[英]How do I make a post request with a JSON payload to an external API using node?
I am trying to make a POST request with a JSON payload to an external API using node. 我正在尝试使用节点向外部API发出带有JSON有效负载的POST请求。
Here is my code: 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();
});
The JSON payload comes through as expected from the origin. JSON有效负载如预期般从来源通过。 However I am unable to forward this payload to the external API.
但是,我无法将此有效载荷转发到外部API。 'request.write(req.body)' appears to be the way to do this, however the external API is still receiving a null payload.
'request.write(req.body)'似乎是实现此目的的方法,但是外部API仍在接收空有效负载。
Any help would be appreciated. 任何帮助,将不胜感激。 Thanks.
谢谢。
Try this Inside the app.post block 在app.post块内尝试
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();
