在Node js Rest中发送Post请求

Question

我不能从客户端发送帖子请求!

我需要将中的HTTP请求发送到支付网关。Post请求需要有标题和主体有效负载。我有前端和后端分离，我使用Rest与express.js和支付网关需要服务器到服务器的通信，所以我不能从客户端这样做。基本上，当用户单击支付时，我需要向后端服务器发送呼叫，然后我的后端服务器需要向支付网关发送请求。

支付网关只有MVC ()文档，它们真的帮不上忙。

控制器内部的逻辑应该是这样的

exports.payment = (req, res, next) => {
   const { amount, id, currency } = req.body;

   //add headers
   //create body paloyad

   //send request to https://payment....com/api-key/transaction

   //receive response

   res.status(200).json({ status: 'success' });
}

Answer 1

有几种方法可以实现，比如提取，但是，我更喜欢使用Axios

const axios = require('axios');

exports.payment = (req, res, next) => {
   const { amount, id, currency } = req.body;

   //add headers
   const options = {
      headers: {'X-Custom-Header': 'value'}
   };

   //create body payload
   const body = {
      amount: amount
      id: id
      currency: currency
   };

   //send request to https://payment....com/api-key/transaction
   axios.post('https://payment....com/api-key/transaction', body, options)
      .then((response) => {
        //receive response
        console.log(response);
        res.status(200).json({ status: 'success' });

      })
      .catch((error) => {
        console.log(error)
      });

使用阿西克斯发送POST请求。容易多了。

const axios = require('axios')


let config = {
    headers: {
        header1: value,
    }
}

let data = {
 'amount': amount,
 'id':id,
 'currency':currency,
}


axios.post('https://payment....com/api-key/transaction', data,config)
  .then(function (response) {
    console.log(response);
  })

您可以使用https://github.com/node-fetch/node-fetch

const fetch = require('node-fetch');

const body = {a: 1};

const response = await fetch('https://httpbin.org/post', {
    method: 'post',
    body: JSON.stringify(body),
    headers: {'Content-Type': 'application/json'}
});
const data = await response.json();

console.log(data);
