我正在尝试将以下API从Next.js转换为Astro.build:

import type { NextApiRequest, NextApiResponse } from "next";
import prisma from "lib/prisma";

export default async function handler(
  req: NextApiRequest,
  res: NextApiResponse
) {
  try {
    // @ts-ignore
    const slug = req.query.slug.toString();
    const contentType = req.body.contentType;

    if (req.method === "POST") {
      const newOrUpdatedViews = await prisma.view.upsert({
        where: { slug },
        create: {
          slug,
          contentType: contentType,
        },
        update: {
          count: {
            increment: 1,
          },
        },
      });

      return res.status(200).json({
        total: newOrUpdatedViews.count.toString(),
      });
    }

    if (req.method === "GET") {
      const views = await prisma.view.findUnique({
        where: {
          slug,
        },
      });

      // @ts-ignore
      return res.status(200).json({ total: views.count.toString() });
    }
  } catch (e) {
    // @ts-ignore
    return res.status(500).json({ message: e.message });
  }
}

我试着在https://docs.astro.build/en/core-concepts/endpoints/的帮助下编辑它，但最终没有结果。到目前为止，API看起来像这样，但我不知道从哪里得到的响应：

import type {APIRoute} from "astro"

export const get: APIRoute = async function get({params, request}) {
  try {
    const slug = request.query.slug.toString()
    const contentType = request.body.contentType

    if (request.method === "POST") {
      const newOrUpdatedViews = await prisma.view.upsert({
        where: {slug},
        create: {
          slug,
          contentType: contentType,
        },
        update: {
          count: {
            increment: 1,
          },
        },
      })

      return res.status(200).json({
        total: newOrUpdatedViews.count.toString(),
      })
    }

    if (request.method === "GET") {
      const views = await prisma.view.findUnique({
        where: {
          slug,
        },
      })

      // @ts-ignore
      return res.status(200).json({total: views.count.toString()})
    }
  } catch (e) {
    // @ts-ignore
    return res.status(500).json({message: e.message})
  }
}

VS代码告诉我，查询不存在于以下行中：

const slug = request.query.slug.toString()

这一行的contentType也是如此：

const contentType = request.body.contentType

Astro的API会是什么样子？
