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 🙏

基于axios封装的请求库

Readme

@eliduty/request

npm npm

基于axios封装的请求库。

  • 基于TypeScript,拥有更好的类型推断和代码提示。
  • 基于Class封装支持多请求实例配置。
  • 更加灵活的请求拦截器和响应拦截器。
  • 支持响应结果转换器。
  • 支持实例配置取消重复请求(默认开启),同时支持单个请求关闭。

安装

npm install @eliduty/request
// 或
yarn add @eliduty/request
// 或
pnpm install @eliduty/request

基本使用

import Request from '@eliduty/request';
const request = new Request({
  baseURL:'/api',
  timeout: 10 * 1000,
  // 拦截器配置
  interceptors:{

  },
  // 生成请求KEY方法,可选
  generateRequestKey(config){
    return KEY
  }
});

该工具库也导出了原始axios请求实例和HTTP状态码字典,使用方式如下:

import { axios , HTTP_STATUS } from '@eliduty/request';

HTTP_STATUS 字典如下:

{
  400: '请求参数错误',
  401: '未授权, 请重新登录',
  403: '服务器拒绝本次访问',
  404: '请求错误,未找到该资源',
  405: '请求方法未允许',
  408: '请求超时',
  409: '请求发生冲突',
  410: '请求的资源已删除',
  413: '请求体过大,服务器无法处理',
  414: '请求url过长',
  415: '不支持的媒体类型',
  429: '请求次数超过限制',
  500: '服务器端内部错误',
  501: '服务器不支持该请求中使用的方法',
  502: '网络错误',
  503: '服务不可用',
  504: '网关超时',
  505: 'HTTP版本不受支持'
}

类型说明

请求配置

请求配置继承于AxiosRequestConfig,除AxiosRequestConfig配置选项外,还支持以下配置:

/**
 * 自定义请求参数
 */
export interface RequestConfig<D = any> extends AxiosRequestConfig<D> {
  /**
   * 忽略终止重复请求,默认:false
   * 可以在实例配置,也可以单独在接口开启
   */
  ignoreAbortRequest?: boolean;

  /**
   * 设置在请求未响应之前,多长时间内不允许发送相同请求
   * 可以在实例配置,也可以单独在接口开启
   */
  abortPendingTime?: number;

  /**
   * 指定当前请求的key,
   * 如果传递该参数,则会覆盖generateRequestKey生成的key
   * */
  requestUniqueKey?: string;
}

拦截器类型说明

/**
 * 拦截器配置
 */
interface RequestInterceptors<D = any, R = any> {
  /**
   * 请求成功拦截器
   * @param config
   * @returns
   */
  requestInterceptor?: (config: InternalAxiosRequestConfig<D>) => InternalAxiosRequestConfig<D> | Promise<InternalAxiosRequestConfig<D>>;

  /**
   * 请求失败拦截器
   * @param err
   * @returns
   */
  requestInterceptorCatch?: (err: any) => any;

  /**
   * 请求拦截器配置
   */
  requestInterceptorOption?: AxiosInterceptorOptions;

  /**
   * 响应拦截器配置
   * @param response
   * @returns
   */
  responseInterceptor?: <T extends R = R>(response: AxiosResponse<T, R>) => any;

  /**
   * 响应失败拦截器配置
   * @param err
   * @returns
   */
  responseInterceptorCatch?: (err: AxiosError<R>) => any;

  /**
   * 响应拦截器
   */
  responseInterceptorOption?: AxiosInterceptorOptions;
}

其它说明

  1. 在默认情况下,该库默认开启了请求取消功能,如需自定义控制可通过请求配置参数ignoreAbortRequest进行控制。

完整示例

import Request from '@eliduty/request';

interface ResponseType {
  code: number;
  message: number;
  data: any;
}

const request = new Request<ResponseType>({
  timeout: 30000,
  baseURL: '',
  interceptors: {
    requestInterceptor(config) {
      config.headers['App-Version'] = 'v0.1.0';
      config.headers['Authorization'] = 'string';
      config.headers['Some-Header-Key'] = 'Some-Header-Value';
      return config;
    },
    requestInterceptorCatch(err) {
      console.log('requestInterceptorCatch', err);
      return err;
    },
    responseInterceptor({ data }) {
      if (data.code === 200) {
        return Promise.resolve(data.data);
      } else {
        return Promise.reject(data);
      }
    },

    responseInterceptorCatch(error) {
      const { response, code } = error;
      if (code === 'ERR_CANCELED') return Promise.reject(new Error('请求取消'));

      if (!response) return Promise.reject(new Error('网络异常,请检查网络连接'));

      if (response.status === 401) {
        // console.log('请求配置', config);
        return Promise.reject(new Error('未授权'));
      }

      if (response.status === 500) {
        return Promise.reject(new Error('服务器异常'));
      }

      // 其它情况处理

      return Promise.reject(response);
    }
  }
});

export const get = request.get.bind(request);
export const post = request.post.bind(request);
export const put = request.put.bind(request);
export const patch = request.patch.bind(request);
export const del = request.delete.bind(request);

export default request;

迁移指南

  1. 取消请求参数由ignoreCancelToken变成了ignoreAbortRequest
