我正在尝试 MySQL 到 Node.js 中的 post 数据，但无法做到这一点，因为我找不到错误

Question

我已经完成了获取日期和删除数据的工作，但是在发布数据时，我遇到了这个错误。我已经尝试了很多时间，但找不到。我正在使用 Postman 来发布数据。我正面临这个问题，:

code: 'ER_PARSE_ERROR',
errno: 1064,
sqlMessage: "You have an error in your SQL syntax; check the manual that 
corresponds to your MariaDB server version for the right syntax to use near '= 
`name` = 'african', `tagline` = 'black', `description` = 'asthetic', `image...' 
at line 1",
sqlState: '42000',
 index: 0,"

这是我的代码

 const express= require('express')
 const bodyParser=require('body-parser')
 const mysql=require('mysql')

 const app= express()
 const port=process.env.PORT || 5000


 app.use(bodyParser.urlencoded({extended:false}))

app.use(bodyParser.json())

//mysql
const pool=mysql.createPool({

 connectionLimit:10,
 host           :'localhost',
 user           :'root',
 password       :'',
 database       :'nodejs_beers'

})

  //Get All beers
  app.get('',(req,res)=>{

    pool.getConnection((err,connection)=>{

        if(err) throw err
        console.log(`connected as id ${connection.threadID}`)

        connection.query('SELECT * from beers',(err,rows)=>{

            connection.release()

            if(!err){
                res.send(rows)
            }
            else{
                console.log(err)

            }
        })

       })


   })

    //Get All beers
   app.get('/:id',(req,res)=>{

    pool.getConnection((err,connection)=>{

        if(err) throw err
        console.log(`connected as id ${connection.threadID}`)

        connection.query('SELECT * from beers WHERE id=?',[req.params.id],(err,rows)=>{

            connection.release()

            if(!err){
                res.send(rows)
            }
            else{
                console.log(err)

            }
        })

      })


   })

   //delete A beer by id
    app.delete('/:id',(req,res)=>{

      pool.getConnection((err,connection)=>{

        if(err) throw err
        console.log(`connected as id ${connection.threadID}`)

        connection.query('DELETE from beers WHERE id = ?',[req.params.id],(err,rows)=>{

            connection.release()

            if(!err){
                res.send(`Beer with the id ${[req.params.id]} has been deleted`)
            }
            else{
                console.log(err)

            }
        })

      })


   })

   //Inser A beer 
   app.post('',(req,res)=>{

    pool.getConnection((err,connection)=>{

        if(err) throw err
        console.log(`connected as id ${connection.threadID}`)
        const params=req.body

        connection.query('INSERT INTO beers SET = ?',params,(err,rows)=>{

            connection.release()

            if(!err){
                res.send(`Beer with the id: ${params.id} has been added`)
            }
            else{
                console.log(err)

            }
        })

        console.log(req.body)

       })


    })







    //listen on environment port
 app.listen(port,()=>console.log('listen on port  $(port)'))

Answer 1

您的 INSERT INTO... SET... 语法有点不对劲。您在不应该出现的地方包含了 =（除非您可以 link 到另有说明的权威来源）。

相反，您的 INSERT 查询应该看起来更像：

connection.query('INSERT INTO beers SET ?',params,(err,rows)=>{ // ...
