Node.js+expressでリクエストボディを取得

Last updated at Posted at 2022-12-18

前回の記事でnodeからmysql接続してデータ登録をしたので今回はAPIリクエストボディにセットした値でデータ登録をするようにします

リクエストボディを取得するコード

npmやyarnで body-parser をインストールしてください
req.body でリクエストボディが取得できます

// リクエストボディ取得準備
const bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({
  extended: true
}));
app.use(bodyParser.json());

/**
 * ユーザー登録
 */
const registerUser = async(userName) => {
  await createConnection()
  const [result, filelds] = await client.query(
    `INSERT INTO users VALUES (0, '${userName}')`
  )
  await client.end()
  return result
}

/**
 * @Controller
 * ユーザー登録API
 */
app.post('/users', async(req, res) => {
  // リクエストボディ.nameプロパティの値を取得
  const result = await registerUser(req.body.name)
  res.send(result ? "ユーザー登録に成功しました" : "ユーザー登録に失敗しました")
})

app.listen(3000)

APIリクエストはこちら

curl --location --request POST 'http://localhost:3000/users' \
--header 'Content-Type: application/json' \
--data-raw '{"name": "operator"}'
