在 NodeJS 中从 Axios 请求接收 JSON

Question

我正在尝试在 NodeJS 中接收我通过 axios 发布请求发送的 JSON，但我不知道如何接收该 JSON 以及如何读取它。 Axios 发布请求由一个 url 发出，该 url 从带有表单操作的 html 页面接收数据，然后 axios 向应该接收该 JSON 并在页面上打印的第二个 url 发出 post 请求。我该怎么办？

谢谢

更新：现在我不知道为什么 Axios 没有找到它必须发布的 url，它响应错误 404

HTML:

<p id="demo"></p>
<p id="demo1"></p>
<p id="demo2"></p>
<p id="demo3"></p>

Actions :
<input type = "text" list = "actions" name = "action">
  <datalist id = "actions">
  <option value="Create"></option>
  <option value="Update"></option>
  <option value="Delete"></option>
</datalist>

<br>
<br>

Type :
<input type = "text" list = "types" name = "type">
  <datalist id = "types">
  <option value="Person"></option>
  <option value="Companies"></option>
  <option value="Opportunities"></option>
  <option value="Lead"></option>
  <option value="Projects"></option>
  <option value="Tasks"></option>
  <option value="Activities"></option>
</datalist>

<br>

ID: <input type="text" id="demo" name="id">
    <br>
    <br>
ID1: <input type="text" id="demo1" name="id1">       
    <br>
    <br>
Subscription ID: <input type="text"  id="demo2" name="subid">
    <br>
    <br>
Old Name: <input type="text"  id="demo3" name="oname">
    <br>
    <br>
New Name: <input type="text"  id="demo4" name="nname">
    <br>
    <br>
<input type="submit"  value="Submit"> 

</form>

使 Axios POST 的 NodeJS

exports.notification = (req, res) => {

var express = require('express');

var axios = require('axios');

var https = require('https');

var bodyParser = require('body-parser');

var app = express();



var config = {

 path : '/',

 headers: {'Content-Type' : 'application/x-www-form-urlencoded',

 'Content-Type' : 'text/html',

 'Content-Type' : 'application/json' }

};



var info = {

 ids:[req.body.id,req.body.id1],

 type: req.body.type,

 event: req.body.action,

 subscription_id: req.body.subid,

 secret_field_1:null,

 secret_field_2:null,

 updated_attributes:{field_name:[req.body.oname,req.body.nname]}

}  



var myJSON = JSON.stringify(info);



return axios.post('/notification-example', info, config)

 .then((result) => {

   console.log("DONE",result);

 })

 .catch((err) => {

   console.log("ERROR",err);

 })
};

接收并打印 JSON 的第二个 url 的 NodeJS

const express = require ('express');
const https = require ('https');
const bodyParser = require ('body-parser');

const app = express();

const port  = 8080;

// ROUTES
var router = express.Router(); // get an instance of router
router.use(function(req, res, next) { // route middleware that will happen on every request
 console.log(req.method, req.url); // log each request to the console
 next(); // continue doing what we were doing and go to the route
});

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

app.use('/notification-example',require ('./Routers/API/notification_example'));

app.use('/', router); // apply the routes to our application

// START THE SERVER
// ==============================================
app.listen(port);
console.log('Listening ' + port);

module.exports={
  app
};

通知文件

const express = require('express');
const router = express.Router();

//const notification_example = require('../../Notification');

router.get('/', function(req, res) {
    ????
});

module.exports = router;

Answer 1

这里发生了很多事情，但如果您将???? 替换为res.body 或res.data，您应该会得到您正在寻找的JSON 数据。
