Q: 我想用 NodeJS 寫一個 HTTP Server

A:

Q: 我想在 127.0.0.1 的伺服器端建立 /todos 的路徑，在 get 指令時會回傳 todos 物件的資料，post 指令時會將資料加入 todos 物件，也需要 delete 指令去刪除特定 id 的資料，關於 id 的部分，我想使用 uuid 模組，最後，我會需要 patch 指令去修改特定 id 的資料

A:

const http = require("http");
const { v4: uuidv4 } = require("uuid");

const hostname = "127.0.0.1";
const port = 3000;

const todos = {};

const server = http.createServer((req, res) => {
  const { method, url } = req;

  if (url === "/todos") {
    switch (method) {
      case "GET":
        res.setHeader("Content-Type", "application/json");
        res.end(JSON.stringify(todos));
        break;
      case "POST":
        let body = "";
        req.on("data", (chunk) => {
          body += chunk.toString();
        });
        req.on("end", () => {
          const id = uuidv4();
          const todo = JSON.parse(body);
          todos[id] = todo;
          res.statusCode = 201;
          res.setHeader("Content-Type", "application/json");
          res.end(JSON.stringify({ id, ...todo }));
        });
        break;
      case "DELETE":
        const deleteId = url.split("/")[2];
        delete todos[deleteId];
        res.statusCode = 204;
        res.end();
        break;
      case "PATCH":
        let patchBody = "";
        req.on("data", (chunk) => {
          patchBody += chunk.toString();
        });
        req.on("end", () => {
          const patchId = url.split("/")[2];
          const patchData = JSON.parse(patchBody);
          todos[patchId] = { ...todos[patchId], ...patchData };
          res.statusCode = 200;
          res.setHeader("Content-Type", "application/json");
          res.end(JSON.stringify(todos[patchId]));
        });
        break;
      default:
        res.statusCode = 405;
        res.end();
        break;
    }
  } else {
    res.statusCode = 404;
    res.end();
  }
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

Q: 請幫我加上 handleError.js 來去處理常見的錯誤狀況與輸入檢查

A:

handleError.js
