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 🙏

wei

用于微信签名和微信登陆的一个node模块,该模块推荐配合 ea7 async/await使用,最初开发为在thinkjs2.0中使用,如在其他平台使用出现bug,可与本人取得联系。

安装

npm install wei --save

用法简介

wei.token( appid , appsecret);

用于获取全局tokenjsapi-ticket,方法返回Promise。可根据业务需要缓存结果。根据微信规定,该数据7200s内有效。请注意刷新。 格式如下:

//正确返回结果
{
	token : token,
	ticket : ticket,
	timestamp : 时间戳秒数
}
//错误返回
{
	errno : -1,
	errmsg : 'get token or ticket failed'
}

wei.sign( jsapi_ticket , url )

方法用于给url签名。第一个参数为jsapi_ticket,该参数应为wei.token()方法中获取的ticket,请根据业务需要进行缓存,勿频繁调用wei.token方法。该方法直接返回结果。使用示例:

var sign = wei.sign( jsapi_ticket , url );

{
	jsapi_ticket : jsapi_ticket, //使用token换来的票据
	nonceStr: nonceStr, //随机字符串
	timestamp: timestamp, //时间戳
	url: url, //签名的url地址
	signature : signature //签名结果
}

wei.authorize_url( appid , redirect_uri )

方法为静态方法,返回一个url,业务需要跳转至该url进行授权。示例

var authorize_url = wei.authorize_url( appid ,redirect_uri );

http.redirect( authorize_url );

wei.authorize( config , hooks )

使用该方法会进行一系列认证,直到拿到用户信息。因为openid是唯一的,所以在第一步请求拿到access_token后,会有一个hook。可以用该hook执行查库等逻辑,如果查到则给方法返回信息即可。未查到可不返回。或者返回空。使用示例。方法返回promise。


wei.authorize({
	appid : appid,
	appsecret : appsecret,
	code : code //此处code可在授权后重定向的url上拿到。
},{
	check : function(){
		return ''; //此处可返回userinfo,如未查到则返回空。
	}
})
