Pairing

API 参考

将此设备与已发现的 peer 配对，以便两者可以通过 LAN / Wi-Fi Aware 交换加密聊天消息和文件。配对必须在双方确认——在此调用 pairDevice，然后让远端设备调用 respondToPairing。

类型定义

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

发起与已发现 LAN 设备的配对。向远端设备发送配对请求；远端设备必须通过 respondToPairing 接受，然后才能建立安全通道。

bash

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

mutation

cancelPairing

取消由本设备发起的进行中的配对。传入发现扫描返回的远端 deviceId。

bash

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

mutation

respondToPairing

响应传入的配对请求——接受（true）或拒绝（false）。接受时，设备派生共享 ECDH 密钥并注册 peer 以进行加密聊天。

bash

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