来自 express 应用程序的 Axios 请求缺少参数

Question

我正在尝试向 FacePlusPlus API 发出 POST 请求。 目前我只是用 node 运行 app.js，但我不断收到错误。

我在 express 应用中的 axios 请求：

axios({
  method: "post",
  url: "https://api-us.faceplusplus.com/facepp/v3/face/analyze",
  headers: {
    'Content-Type': "application/json",
  },
  data: {
    'api_key': '<My api key goes here>',
    'api_secret': '<My api secret goes here>',
    'image_url': 'https://images.pexels.com/photos/220453/pexels-photo-220453.jpeg?w=1260&h=750&auto=compress&cs=tinysrgb'
  }
})
  .then(res => console.log(res))
  .catch(err => console.log(err))

响应错误：

  data: { error_message: 'MISSING_ARGUMENTS: api_key' } } }

数据明明是getting，send，但是为什么会说missing argument呢？

尝试控制台通过响应记录 api-key，看看你得到了什么，因为它告诉你这是一个缺失的参数。你的数据是一个字符串而不是一个对象，应该是这样的，只是出于好奇？
