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

http请求工具,封装微信小程序、支付宝小程序、uni-app的request请求使其可以实现类似axios的调用方式

实现情况

  • ✅ 微信小程序
  • ✅ 支付宝小程序
  • ✅ uni-app

创建一个公用的请求实例

import Fetch from '@zhangjr0575/request';
// 实例化支持baseURL, headers以及timeout
const request = new Fetch({
    baseURL: 'http://wthrcdn.etouch.cn'
});

添加一个请求拦截器

拦截器我们可以创建多个,因为我们并没有限制允许设置的拦截器的上限数量

request.interceptors.request.use(function(config) {
    // TODU
    return config;
});

当我们返回一个false或则Promise.reject()时,当前请求将会被终止

request.interceptors.request.use(function(config) {
    return Promise.reject();
});

添加一个响应拦截器

响应体内容统一类型格式为{data: any; headers: Record<string, string>; statusCode: number}

request.interceptors.response.use(function(res) {
    // TODU
    return res;
});

添加一个异常拦截器

任何非200的http请求状态将会在这里被监听到, 异常内容统一类型格式为{errCode: number; errMsg: string}

request.interceptors.httpError.use(function(res) {
    // TODU
    return res;
});

发起一个http请求

request.get('/weather_mini1', { city: '成都' }).then(res => {
    console.log(res);
}).catch(error => {
    console.log(error);
});

移除一个拦截器

当我们添加一个拦截器后会返回一个值, 此时我们可以记录这个值并使用eject在适当的时候移除这个拦截器

const interceptorId = request.interceptors.response.use(function(res) {
    // TODU
    return res;
});
// TODU
request.interceptors.response.eject(interceptorId);
