我应该如何格式化POST数据以测试Express API端点? [英] How should I format my POST data for testing an express API endpoint?

问题描述

我正在关注: https://www.digitalocean.com/community/tutorials/getting-started-with-mern-stack .

我想测试使用express构建的API端点.我想测试POST.

I would like to test an API endpoint built using express. I would like to test POST.

节点服务器正在运行，我正在使用邮递员检查端点是否正常工作.

The node server is running and I am using postman to check if the endpoint is working.

我不清楚如何格式化帖子数据，发送后的POST请求会导致错误.

I am unclear on how to format the post data and my POST requests result in errors when I send them.

我的API在下面:

const express = require ('express');
const router = express.Router();
const Todo = require('../models/todo');

router.get('/todos', (req, res, next) => {

  //this will return all the data, exposing only the id and action field to the client
  Todo.find({}, 'action')
    .then(data => res.json(data))
    .catch(next)
});

router.post('/todos', (req, res, next) => {
  if(req.body.action){
    Todo.create(req.body)
      .then(data => res.json(data))
      .catch(next)
  }else {
    res.json({
      error: "The input field is empty"
    })
  }
});

router.delete('/todos/:id', (req, res, next) => {
  Todo.findOneAndDelete({"_id": req.params.id})
    .then(data => res.json(data))
    .catch(next)
})

module.exports = router;

我的架构如下:

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

//create schema for todo
const TodoSchema = new Schema({
  action: {
    type: String,
    required: [true, 'The todo text field is required']
  }
})

//create model for todo
const Todo = mongoose.model('todo', TodoSchema);

module.exports = Todo;

在邮递员中，我的网址是"http://localhost:5000/api/todos"并且我要添加一个主体，其键为"action"(动作)值是"asdf".发送后，我得到以下结果:

In Postman, my URL is "http://localhost:5000/api/todos" and I am adding a body with the key as "action" and the value as "asdf". On send I get the following result:

{
    "error": "The input field is empty"
}

能否让我知道如何格式化我的身体数据，以便我可以正确地测试POST端点?

Could you please let me know how to format my body data so that I can test my POST endpoint properly?

推荐答案

1. 打开邮递员，选择请求"为POST，然后单击正文".

1. Open Postman, select request as POST and click on Body.

在正文"下，选择原始"，然后将数据插入下面的空白处，然后从文本更改为JSON选项:-

Under Body, select raw and insert your data in the space below like this and change from text to JSON option:-

{"action":"asdf"；}

{ "action":"asdf" }

请确保在任何路由处理程序之前将其添加到您的app.js文件中

Please make sure to add this to your app.js file before any route handler

const app = express();app.use(express.json());

const app = express(); app.use(express.json());
