TypeError:解析器不是``next connect`中的函数

Question

我有一个使用next-connect和twitter-api-v2的项目。

我有一个调用2个get路由的handler，如下所示：

export default handler()
  .get('/twitter/generate-auth-link', generateAuthLink)
  .get('/twitter/get-verifier-token', getVerifierToken)

handler如下所示：

import { NextApiResponse } from 'next'
import cookieSession from 'cookie-session'
import nc from 'next-connect'
import { ironSession } from 'next-iron-session'
import { error } from 'next/dist/build/output/log'
import { NextIronRequest } from '../types/index'

const COOKIE_SECRET = process.env.COOKIE_SECRET
const SESSION_SECRET = process.env.SESSION_SECRET

const IS_PRODUCTION = process.env.NODE_ENV !== 'development'

/**
 * Create an API route handler with next-connect and all the necessary middlewares
 *
 * @example
 * ```ts
 * export default handler().get((req, res) => { ... })
 * ```
 */
function handler() {
  if (!COOKIE_SECRET || !SESSION_SECRET)
    throw new Error(
      `Please add COOKIE_SECRET & SESSION_SECRET to your .env.local file!`
    )

  return nc<NextIronRequest, NextApiResponse>({
    onError: (err, _, res) => {
      error(err)
      res.status(500).end(err.toString())
    },
  })
    .use(
      cookieSession({
        name: 'session',
        keys: [COOKIE_SECRET],
        maxAge: 24 * 60 * 60 * 1000 * 30,
        secure: IS_PRODUCTION && !process.env.INSECURE_AUTH,
        signed: IS_PRODUCTION && !process.env.INSECURE_AUTH,
      })
    )
    .use(
      ironSession({
        cookieName: 'mysite-session',
        password: SESSION_SECRET,
        // if your localhost is served on http:// then disable the secure flag
        cookieOptions: {
          secure: IS_PRODUCTION,
        },
      })
    )
}

export default handler

我认为我在做next-connect是正确的，但是为什么当我尝试在客户机上执行简单的fetch时会出现错误，比如：

const res = await fetch('/api/twitter/generate-auth-link');
console.log({res})

后台给出如下错误：

  page: '/api/twitter/generate-auth-link'
}

我已经做了一个完整的复制品https://github.com/deadcoder0904/twitter-api-v2-3-legged-login-using-next-connect→

我想做的就是使用twitter-api-v2执行3条腿的Oauth步骤。在https://github.com/PLhery/node-twitter-api-v2/blob/master/doc/auth.md上给出了步骤

我该如何解决这个问题？

Answer 1

我从pages/api/twitter/中删除了index.ts文件，并在pages/api/twitter/generate-auth-link和pages/api/twitter/get-verifier-token中使用了默认导出。

这解决了这个问题！
