本地Docker API拦截异常及HTTP-Toolkit相关问题咨询

我在本地端口9000运行了一个Docker API服务器，通过Node客户端使用POST请求调用该API。开启HTTP-Toolkit拦截后，它成功创建了另一个容器，并添加如下代理环境变量重启了API容器：

遇到的问题 #

• 不修改客户端fetch调用时，HTTP-Toolkit无任何拦截记录，但API服务器可正常响应Node客户端请求；
• 将fetch调用改为http://locahost:8000/my-api时，浏览器控制台出现来自该地址的CORS问题，拦截记录显示2条500错误；未实现的GET请求还抛出错误：Error: Passthrough loop detected. This probably means you're sending a request directly to a passthrough endpoint, which is forwarding it to the target URL, which is a passthrough endpoint, which is forwarding it to the target URL, which is a passthrough endpoint.

疑问与需求 #

• 据我理解无需将请求端口改为8000，但不清楚拦截失败的原因，是否有更手动的方式设置透传？
• 关闭HTTP-Toolkit时它会删除API容器，能否阻止该行为？
