I would like to know how I can filter to detect numbers (integers) only? e.g 1,2,....,10. Currently the api detects all formats of "text".
You should do that processing on your side. Use Regex to filter out numbers from string received from Vision API:
str="Text received 123,0";
number = str.replace(/\D/g,'');
result: 123
Google vision API will detect all character, google vision does not
have separate API(which can detect only number at the point of
scanning) for only numbers till now, But after scanning the image
using google vision api we will get the text in response example
"23XA3783", so now we can replace the character we don't want.
Store the google api response in temp variable
source_str = "23XA3783"
In my case I get the required string from google api response using
js
source_str= temp["responses"][0].textAnnotations[0].description
final_output = source_str.replace(/\D/g,'');

Using Google Sheets, I am trying to retrieve text passages from the Perseus Scaife Library, which has a working API.
When I query for the document node (=importxml("https://scaife-cts.perseus.org/api/cts?request=GetPassage&urn=urn:cts:greekLit:tlg0527.tlg001.opp-grc2:1.1","/")) I get all the data, including the URNs etc. However, any other xpath_query gives an error.
I know that Google Sheets can access the data, but I would like to be able to select only one node (//p).
You want to retrieve the text in passage. If my understanding is correct, how about this answer?
=importxml(A1, "//*[local-name()='passage']")
Result :
Note :
https://scaife-cts.perseus.org/api/cts?request=GetPassage&urn=urn:cts:greekLit:tlg0527.tlg001.opp-grc2:1.1 is converted by URL encode and put to "A1".
Converted URL is https://scaife-cts.perseus.org/api/cts?request=GetPassage&urn=urn%3acts%3agreekLit%3atlg0527%2etlg001%2eopp%2dgrc2%3a1%2e1.

I am developing an iOS Application for scanning QR Codes. I am successfully able to scan and get code from QR code.
Question:
My question is what are possible data types and format I can expect from QR Codes?
During my search on google I found QR Code can be used for
Contact data
Calendar data
URL
Email address
Phone number
SMS
Plain text
Geo location
Is this the complete list and is there same standard to represent above data in QR Codes? Means same way of generating QR Code for above QR types.
Is there any standard way of generating and representing data in QR Code?
Basically your text information has to be identifiable for what it is:
There is a very good summary here.
Contact data - use MeCard, or vCard (much more verbose), e.g.: MECARD:Surname, First;ADR:123 Some St., Town, Zip Code, Country;EMAIL:some_name#some_ip.com;TEL:+11800123123;BDAY:19550231;;
Gives:
Calendar data - There are two formats about iCalendar (.ics) & vCalendar (.vcs). These formats can also include location, alarm, to-do items, etc. Note that these are both verbose formats and you may be better off using a short URL to an online file in the file format but the person scanning needs to have internet connectivity and be willing to trust the QR code not to be doing anything bad.
URL: Start your url with the standard format specifier such as http://, e.g.: http://stackoverflow.com/questions/19900835/qr-code-possible-data-types-or-standards
Gives:
Email address - Start with mailto:SomeOne#SomeWhere.org gives:
Phone number - Start with tel: e.g. tel:+1-212-555-1212 gives:
SMS - See the RFC 5724.
Plain text - Just include the text.
Geo location - Use the geo:lat,long,alt format URI: geo:40.71872,-73.98905,100 (100 feet above Googles offices) gives:
WIFI - (ssid is 'abc' and password is '1234'). For WEP encryption: WIFI:S:abc;T:WEP;P:1234;;. For WPA/WPA2: WIFI:S:abc;T:WPA;P:1234;;. Without encryption: WIFI:S:abc;T:nopass;P:1234;;.
All the above example were generated with the Python qrcode package from the command line.
Basically, QR Code returns text data that can be of any type. You can put any type of data in any string format in QR Code. It totally depends on you.
You can consider it as
[NSString stringWithFormat].
Github - Zxing (Barcode Contents) has a summary.
There may or may not be a standard.
If you are looking for non-standard formats,
please update your documentation and contribute to open source.
I am using YouTube API 3 to fetch video results for which I have to make two http requests which are sequential not parallel.
1- First API call is to get youtube video ids for a search term.
https://www.googleapis.com/youtube/v3/search?part=snippet&type=video&q=QUERY_TERM&key={API KEY}
2- From first I am preparing a list of comma separated video IDs (ALL_VIDEO_IDS) and fetching individual video details like duration, viewcount etc.
https://www.googleapis.com/youtube/v3/videos?id=ALL_VIDEO_IDS&part=contentDetails,statistics&key={API KEY}
Actually I want a way so that I can get all these details in one call rather than two. How to achieve this?
Is there a way to achieve it which I don't know or I am missing something?
Here it is, with example of getting video duration,
but do not forget to create your API key at https://console.developers.google.com/project
$vidkey = "cHPMH2sa2Q" ; video key for example
$apikey = "xxxxxxxxxxxxxxxxxxxxx" ;
$dur = file_get_contents("https://www.googleapis.com/youtube/v3/videos?part=contentDetails&id=$vidkey&key=$apikey");
$VidDuration =json_decode($dur, true);
foreach ($VidDuration['items'] as $vidTime)
{
$VidDuration= $vidTime['contentDetails']['duration'];
}
I'm using the Directions API for this. The API states the parameter waypoints should be used to pass locations or addresses through which needs to be navigated. When passing one waypoint, it works perfectly:
https://maps.googleapis.com/maps/api/directions/json?origin=38.04042392261285,-95.95928934382054&destination=38.02603529451354,-95.95908408863205&mode=walking&units=metric&sensor=true&waypoints=38.03945399159401,-95.94861607401845
When passing more than one waypoint, it stops working. I don't get ANY response back from the request. Note that I separated the locations with the pipe symbol (|) as stated in the API:
https://maps.googleapis.com/maps/api/directions/json?origin=38.04042392261285,-95.95928934382054&destination=38.02603529451354,-95.95908408863205&mode=walking&units=metric&sensor=true&waypoints=38.03945399159401,-95.94861607401845|38.02603529451354,-95.94943709477245
Seems the pipe character is not being escaped, I was using this:
waypointsURL = [waypointsURL stringByAppendingString:#"|"];
Instead, use this:
waypointsURL = [waypointsURL stringByAppendingString:#"%7C"];
How can I use Twitter Search API (or other) to get a list of tweets which have the "geo" param?
--EDIT--
By example: I wont get list of geotagged tweets, by #apple tag. Without location filter, worldwide.
Looks like the latest API supports that; simply use a large enough geo region for your query:
-180,-90,180,90
See more from the API link for filter and location
The streaming API allowed you to filter by a location and the search API allows you to search by geocode. You can find more information on these services on our developer resources site.
Streaming API: http://dev.twitter.com/pages/streaming_api
Example: Create a file called ‘locations’ that
contains, excluding the quotation
marks, the phrase:
“locations=-122.75,36.8,-121.75,37.8,-74,40,-73,41” then execute:
curl -d #locations
http://stream.twitter.com/1/statuses/filter.json
-uAnyTwitterUser:Password.
You will receive all geo tagged tweets
from the San Francisco and New York
City area.
Search API: http://dev.twitter.com/doc/get/search
Example: http://search.twitter.com/search.json?geocode=37.781157,-122.398720,1mi
From the Twitter API Documentation, this should be the format of your search query:
http://search.twitter.com/search.json?geocode=37.781157,-122.398720,1mi
Where 37.781157 is the latitude, -122.398720 is the longitude and 1mi is the radius to search within.
You can look for every tweet but save only the geotaged ones.
I know it dont make a lot of sense, but works quite well.
if you call you search results, you can state
for result in results:
if result.geo != None:
print result.text.encode('utf-8', errors='ignore') # or do anything you want with the tweets
Use -180,-90,180,90 to get any geotagged tweet.
