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 🙏

简介

一个基于Promise对微信小程序原生请求方法 wx.request 进行二次封装的请求工具。

发送一个请求

axios({
  url: 'https://www.baidu.com',
  method: 'GET',
  params: {
    name: 123
  }
})
.then(res => {
  console.log(res)
})

添加请求拦截器

说明

通过baseUrl参数,为后面的请求添加url前缀
一些公共的请求参数, 都可以在通过请求拦截器进行添加。
你需要在请求前做的一些操作,都可以在里面进行。(例如: loading动画)

实例

axios.prototype.requestBefore((config) => {
  config.baseUrl = 'https://www.baidu.com',
  config.header = {
    userType: '2'
  }
  return config
})

添加响应拦截器

说明

你可以在响应拦截器中对错误进行捕获
从而去自己对错误作出一些解释,进行抛出。
也可以在返回响应结果之前,进行一些操作。(例如: loading动画)

实例

axios.interceptors.responseBefore((res) => {
  try {
    return res
  } catch {
    throw '请求发生了一些错误'
    return res
  }
})

完整实例

import axios from '../utils/wx-miniprogram-axios/index.js'
import { baseUrl } from '../utils/base'
axios.interceptors.requestBefore((base) => {
    base.baseUrl = baseUrl
    base.header = {
    }
    return base
})
axios.interceptors.responseBefore((err) => {
    return err
})
export default axios
