说明

这是一个客户端库,在其中之一查找DIS:

• 使用 /fetch 的 OIDF 注册 ? 子= oidf 端点以查看已完成的, 将其传递为“ sub” 参数的值
• 以DCC以前使用的格式编码的DDs的静态列表 成员和社区注册, 并公开服务, 像这个: https://github.com/digitalcreditis/dcc-community-registry/registry.json 互联网档案馆的存檔,存档日期2013-12-22

请注意,个人在多个登记册中可以出现。 因为这样, 页:1 顺序 登记事项。 例如,提供一份登记册清单:

const knownRegistries = [
  {
    type: 'oidf',
    fetchEndpoint: 'https://registry.dcconsortium.org/fetch?sub=',
    name: 'DCC Member Registry'
  },
  {
    name: 'DCC Sandbox Registry',
    url: 'https://digitalcredentials.github.io/sandbox-registry/registry.json',
    type: 'dcc-legacy'
  }
]

如果两个登记处都包含一个签发人Did,则签发人输入 (包含发行人名称和URL)将来自 第一个 登记册, "DCC成员注册".

换言之,核查人和其他执行人必须下令登记 内 从最权威到最少的顺序。 。 。 .

安装

• 建议节点.js 24+.

国家预防机制

通过国家预防机制安装:

npm install @digitalcredentials/issuer-registry-client

发展

这个项目使用 小时本地安装(用于 发展:

git clone https://github.com/digitalcredentials/issuer-registry-client.git
cd issuer-registry-client
pnpm install

构建、提供和测试:

pnpm run build         # compile to dist/ via tsc
pnpm run lint          # eslint
pnpm run test-node     # vitest (Node)
pnpm run test-browser  # playwright (browser); run `pnpm exec playwright install chromium` first
pnpm test              # fix + lint + node + browser

使用量

您需要一系列已知的 发行人和核查人注册 核对,例如公开的DCC已知登记册副本:

https://digitalcreditifics.github.io/dcc-有名-registries/有名-did-registries.json 互联网档案馆的存檔,存档日期2013-12-22

截至2025年4月22日,情况如此(为方便起见,在此转载):

[
  {
    "type": "oidf",
    "fetchEndpoint": "https://registry.dcconsortium.org/fetch?sub=",
    "name": "DCC Member Registry"
  },
  {
    "type": "dcc-legacy",
    "name": "DCC Sandbox Registry",
    "url": "https://digitalcredentials.github.io/sandbox-registry/registry.json"
  },
  {
    "type": "dcc-legacy",
    "name": "DCC Community Registry",
    "url": "https://digitalcredentials.github.io/community-registry/registry.json"
  },
  {
    "type": "dcc-legacy",
    "name": "MSP Registry",
    "url": "https://sandbox-issuer.myskillspocket.com/registry.json"
  }
]

你用这个列表:

import { RegistryClient } from '@digitalcredentials/issuer-registry-client'

const registryClient = new RegistryClient()

// get the list of known issuers from wherever you store it, which could just be in a variable,
// but here we show how to fetch the DCC's list from it's github repository:
const response = await fetch("https://digitalcredentials.github.io/dcc-known-registries/known-did-registries.json");
const knownRegistries = await response.json();

// set the registry client to use that list
await registryClient.use({ registries: knownRegistries })

// You can now query to see if a DID is known in any registry
const results = registryClient.lookupIssuersFor('did:key:z6MkpLDL3RoAoMRTwTgo3rs39ZwssfaPKtGdZw7AGRN7CK4W'))

查询返回 :

• 已登记所提供DAD的发行人名单
• 任何登记册的清单(来自所提供的已知发行人名单) 选中

每个返回的发行商包括发行商的元数据,以及发行商的元数据 签发人登记的登记处.

供应你自己 fetch

每一个登记请求都通过 globalThis.fetch 默认。 传出 a fetch 自己来接手 - 应用超时,添加信头,服务 从缓存中获取,或到达一个登记册,运行时间不能直接请求(在 浏览器, 一个不发送 CORS 信头的浏览器, 否则会返回 uncheckedRegistries数字 :

const registryClient = new RegistryClient({
  fetch: async url =>
    await fetch(`https://gateway.example/fetch?url=${encodeURIComponent(url)}`)
})

它被称为 URL并返回 a Response完全一样 fetch。 。 。 .

注意,它被称为客户的一种方法, 所以一个赤裸裸的全球参考 - { fetch } 或者说 { fetch: globalThis.fetch } - 这是一个独立的呼叫。 在浏览器中 抛出 TypeError: Illegal invocation,每个注册都回来 uncheckedRegistries如上所举,将其包起来,或将其捆绑起来:

const registryClient = new RegistryClient({
  fetch: globalThis.fetch.bind(globalThis)
})

以下是一个保存在一个遗产中的 DD 的搜索回复 注册,一个OIDF注册, 并列出一个无法检查的注册 由于某种原因(例如,服务器已关闭) :
