使用next-connect v1.0.0-next.4连接MongoDB遇TypeError求助

你的错误是因为next-connect从v1版本开始改用命名导出，不再提供默认导出，原来的import nc from "next-connect"写法会导致nc是undefined，调用nc()就触发is not a function错误。

直接按下面的步骤修改代码即可：

1. 修改导入语句，使用命名导入createRouter：

import DbConnect from "@/utilis/DbConnect";
import { createRouter } from "next-connect"; // 替换原来的import nc from "next-connect"
import Service from "@/models/Service";

2. 用createRouter()替代原来的nc()初始化路由：

const handler = createRouter();

修改后的完整代码：

import DbConnect from "@/utilis/DbConnect";
import { createRouter } from "next-connect";
import Service from "@/models/Service";
 

DbConnect();

const handler = createRouter();

handler.get(async (req, res) => {
  try {
    const services = await Service.find({});
    res.status(200).json(services);
  } catch (error) {
    res.status(500).json({ message: "Error fetching services" });
  }
});

handler.post(async (req, res) => {
  const { title, details, isActive } = req.body;

  const newService = new Service({ title, details, isActive });

  try {
    await newService.save();
    res.status(201).json({ message: "Service added successfully" });
  } catch (error) {
    res.status(500).json({ message: "Error adding service" });
  }
});

export default handler;

补充：next-connect v1版本还有部分API调整，比如全局错误处理需要通过createRouter({ onError: ... })配置，但你当前的接口逻辑用上面的修改就能解决问题。
