const chatGoogleTranslateOnAzure = async (req, res) => {
  let { text = '你好', target = 'en', apiKey = 'sk-xxx' } = req.body

  if (apiKey === 'xxx') {
    const [translation] = await translate.translate(text, target)
    res.send({
      code: 200,
      data: {
        text,
        translation,
      },
      message: '成功',
