I want to request a simple JSON File in NodeJS. With Javascript and jQuery it works like a charm:
$(document).ready(function() {
$.getJSON('https://www.younow.com/php/api/broadcast/info/curId=0/user=Peter', function(json) {
if (json["errorCode"] > 0) {
console.log("Offline");
$('#ampel').addClass('red');
} else {
console.log("Online");
$('#ampel').addClass('green');
}
});
})
But i can't get it to work with NodeJS:
var request = require('request');
var options = {
url: 'https://www.younow.com/php/api/broadcast/info/curId=0/user=Peter',
headers: {
'content-type': 'application/javascript'
}
};
function callback(error, response, body) {
console.log(response.statusCode);
}
request(options, callback);
The StatusCode is always 403 and i can't work with the data. Can somebody help me, so i can get the same result like with jQuery?
Thanks!
I was able to find the solution with Mike McCaughan's help:
I had to send a different user-agent to get a 200 response. The code looks like this now:
var options = {
url: 'https://www.younow.com/php/api/broadcast/info/curId=0/user=',
headers: {
'User-Agent': 'request'
}
};
function callback(error, response, body) {
var str = JSON.parse(body);
if (str.errorCode > 0) {
...
} else {
...
}
}
request(options, callback);

As the uri is generated is as expected and list data is shown in page but while sending the req in request method, 500 error occurs instead of retruning body.
uri: http://yufluyuinnepal.com/?vTRIPTYPE=O&vOPSID=O&vSTRFROM=KTM&vSTRFROMTXT=&vSTRTO=PKR&vSTRTOTXT=&vFLIGHTDATE=27-Nov-2018&vRETURNDATE=27-Nov-2018&vADULT=1&vCHILD=0&vNATIONALITY=NP&vNATIONALITYTXT=Nepal&
const uri = `http://yufluyuinnepal.com/?${queryString(query)}`;
console.log(uri);
const req = {
uri: uri,
};
request(req, (error, response, body) => {
if (error) {
return reject(error);
}
if (response.statusCode !== 200) {
return reject(new Error(`Expected 200 but got ${response.statusCode}`));
}
return resolve(body);
});
Let me know how can i return body and what is wrong in my code.
In Request npm module, specify what kind of request is it (GET/POST etc)
// Example GET Request
var options = {
method: "GET",
url:
uri,
headers:
{
// headers as per documentation
}
};
request(options, (error, response, body) => {
if(error){}
if(response.statusCode !== 200){}
return resolve(body);
})
This is your current implementation with a callback function.
const req = {
uri: uri,
method: 'GET'/'POST'
};
request(req, (error, response, body) => {
if (error) {
console.log(error);
}
if (response.statusCode !== 200) {
//Do something
}
console.log(body);
//Do something
});
When using request-promise module you should write something like this
var rp = require('request-promise');
const req = {
uri: uri,
method: 'GET'/'POST'
}
rp(req)
.then((res) => {
//Do something
})
.catch((error) => {
//Do something with error
});
Please try this
let requestp=require('request-promise');
var options = {
method: 'POST',
url: 'uri',
resolveWithFullResponse: true,
headers: {
'Accept': 'application/json',
'Content-Type' : 'application/json'
},
body: TextedValue
};
await requestp(options).then(async function(Content){
await requestp(options).then(async function(response){
if (await response.statusCode == 200)
{
console.log(Content); // in ur case it is body
}
else
{
console.log("Response code "+response.statusCode+" .Try Again Later")
}
})
})
I'm looking to purge Cloudflare's cache through its API. More specially, the purge all files command.
However, I keep running into the "Invalid Content-Type header, valid values are application/json,multipart/form-data" error message, despite explicitly setting the Content-Type header with Node.js' request package.
What am I missing?
var request = require('request');
gulp.task('cfPurge', function() {
var options = {
url: 'https://api.cloudflare.com/client/v4/zones/myZoneID/purge_cache',
headers: {
'X-Auth-Email': 'email',
'X-Auth-Key': 'myAPIkey',
'Content-Type': 'application/json'
},
form: {
'purge_everything': true,
}
};
function callback(error, response, body) {
var resp = JSON.parse(body);
if (!error & response.statusCode == 200) {
console.log('CF Purge: ', resp.success);
}
else {
console.log('Error: ', resp.errors);
for (var i = 0; i < resp.errors.length; i++)
console.log(' ', resp.errors[i]);
console.log('Message: ', resp.messages);
console.log('Result: ', resp.result);
}
}
return request.post(options, callback);
});
Output:
Error: [ { code: 6003,
message: 'Invalid request headers',
error_chain: [ [Object] ] } ]
{ code: 6003,
message: 'Invalid request headers',
error_chain:
[ { code: 6105,
message: 'Invalid Content-Type header, valid values are application/json,multipart/form-data' } ] }
Message: []
Result: null
According to the documentation for the cloudfare API, you need to send an HTTP DELETE request and not an HTTP POST request:
Modify the line...
return request.post(options, callback);
...with:
return request.del(options, callback);
Also, this is not a form. You need to put the JSON in the body of the data. So, replace the block...
form: {
'purge_everything': true,
}
...with:
body: JSON.stringify({'purge_everything': true})
I have the following code, it creates a file on a remote server from a test var (just to make sure it worked), but now I need to upload a file and I'm not sure how to actually attach it to the request, here is the code:
var dataString = '#test.txt';
var options = {
uri: 'https://site.zendesk.com/api/v2/uploads.json?filename=test.txt',
method: 'POST',
headers: {
'Content-Type': 'application/binary',
'Accept': 'application/json',
Authorization: 'Basic bXVydGV6LmF....'
},
body: dataString
//this will create a test file with some text, but I need
//to upload a file on my machine instead
}
function callback(error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body);
}
var x = {
error: error,
response: response,
body: body
}
console.log(x);
}
request(options, callback);
I was thinking something in the lines of:
fs.createReadStream('text.txt').pipe({function?})
But I'm not sure how to finish this part unfortunately.
update: 2019
It's been a LONG time, but someone asked for the solution. I'm not sure if this is how I fixed it tbh or if this code even works, but I found this digging around, give it a try.
Also, Zendesk updated their API at some point, not sure when exactly so this may be old anyways:
var uploadAttachment = function() {
var uOptions = {
uri: 'xxx/api/v2/uploads.json?filename=' + fileName,
method: 'POST',
headers: {
'Content-Type': 'application/binary',
'Accept': 'application/json',
Authorization: 'Basic xxx'
}
};
function callback(error, response, body) {
if (!body) {
if (error) {
return next(error);
} else {
var x = {
error: true,
message: "Some message",
err: response
};
return next(x);
}
}
if (body && body.error) {
return next(error);
}
if (error) {
return next(error);
}
var jr = JSON.parse(body);
var uploaded = {};
if (jr.upload) {
uploaded = jr.upload;
}
attachToComment(uploaded);
}
fs.createReadStream(tempPath + fileName).pipe(request(uOptions, callback));
};
I hope this helps, sorry in advance if it does not work, I no longer have access to zendesk.

This is the api code I to which I need to make the GET and POST request. But I have no idea how to do it.
It looks like your code is using express which would normally be good for building and API for your app. However to make a simple request to a third party api and staying in node.js why not try the request module which is great. https://www.npmjs.org/package/request
Your example does not show what the path of the request is or if you need any additinal headers etc but here is a simple example of a GET request using request.
var request = require('request');
function makeCall (callback) {
// here we make a call using request module
request.get(
{ uri: 'THEPATHAND ENDPOINT YOU REQUEST,
json: true,
headers: {
'Content-Type' : 'application/x-www-form-urlencoded',
}
},
function (error, res, object) {
if (error) { return callback(error); }
if (res.statusCode != 200 ) {
return callback('statusCode');
}
callback(null, object);
}
);
}
or jquery .ajax from a front end client direcct to your path
$.ajax({
url: "pathtoyourdata",
type: "GET",
})
.done(function (data) {
//stuff with your data
});
I write application by phonegap
Server Side I write by nodejs
exports.login = function(request, response) {
var keys = Object.keys(request.query);
request.body= JSON.parse(keys[1]);
Accounts.findOne({
name : request.body.name
}, function(err, docs) {
if (!docs) {
response.json('{"error": "user-not-found"}');
} else {
console.log("docs: ", docs);
Accounts.validatePassword(request.body.password, docs['hashedPass'], docs['salt'], function(error, res) {
if (error) {
response.json(error);
}
if (res) {
generateToken(request.body.name, request.body.device, function(res) {
if (res) {
response.json('{"token": "' + res + '"}');
} else {
response.json('{"error": "cant-create-token"}');
}
});
} else {
response.json('{"error": "invalid-password"}');
}
});
}
})
}
Phonegap: I write function to login
function LoginUser(info)
{
var varUrl=server+"/auth/login";
$.ajax({
url:varUrl,
type:"GET",
contentType:"application/json",
headers: {
Accept:"application/json",
"Access-Control-Allow-Origin": "*"
},
data:info,
dataType:"jsonp",
success:function(data)
{
console.log("HERE");
console.log(data);
},
error: function(err){
console.log(err);
}
});
}
and I request it will like this http://localhost:3000/auth/login?callback=jQuery161014894121675752103_1361459462241&{%22name%22:%22fdfdfd%22,%22password%22:%22fdfdfdfd%22}&_=1361459615743
and when I see in the response of tab network of developer of chrome is "{\"error\": \"user-not-found\"}"
but I can not catch this repsonse in function LoginUser(info) above
How to get it because in console it print error: function(err){
console.log(err);
}
I dont know why.
Can you help me.
On the server side you have to use callback and in the response of your
jsonp file you need to do:
jQuery161014894121675752103_1361459462241({"error": "user-not-found"})
Where the function name comes from the callback variable in your jsonp request.
Cause a jsonp request just "include" a script tag in your site, which can execute js (basically).
