Have you tried http://localhost:8888/_ah/api/

你试过http：// localhost：8888 / _ah / api /

It seems that the devapiutil takes http://localhost:8888/_ah/api as base url without check and it checks what comes after. / character will tell that's your root.

似乎devapiutil将http：// localhost：8888 / _ah / api作为基本URL而没有检查，它检查后面的内容。 /字符会告诉你这是你的根。
