当我将数据库寄存器推送到 Json-server 到 users.json 时，我做错了什么？我有 404 未找到
What did I do wrong when I push database registers to Json-server to users.json. I have 404 not found
我是 ReactJs 编码的新手，我看过一些关于假 JSON-Server 的视频，但我不知道如何 post 来自 register.js 的所有数据到我的“users.json”到“server.js”。
我所做的是编辑 "package.json" "script": "auth": "node server.js" 和 npm i json-server, npm i json-server jsonwebtoken body-parser --save-dew and npm 运行 auth to 运行 server.js
我在 youtube 上学到了这个...
这是我的源代码。有人可以解决我的错误“post”，谢谢！
