签名

了解如何签署消息用于身份验证。

签署个人消息

签署任意消息用于身份验证：


const message = new TextEncoder().encode('Hello, Sui!')
const [account] = await provider.getAccounts()
const chain = await provider.getActiveChain()
 
const result = await provider.signPersonalMessage({
  message,
  account,
  chain,
})
 
console.log({
  signature: result.signature,   // Base64 编码的签名
  bytes: result.bytes,           // 已签名的消息字节
})

签署消息（旧版）


const message = new TextEncoder().encode('Hello, Sui!')
const [account] = await provider.getAccounts()
const chain = await provider.getActiveChain()
 
const result = await provider.signMessage({
  message,
  account,
  chain,
})
 
console.log({
  signature: result.signature,
  messageBytes: result.messageBytes,
})

验证签名


import { verifyPersonalMessage } from '@mysten/sui.js/verify'
 
const message = new TextEncoder().encode('Hello, Sui!')
const [account] = await provider.getAccounts()
const chain = await provider.getActiveChain()
const { signature } = await provider.signPersonalMessage({ message, account, chain })
 
const accounts = await provider.getAccounts()
const publicKey = accounts[0].publicKey
 
const isValid = await verifyPersonalMessage(message, signature)
console.log('签名有效:', isValid)

错误处理


try {
  await provider.requestPermissions()
} catch (error) {
  if (error.code === 4001) {
    console.log('用户拒绝了连接请求')
  } else {
    console.error('连接错误:', error.message)
  }
}
