Can we modify fs.readFileSync(__dirname + '/game.php'); to fs.readFileSync(__dirname + '/game.php?id='+id); ?
It gives me an error:
fs.js:549 return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
Is there any other way?
I suppose you're trying to do a GET call to your php service, which runs on its own (like you have a webserver which provides php pages on localhost/game.php or similar).
If this is the case, you need to use the http library, and I think something like this can work for you:
"use strict";
var http = require("http");
var id = 123;
var options = {
host: "localhost",
port: 80,
path: 'game.php?id=' + id,
method: "GET"
};
var req = http.request(options, function(res) {
console.log("STATUS: " + res.statusCode);
console.log("HEADERS: " + JSON.stringify(res.headers));
res.on("data", function (chunk) {
console.log("BODY: " + chunk);
});
});
req.end();

Client function is requesting for data from Server. I imported this function in other file where I need it to use. It is working fine. But i don't understand why I am receiving on command prompt "Undefined". I have commented all console.log but still it is coming. I'm not sure if export/import has problem?
Here is my code:
// tstReq.js
function getData(iccid) {
toString(iccid);
var http = require('http');
var jasParseData;
var options = {
host: 'demo8620001.mockable.io',
port: 80,
path: '/Api3',
method: 'get'
};
http.request(options, function(res) {
//console.log('STATUS: ' + res.statusCode);
//console.log('HEADERS: ' + JSON.stringify(res.headers));
res.setEncoding('utf8');
res.on('data', function (chunk) {
//console.log('BODY: ' + chunk);
josParseData= JSON.parse(chunk);
for(i = 0, len = Object.keys(josParseData.iccid[i]).length; i<=len; i++) {
//console.log('JSON.parse:',josParseData.iccid[i]);
//console.log("iccid: ",iccid);
if (josParseData.iccid[i] === iccid) { // Only printed match iccid
console.log('JSON.parse:',josParseData.iccid[i]);
console.log("iccid: ",iccid);
}
if (josParseData.iccid[i] === iccid) {
console.log("Valid Jasper", i+1);
console.log('\n');
}
else{
// console.log ("Invlid Jasper");
}
//console.log('\n');
}
//console.log('\n');
});
}).end();
};
module.exports = getData;
Here is code where I am using exported function:
const fs = require('fs');
var parse = require('csv-parse');
var validateICCID = require('./funcValidateId.js');
var getData = require('./tstReq.js');
fs.createReadStream('iccid2.csv')
.pipe(parse({delimiter: ':'}))
.on('data',function(csv) {
csvrow= csv.toString();
console.log('\n');
console.log(getData(csvrow));
console.log('\n');
});
You're probably getting undefined because the function getData doesn't have a return statement. It doesn't mean your function is broken, it's just not directly returning a result.
If you want to log the result of getData, you'll need to return http.request, and you'll need to resolve the http.request by returning in the callback.
Also, I noticed you declared var jasParseData you probably meant josParseData.
All,
Thanks for taking a moment to check out this question. Any help is appreciated as I'm a beginner.
I am trying to work with Node.js to make a SOAP/AXL call over to a v11.5 Cisco Callmanager. I have copied the code from this person blog which has a really awesome explanation: http://blog.darrenparkinson.uk/2014/04/accessing-cisco-administrative-xml-axl.html
I have verified that the user has AXL permissions and that the AXL service is enabled on the CAllmanager. I am able to successfully run the same SOAP/AXL call against the same Callmanager with the same credentials using SoapUI successfully.
However, when I run this I get an http.599 error back. I've got a funny feeling it has something to do with the security, but I can't put my finger on it.
Here is my code.
var https = require("https");
var authentication = 'username:password';
var headers = {
'SoapAction':'CUCM:DB ver=11.5',
'Authorization': 'Basic ' + new Buffer(authentication).toString('base64'),
'Content-Type': 'text/xml; charset=utf-8'
}
var soapBody = new Buffer('<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:axl="http://www.cisco.com/AXL/API/11.5">' +
'<soapenv:Header/>' +
'<soapenv:Body>' +
'<ns:listCss sequence="?">' +
'<searchCriteria>' +
'<name>%</name>' +
'</searchCriteria>' +
'<returnedTags uuid="?">' +
'<name>?</name>' +
'<description>?</description>' +
'<clause>?</clause>' +
'</returnedTags>' +
'</ns:listCss>' +
'</soapenv:Body>' +
'</soapenv:Envelope>');
var options = {
host: '192.168.204.10', // The IP Address of the Communications Manager Server
port: 8443, // Clearly port 443 for SSL -- I think it's the default so could be removed
path: '/axl/', // This is the URL for accessing axl on the server
method: 'POST', // AXL Requires POST messages
headers: headers, // using the headers we specified earlier
rejectUnauthorized: false // required to accept self-signed certificate
};
// Doesn't seem to need this line, but it might be useful anyway for pooling?
options.agent = new https.Agent(options);
var req = https.request(options, function(res) {
console.log("status code = ", res.statusCode);
console.log("headers = " , res.headers);
res.setEncoding('utf8');
res.on('data', function(d) {
console.log("Got Data: " + d);
});
});
req.write(soapBody);
req.end();
req.on('error', function(e) {
console.error(e);
});
I was able to get your code working by making the following two changes:
line 5, AXL is picky about the format of the SOAPAction value:
'SOAPAction':'"CUCM:DB ver=11.5 listCss"',
line 10, the XML namespace defined in the envelope ('axl') was not consistent with the namespace used in the request ('ns')
var soapBody = new Buffer('<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.cisco.com/AXL/API/11.5">' +
I'm sending an http request using the http.request function, and I would like to read the whole http response like text; that is, the raw http protocol text. Is it possible? I've written the below code but it's not working.
// Set up the request
console.log('Sending request');
var post_req = http.request(post_options, function(res) {
res.setEncoding('utf8');
console.log('Response statusCode: ' + res.statusCode);
// res.on('data', function (chunk) {
// console.log('Response: ' + chunk);
// });
// res.on('end', function() {});
});
post_req.on('socket', function (socket) {
var response = "";
socket.on('data', function(chunk){
console.log(chunk);
});
});
// post the data
post_req.write(post_data);
post_req.end();
If you want access to the raw http message, I'd suggest using the net module instead, and writing the request yourself. Something like this for a simple GET request:
var net = require('net');
var host = 'stackoverflow.com',
port = 80,
socket = net.connect(port, host, function() {
var request = "GET / HTTP/1.1\r\nHost: " + host + "\r\n\r\n",
rawResponse = "";
// send http request:
socket.end(request);
// assume utf-8 encoding:
socket.setEncoding('utf-8');
// collect raw http message:
socket.on('data', function(chunk) {
rawResponse += chunk;
});
socket.on('end', function(){
console.log(rawResponse);
});
});
For a POST request sending application/x-www-form-urlencoded data, you could write the request using something like:
function writePOSTRequest (data, host, path) {
return "POST " + path + " HTTP/1.1\r\n" +
"Host: " + host + "\r\n" +
"Content-Type: application/x-www-form-urlencoded\r\n" +
"Content-Length: " + Buffer.byteLength(data) + "\r\n\r\n" +
data + "\r\n\r\n";
}
var data = "name1=value1&name2=value2",
request = writePOSTRequest(data, host, "/path/to/resource");
where I'm using Buffer.byteLength because Content-Length requires the length in bytes, not in characters. Also, remember that data must be URL encoded.
If you don't know much about the format of HTTP messages, then this is a decent place to start:
http://jmarshall.com/easy/http/
Also, if you don't know what the encoding of the response will be then you'll have to parse the headers first to find out, but UTF-8 is by far the most common so it's a pretty safe bet.
Streams2 and Streams1 not always able to inter-operate well, see "problem: streams1 and streams2 duality" in this video.
I tried to listen data at a bit lower level than streams and this code prints raw http response with headers for me:
var http = require('http');
var raw = '';
console.log('Sending request');
var req = http.request({host: 'stackoverflow.com'}, function(res) {
watch(res, 'res');
res.on('end', function() {
console.log(raw);
});
res.on('data', function(data) {
// if we don't attach 'data' handler here 'end' is not called
});
});
req.on('socket', function (socket) {
socket.resume();
var oldOndata = socket.ondata;
socket.ondata = function(buf, start, end) {
raw += buf.slice(start, end).toString();
oldOndata.call(socket, buf, start, end);
};
});
req.end();
Assuming these kind of tools are allowed in your environment, you could run up an HTTP debug proxy such as Fiddler http://www.fiddler2.com/, which enables you to inspect the HTTP calls and responses.
I know this is probably Asynchronous Javascript 101 and I do have some books on the Kindle I could consult, but I am nowhere near my device.
I have a node app with a variable being assigned to a module that I'm loading. The module has one function that downloads a string of data from a URL.
The problem is, how do I not set the variable until the request has returned?
My code looks like this:
Downloader.js:
var http = require('http');
exports.downloadString = function(str) {
console.log("Downloading from " + str);
http.get(str, function(res) {
var data = [];
console.log("Got response: " + res.statusCode);
res.on('data', function (chunk) {
data.push(chunk);
});
res.on('end', function() {
return data.join('');
});
}).on('error', function(e) {
console.log("Got error: " + e.message);
});
}
app.js:
var downloader = require('./lib/Downloader')
, dateParser = require('./lib/DateParser')
, eventIdGenerator = require('./lib/EventIdGenerator');
var report = downloader.downloadString("http://exampleapi.com");
console.log(report);
I need to wait until the variable named "report" is populated.
Obviously this means my Mocha tests are also failing as I'm still unsure of how to tell the test to wait until the variable is filled.
I'm sure this is extremely simple, but I am drawing a blank!
Thanks!
Node.js is (mostly) asynchronous, so you'd need to pass a callback function to your module:
Downloader.js:
var http = require('http');
exports.downloadString = function(str, callback) {
console.log("Downloading from " + str);
http.get(str, function(res) {
var data = [];
console.log("Got response: " + res.statusCode);
res.on('data', function (chunk) {
data.push(chunk);
});
res.on('end', function() {
callback(data.join(''));
});
}).on('error', function(e) {
console.log("Got error: " + e.message);
});
};
app.js:
var downloader = require('./lib/Downloader')
, dateParser = require('./lib/DateParser')
, eventIdGenerator = require('./lib/EventIdGenerator');
downloader.downloadString("http://exampleapi.com", function(report) {
console.log(report);
});
How could I send POST request with data (eg. some variables) to the https server and display the results to the end user?
Use the http.Client module. From the docs:
var http = require('http');
var google = http.createClient(80, 'www.google.com');
var request = google.request('GET', '/', {'host': 'www.google.com'});
request.end();
request.on('response', function (response) {
console.log('STATUS: ' + response.statusCode);
console.log('HEADERS: ' + JSON.stringify(response.headers));
response.setEncoding('utf8');
response.on('data', function (chunk) {
console.log('BODY: ' + chunk);
});
});
I am pretty sure that you can exchange GET with POST ;)
