这个错是跨域问题,网上说是关于http头部的问题 让改成https 但是不适合我这个错
这个主要就是后端接收和前端的数据类型存在差距的原因
前端

let  p2 = this.formInline.pName||undefined
axios({
                    url:'http://localhost:8081/product/searchnumcha',
                    method:'get',
                    params:{
                        pCate:p1,
                        pName:p2,
                        pPrice:p3,
                        pJianjie: p4,
                    },

                }).then(({data})=>{
                        this.allpro = data;
                        console.log(this.tabledatel.pCate)
                    }
                )

p2是个多选 是个数组类型
后端

@RequestParam(value = "pName") String name

这边需要是List 进行接收
否则就会出错 改成List name就行
