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 🙏

Usage

初始化

const OAuth = require('node-wechat-oauth');
const oauth = new OAuth('your appid', 'your secret');

以上即可满足单进程使用
当多进程时, token需要全局维护, 以下为保存token的接口
持久化时请注意, 每个openid都对应一个唯一的token!

const oauth = new OAuth('appid', 'secret', async (openid) => {
  const txt = await fs.readFile(`${openid}:access_token.txt`, 'utf8');
  return JSON.parse(txt);
}, async (openid, token) => {
  await fs.writeFile(`${openid}:access_token.txt`, JSON.stringify(token));
});

全局维护AccessToken的示例代码:

Mongoose | MySQL

引导用户

生成引导用户点击的URL

const url = oauth.getAuthorizeURL('redirectUrl', 'state', 'scope');

如果是PC上的网页, 请使用以下方式生成

const url = oauth.getAuthorizeURLForWebsite('redirectUrl');

获取OpenID和AccessToken

用户点击上步生成的URL后会被重定向到上步设置的 redirectUrl, 并且会带有code参数, 我们可以使用这个code换取access_token和用户的openid

const result = await oauth.getAccessToken('code');
const accessToken = result.data.access_token;
const openid = result.data.openid;

获取用户信息

如果我们生成引导用户点击的URL中scope参数值为snsapi_userinfo, 接下来我们就可以使用openid换取用户详细信息 ( 必须在getAccessToken方法执行完成之后 )

const userinfo = await oauth.getUser(openid);
