如何使用node将表单数据（文本/纯文本）转换为json？
[英]How to convert form data (text/plain) to json with node?
问题描述
I need to execute a POST call to an API to placce an order. 
我需要执行对API的POST调用才能放置订单。 Herefore I made a simple Node js app. 因此，我制作了一个简单的Node js应用程序。 At the moment with this current state I receive text/plain data into our app, but this is not in JSON style. 目前处于这种当前状态，我将文本/纯文本数据接收到我们的应用程序中，但这不是JSON样式。
This is what I have now: 这就是我现在所拥有的：
TypeOrder=buy
Coin=BTC
AmountCoin=1
CoinPriceInEuro=100
CoinAddress=17J6W29E2q94YNg5eiaHGsNWW9oJxsWu1M
PaymentMethod=1
GeneralTermsAccepted=true
I want it in JSON (like): 我想要JSON（例如）：
{
"Email": "example1@1.nl",
"Coin": "BTC",
"CouponCode": "",
"AmountEuro": 80.0,
"AmountCoin": 1.0,
"CoinPriceInEuro": 80,
"CoinAddress": "17J6W29E2q94YNg5eiaHGsNWW9oJxsWu1M",
"TypeOrder": "buy",
"PaymentMethod": 1,
"GeneralTermsAccepted": false
}
And attached you find the code. 并附上您找到的代码。
Can anyone tell what I have to do in order to get it in right json? 谁能说出我要做什么才能在正确的json中获得它？
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}); }); });
<!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"> <br> Coin:<br> <input type="text" name="Coin" value="BTC"> Amount in Coin:<br> <input type="number" name="AmountCoin" value="1"> <br> Coin Price in Euro:<br> <input type="number" name="CoinPriceInEuro" value="100"> <br> Coin address to send:<br> <input type="text" name="CoinAddress" value="17J6W29E2q94YNg5eiaHGsNWW9oJxsWu1M"> <br> Payment method:<br> <input type="radio" name="PaymentMethod" value="1" checked> iDeal<br> <input type="radio" name="PaymentMethod" value="2"> Credit Card<br> <input type="radio" name="PaymentMethod" value="3"> PayPal<br> <br> Terms accepted:<br> <input type="radio" name="GeneralTermsAccepted" value="true" checked>Ja<br> <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> </body> </htm

So, you can do something like the following: 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 ];
} );
This is a very simple approach. 这是一个非常简单的方法。 You can make it more functionally oriented or simpler using a tonne of libraries. 您可以使用大量的库使它更加注重功能或更简单。 :) :)

The body data is separated by \\n , so you can split and then loop over that array. 主体数据用\\n分隔，因此您可以拆分然后在该数组上循环。
- The
payload_templateis your empty template that will be filled with the body data.payload_template是您的空模板，将使用主体数据填充该模板。
Snippet 片段
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);

There is no need to specify the enctype as text/plain in your form. 无需在表单中将enctype指定为text / plain。
Just remove that properly since your node app is already using json encoder as a middleware. 只需将其正确删除即可，因为您的节点应用程序已在使用json编码器作为中间件。

what about this: 那这个呢：
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);
