axios封装的post请求,后台返回400问题

Question

用自己封装的axios发送post请求, 后台返回400. 说我参数格式错误

export const questionnaire = (payload) => {

  return request(C.QUESTIONNAIRE,'post',payload,{

    transformRequest: [function (data, headers) {

      headers['Content-Type'] = 'application/x-www-form-urlencoded'

      data = qs.stringify(data)

      return data

    }]

  })

}

点击按钮发送请求

handleClick(index, row) {

        this.idx = index

        this.loading = true

        (this.pidList为数组数据)

        questionnaire({params: this.pidList}).then( result => {

          this.loading = false

          console.log(result)

        })

      },

后台数据格式:

Answer 1

{params: this.pidList}这个东西得改吧。至少也得是{params: {personIds:this.pidList}}

Answer 2

提示字面意思缺少personIds参数，你传的this.pidList的key是个啥？
