我正在将请求发送到Ticketmaster Discovery v2 API。我已经使用将API密钥嵌入URL中的方法发送了请求并收到了所需的响应。但是，当我更改代码以使用授权标头而不是将其嵌入URL时，代码将完全停止工作并返回错误。
我是API的新手，Ticketmaster的API文档在身份验证标头的语法方面相对较少，因此，对我的代码进行第二次（更老练）的研究可能有助于发现我的错误。
我很好奇我是否在代码中语法上做错了什么，导致缺少期望的响应。
如果不是我的语法问题，那么我很想听听其他可能发现问题的想法或故障排除方法。
我试图在第一段和第二段代码之间进行尽可能小的更改。除了嵌入式API密钥外，它们似乎都生成相同的URL字符串。因此，我相信我的标头语法可能是罪魁祸首，但是我缺乏确定的REST API经验。

当我运行使用基于标头的身份验证的代码段时，生成的URL字符串如下所示：
https://app.ticketmaster.com/discovery/v2/events?keyword=music&dmaId=366&size=200&radius=2
返回的错误是这样的：
{'fault'：{'faultstring'：'无法解析API密钥变量request.queryparam.apikey'，'detail'：{'errorcode'：'steps.oauth.v2.FailedToResolveAPIKey'}}}
