我试图将输入数据从 useState 发布到 Mysql，但它没有发生。虽然我能够将数据从数据库获取到页面，但是当涉及到发布时，当有很多值时，我不知道如何将数据从状态挂钩发送到 mysql。 请看一下

我发送表单数据的代码

import React,{useState , useRef} from "react";
import "./AddProjects.css"
import axios from "axios";
import Projects from "../Projects/Projects";
import {BiChevronLeftCircle,BiChevronRightCircle} from "react-icons/bi"

export default function AddProjects() {
    
    
    const [AddProjects,setAddProjects] = useState({
        ProjectName:"",
        Discription:"",
        git:"",
        Img:""
    })


    const [getQuery,setGetQuery] = useState({
        projectList:[]
    })


    const inputFile = useRef(null)


    function handleChange(e) {
        const {name , value} = e.target;
        setAddProjects(newProjects => ({
            ...newProjects,[name]:value
        }))


    }
    function imgChange(e) {
        setAddProjects({ ...AddProjects, Img: URL.createObjectURL(e.target.files[0]) });
    }


    function getProjectList() {
        axios.get(`http://localhost:3060/projects`)
        .then((response) => response.data)
        .then(response2 => {
            setGetQuery({projectList : response2})
        })
    }

    function onSubmitHandler(e) {
        axios.post(`http://localhost:3060/addProjects`,{
                ProjectName: AddProjects.ProjectName,        
                Discription:AddProjects.Discription,
                git:AddProjects.git,
                Img:AddProjects.Img
        })
        getProjectList()
    }
    return(
        <>
            
  
                

                    
Add New Project
                    
                    
                    
                    
                     inputFile.current.click()}>Add New Image
                    Submit Project
                
                click me 
            
            

                

                
My Projects 
                {/*   */}

                

                    
                            

                                {getQuery.projectList.map((gettingQuery) => 
                                    
                                )}
                            
                        
                    
                
            
                 
    )

};

正如你所看到的，我想将 4 件事发送到 mysql 表，但我不认为这是这样做的方法，我只是无法弄清楚

正在发送数据的文件的代码

const express = require('express');
const cors = require('cors')
const PORT = 3060;
const db  = require('./Database')

const bodyParser = require('body-parser');
const { response } = require('express');

const app = express();

app.use(cors());
app.use(bodyParser.json());

app.get('/projects', (req,res) => {
    const TASK_QUERY = `SELECT * FROM  addprojects.newproject`;
    db.query(TASK_QUERY , (err, response) => {
        if(err) res.status(404).send('somthings wrong')
        else res.send(response)
    })
});

app.post('/addProjects', (req,res) => {
    const ADD_QUERY = `INSERT INTO addprojects.newproject VALUES('${req.body.data}')`;
    db.query(ADD_QUERY, (err) => {
        if (err) console.log(err)
        else res.send('Query added sucsessfully')
    })
    
} );

app.listen(PORT, () => {
    console.log('app is listning to port 3000')
})

我认为虽然发布方法是正确的，但价值并不正确，所以请帮助我，我已经为此呆了 2 天任何建议都会有帮助
