Javascript CouchDB 如何记录或捕获请求对象

文档显示，一个人可以log()a request object toJSON，但它不起作用.

我已经在我的Couch实例上配置了info级日志(log)记录，并精心编制了_design文档来执行此操作，我从"validate_doc_update": "function(doc, req){log(toJSON(req))}"中得到的结果是:

[info] 2023-07-07T21:53:02.138399Z nonode@nohost <0.32001.0> -------- OS Process #Port<0.44> Log :: {"_id":"abc","_rev":"6-4ce6392348c3ad61213d15184a08c3c3","title":"There is Notaasdfhing Left to Lose","artist":"Fasdfoo Fighters","year":"129297","_revisions":{"start":6,"ids":["4ce6392348c3ad61213d15184a08c3c3","558aa6381166ee2836c112e0eac4b148","fa0362e7c84f3c0df7827515b5c58f86","a266c2261a2d0704c5fe7689b6786dfb","645dd6050dcd378678fea4627db832b3","4c6114c65e295552ab1019e2b046b10e"]}}

以下哪项不包括所有记录在请求对象中的好东西？
