我正在尝试接收refresh_token我的 Ionic 应用程序，我成功接收了access_token.
我从我的 TypeScript 项目中的端点接收code（authorization_code或access_token）https://accounts.spotify.com/authorize?client_id=，我将它传递cURL给测试如何获取refresh_token但唯一收到错误的东西。
curl -H "Content-Type: application/x-www-form-urlencoded" -H "Authorization: Basic MzBhNT...ZWIyZWQ=" -d grant_type=authorization_code -d code=BQAjgZOFne3p8PB4ARJkrXtq...kI4xJvhQ7SutZoJqVWILCY -d redirect_uri=http%3A%2F%2Flocalhost%3A8100%2Fmain -X POST https://accounts.spotify.com/api/token
预期输出：
{
"access_token": "NgCXRK...MzYjw",
"token_type": "Bearer",
"scope": ...,
"expires_in": 3600,
"refresh_token": "NgAagA...Um_SHo"
}
但收到错误：
{"error":"invalid_grant","error_description":"Invalid authorization code"}
