经过反复的尝试之后，很明显，这个标准 import jwt from 'jsonwebtoken' 不起作用，谷歌使用自己的编码npm库- google-auth-library ，请在此查看更多。基本解决方案如下：

const { OAuth2Client } = require('google-auth-library')

/**
 * @description Function to decode Google OAuth token
 * @param token: string
 * @returns ticket objet
 */
export const getDecodedOAuthJwtGoogle = async token => {

  const CLIENT_ID_GOOGLE = 'yourGoogleClientId'

  try {
    const client = new OAuth2Client(CLIENT_ID_GOOGLE)

    const ticket = await client.verifyIdToken({
      idToken: token,
      audience: CLIENT_ID_GOOGLE,
    })

    return ticket
  } catch (error) {
    return { status: 500, data: error }
  }
}

用法：

getDecodedOAuthJwtGoogle(credential) // credentials === JWT token

如果您的令牌（凭证）有效，则希望返回如下内容：

{
  // These six fields are included in all Google ID Tokens.
  "iss": "https://accounts.google.com",
  "sub": "110169484474386276334",
