I am using this API to consume a ESPN API:
http://api.espn.com/v1/now?apikey=d4skkma8kt2ac8tqbusz38w6
In Node.js, using node-curl library, my snippet looks like this:
var Curl = require('node-curl/lib/Curl')
curl.setopt('URL', url);
curl.setopt('CONNECTTIMEOUT', 2);
curl.on('data', function(chunk) {
console.log(chunk);
});
But everytime when I run this code I keep on getting response as:
<h1>596 Service Not Found</h1>
Strange is, same URL if I hit from the browser I get the correct response so URL is not invalid. This happens only if I try to call from Node.js. Can anyone guide me how to resolve this error? I tried encoding/decoding url, still I get same response.
Also basically I am avoiding any vendor specific libraries as much as possible, since we should have generic api calling framework
You could use request, which is a very popular module. Here's an example of how you could do it:
var request = require('request');
var url = 'http://api.espn.com/v1/now?apikey=d4skkma8kt2ac8tqbusz38w6';
request(url, function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(JSON.parse(body));
}
});

var Request = require("request");
Request.get("https://www.yonline.com", (error, response, body) => {
if(error) {
return console.dir(error);
}
document.getElementById('msg').innerHTML=JSON.parse(body)
console.dir(JSON.parse(body));
});
I tried this code, but it is only giving data on the command line. i want it to give data on the intended textfield.
NodeJS is server side script you can't access HTML element like this.
You need to do it on html javascript side.

Please try to install request package using npm and use below code :
var request = require('request');
//Lets try to make a HTTP GET request to modulus.io's website.
request('http://www.modulus.io', function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body); // Show the HTML for the Modulus homepage.
}
});
Below link explains in more detail :

For some reason, I have a problem with "request" module.
var options = {
protocol: "https",
host: "euw.api.pvp.net",
pathname: "/api/lol/euw/v1.4/summoner/by-name/" + name,
search: "api_key=api-key-deleted"
};
var riotURL = url.format(options);
request(riotURL, function (error, response, body) {
if (!error && response.statusCode == 200) {
//doing someting
}
});
And then it goes weird. If name is simple, like "Dager", "hi mom" and so one, my app doing fine. But when I try to put names like "növentaynueve", "Mìnou" - my request return 404 response.
I managed to get full response text: http://pastebin.com/8Vra1i4X. And I can't understand what happened. All links in response are correct. But it looks like request module instead of sending request to
https://euw.api.pvp.net/api/lol/euw/v1.4/summoner/by-name/n%C3%B6ventaynueve?api_key=api-key-deleted
sends request to
https://euw.api.pvp.net/api/lol/euw/v1.4/summoner/by-name/n%EF%BF%BDventaynueve?api_key=api-key-deleted
But why?
Solved problem with encodeURI() function.
And funny thing: on Debian, it works even without encodeURI(). But on Windows 10 not. Both source files are UTF-8.
How to check if youtube video exists on node.js app server side:
var youtubeId = "adase268_";
// pseudo code
youtubeVideoExist = function (youtubeId){
return true; // if youtube video exists
}
You don't need to use the youtube API per-se, you can look for the thumbnail image:
Valid video = 200 - OK:
http://img.youtube.com/vi/gC4j-V585Ug/0.jpg
Invalid video = 404 - Not found:
http://img.youtube.com/vi/gC4j-V58xxx/0.jpg
I thought I could make this work from the browser since you can load images from a third-party site without security problems. But testing it, it's failing to report the 404 as an error, probably because the content body is still a valid image. Since you're using node, you should be able to look at the HTTP response code directly.
I can't think of an approach that doesn't involve making a separate HTTP request to the video link to see if it exists or not unless you know beforehand of a set of video IDs that are inactive,dead, or wrong.
Here's an example of something that might work for you. I can't readily tell if you're using this as a standalone script or as part of a web server. The example below assumes the latter, assuming you call a web server on /video?123videoId and have it respond or do something depending on whether or not the video with that ID exists. It uses Node's request library, which you can install with npm install request:
var request = require('request');
// Your route here. Example on what route may look like if called on /video?id=123videoId
app.get('/video', function(req, response, callback){
var videoId = 'adase268_'; // Could change to something like request.params['id']
request.get('https://www.youtube.com/watch?v='+videoId, function(error, response, body){
if(response.statusCode === 404){
// Video doesn't exist. Do what you need to do here.
}
else{
// Video exists.
// Can handle other HTTP response codes here if you like.
}
});
});
// You could refactor the above to take out the 'request.get()', wrap it in a function
// that takes a callback and re-use in multiple routes, depending on your problem.
#rodrigomartell is on the right track, in that your check function will need to make an HTTP call; however, just checking the youtube.com URL won't work in most cases. You'll get back a 404 if the videoID is a malformed ID (i.e. less than 11 characters or using characters not valid in their scheme), but if it's a properly formed videoID that just happens to not correspond to a video, you'll still get back a 200. It would be better to use an API request, like this (note that it might be easier to use the request-json library instead of just the request library):
request = require('request-json');
var client = request.newClient('https://www.googleapis.com/youtube/v3/');
youtubeVideoExist = function (youtubeId){
var apikey ='YOUR_API_KEY'; // register for a javascript API key at the Google Developer's Console ... https://console.developers.google.com/
client.get('videos/?part=id&id='+youtubeId+'&key='+apikey, function(err, res, body) {
if (body.items.length) {
return true; // if youtube video exists
}
else {
return false;
}
});
};
Using youtube-feeds module. Works fast (~200ms) and no need API_KEY
youtube = require("youtube-feeds");
existsFunc = function(youtubeId, callback) {
youtube.video(youtubeId, function(err, result) {
var exists;
exists = result.id === youtubeId;
console.log("youtubeId");
console.log(youtubeId);
console.log("exists");
console.log(exists);
callback (exists);
});
};
var notExistentYoutubeId = "y0srjasdkfjcKC4eY"
existsFunc (notExistentYoutubeId, console.log)
var existentYoutubeId = "y0srjcKC4eY"
existsFunc (existentYoutubeId, console.log)
output:
❯ node /pathToFileWithCodeAbove/FileWithCodeAbove.js
youtubeId
y0srjcKC4eY
exists
true
true
youtubeId
y0srjasdkfjcKC4eY
exists
false
false
All you need is to look for the thumbnail image. In NodeJS it would be something like
var http = require('http');
function isValidYoutubeID(youtubeID) {
var options = {
method: 'HEAD',
host: 'img.youtube.com',
path: '/vi/' + youtubeID + '/0.jpg'
};
var req = http.request(options, function(res) {
if (res.statusCode == 200){
console.log("Valid Youtube ID");
} else {
console.log("Invalid Youtube ID");
}
});
req.end();
}
API_KEY is not needed. It is quite fast because there is only header check for statusCode 200/404 and image is not loaded.
I am trying to get all of the links in a subreddit using the API, but it is only returning one url. Here is the code I have:
var request = require('request');
webpage = 'http://www.reddit.com/r/AmazonUnder5/top.json?limit=100';
//login
request.post('http://www.reddit.com/api/login',{form:{api_type:'json', passwd:'password', rem:true, user:'username'}});
//get urls
request({uri : webpage, json:true, headers:{useragent: 'mybot v. 0.0.1'}}, function(error, response, body) {
if(!error && response.statusCode == 200) {
for(var key in body.data.children) {
var url = body.data.children[key].data.url;
console.log(url);
}
}
});
When I visit the json link in my browser, it returns all 100 posts.
Thats because only 1 exists in the top
http://www.reddit.com/r/AmazonUnder5/top
You could use hot instead
http://www.reddit.com/r/AmazonUnder5/hot.json
Also, you don't need to log in to do public get requests
Edit: You are getting so few results because you are not logged in properly
When logging in, use the
"op" => "login"
Parameter and test what cookies and data is returned.
I also recommend using the ssl login url since that works for me
https://ssl.reddit.com/api/login/
