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 🙏

StatusCodeRequestPlugin

用途:对后端返回的 code 进行处理,并返回 Response 中的 data

实例化参数

| 参数名 | 用途 | 类型 | 默认值 | | --------------- | ---------------- | -------------------- | ------ | | successCode | 请求成功状态码 | number \| number[] | 200 | | fields | 状态码字段配置 | StatusCodeFields | 见下文 | | errorCallback | 请求失败回调函数 | function | - |

请求选项

| 参数名 | 用途 | 类型 | 默认值 | | --------------- | ------------------ | -------------------- | ------ | | useStatusCode | 是否使用状态码判断 | boolean | true | | successCode | 成功状态码 | number \| number[] | - |

状态码字段配置

StatusCodeFields 类型如下:

| 参数名 | 用途 | 类型 | 默认值 | | ---------------- | -------------------------- | -------- | ----------- | | codeField | 状态码字段名 | string | 'code' | | statusField | 状态字段名 | string | 'status' | | messageField | 消息字段名 | string | 'message' | | dataField | 数据字段名 | string | 'data' | | errorField | 错误对象字段名 | string | 'error' | | errorCodeField | 错误对象中的错误码字段名 | string | 'code' | | errorDescField | 错误对象中的错误描述字段名 | string | 'desc' |

使用方式

import { PolyvRequest } from '@polyv/request-core';
import { StatusCodeRequestPlugin } from '@polyv/request-plugin-status-code';

// 基础用法
const requester = new PolyvRequest({
  requestPlugins: [
    new StatusCodeRequestPlugin(),
  ]
});

// 自定义成功状态码
const requester = new PolyvRequest({
  requestPlugins: [
    new StatusCodeRequestPlugin({
      successCode: [200, 0],
    }),
  ]
});

// 自定义字段名
const requester = new PolyvRequest({
  requestPlugins: [
    new StatusCodeRequestPlugin({
      fields: {
        codeField: 'errorCode',
        dataField: 'result',
        messageField: 'msg',
      },
    }),
  ]
});

// 添加错误处理回调
const requester = new PolyvRequest({
  requestPlugins: [
    new StatusCodeRequestPlugin({
      errorCallback: (code, message) => {
        console.error(`请求失败: ${code} - ${message}`);
      },
    }),
  ]
});

interface PeopleInfo {
  name: string;
}
// 如果后端接口返回的 Response:{ code: 200, data: { name: string } }
const data = await requester.get<PeopleInfo>('/api/data', {});
// 此时无需做 code 判断,直接得到 data 的内容
console.log('名称', data.name);

// 如果你想在某个请求中不使用状态码判断
requester.get('/api/data', {}, {
  useStatusCode: false,
});

响应处理逻辑

  1. 插件会解析接口返回的数据,提取 code、status、message、data 等字段
  2. 当满足以下条件之一时,请求被视为成功:
    • 返回的 code 值在成功状态码列表中
    • 返回的 status 值为 'success'
  3. 成功时直接返回 data 字段的内容
  4. 失败时抛出错误,错误信息包含:
    • code: 优先使用 error.code 字段,其次使用顶层 code 字段
    • message: 优先使用 error.desc 字段,其次使用顶层 message 字段,都不存在则为 '未知错误'
