I was looking to find an answer to my question, but so far I got this:
https://graph.facebook.com/the_user_id?fields=name,picture
I need to be able to display/print first,last name and picture of a set list of users for which I know their ID. What code is required to get this data and then to publish it on a php/html page? Of course, this will means that if I want to show 10 users, I will input 10 different IDs (read smtg about an array list?). Notice that I DO NOT require for this to work for the current user.
Thanks in advance for your replies.
You need to use file_get_contents ( http://uk3.php.net/file_get_contents ) or curl in php and issue a request to the url such as follows:
https://graph.facebook.com/?ids=id1,id2,id3&fields=name,picture
(replacing id1,id2 with your ids)
this will then return you a json object. You then need to decode ( http://uk3.php.net/json_decode ) and loop through this and access the information
this should get you started
// people array uses the users id as the key and the dessert as the value. The id is then used in the query to facebook to select the corresponding value from this array
$people = array("id1"=>"favourite "dessert", "id2"=>"favourite dessert", "id3"=>"apple pie");
$json = file_get_contents('https://graph.facebook.com/?ids=id1,id2,id3&fields=id,name,picture');
$json = json_decode($json);
foreach($json as $key=>$person){
echo '<p><img src="'.$person->picture.'" alt="'.$person->name.'" />';
echo $person->name.'\'s favourite dessert is '.$people[$person->id'];
echo '</p>';
}
I've batched the requests here, alternatively you could perform 10 separate queries for each user, but that would be a bit pointless and inefficient
The easiest way is with an FQL query:
SELECT first_name, last_name, pic, uid FROM user WHERE uid IN
(Known_ID_1, Known_ID_2, ... Known_ID_n)
The easiest, if you're using PHP is to install the PHP SDK, though you can also make a call directly to https://graph.facebook.com/fql?q=URL_ENCODED_QUERY

I am experimenting using elasticsearch in a dummy project in django. I am attempting to make a search page using django-elasticsearch-dsl. The user may provide a title, summary and a score to search for. The search should match all the information given by the user, but if the user does not provide any info about something, this should be skipped.
I am running the following code to search for all the values.
client = Elasticsearch()
s = Search().using(client).query("match", title=title_value)\
.query("match", summary=summary_value)\
.filter('range', score={'gt': scorefrom_value, 'lte': scoreto_value})
When I have a value for all the fields then the search works correctly, but if for example I do not provide a value for the summary_value, although I am expecting the search to continue searching for the rest of the values, the result is that it comes up with nothing as a result.
Is there some value that the fields should have by default in case the user does not provide a value? Or how should I approach this?
UPDATE 1
I tried using the following, but it returns every time no matter the input i am giving the same results.
s = Search(using=client)
if title:
s.query("match", title=title)
if summary:
s.query("match", summary=summary)
response = s.execute()
UPDATE 2
I can print using the to_dict().
if it is like the following then s is empty
s = Search(using=client)
s.query("match", title=title)
if it is like this
s = Search(using=client).query("match", title=title)
then it works properly but still if i add s.query("match", summary=summary) it does nothing.
You need to assign back into s:
if title:
s = s.query("match", title=title)
if summary:
s = s.query("match", summary=summary)
I can see in the Search example that django-elasticsearch-dsl lets you apply aggregations after a search so...
How about "staging" your search? I can think if the following:
#first, declare the Search object
s = Search(using=client, index="my-index")
#if parameter1 exists
if parameter1:
s.filter("term", field1= parameter1)
#if parameter2 exists
if parameter2:
s.query("match", field=parameter2)
Do the same for all your parameters (with the needed method for each) so only the ones that exist will appear in your query. At the end just run
response = s.execute()
and everything should work as you want :D
I would recommend you to use the Python ES Client. It lets you manage multiple things related to your cluster: set mappings, health checks, do queries, etc.
In its method .search(), the body parameter is where you send your query as you normally would run it ({"query"...}). Check the Usage example.
Now, for your particular case, you can have a template of your query stored in a variable. You first start with, let's say, an "empty query" only with filter, just like:
query = {
"query":{
"bool":{
"filter":[
]
}
}
}
From here, you now can build your query from the parameters you have.
This is:
#This would look a little messy, but it's useful ;)
#if parameter1 is not None or emtpy
#(change the if statement for your particular case)
if parameter1:
query["query"]["bool"]["filter"].append({"term": {"field1": parameter1}})
Do the same for all your parameters (for strings, use "term", for ranges use "range" as usual) and send the query in the .search()'s body parameter and it should work as you want.
Hope this is helpful! :D
I want to get details of a restaurant in Zomato. I have it's link as the input (https://www.zomato.com/mumbai/fantasy-the-cake-shop-kalyan?utm_source=api_basic_user&utm_medium=api&utm_campaign=v2.1). By browsing the documentation of Zomato APIs, I didn't found a way to get it.
I tried searching for the restaurant using search API but it returns many results.
Any help will be appreciated
It's a two-step process:
Find out restaurant's city id, in your case, Mumbai's city id through the /cities API. It's a simple query search.
Use the city id from the above API call in the /search API, like, https://developers.zomato.com/api/v2.1/search?entity_type=city&entity_id=3&q=fantasy%20the%20cake%20shop%20kalyan
This would give all the basic information about a restaurant.
View the page's source and search for window.RES_ID
I had the same issue as you described. This Zomato's API approach is at least odd. It's almost immposible to GET any information about restaurant if you don't know res_id in advance and that's not possible to parse since Zomato will deny access.
This worked for me:
Obtain user-key from Zomato API Credentials (https://developers.zomato.com/api)
Search restaurant url via API (https://developers.zomato.com/api/v2.1/search?entity_id=84&entity_type=city&q=RESTAURANT_URL&category=7%2C9). The more specific you will be, the better results you'll get (This url is specified by city to Prague (ID = 84) and categories Daily menus (ID = 7) and Lunch (ID = 9). If there is possibility do specify city, category or cuisine, it helps, but should't be necessary. Don't forget to define GET method in headers.
Loop or filter through json results and search for the wanted url. You might need to use method valueOf() to search for the same url. Be careful, you might need to add "?utm_source=api_basic_user&utm_medium=api&utm_campaign=v2.1" at the end of your wanted url so it has the same format. Check that through Zomato API Documentation page.
for (i in body.restaurants) {
var url_wanted = restaurant_url + '?utm_source=api_basic_user&utm_medium=api&utm_campaign=v2.1'
var url_in_json = body.restaurants[i].restaurant.url;
if (url_wanted.valueOf() == url_in_json.valueOf()) {
var restaurant_id = body.restaurants[i].restaurant.id;
}
console.log('Voala! We have res_id:' + restaurant_id);
}
There you have it. It could be easier though.
Hope it helps!
once you have the url of the rseraunt's page you can simply look for a javascript object attribute named "window.RES_ID" and further use it in the api call.
I have hundreds of registered users. Those are grouped in different user groups:
See screenshot below (I changed this a little bit to protect my customers site):
Registered -> Teachers
Registered -> Students
How can I show a list of 'Teachers' online?
I want to list up all those teachers in a table or list, so that other teachers see this information.
Thank you. Any information is welcome.
You can use the following for to get the usernames from a specific user group:
$teachers = JAccess::getUsersByGroup(2); //change number in the brackets
$students = JAccess::getUsersByGroup(8); //change number in the brackets
foreach($teachers as $user_id) {
$user = JFactory::getUser($user_id);
echo $user->name;
}
foreach($students as $user_id) {
$user = JFactory::getUser($user_id);
echo $user->name;
}
Change "2" and "8" to the ID's of the Teachers and Students user groups.
Hope this helps
Personally, I think the best way to do that is to create a contact category teachers and then link each teacher to a contact record.
You can make a list of users in a group (there's even a method JAccess::getUsersByGroup() but I don't think it's that useful for this purpose. http://officialjoomlabook.com/school25/staff-directory is an example of where I did what I am suggesting.
In fact, I want to get the cover photo for each user's albums.
So, first I get the albums data:
$albums = $GLOBALS["facebook"]->api("/me/albums",'GET');
Then I retrieve the cover_photo id and ask API to get details about this photo (such as the source)
foreach($albums as $album) {
$data = $GLOBALS["facebook"]->api("/". $album["cover_photo"], 'GET');
}
But this make a lot of calls to the API (one per album) and it's seems that she doesn't like.. Because my application return a timeout error.
Is there another way to do what I want?
Thanks.
You can always use the Batch API, or just use FQL. Something like the below would retrieve the src of all the album covers of the current user:
SELECT src
FROM photo
WHERE pid IN (
SELECT cover_pid
FROM album
WHERE owner = me()
)
You can try it here. Obviously you can choose any field to retrieve from the photo table.
When using Amazon's web service to get any product's information, is there a direct way to get the Average Customer Rating (1-5 stars)? Here are the parameters I'm using:
Service=AWSECommerceService
Version=2011-08-01
Operation=ItemSearch
SearchIndex=Books
Title=A Game of Thrones
ResponseGroup=Large
I would expect it to have a customer rating of 4.5 and total reviews of 2177. But instead I get the following in the response.
<CustomerReviews><IFrameURL>http://www.amazon.com/reviews/iframe?...</IFrameURL></CustomerReviews>
Is there a way to get the overall customer rating, besides for reading the <IFrameURL/> value, making another HTTP request for that page of reviews, and then screen scraping the HTML? That approach is fragile since Amazon could easily change the reviews page structure which would bust my application.
You can scrape from here. Just replace the asin with what you need.
http://www.amazon.com/gp/customer-reviews/widgets/average-customer-review/popover/ref=dpx_acr_pop_?contextId=dpx&asin=B000P0ZSHK
As far as i know, Amazon changed it's API so its not possible anymore to get the reviewrank information. If you check this Link the note sais:
As of November 8, 2010, only the iframe URL is returned in the request
content.
However, testing with the params you used to get the Iframe it seems that now even the Iframe dosn't work anymore. Thus, even in the latest API Reference in the chapter "Motivating Customers to Buy" the part "reviews" is compleatly missing.
However: Since i'm also very interested if its still possible somehow to get the reviewrank information - maybe even not using amazon API but a competitors API to get review rank informations - i'll set up a bounty if anybody can provide something helpful on that. Bounty will be set in this topic in two days.
You can grab the iframe review url and then use css to position it so only the star rating shows. It's not ideal since you're not getting raw data, but it's an easy way to add the rating to your page.
Sample of this in action - http://spamtech.co.uk/positioning-content-inside-an-iframe/
Here is a VBS script that would scrape the rating. Paste the code below to a text file, rename it to Test.vbs and double click to run on Windows.
sAsin = InputBox("What is your ASIN?", "Amazon Standard Identification Number (ASIN)", "B000P0ZSHK")
if sAsin <> "" Then
sHtml = SendData("http://www.amazon.com/gp/customer-reviews/widgets/average-customer-review/popover/ref=dpx_acr_pop_?contextId=dpx&asin=" & sAsin)
sRating = ExtractHtml(sHtml, "<span class=""a-size-base a-color-secondary"">(.*?)<\/span>")
sReviews = ExtractHtml(sHtml, "<a class=""a-size-small a-link-emphasis"".*?>.*?See all(.*?)<\/a>")
MsgBox sRating & vbCrLf & sReviews
End If
Function ExtractHtml(sHtml,sPattern)
Set oRegExp = New RegExp
oRegExp.Pattern = sPattern
oRegExp.IgnoreCase = True
Set oMatch = oRegExp.Execute(sHtml)
If oMatch.Count = 1 Then
ExtractHtml = Trim(oMatch.Item(0).SubMatches(0))
End If
End Function
Function SendData(sUrl)
Dim oHttp 'As XMLHTTP30
Set oHttp = CreateObject("Msxml2.XMLHTTP")
oHttp.open "GET", sUrl, False
oHttp.send
SendData = Replace(oHttp.responseText,vbLf,"")
End Function
Amazon has completely removed support for accessing rating/review information from their API. The docs mention a Response Element in the form of customer rating, but that doesn't work either.
Google shopping using Viewpoints for some reviews and other sources
This is not possible from PAPI. You either need to scrape it by yourself, or you can use other free/cheaper third-party alternatives for that.
We use the amazon-price API from RapidAPI for this, it supports price/rating/review count fetching for up to 1000 products in a single request.
