我正在尝试将此json发布到节点Express端点

 }

在express中没有正确解析它，我正在尝试找出需要什么。我尝试了几种不同的方法。

我安装了body解析器并将其全局应用

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

没有任何改变。

*来自客户端的POST

    const _fetch = model => {
  return fetch(`http://0.0.0.0:9000/create-excels`, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json; charset=utf-8'
    },
    body: JSON.stringify(model)
  }).then(statusHelper).then(response => response.json())
}

我尝试调整为此API自动生成的模型。

 const createExcelSchema = new Schema({
  data: {
    type: [[]] // Array
  },
  colWidths: {
    type: Array
  },
  colStyles: {
    type: [{}] // Array
  }
}, {
  timestamps: true,
  toJSON: {
    virtuals: true,
    transform: (obj, ret) => { delete ret._id }
  }
})

这确实影响了结果，但没有解决问题。这是我得到的结果

路线

      import { Router } from 'express'
import { middleware as body } from 'bodymen'
import { create } from './controller'
import { schema } from './model'
export CreateExcel, { schema } from './model'

const router = new Router()
const { data, colWidths, colStyles } = schema.tree

router.post('/',

    import mongoose, { Schema } from 'mongoose'

好吧，我假设您没有在URL中发布JSON，这意味着应用

app.use(bodyParser.urlencoded({ ... }))

不会真正帮助您。您最可能需要的是json中间件，它将解析JSON格式的 body

app.use(bodyParser.json())

如何将数据发布和解析到节点快递
