【问题描述】：
根据QuickBooks Ruby API documentation，它提供了一个使用curl向步骤1中获得的授权url提交POST请求的示例，但在其下方，它显示如果Web应用程序不支持浏览器，使用 Playground 或 Web 组件。
我的问题是——真的可以使用示例中所示的 curl 命令吗？如果我采用确切的 URL 并尝试建立 POST 请求，我会得到以下结果：
bash-3.2$ curl -X POST "https://appcenter.intuit.com/connect/oauth2?client_id=[redacted]&redirect_uri=http%3A%2F%2Flocalhost&response_type=code&scope=com.intuit.quickbooks.accounting&state=be17472c59724eb46bfe2690"
<html>
<head><title>301 Moved Permanently</title></head>
<body>
<center><h1>301 Moved Permanently</h1></center>
<hr><center>nginx</center>
</body>
</html>
bash-3.2$
显然它正在尝试重定向到另一个 URL，但 API 文档没有显示使用 -L 参数来跟踪重定向。如果我尝试为curl 提供-L 参数以跟踪重定向，则会收到以下响应：
bash-3.2$ curl -X POST "https://appcenter.intuit.com/connect/oauth2?client_id=[redacted]&redirect_uri=http%3A%2F%2Flocalhost&response_type=code&scope=com.intuit.quickbooks.accounting&state=be17472c59724eb46bfe2690" -L
<HTML><HEAD>
<TITLE>Bad Request</TITLE>
</HEAD><BODY>
<H1>Bad Request</H1>
Your browser sent a request that this server could not understand.<P>
Reference #7.2500e8ac.1592267832.14229c52
</BODY>
</HTML>
同样，即使遵循重定向也不起作用。如果我将-I 附加到curl 命令，则会得到以下信息：
bash-3.2$ curl -X POST "https://appcenter.intuit.com/connect/oauth2?client_id=[redacted]&redirect_uri=http%3A%2F%2Flocalhost&response_type=code&scope=com.intuit.quickbooks.accounting&state=be17472c59724eb46bfe2690" -LI

如果我使用相同的 URL 并通过网络浏览器请求它，那么它只会将我带到应有的重定向回调 URL。我不明白为什么curl 没有做同样的事情。如果我什至不能通过 curl 复制相同的东西，我不明白“Web 组件”是什么意思。我还有另一个用于 GET 和 POST 请求的 Web 模块，它们将我带到 HTTP200 但不是回调 URL。
知道如何像在 Web 浏览器中那样从重定向回调 URL 获取此授权令牌吗？这是我尝试通过 Ruby 脚本中的 Web 组件执行此操作的另一个示例：
[3] pry(#<QuickBooksAPI>)> grant_url
=> "https://appcenter.intuit.com/connect/oauth2?client_id=[redacted]&redirect_uri=http%3A%2F%2Flocalhost&response_type=code&scope=com.intuit.quickbooks.accounting&state=be17472c59724eb46bfe2690"
[4] pry(#<QuickBooksAPI>)> response = WebRequest.new.get_request(grant_url)
=> #<Net::HTTPMovedPermanently 301 Moved Permanently readbody=true>
[5] pry(#<QuickBooksAPI>)> response['Location']
=> "https://appcenter.intuit.com/app/connect/oauth2?client_id=[redacted]&redirect_uri=http%3A%2F%2Flocalhost&response_type=code&scope=com.intuit.quickbooks.accounting&state=be17472c59724eb46bfe2690"
[6] pry(#<QuickBooksAPI>)> response = WebRequest.new.get_request(response['Location'])
=> #<Net::HTTPFound 302 Found readbody=true>
[7] pry(#<QuickBooksAPI>)> response['Location']
=> "https://accounts.intuit.com/index.html?partner_uid_button=google&offering_id=Intuit.sbg-fms.ippdevx&redirect_url=https%3A%2F%2Fappcenter.intuit.com%2Fapp%2Fconnect%2Foauth2%3Fclient_id%3D[redacted]%26redirect_uri%3Dhttp%253A%252F%252Flocalhost%26response_type%3Dcode%26scope%3Dcom.intuit.quickbooks.accounting%26state%3Dbe17472c59724eb46bfe2690"
[8] pry(#<QuickBooksAPI>)> response = WebRequest.new.get_request(response['Location'])
=> #<Net::HTTPOK 200 OK readbody=true>
[9] pry(#<QuickBooksAPI>)> response.uri
=> #<URI::HTTPS https://accounts.intuit.com/index.html?partner_uid_button=google&offering_id=Intuit.sbg-fms.ippdevx&redirect_url=https%3A%2F%2Fappcenter.intuit.com%2Fapp%2Fconnect%2Foauth2%3Fclient_id%3D[redacted]%26redirect_uri%3Dhttp%253A%252F%252Flocalhost%26response_type%3Dcode%26scope%3Dcom.intuit.quickbooks.accounting%26state%3Dbe17472c59724eb46bfe2690>
这一次它将我发送到 200，但它实际上从未将我发送到回调/重定向 URL。
我只是简单地尝试完成第 2 步，但似乎没有浏览器就无法完成，即使使用“Web 组件”和 curl。
我是否只需要手动使用 OAuth Playground 并不断刷新我的令牌，因为我的 API 都是后端并且没有前端/用户重定向等？
