Как разместить и проанализировать данные для экспресс-узла

Question

Я пытаюсь отправить этот json в конечную точку экспресса узла

    {
        "horizontalAlignment": "center"
    },
    {
        "horizontalAlignment": "center"
    }
]
 }

Он не анализируется правильно в экспрессе, и я пытаюсь выяснить, что нужно.Я попробовал несколько разных вещей.

Я установил парсер тела и применил его глобально

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

это ничего не изменило.

* POST от клиента

    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())
}

Я попытался настроить модель, которая была автоматически сгенерирована для этого API.

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

Это повлияло на результат, но не помоглопроблема.Вот результат, который я получаю

const model = mongoose.model('CreateExcel', createExcelSchema)

export const schema = model.schema

Хорошо, я собираюсь предположить, что вы не публикуете JSON в URL-адресе, что означает применение

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

Не очень вам поможет.Скорее всего, вам понадобится промежуточное программное обеспечение json , которое будет анализировать тело

app.use(bodyParser.json())

в формате JSON.
