我正在使用symfony和API平台设置项目，如果我在控制台中运行路由调试器，则可以看到我的新路由：
--------------------------- -------- -------- ------ -------------------------------------
Name Method Scheme Host Path
--------------------------- -------- -------- ------ -------------------------------------
_preview_error ANY ANY ANY /_error/{code}.{_format}
api_entrypoint ANY ANY ANY /api/{index}.{_format}
api_doc ANY ANY ANY /api/docs.{_format}
api_jsonld_context ANY ANY ANY /api/contexts/{shortName}.{_format}
api_users_get_collection GET ANY ANY /api/users.{_format}
api_users_post_collection POST ANY ANY /api/users.{_format}
api_users_get_item GET ANY ANY /api/users/{id}.{_format}
api_users_delete_item DELETE ANY ANY /api/users/{id}.{_format}
api_users_put_item PUT ANY ANY /api/users/{id}.{_format}
api_users_patch_item PATCH ANY ANY /api/users/{id}.{_format}
--------------------------- -------- -------- ------ -------------------------------------
但是，我在浏览器中看不到它们。如果我转到http://localhost，则可以看到symsony4主页；如果我转到http://localhost/api，则将看到“未找到错误”。
这是调试api_entrypoint路由时的输出
