So I deployed a nodeJS script on GAE and whenever I hit a POST endpoint I
get a 502 Bad Gateway error. The endpoint is a simple service that grabs a
screenshot of a page using phantomJS and returns a JSON that contains the
base64 representation of the image in it.
Doing a GET to this endpoint works fine and returns a healthy 200 response,
however as soon as I try a POST request I get: **502 Bad Gateway**
Here is my **app.yaml**:
service: pdf-service
# [START runtime]
runtime: nodejs
vm: true
# [END runtime]
threadsafe: yes
# Temporary setting to keep gcloud from uploading node_modules
skip_files:
- ^node_modules$
handlers:
- url: (.*)/
script: app.js
secure: always
My **app.js** script:
'use strict';
var express = require('express');
var app = express();
var cors = require('cors');
var bodyParser = require('body-parser')
var phantom = require('./phantom');
app.use(cors());
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))
var tmpURL = 'https://www.google.com';
// [START hello_world]
// Say hello!
app.post('/', function(req, res) {
console.log('requrl', req.body);
phantom.takeScreenShot(tmpURL, res);
});
app.get('/', function(req, res) {
res.status(200).send({'greetings': 'Hello World'});
});
// [END hello_world]
if (module === require.main) {
// [START server]
// Start the server
var server = app.listen(process.env.PORT || 8080, function() {
var host = server.address().address;
var port = server.address().port;
console.log('App listening at http://%s:%s', host, port);
});
// [END server]
}
module.exports = app;
Notes:
**The code works on my local environment.**
