AssertionError when trying to POST with bearer auth

从 httpie/cli/argparser.py 中的 _guess_method() 开始，使用报告中的 POST 命令和 traceback 重现 AssertionError。跟踪 bearer-auth 参数和 URL 的解析过程，然后验证无效调用会产生有用的错误消息，而不是 assertion failure。

Expected result

Probably an error message telling me what is wrong about the invocation and how to do it correctly. I'm new to httpie and guess that I did something wrong but I don't know what. https --help is telling me that the method parameter comes directly after the https command but maybe the problem is that the url is in the wrong place and httpie gets confused due to the auth parameters?

Debug output

Please re-run the command with --debug, then copy the entire command & output and paste both below:
