var decipher = crypto.createDecipheriv('aes-128-cbc', Buffer.from(sessionKey, 'base64'), iv);
你好，麻烦通过点击下方“反馈信息”按钮，提供出现问题的。
decodePhoneNumber(encryptedData: string, key: string, iv: string): string {
const sessionKeyBuffer = Buffer.from(key, 'base64')
const encryptedDataBuffer = Buffer.from(encryptedData, 'base64')
const ivBuffer = Buffer.from(iv, 'base64')
const decipher = crypto.createDecipheriv(
'aes-128-cbc',
sessionKeyBuffer,
ivBuffer,
)
decipher.setAutoPadding(true)
let decoded = decipher.update(encryptedDataBuffer, 'base64', 'utf8')
decoded += decipher.final('utf8')
// fix: 之前即时写的代码忘记转json对象了
const decodedData: { phoneNumber: string } = JSON.parse(decoded)
return decodedData.phoneNumber
}
