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 🙏

Readme

一个微信授权的node小服务。

需要自己提供一个配置文件和一个首页html。

首先npm install koa-wxauth

然后在package.json里面的script写入

"auth": "cross-env CONFIG=./config/auth.config.js PORT=80 supervisor ./node_modules/koa-wxauth"

注意此处的 auth.config.js 是自己配置的。给一个大概的参考配置:

module.exports = {
  // 注册此服务的授权路由,此服务的controller为/auth/normal
  redirect_uri: "",
  // 授权方式
  scope: "snsapi_userinfo",
  // 首页html地址
  html_src: "./views/index.html",
  // 微信app信息
  wxApp: {
    appId: "",
    appSecret: "",
    appName: "",
    id: 0
  },
  // 鉴权,判断是否需要授权,true -> 不需要授权,false -> 需要授权
  authentication: ctx => {
    let token = ctx.cookies.get("token");
    return !!token;
  },
  // 生成token
  createTOKEN(wxApp, wxUser, user) {
    const JWTUtil = require("jwt-simple");
    const JWT_SECRET = "";
    let nowDate = Math.ceil(Date.now() / 1000);
    let expDate = nowDate + 30 * 24 * 60 * 60; //30天过期时间
    let data = {
      oid: wxUser.openid,
      sub: wxUser.unionid,
      app: wxApp.appName,
      exp: expDate,
      wx_app_id: wxApp.id,
      id: wxUser.user_id
    };
    return JWTUtil.encode(data, JWT_SECRET);
  },
  // 注入token
  injectTOKEN(ctx, token) {
    const domain = "";
    const path = "/";
    ctx.cookies.set("token", token, {
      domain: domain,
      path: path,
      expires: new Date(Date.now() + 604800000)
    });
  },
  // 获取到用户数据之后,希望做一发什么样的操作,比如将用户信息插入数据库什么的
  createUser(wxUser, wxApp) {}
};
