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 🙏

AuthorizeAppSignRequestPlugin

用途:应用签名授权插件,使用后会在所有请求中插入应用签名信息。

实例化参数

| 参数名 | 用途 | 类型 | 默认值 | | ----------------- | ---------------------- | ----------------- | --------------------- | | appId | 应用 ID | string | - | | appSecret | 应用密钥 | string | - | | signatureNonce | 是否使用防重放 | boolean | false | | signatureMethod | 签名方式 | SignatureMethod | SignatureMethod.MD5 | | getAppSign | 获取应用签名信息的方法 | function | - |

请求选项

| 参数名 | 用途 | 类型 | 默认值 | | ----------------- | -------------------- | ----------------- | ------ | | useAppSign | 是否使用应用签名授权 | boolean | true | | signatureNonce | 是否使用防重放 | boolean | - | | signatureMethod | 签名方式 | SignatureMethod | - |

应用签名信息类型

AppSignData 类型如下:

| 参数名 | 用途 | 类型 | 默认值 | | ----------------- | ------------ | ----------------- | ------ | | appId | 应用 ID | string | - | | timestamp | 签名的时间戳 | number | - | | sign | 签名 | string | - | | signatureMethod | 签名方式 | SignatureMethod | - |

使用方式

import { PolyvRequest, SignatureMethod } from '@polyv/request-core';
import { AuthorizeAppSignRequestPlugin } from '@polyv/request-plugin-authorize-app-sign';

// 方式一:直接传入应用 ID 和密钥
const requester = new PolyvRequest({
  requestPlugins: [
    new AuthorizeAppSignRequestPlugin({
      appId: 'yourAppId',
      appSecret: 'yourAppSecret',
      signatureMethod: SignatureMethod.MD5,
    }),
  ],
});

// 方式二(推荐):自定义获取应用签名信息的方法
const requester = new PolyvRequest({
  requestPlugins: [
    new AuthorizeAppSignRequestPlugin({
      getAppSign: async ({ params, signatureMethod }) => {
        // 可以在这里实现自定义的签名逻辑
        return {
          appId: 'yourAppId',
          timestamp: Date.now(),
          sign: 'yourGeneratedSign',
          signatureMethod,
        };
      },
    }),
  ],
});

// 使用防重放机制
const requester = new PolyvRequest({
  requestPlugins: [
    new AuthorizeAppSignRequestPlugin({
      appId: 'yourAppId',
      appSecret: 'yourAppSecret',
      signatureNonce: true,
    }),
  ],
});

// 如果你想在某个请求中使用不同的签名方式
requester.get(
  '/api/data',
  {},
  {
    signatureMethod: SignatureMethod.SHA256,
  },
);

// 如果你想在某个请求中不使用应用签名授权
requester.get(
  '/api/data',
  {},
  {
    useAppSign: false,
  },
);

签名处理逻辑

  1. 插件会自动在请求中添加以下参数:

    • appId: 应用 ID
    • timestamp: 当前时间戳
    • sign: 根据参数生成的签名
    • signatureMethod: 签名方式(可选)
    • signatureNonce: 防重放随机字符串(当启用防重放时)
  2. 签名生成逻辑有两种方式:

    • 通过传入的 appId 和 appSecret 自动生成
    • 通过自定义的 getAppSign 方法生成
  3. 当启用防重放机制时,每次请求会生成一个唯一的 signatureNonce 参数,用于防止请求被重放攻击
