 authorization 接口:

const { auth: { authorization } } = qcloud

// express
module.exports = (req, res) => {
  authorization(req).then(result => {
    // result : {
    //   loginState: 0  // 1表示登录成功,0表示登录失败
    //   userinfo: { // 用户信息.. }
    // }
  })
}

用户登录态校验使用 validation 接口:

const { auth: { validation } } = qcloud

// express
module.exports = (req, res) => {
  validation(req).then(result => {
    // result : {
    //   loginState: 0  // 1表示登录成功,0表示登录失败
    //   userinfo: { // 用户信息.. }
    // }
  })
}

如果你使用 Koa 框架,则可以直接使用 SDK 导出的 koaAuthorizationkoaValidation 中间件,登录信息将会被写进 ctx.state.$wxInfo

const { auth: { authorizationMiddleware, validationMiddleware } } = qcloud

// 颁发登录态
router.get('/login', authorizationMiddleware, ctx => {
  console.log(ctx.state.$wxInfo)
  // {
  //   loginState: 0  // 1表示登录成功,0表示登录失败
  //   userinfo: { // 用户信息.. }
  // }
})

// 校验登录态
router.get('/user', validationMiddleware, ctx => {
  console.log(ctx.state.$wxInfo)
  // {
  //   loginState: 0  // 1表示登录成功,0表示登录失败
  //   userinfo: { // 用户信息.. }
  // }
})

信道服务

业务在一个路由上(如 /tunnel)提供信道服务,只需把该路由上的请求都交给 SDK 的信道服务处理即可。使用信道服务需要实现处理器,来获取处理信道的各种事件,具体可参考配套 Demo 中的 tunnel.js 的实现。

图片上传

SDK 提供直接上传图片至腾讯云对象储存(COS)的接口,只需要将请求传入接口,即可自动上传文件到 COS 中,并返回数据:

const { uploader } = qcloud

module.exports = async ctx => {
  await uploader(ctx.req).then(data => {
    console.log(data)
    // {
    //   imgUrl: 'http://test-121000000.cosgz.myqcloud.com/abcdef.jpg',
    //   size: 1024,
    //   mimeType: 'image/jpeg',
    //   name: 'abcdef.jpg'
    // }
  })
}

数据库

SDK 还暴露出了内部使用的 MySQL 连接,由于 SDK 内部使用 Knex.js 连接数据库,SDK 暴露的 MySQL 实例就是 Knex.js 连接实例,具体使用方法可以查看 Knex.js 文档

const { mysql } = qcloud

mysql('db_name').select('*').where({ id: 1 })
// => { id:1, name: 'leo', age: 20 }

客服消息

微信提供一个客服消息处理能力,你可以使用 SDK 提供的接口快速部署一个接受客服信息的 API:

const { message: { checkSignature } } = require('../qcloud')

/**
 * 响应 GET 请求(响应微信配置时的签名检查请求)
 */
router.get('/message', ctx => {
  const { signature, timestamp, nonce, echostr } = ctx.query
  if (checkSignature(signature, timestamp, nonce)) ctx.body = echostr
  else ctx.body = 'ERR_WHEN_CHECK_SIGNATURE'
})

// post 请求用来接收消息
router.post('/message', (ctx, next) {
    // 检查签名,确认是微信发出的请求
    const { signature, timestamp, nonce } = ctx.query
    if (!checkSignature(signature, timestamp, nonce)) ctx.body = 'ERR_WHEN_CHECK_SIGNATURE'

    /**
     * 解析微信发送过来的请求体
     * 可查看微信文档:https://mp.weixin.qq.com/debug/wxadoc/dev/api/custommsg/receive.html#接收消息和事件
     */
    const body = ctx.request.body

    ctx.body = 'success'
})
