Question

我正在尝试使用节点将带有JSON有效负载的POST请求发送到外部API。

这是我的代码：

var express = require('express');
var bodyParser = require('body-parser');
var cors = require('cors');
var url = require("url");
var http = require("http");

var app = express();

app.use(cors());
app.use(bodyParser.urlencoded({ extended: false }));

app.post('/api', function(req, res) {
  var query = url.parse(req.url, true).query;
  var key = query.key;

  console.log('JSON PAYLOAD:');
  console.log(req.body); **//PAYLOAD COMES THROUGH AS EXPECTED**

  var options = {};

  options = {
    host: 'localhost',
    port: 1234,
    method: 'POST',
    headers: {'Content-Type': 'application/json'},
    path: '/api?key=1234'
  };

  var request = http.request(options, function(response) {
    response.setEncoding('utf-8');
    var responseString = '';
    response.on('data', function(data) {
      responseString += data;
    });
    response.on('end', function() {
      var resultObject = JSON.parse(responseString);
      res.json(resultObject);
    });
  });

  request.on('error', function(e) {
  });

  request.write(req.body) **//THIS METHOD SHOULD BE FORWARDING THE PAYLOAD BUT THIS IS NOT THE CASE...**
  request.end();
});

JSON有效负载按照预期从原点开始。但是，我无法将此有效负载转发到外部API。＆＃39; request.write（req.body）＆＃39;似乎是这样做的方式，但是外部API仍然接收空的有效负载。

任何帮助将不胜感激。感谢。

在app.post块中试试这个

var options = {
  host: 'localhost',
  path: '/api?key=1234',
  port: 1234,
  method: 'POST',
  headers: {'Content-Type': 'application/json'}
};

callback = function(response) {
  var str = ''
  response.on('data', function (chunk) {
    str += chunk;
  });

  response.on('end', function () {
    console.log(str);
  });
}

var req = http.request(options, callback);

req.write(JSON.stringify(req.body));
req.end();

如何使用节点将带有JSON有效负载的发布请求发送到外部API？
