I have problem getting statistics information from youtube data api. I make a request to http://gdata.youtube.com/feeds/api/videos?q=video_id&alt=json, it works for some, but for some video id, the response does not contain 'entry', 'yt$statistics', 'gd$rating' for example:
zLcbznigfs missing 'entry', aVfN6XjACDY missing 'yt$statistics', fjhQ9Kf4iHk missing 'gd$rating'
After moving around, i found out the solution for this: use &alt=atom instead of using &alt=json, which means that we better read from Atom feed than JSON (and feedparser is an excellent module for doing this). I have checked this with several video id, it works fine.
Hope that help. Thanks.

First you must know I'm a total beginner, I'm trying to learn so I almost don't know anything.
On the basic page of the API, there is a curl command used as an example to show us how to make requests.
I'm using Ruby on Rails so I used "curl-to-ruby" website to translate it, but it did not work as expected.
I wanted it to show me this :
uri = URI.parse("REQUEST_URL")
response = JSON.parse(Net::HTTP.get(uri))
Instead I got this :
uri = URI.parse("REQUEST_URL")
response = Net:HTTP.get_response(uri)
I don't understand any of this, I thought I wouldn't need to and just use "curl-to-ruby", but apparently I really need to get this.
Would you please try to explain me ?
Or give me links ?
Or matters to read (curl, API, http) ?
Thank you very much, have a nice day.
It's because that command doesn't return just the content, it returns the whole HTTP response object including headers and body. You need to extract the response body and parse that using JSON.parse(), e.g.
JSON.parse(response.body)
See documentation here: https://docs.ruby-lang.org/en/2.0.0/Net/HTTP.html#method-c-get_response
(Also, there is nothing in the cURL command which would hint to the converter that the content-type of the response was expected to be JSON (e.g. perhaps an "accepts" header or something), so even if it were able to produce extra code adding the JSON.parse part, it has no way of knowing that it would be appropriate to do so in this case.)
I'm starting to use Insight API for Twitter from IBM Bluemix.
It's hard to find supporting resource for using this. So far I am using CURL and specifically formed URL to query the API service, and the service returns results in JSON format.
Here's an example of the URL I used with CURL to search for some tweets with the API:
https://(my seucrity key)#cdeservice.mybluemix.net:443/api/v1/messages/search?q=$MSFT%28posted:2016-01-01T00:00:00Z,2016-09-01T00:00:00Z%29&size=20
This URL returns a JSON object with tweets with keyword #MSFT, and between the time frame of 2016-1-1 to 2016-9-1, only return 20 tweets.
I would like to add to that link by specifying a language for the tweet to search for, so far I come up empty. Can you please help me ?
I have tried adding the following to the URL and did not do anything:
lang=EN, lang="en"
lang:en, lang:EN
Thanks.
The syntax is lang:en and you need to make sure to include it as part of your query.
I created the following query based on the one you provided in your question:
https://username:password#cdeservice.mybluemix.net:443/api/v1/messages/search?q=(%24MSFT%20AND%20posted%3A2016-01-01T00%3A00%3A00Z%2C2016-09-01T00%3A00%3A00Z%20AND%20lang%3Aen)&size=20
The unencoded query is
($MSFT AND posted:2016-01-01T00:00:00Z,2016-09-01T00:00:00Z AND lang:en)
You can find documentation here.
But in this link you can find more details on the syntax, which is:
/api/v1/messages/search?q=QUERY&size=NUMBER&from=NUMBER
I need to create upload of images to my webserver in my Angular 2 app. Can anybody provide me some guidance how to achive this?
These are the prerequisities:
ASMX web service communicating in JSON.
post method used for communication.
JPEG / PNG up to 1MB of size.
Concept I wanted to follow (but failed)
Load the content of JPEG to variable, encode it using the Base64 coding and post it to ASMX service that will accept two parameters (token for authentication and encoded data.
What exactly is my problem
Web service was the easy part, it is done and working, but I can't manage to get the file content for enconding. I used this:
component.html
...
<input type="file" (change)="fileChangeEvent($event)" />
...
component.ts
private fileChangeEvent(fileInput: any) {
let image = fileInput.target.files[0] as File;
...
}
As you have probably guessed, the problem is in the File class, because it provides me only basic info about the file (name, size, last modif, ...) but I can't get the content of the file. Or at least I don't know how to get it. I also checked other questions here on SO, but all of the answers had something special that did not met my requirements. And maybe I'm just blind, but I can't see where the content is get.
So, is there anybody, who is able to provide me some guidelines to follow?
Thank you very much in advance.
I have left this question open for experienced guys, who could be able to answer it. There is no answer though and I found out the answer yesterday. So, after some research and modification of search phrase, I found out the answer. There is a FileReader type which can be used for reading the content of the file. Here is the source of the answer:
Getting byte array through input type = file
Thanks to original answer now I know how to do it.
Im using url_encoded_fmt_stream_map to get a List of Youtube VideoStream "urls".
I want to use these urls to show Youtube videos in my VideoView.
My method pretty much returns a String Array containing Strings like this:

If you have a close look at it, you can see that this String actually contains valid information. Unfortunately I have no idea how to extract a valid url out of this.
How would I do that?
If I create an URI with the String above and add it to my VideoView, a message "Can't play this video." pops up.
As you probably know, youtube link looks like that:
http://r6---sn-nhpax-ua8l.c.youtube.com/videoplayback?algorithm=throttle-factor&burst=40&cp=U0hVTFlTUV9HUUNONV9RTVVCOkk4ams1XzRlZUpq&cpn=qAthIxAZB16Q6_qB&expire=1367983127&factor=1.25&fexp=927900%2C919357%2C921716%2C916623%2C922911%2C931009%2C932000%2C932004%2C906383%2C904479%2C901208%2C925714%2C929119%2C931202%2C900821%2C900823%2C912518%2C911416%2C930807%2C919373%2C906836%2C926403%2C900824%2C912711%2C929606%2C910075&id=932a6c200e40b791&ip=84.228.249.95&ipbits=8&itag=34&key=yt1&ms=au&mt=1367957244&mv=m&newshard=yes&ratebypass=yes&signature=7E86D1813AE13CEB544CFF3749FBD042FF50EE91.AF7D6D9DCF286D291825630E733B3407683C46C9&source=youtube&sparams=algorithm%2Cburst%2Ccp%2Cfactor%2Cid%2Cip%2Cipbits%2Citag%2Csource%2Cupn%2Cexpire&sver=3&upn=t0jDC5Yk7Go
And as you said, all the parameters we need are shown in your string.
There are 2 important parameters we need to extract from your string: url and signature.
The Link eventually should look like this: url + "&signature=" + sig.
You can take a look at my code, where I extract all the available links out of youtube link. It's wriitten in java for an android app: link
Thank you for your effort.
I solved this problem by sticking to the official YouTube API. Also see this question:

Hoping that someone has some info on how to parse a xfa file. I can parse csv or xml files just fine, but an xfa one has come along and I'm not familar with the format. Looks like tab delimited body with column metadata at the top.
Anyone dealt with these before or can give me a steer on how to parse them?
I use vb.net but the language of any solution isn't too relevant.
Much appreciated.
Mmm, looks like nobody has a clue. The problem is that .xfa doesn't look like a "standard" extension: after all, anybody can create its own extension names, from .xyz to .something...
I looked around a bit, found, unsurprisingly (the 'x') an XML format with this extension, not much more.
Indicating where this kind of file come from, what kind of data it holds, might help. Or not.
You describe the file as being a simple TSV (tab separated values) with a header. It is quite trivial to parse, with a tokenizer or some regex, so I am not sure where you are stuck.
I think you might be talking about this: http://en.wikipedia.org/wiki/XFA_forms
This seemed to be a page that was designed to deal with that template: http://www.w3.org/1999/05/XFA/xfa-template-19990614
That information should be enough to get the ball rolling. If that fails then you can always analyse the file itself for patterns and go from there. I don't see it being too tricky.
Anyway, I hope that helps.
P.S. If you could provide a link to that .xfa we could probably give you more help.
The original post says the content looks like "tab delimited body with column metadata at the top". An XFA form doesn't look anything like that - XFA forms typically use a *.xdp extension and are XML.
