I need to be able to use the http request body in my request proxy application and then again in the actual web service. I am using restreamer to 'reset' the stream (and even wrote the middleware myself with no change). The web service receives the body just fine, but because end is never emitted, I cannot continue with the request.
Testing with postman, sending a raw body, with content type set. Any suggestions would be greatly appreciated. Thanks!
var express = require('express')
, bodyParser = require('body-parser')
, http = require('http')
, restreamer = require('connect-restreamer')
, httpProxy = require('http-proxy')
var app = express();
app.use(function (req, res, next) {
var body = '';
req.on('data', function (chunk) {
body += chunk.toString('utf8');
});
req.on('end', function (chunk) {
req.body = JSON.parse(body)
next();
});
});
app.use(restreamer());
var proxy = httpProxy.createServer();
app.all('*', function (req, res) {
proxy.web(req, res, {
target: 'http://localhost:8001'
});
});
http.createServer(app).listen(8000);
app2 = express();
app2.use(function (req, res, next) {
var body = '';
req.on('data', function (chunk) {
body += chunk.toString('utf8');
});
req.on('end', function (chunk) {
req.body = JSON.parse(body)
next();
});
});
app2.all('*', function (req, res) {
res.send(req.body)
});
http.createServer(app2).listen(8001);
Using the request library in my application, it worked:
var request = require('request')
request.post({
url: 'http://localhost:8000',
json: {content: 123, type: "greeting", access_token: "here i am"}
},function(err, res,data){
console.log('return:' ,err, data)
});
But using curl with a file containing the same message, it would not work:
curl -X POST -d @data.json http://localhost:8000 --header "Content-Type:application/json"
I compared the request objects against each other and found a few differences and when I got to the request header for content-length, I found that editing it the "correct" length would end the steam (and the web server would send a response).
I will make the modifications needed and commit to connect-restreamer module.
