Question

我需要对API执行POST调用以安排订单。因此我制作了一个简单的Node js应用程序。目前这个状态我收到文本/普通数据到我们的应用程序，但这不是JSON风格。

这就是我现在所拥有的：

TypeOrder=buy
Coin=BTC
AmountCoin=1
CoinPriceInEuro=100
CoinAddress=17J6W29E2q94YNg5eiaHGsNWW9oJxsWu1M
PaymentMethod=1
GeneralTermsAccepted=true

我想用JSON（比如）：

{
  "Email": "example1@1.nl",
  "Coin": "BTC",
  "CouponCode": "",
  "AmountEuro": 80.0,
  "AmountCoin": 1.0,
   "CoinPriceInEuro": 80,
  "CoinAddress": "17J6W29E2q94YNg5eiaHGsNWW9oJxsWu1M",
  "TypeOrder": "buy",
  "PaymentMethod": 1,
  "GeneralTermsAccepted": false
}

并附上你找到的代码。

任何人都可以告诉我必须做什么才能在正确的json中获得它吗？

＆＃13;

const express = require('express');
const http = require('http');
const app = express();
const fs=require('fs');
const hostname = '127.0.0.1';
const port = 3000;
const bodyParser = require('body-parser');
var jsonParser = bodyParser.json()
var urlencodedParser = bodyParser.urlencoded({ extended: false })

fs.readFile('index.html', (err, html) => {
	if(err) {
	    throw err;
	}

	var server = http.createServer((req, res) => {
	    res.statusCode=200;
	    res.setHeader('Content-type', 'text/html');
	    res.write(html);
	    res.end();
	});

	server.listen(port, hostname, () => {
	    console.log('Server started on port'+port);
	});

	// POST /login gets urlencoded bodies
        app.post('http://localhost:3030/rest/v1/PostOrder', urlencodedParser, function (req, res) {
            console.log(req.body);
            if (!req.body) return res.sendStatus(400);
            res.send('http://localhost:3030/rest/v1/PostOrder', {qs:req.query});
        });
});

＆＃13;

<!DOCTYPE html>
<html>
<body>

<form enctype="text/plain" action="http://localhost:3030/rest/v1/PostOrder" method="POST">
  Buy/Sell:<br>
  <input type="text" name="TypeOrder" value="buy">

  Coin Price in Euro:<br>

  <br>
  Coin address to send:<br>
  <input type="text" name="CoinAddress" value="17J6W29E2q94YNg5eiaHGsNWW9oJxsWu1M">

  <input type="radio" name="GeneralTermsAccepted" value="false">No<br>
  <br><br>


  <input type="submit" value="Submit">
</form>

<p>If you click the "Submit" button, the form-data will be sent to a page called "/action_page.php".</p>

Answer 1

因此，您可以执行以下操作：

const data = `
    TypeOrder=buy
    Coin=BTC
    AmountCoin=1
    CoinPriceInEuro=100
    CoinAddress=17J6W29E2q94YNg5eiaHGsNWW9oJxsWu1M
    PaymentMethod=1
    GeneralTermsAccepted=true`;

let parts = data.split( '\n' );
let formattedData = {};

parts.forEach( ( part ) => {
    const splitData = part.split( '=' );
    formatterData[ splitData[ 0 ] ] = splitData[ 1 ];
} );

这是一种非常简单的方法。您可以使用大量的库使其更加功能化或更简单。 :)

Answer 2

正文数据由\n分隔，因此您可以拆分然后遍历该数组。

payload_template是您的空模板，将填充正文数据。

<强>段

let body = `TypeOrder=buy
Coin=BTC
AmountCoin=1
CoinPriceInEuro=100
CoinAddress=17J6W29E2q94YNg5eiaHGsNWW9oJxsWu1M
PaymentMethod=1
GeneralTermsAccepted=true`;

let payload = {};
body.split('\n').forEach((c) => [key, payload[key]] = c.split('='));
console.log(payload);

.as-console-wrapper {
  max-height: 100% !important
}

Answer 3

无需在表单中将enctype指定为text / plain。

正确删除它，因为您的节点应用程序已经使用json编码器作为中间件。

Answer 4

怎么样：

let str=`TypeOrder=buy
Coin=BTC
AmountCoin=1
CoinPriceInEuro=100
CoinAddress=17J6W29E2q94YNg5eiaHGsNWW9oJxsWu1M
PaymentMethod=1
GeneralTermsAccepted=false`;

let result=str.split('\n').reduce((re, v) => {
  let key=v.split('=')[0],val=v.split('=')[1];    
    if (val.match(/^\d+\.\d+$|^\d+$/)) {
      val=Number(val);
    }else if(val.match(/^true$/i)){
      val=true;
    }else if(val.match(/^false$/i)){
      val=false;
    }    
    re[key]=val;
    return re;
}, {});

console.log(result);

如何使用节点将表单数据（text / plain）转换为json？
