我试图调用Spotify API，它与curl配合得很好，但当我尝试在NestJS应用程序中使用axios时，我得到了一个错误。
下面是“curl”命令，它可以工作并返回我的访问令牌：

curl -X "POST" "https://accounts.spotify.com/api/token" \
-d "grant_type=authorization_code" \
-d "code={MY_AUTHORIZATION_CODE}" \
-d "redirect_uri={MY_REDIRECT_URI}" \
-d "client_id={MY_CLIENT_ID}" \
-d "client_secret={MY_CLIENT_SECRET}" \
-d "scope=user-library-read"

response : 
{"access_token":"{MY_ACCESS_TOKEN}","token_type":"Bearer","expires_in":3600,"refresh_token":"{MY_REFRESH_TOKEN}","scope":"user-library-read"}

字符串
我试着把它转换成这样一个axios请求：

@Get('liked-songs')
  async getLikedSongs(@Query('code') code: string) {
    console.log('code : ', code);
    let accessToken;
    const CLIENT_ID = '{MY_CLIENT_ID}';
    const CLIENT_SECRET = '{MY_CLIENT_SECRET}';
    const REDIRECT_URI = '{MY_REDIRECT_URI}';

    const requestBody = {
      grant_type: 'authorization_code',
      code: code,
      redirect_uri: REDIRECT_URI,
      client_id: CLIENT_ID,
      client_secret: CLIENT_SECRET,
      scope: 'user-library-read',
    };

    axios
      .post('https://accounts.spotify.com/api/token', requestBody)
      .then((response) => {
        console.log('Access token:', response.data.access_token);
        accessToken = response.data.access_token;
      })
      .catch((error) => {
        console.error('Error fetching access token:', error);
      });
  }

所以我的代码在我的控制台中正确显示，但我有这个错误：
