Using YouTube API on HTML page with Javascript - javascript

I am new to web development and am trying to make a very simple search page that displays YouTube videos using the YouTube API. I've been following the examples from here: https://developers.google.com/youtube/v3/code_samples/javascript?hl=fr#search_by_keyword
but I'm not having a lot of luck. I have no errors but no search results either.
My current code is here: http://amalthea5.github.io/thinkful-tube/

There seems to be several problems.
You need to use
<script src="https://apis.google.com/js/client.js?onload=googleApiClientReady"></script>
instead of
<script src="https://apis.google.com/js/client.js?onload=onClientLoad" type="text/javascript"></script>
because you need to make sure the initialization function googleApiClientReady() in auth.js is called.
However, the Google API also reports that there exists no OAuth client with the ID trusty-sentinel-92304.
Edit:
If don't have an OAuth client ID, but rather an API key, you shouldn't use the auth API at all. Instead, you need to add the API key as parameter to each API call (as described here: https://developers.google.com/youtube/v3/docs/standard_parameters).
Try this as a start:
gapi.client.load('youtube', 'v3', function() {
var request = gapi.client.youtube.search.list({
key: "YOUR_API_KEY",
q: "cats",
part: 'snippet'
});
request.execute(function(response) {
var str = JSON.stringify(response.result);
console.log(str);
});
});

To begin with if you read the very tutorial you are following again, it says that:
Again, you need to update the client ID in the auth.js file to run this code.
Which looks like you didnt,
also by running a search query from the console I get the following error:
TypeError: gapi.client.youtube is undefined
Meaning the api is not initiated, You should double check the way you embed the google javascript file and the priority of doing so (the order of them)

How to make a live post request first promoter affiliate using js

Hello I am working on a project that requires me to track pages using first promoter.
see below api documentation
https://docs.firstpromoter.com/#api-reference
what i need to do is get the present cookie of the website and pass the "vistior tracking id" as below using the link and js.
https://######.com?fpr=testvstihyao&test_mode=1`
<script>(function(w){w.fpr=w.fpr||function(){w.fpr.q = w.fpr.q||[];w.fpr.q[arguments[0]=='set'?'unshift':'push'](arguments);};})(window);
fpr("init", {cid:"######"});
fpr("click");
</script>
<script src="https://cdn.firstpromoter.com/fpr.js" async></script>
<script>
var x = document.cookie;
window.alert(x);
</script>
also see screenshots of request made
enter image description here
and then I make a request to using first promoters documentation as below
enter image description here
so everything works while testing.
But when i try to track my page like this https://######.com?fpr=dee. (without the test mode i am unable to get a tid which I am supposed to use to make an api request.
I was expecting to get the tid when i tried to access the cookie with the tesmode parameter
I must be missing something, please help

connecting javascript to a Web API

I am new to the web development world and I would like to be able to connect an HTML page to a web api through . and I was really not successful in this.
I followed this tutorial to be able to make this connection : http://www.asp.net/web-api/overview/getting-started-with-aspnet-web-api/tutorial-your-first-web-api
All I need is to send some inputs from an HTML page to a web api that takes these parameters and returns an object
I am using this code
$.getJSON("api/GeneratorController/setparameters/"+firstparameter+"/"+secondparameter+"/"+thirdparameter+"/"+fourthparameter+"/"+fifthparameter+"/"+sixthparameter,
function (data) {
alert(data); //never comes here
}).fail(function (jqXHR, textStatus, err) {
alert("All checks are correct, image was not generated. jqXHR = " + jqXHR.valueOf() + " textStatus=" + textStatus + " Error" + err);
});
it always goes into the fail portion , I attached the alert message that comes out of it
Any Reason why it is doing this ?
#smartmeta (I changed the typo , thanks) I followed your advice and here is the output of the alert (as expected , values that I have inserted are displayed):
Your url needs to start with your domain, not 'api/generatorcontroller/...'. If you are developing locally, something like http://localhost:[port]/api/generatorController/....
Also, webApi maps to url verbs, (get, post, put, delete..), not functions like setparameters, unless you have a [name=setparameters] above your get() function.
Also, I am pretty sure you don't have a route setup to handle the url with all those parameters. What you want to look at, as it seems your using jQuery, is jQuery.get documentation. The second example near the bottom shows where to place parameters. WebAPI will check for them in the body if they are not in the query string. so it would end up looking like:
$.getJSON("http://"+window.location.host+"/api/GeneratorController/setparameters", {parameter1: parameter1, parameter2:parameter2 ...});
Well, the first thing to check is to make sure that your server-side function is returning the values you expect. You can do this with Chrome's developer tools or with the Firebug Firefox extension, and I think IE10 has something equivalent, too. Go to the "net" tab, find the request corresponding to your API call, and take a look at what the server responded with.
Please add the line
alert("api/GeneratorController/setparameters/"+firstparemeter+"/"+secondparameter+"/"+thirdparameter+"/"+fourthparameter+"/"+fifthparameter+"/"+sixthparameter)
Then call your script and take the output of the alert into a browser. Then check if your application Handels that route.
By the way I think you have a typo. I guess it should be firstparameter.
I assume you would like to do
"api/GeneratorController?foo=Bar
But when you are new to this, I would suggest that you first try the example like it is. And After that you can start changing setails.
So I found what was the problem with my code
Two things :
1- I shouldn't use the word "Controller" when I call my API ,it should be api/Generator/...
2- the function name needs to start with "get" and not "set" since it "gets" the return value from the api
Thanks everyone!

Get Twitter Feed as JSON without authentication

I wrote a small JavaScript a couple of years ago that grabbed a users (mine) most recent tweet and then parsed it out for display including links, date etc.
It used this json call to retrieve the tweets and it no longer works.
http://twitter.com/statuses/user_timeline/radfan.json
It now returns the error:
{"errors":[{"message":"Sorry, that page does not exist","code":34}]}
I have looked at using the api version (code below) but this requires authentication which I would rather avoid having to do as it is just to display my latest tweet on my website which is public anyway on my profile page:
http://api.twitter.com/1/statuses/radfan.json
I haven't kept up with Twitter's API changes as I no longer really work with it, is there a way round this problem or is it no longer possible?
Previously the Search API was the only Twitter API that didn't require some form of OAuth. Now it does require auth.
Twitter's Search API is acquired from a third party acquisition - they rarely support it and are seemingly unenthused that it even exists. On top of that, there are many limitations to the payload, including but not limited to a severely reduced set of key:value pairs in the JSON or XML file you get back.
When I heard this, I was shocked. I spent a LONG time figuring out how to use the least amount of code to do a simple GET request (like displaying a timeline).
I decided to go the OAuth route to be able to ensure a relevant payload. You need a server-side language to do this. JavaScript is visible to end users, and thus it's a bad idea to include the necessary keys and secrets in a .js file.
I didn't want to use a big library so the answer for me was PHP and help from #Rivers' answer here. The answer below it by #lackovic10 describes how to include queries in your authentication.
I hope this helps others save time thinking about how to go about using Twitter's API with the new OAuth requirement.
You can access and scrape Twitter via advanced search without being logged in:
https://twitter.com/search-advanced
GET request
When performing a basic search request you get:
https://twitter.com/search?q=Babylon%205&src=typd
q (our query encoded)
src (assumed to be the source of the query, i.e. typed)
by default, Twitter returns top 25 results, but if you click on
all you can get the realtime tweets:
https://twitter.com/search?f=realtime&q=Babylon%205&src=typd
JSON contents
More Tweets are loaded on the page via AJAX:
https://twitter.com/i/search/timeline?f=realtime&q=Babylon%205&src=typd&include_available_features=1&include_entities=1&last_note_ts=85&max_position=TWEET-553069642609344512-553159310448918528-BD1UO2FFu9QAAAAAAAAETAAAAAcAAAASAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Use max_position to request the next tweets
The following json array returns all you need to scrape the contents:
https://twitter.com/i/search/timeline?f=realtime&q=Babylon%205&src=typd
has_more_items (bool)
items_html (html)
max_position (key)
refresh_cursor (key)
DOM elements
Here comes a list of DOM elements you can use to extract
The authors twitter handle
div.original-tweet[data-tweet-id]
The name of the author
div.original-tweet[data-name]
The user ID of the author
div.original-tweet[data-user-id]
Timestamp of the post
span._timestamp[data-time]
Timestamp of the post in ms
span._timestamp[data-time-ms]
Text of Tweet
p.tweet-text
Number of Retweets
span.ProfileTweet-action–retweet > span.ProfileTweet-actionCount[data-tweet-stat-count]
Number of Favo
span.ProfileTweet-action–favorite > span.ProfileTweet-actionCount[data-tweet-stat-count]

https://code.recuweb.com/2015/scraping-tweets-directly-from-twitter-without-authentication/
If you're still looking for unauthenticated tweets in JSON, this should work:
https://github.com/cosmocatalano/tweet-2-json
As you can see in the documentation, using the REST API you'll need OAuth Tokens in order to do this. Luckily, we can use the Search (which doesn't use OAuth) and use the from:[USERNAME] operator
Example:
http://search.twitter.com/search.json?q=from:marcofolio
Will give you a JSON object with tweets from that user, where
object.results[0]
will give you the last tweet.
Here is a quick hack (really a hack, should be used with caution as its not future proof) which uses http://anyorigin.com to scrape twitter site for the latest tweets.
http://codepen.io/JonOlick/pen/XJaXBd
It works by using anyorigin (you have to pay to use it) to grab the HTML. It then parses the HTML using jquery to extract out the relevant tweets.
Tweets on the mobile site use a div with the class .tweet-text, so this is pretty painless.
The relevant code looks like this:
$.getJSON('http://anyorigin.com/get?url=mobile.twitter.com/JonOlick&callback=?', function(data){
// Remap ... utf8 encoding to ascii.
var bar = data.contents;
bar = bar.replace(/…/g, '...');
var el = $( '<div></div>' );
el.html(bar);
// Change all links to point back at twitter
$('.twitter-atreply', el).each(function(i){
$(this).attr('href', "https://twitter.com" + $(this).attr('href'))
});
// For all tweets
$('.tweet-text', el).each(function(i){
// We only care about the first 4 tweets
if(i < 4) {
var foo = $(this).html();
$('#test').html($('#test').html() + "<div class=ProfileTweet><div class=ProfileTweet-contents>" + foo + "</div></div><br>");
}
});
});
You can use a Twitter API wrapper, such as TweetJS.com which offers a limited set of the Twitter API's functionality, but does not require authentication. It's called like this;
TweetJs.ListTweetsOnUserTimeline("PetrucciMusic",
function (data) {
console.log(data);
});
You can use the twitter api v1 to take the tweets without using OAuth. For example: this link turns #jack's last 100 tweets.
The timeline documentation is here.
The method "GET statuses/user_timeline" need a user Authentification like you can see on the official documentation :
You can use the search method "GET search" wich not require authentification.
You have a code for starting here : http://jsfiddle.net/73L4c/6/
function searchTwitter(query) {
$.ajax({
url: 'http://search.twitter.com/search.json?' + jQuery.param(query),
dataType: 'jsonp',
success: function(data) {
var tweets = $('#tweets');
tweets.html('');
for (res in data['results']) {
tweets.append('<div>' + data['results'][res]['from_user'] + ' wrote: <p>' + data['results'][res]['text'] + '</p></div><br />');
}
}
});
}
$(document).ready(function() {
$('#submit').click(function() {
var params = {
q: $('#query').val(),
rpp: 5
};
// alert(jQuery.param(params));
searchTwitter(params);
});
})

Facebook Search API Untrusted Connection

I am trying to search the Facebook API from my application using javascript FB.api(url, success function) and the JSON object that comes back contains the error: "Search queries are unsupported for this connection."
The url I'm using is: "https://graph.facebook.com/search?q=Bamboo&type=page&access_token=", which works when I'm testing it in browser
Why is my search unsupported???
The problem is your url. You only put your graph api command in the url parameter, thus the "https://graph.facebook.com" shouldn't be included.
For using the search call,
var urlCall = "/search?q=Bamboo&type=page&access_token=";
FB.api(urlCall, function(response) {
//you code to execute
});
and not the following
url = "https://graph.facebook.com/search?q=Bamboo&type=page&access_token="

Using last.fm API in javascript

I have very little experience with web development. I have a little experience with HTML and I am learning JavaScript right now. I created a program in Java using a a last.fm library for Java. I was able to get user information, artist information, and venue information. Now I want to try and do that in a webpage, which is where my problem occurs.
I'm using the javascript last.fm api given here http://github.com/fxb/javascript-last.fm-api
I've downloaded all the .js files and they are in the same directory as my .htm file.
This is my code so far.
<html>
<body>
<script type="text/javascript" src="lastfm.api.md5.js"></script>
<script type="text/javascript" src="lastfm.api.js"></script>
<script type="text/javascript" src="lastfm.api.cache.js"></script>
<script type="text/javascript">
var cache = new LastFMCache();
var lastfm = new LastFM({
apiKey : 'c9946d11aaaaaaaaaaaaaaaaaaaaaaaace',
apiSecret : '9dabf9aaaaaaaaaaaaaaaaxxx11ec3c7a993',
cache : cache
});
lastfm.artist.getInfo({artist: 'The xx'}, {success: function(data){
/* Use Data */
}, error: function(code, message){
/* Show error message. */
}});
</script>
</body>
</html>
I've dug around in the included .js files to try and understand what is going on. So on my initialization of lastfm, I am passing in some objects with associated values, which are then applied to lastfm. If I try and access them through document.write(lastfm.apiKey) I get an undefined value, which I don't really understand.
Also I see that I am calling getInfo and passing in 'The xx' and everything that follows. I don't understand how to use that Data that I believe is returned as a JSON response. How can I print the bio that is associated with that artist?
the code that should go where you have written /* Use Data */ will refer to items such as data.bio. Try alert(data) to see what's in there.
I would also highly recommend using a JavaScript debugging console such as FireBug in order to really see what's going on.
i just used this, and yeah. you just need to console.log(data) in the success to get info about the data that is being passed back from last fm
