ConnInfo 助手

ConnInfo 助手可以帮助您获取连接信息。例如，您可以轻松地获取客户端的远程地址。

导入

Cloudflare Workers

import { Hono } from 'hono'
import { getConnInfo } from 'hono/cloudflare-workers'

Deno

import { Hono } from 'hono'
import { getConnInfo } from 'hono/deno'

Bun

import { Hono } from 'hono'
import { getConnInfo } from 'hono/bun'

Vercel

import { Hono } from 'hono'
import { getConnInfo } from 'hono/vercel'

Lambda@Edge

import { Hono } from 'hono'
import { getConnInfo } from 'hono/lambda-edge'

Node.js

import { Hono } from 'hono'
import { getConnInfo } from '@hono/node-server/conninfo'

用法

const app = new Hono()

app.get('/', (c) => {
  const info = getConnInfo(c) // info is `ConnInfo`
  return c.text(`Your remote address is ${info.remote.address}`)
})

类型定义

从 getConnInfo() 获取的值的类型定义如下

type AddressType = 'IPv6' | 'IPv4' | undefined

type NetAddrInfo = {
  /**
   * Transport protocol type
   */
  transport?: 'tcp' | 'udp'
  /**
   * Transport port number
   */
  port?: number

  address?: string
  addressType?: AddressType
} & (
  | {
      /**
       * Host name such as IP Addr
       */
      address: string

      /**
       * Host name type
       */
      addressType: AddressType
    }
  | {}
)

/**
 * HTTP Connection information
 */
interface ConnInfo {
  /**
   * Remote information
   */
  remote: NetAddrInfo
}
