NodeJS使用Express框架进行POST请求报“BadRequestError:request aborted”

本文介绍: Nod eJS使用Ex pre ss 框架进行POST请求报“BadReque s tEr ror:request a borte d”

直接说结果吧，跟你是否启用了mock.js有关。

由于我的前端框架采用了VueElementAdmin，这个框架内置了mockJS的模拟数据。所以我默认也采用了这个配置。

下面文章仅供参考。目前而言，在不使用Moc kJS的情况下（尤其是那个mock server.js）,不管怎么配，是不会有问题的。但是一旦混合引入，就会出问题。下面文章仅供参考，关键是你是否引用了mockSe r v e r。

import axios from 'axios'

// 创建axios实例
const service = axios.create({
  baseURL: 'http://127.0.0.1:95', // url = base url + request url
  withCredentials: true, // send cookies when cross-domain requests
  timeout: 5000 // request timeout
})

export default service

const express = require('express')
const server = express()

const startServer = () =&gt; {
  server.use(express.json())
  server.use(express.urlencoded({ extended: true }))

    console.log(req.query)
    resp.send({
      code: 200
