于是我就以我原有的思維認(rèn)為,這b肯定是我自己的代碼寫錯(cuò)了。∮谑,開始了我那痛苦的一天,我代碼一個(gè)一個(gè)排查,最后快崩潰的時(shí)候,上網(wǎng)查了一下,原因居然是:
然后我就想把flask的版本降低,但是想了想,不對(duì)呀,這樣更加吃虧了呀,我很多插件是基于flask的2.3.2版本的呀,很難受那時(shí)候,然后吃了個(gè)飯,想了想,要不修改一下源代碼?說干就干,開始了我一下午的網(wǎng)絡(luò)查找答案的過程,
最后還是靠chatgpt幫我修改了源代碼,功夫不負(fù)有心人,最后成功解決。!
復(fù)制一下代碼覆蓋上去:

A function to dynamically create a new MongoEngineJSONEncoder class
