Question

我使用Feathers框架到我的nodejs应用程序，我已经按照以下方式创建了jwt

  app.service('authentication').hooks({
    before: {
      create: [
        authentication.hooks.authenticate(config.strategies),
        function (hook) {
         hook.params.payload = {
            userId: hook.params.user.userId,
            accountId: hook.params.user.accountId
          };
          return Promise.resolve(hook);
        }
      ],
      remove: [
        authentication.hooks.authenticate('jwt')
      ]
    }
  });

现在我怀疑如何使用jwt解码数据从令牌获取userId。

使用jwt-decode lib将在feathersjs中提供jwt解码功能

const decode = require('jwt-decode');

hook.params.headers.authorization =  'eyJhbGciOiJIUzI1NiIsInR5cCI6ImFjY2VzcyIsInR5cGUiOiJhY2Nlc3MifQ.eyJ1c2VySWQiOjEsImFjY291bnRJZCI6MSwiaWF0IjoxNTA2MzMwNzIyLCJleHAiOjE1MDY0MTcxMjIsImF1ZCI6Imh0dHBzOi8veW91cmRvbWFpbi5jb20iLCJpc3MiOiJmZWF0aGVycyIsInN1YiI6ImFub255bW91cyJ9.gZrDJhmzdpt9-7OCeRcKiayQiKbtv-3UaTkN1BhOCAI'

var userId =  decode(hook.params.headers.authorization).userId; 
console.log(userId)

如何解码jwt并从featherjs中获取此userId？
