Pairing

API 參考

將此裝置與已發現的 peer 配對，以便兩者可以透過 LAN / Wi-Fi Aware 交換加密聊天訊息和檔案。配對必須在雙方確認——在此呼叫 pairDevice，然後讓遠端裝置呼叫 respondToPairing。

型別定義

bash

input PairingDeviceInput {
  id: String!                 # remote device id (from discovery)
  name: String!               # remote display name
  ips: [String!]              # known IP addresses
  port: Int!                  # remote HTTP port
  deviceType: DeviceType!     # PHONE | TABLET | DESKTOP | WEB | ...
  version: String!
  platform: String!
  lastSeen: String!           # ISO 8601
  discoveryMethods: [String!] # LAN | AWARE | BLE | ...
}

input PairingRequestInput {
  fromId: String!
  fromName: String!
  port: Int!
  deviceType: DeviceType!
  ecdhPublicKey: String!      # base64 ECDH public key for key exchange
  signaturePublicKey: String! # base64 Ed25519 signing key
  timestamp: Long!            # request creation time (millis)
  ips: [String!]
  signature: String           # signature over the request body
  fromIp: String
  isQrInitiated: Boolean      # true when triggered by QR scan
  awareSupported: Boolean     # remote supports Wi-Fi Aware
}

enum DeviceType { PHONE TABLET DESKTOP WEB OTHER }

操作

mutation

pairDevice

發起與已發現 LAN 裝置的配對。向遠端裝置傳送配對請求；遠端裝置必須透過 respondToPairing 接受，然後才能建立安全通道。

bash

mutation PairDevice($input: PairingDeviceInput!) {
  pairDevice(input: $input)
}

mutation

cancelPairing

取消由本裝置發起的進行中的配對。傳入發現掃描傳回的遠端 deviceId。

bash

mutation CancelPairing($deviceId: String!) {
  cancelPairing(deviceId: $deviceId)
}

mutation

respondToPairing

回應傳入的配對請求——接受（true）或拒絕（false）。接受時，裝置衍生共享 ECDH 金鑰並註冊 peer 以進行加密聊天。

bash

mutation RespondToPairing($input: PairingRequestInput!, $accepted: Boolean!) {
  respondToPairing(input: $input, accepted: $accepted)
}
