Good time of day ,
I have a question about using jsoup.
Working with one web site I met problem that before gathering information from list of products at first I need to select radio buttons and send required data about two parameters of products : "type" and "categories".
This web site if so:
http://h17007.www1.hpe.com/us/en/networking/products/eos/index.aspx#.WzYf4NIzY2z
Because if not to do it search will give list which have only one product from unknown category .
This:
HP VCX V7205 Platform with DL 360 G6
I'm using such method at the begining.
Response response = Jsoup.connect("http://h17007.www1.hpe.com/us/en/networking/products/eos/index.aspx#.WzSdxdIzY2z")
.userAgent("Mozilla/5.0")
.timeout(10 * 1000)
.method(Method.POST)
.data("type","2")
.data("category","4")
.followRedirects(true)
.execute();
And then parse it.
Document document = response.parse();
But unfortunatly either I didn't understand how to send it correctly or I should choose another way of ,maybe , selecting correct list of products .As you may understand I try to choose second type and fouth category.
Could somebody advise how to do it ? Or advise example which could be useful for may case ?
Thank you for your attention
This is the document structure which in my bucket.
{
"_class": "com.link.pojo.Event",
"year": "2015",
"start": 1440115200000,
"name": "129811",
"domain": "5000$3$2015$Exhibition",
"sporttype": "Indoor",
"eventtype": "Exhibition",
"end": 1440151199000,
}
In here start mean event start date and the type is util Date. Example date format value is 2015-08-10T09:45:00.000+0000
Now I want to fetch all the documents start in current date using couchbase view. This is the way I'm trying to get it, What are the
// Create the CouchbaseClient Query object & Pass the time range to fetch events.
Query query = new Query();
// Filter on the start date and this value has to be within below given range params.
query.setIncludeDocs(true);
query.setDescending(true);
query.setInclusiveEnd(true);
query.setRange(ComplexKey.of(""), ComplexKey.of(""));
List<Event> eventList = `eventService.getEventsByCurrentDate(query);`
What are the values I should have to pass within query.setRange(); function. And what is the view I need to implement?
function (doc, meta) {
if (doc._class == "com.link.pojo.Event") {
emit(doc.start, null);
}
}
You're doing it wrong :]
A query is just a way to filter some of the results of a view. So start by defining a view - and then work out which query you need to use to get just what you need.
start by creating the view in Couchbase UI.
then look at the results of the view - again using couchbase UI. There should be a link you can click to see the results of the view in a new tab of your browser.
You can then edit the url to "query" the results of your view. add "&key=123 to get just that key. SetRange just means - "get the keys that fall in that range of numbers".
in your case, since your view emits the "start" field, your keys (or range) will have to be in the same format. So something like &key=1440115200000
I hope this helps.
I have a restful webservice using portal framework which gets hundreds of rows from database. I want to display on Dojo EnhancedGrid with pagination each time showing 10 rows using page numbers 10|20|30. I am able to do pagination with this example But my rest url is loading all the records from database which
leading to performance issues. There should be some event, every time when i click on page number, it should call rest url and get 10 records from database. how can i achieve this?
Dojo Enhanced Grid with Pagination makes a call to the backend REST service each time it is necessary (clicking the next page/last page/prev page/specific page/x results per page and so on..) it passes the Range parameter in the Header of the request indicating how many items it requests for the current query (i.e. Range items=0-9 will return the first 10 items and so on). So this is automatically done by the pagination support.
What you have to do is to read this parameter in the backend REST service and return the specified rows from the database. But be careful, the pagination expects an array of objects from the database.
#GET
#Path("getSearchResults")
#Produces(MediaType.APPLICATION_JSON)
public Response getSearchResults(#HeaderParam("Range") String range) {
// parse range String
// perform search
return Response.ok(responseList.toArray()).header("Content-Range", "items " + startItem + "-" + endItem + "/" + totalItems).build();
}
Also the response should contain the number of items returned and the total item number so that Pagination knows how many pages to display in the Grid and it also shows a total in the lower left corner of the Grid. This response is returned in the Header of the response as well in the following parameter: Content-Range items 0-9/120.
For no results use Content-Range: */0
on the Dojo side:
store=new JsonRest({ handleAs: 'json', target:
'{pathToServices}/rest/services/getSearchResults'});
grid = new EnhancedGrid({
id: "gridId",
store: new ObjectStore({ objectStore: store}),
structure: getGridStructure(),
plugins: {
pagination: {
pageSizes: ["25", "50", "100"],
description: true,
sizeSwitch: true,
pageStepper: true,
gotoButton: true,
maxPageStep: 4,
position: "bottom"},
}
});
That's all you have to do, Enhanced Grid Pagination takes care of everything else.
I've done my best to find the answer, but nothings seems to cover what I'm trying to do. I know how to get a single feed, from say a fan page like Starbucks, or Pepsi using the Graph API. What I want to do is get several, or multiple, feeds in a single request. Is this possible? I was told by another developer that it is, but haven't found anything on this subject in the FB documentation, or anywhere else online. I have like 50 feeds I want to aggregate into a single feed, and I don't want to make 50 different requests to get all that data.
Has anyone know how to do this, or know if it's even possible?
Thanks.
After ever MORE searching, apparently you can do this. You do this by using Batch Requests:
https://developers.facebook.com/docs/reference/api/batch/
Hope this will save someone time in the future :)
Looks like you can't really.
This works:
SELECT page_id
FROM page
WHERE username='facebook'
OR username='coca-cola'
{
"data": [
{
"page_id": 20531316728
},
{
"page_id": 40796308305
}
]
}
This works (~100 results):
SELECT post_id,message
FROM stream
WHERE source_id IN (
SELECT page_id
FROM page
WHERE username='facebook'
) LIMIT 100
But this doesn't really works (3 results):
SELECT post_id,message
FROM stream
WHERE source_id IN (
SELECT page_id
FROM page
WHERE username='facebook'
OR username='coca-cola'
) LIMIT 100
I need to sort on a date-field type, which name is "mod_date".
It works like this in the browser adress-bar:
http://localhost:8983/solr/select/?&q=bmw&sort=mod_date+desc
But I am using a phpSolr client which sends an URL to Solr, and the url sent is this:
fq=+category%3A%22Bilar%22+%2B+car_action%3AS%C3%A4ljes&version=1.2&wt=json&json.nl=map&q=%2A%3A%2A&start=0&rows=5&sort=mod_date+desc
// This wont work and is echoed after this in php:
$queryString = http_build_query($params, null, $this->_queryStringDelimiter);
$queryString = preg_replace('/%5B(?:[0-9]|[1-9][0-9]+)%5D=/', '=', $queryString);
This wont work, I dont know why!
Everything else works fine, all right fields are returned. But the sort doesn't work.
Any ideas?
Thanks
BTW: The field "mod_date" contains something like:
2010-03-04T19:37:22.5Z
EDIT:
First I use PHP to send this to a SolrPhpClient which is another php-file called service.php:
require_once('../SolrPhpClient/Apache/Solr/Service.php');
$solr = new Apache_Solr_Service('localhost', 8983, '/solr/');
$results = $solr->search($querystring, $p, $limit, $solr_params);
$solr_params is an array which contains the solr-parameters (q, fq, etc).
Now, in service.php:
$params['version'] = self::SOLR_VERSION;
// common parameters in this interface
$params['wt'] = self::SOLR_WRITER;
$params['json.nl'] = $this->_namedListTreatment;
$params['q'] = $query;
$params['sort'] = 'mod_date desc'; // HERE IS THE SORT I HAVE PROBLEM WITH
$params['start'] = $offset;
$params['rows'] = $limit;
$queryString = http_build_query($params, null, $this->_queryStringDelimiter);
$queryString = preg_replace('/%5B(?:[0-9]|[1-9][0-9]+)%5D=/', '=', $queryString);
if ($method == self::METHOD_GET)
{
return $this->_sendRawGet($this->_searchUrl . $this->_queryDelimiter . $queryString);
}
else if ($method == self::METHOD_POST)
{
return $this->_sendRawPost($this->_searchUrl, $queryString, FALSE, 'application/x-www-form-urlencoded');
}
The $results contain the results from Solr...
So this is the way I need to get to work (via php).
This code below (also on top of this Q) works but thats because I paste it into the adress bar manually, not via the PHPclient. But thats just for debugging, I need to get it to work via the PHPclient:
http://localhost:8983/solr/select/?&q=bmw&sort=mod_date+des // Not via phpclient, but works
UPDATE (2010-03-08):
I have tried Donovans codes (the urls) and they work fine.
Now, I have noticed that it is one of the parameters causing the 'SORT' not to work.
This parameter is the "wt" parameter. If we take the url from top of this Q, (fq=+category%3A%22Bilar%22+%2B+car_action%3AS%C3%A4ljes&version=1.2&wt=json&json.nl=map&q=%2A%3A%2A&start=0&rows=5&sort=mod_date+desc), and just simply remove the "wt" parameter, then the sort works.
BUT the results appear differently, thus making my php code not able to recognize the results I believe. Donovan would know this I think. I am guessing in order for the PHPClient to work, the results must be in a specific structure, which gets messed up as soon as I remove the wt parameter.
Donovan, help me please...
Here is some background what I use your SolrPhpClient for:
I have a classifieds website, which uses MySql. But for the searching I am using Solr to search some indexed fields. Then Solr returns an array of ID:numbers (for all matches of the search criteria). Then I use those ID:numbers to find everything in a MySql db and fetch all other information (example is not searchable information).
So simplified: Search -> Solr returns all matches in an array of ID:nrs -> Id:numbers from Solr are the same as the Id numbers in the MySql db, so I can just make a simple match agains every record with the ID matching the ID from the Solr results array.
I don't use Faceting, no boosting, no relevancy or other fancy stuff. I only sort by the latest classified put, and give the option to users to also sort on the cheapest price. Nothing more.
Then I use the "fq" parameter to do queries on different fields in Solr depending on category chosen by users (example "cars" in this case which in my language is "Bilar").
I am really stuck with this problem here...
Thanks for all help
As pointed out in the stack overflow comments, your browser query is different than your php client based query - to remove that from the equation you should test with this corrected. To get the same results as the browser based query you're php code should have looked something like this:
$solr = new Apache_Solr_Client(...);
$searchOptions = array(
'sort' => 'mod_date desc'
);
$results = $solr->search("bmw", 0, 10, $searchOptions);
Instead, I imagine it looks more like:
$searchOptions = array(
'fq' => 'category:"Bilar" + car_action:Sälje',
'sort' => 'mod_date desc'
)
$solr->search("\*:*", 0, 10, $searchOptions);
What I expect you to see is that php client results will be the same as the browser based results, and I imagine the same would happen if you did it the opposite way - take your current parameters from the php client and applied them correctly to the browser based query.
Now onto your problem, you don't see documents sorted properly.
I would try this query, which is the equivalent of the php client based code:
http://localhost:8983/solr/select/?&q=%2A%3A%2A&fq=+category%3A%22Bilar%22+%2B+car_action%3AS%C3%A4ljes&sort=mod_date+desc
versus this query, which moves the filter query into the main query:
http://localhost:8983/solr/select/?&q=+category%3A%22Bilar%22+%2B+car_action%3AS%C3%A4ljes&sort=mod_date+desc
and see if there is a difference. If there is, then it might be a bug in how results from cached filtered queries are used and sorted by solr - which wouldn't be a problem with the client, but the solr service itself.
Hope this gets you closer to an anser.
Use session's values for save sort parameters.
The quick answer in case someone is attempting to sort via solr-php-client:
$searchOptions = array('sort' => 'field_date desc');
Ditch the + sign that you would usually put on the URL. It took me a while as well to figure it out, I was encoding it and putting it all over the place...
It's possible it's related to the json.nl=map parameter. When the response is set to JSON with wt=json and json.nl=map, facets are not sorted as expected with the facet.sort or f.<field_name>.facet.sort=count|index options.
e.g. with facet.sort=count and wt=json only, I get:
"dc_coverage": [
"United States",
5,
"19th century",
1,
"20th century",
1,
"Detroit (Mich.)",
1,
"Pennsylvania",
1,
"United States--Michigan--Detroit",
1,
"United States--Washington, D.C.",
1
]
But with facet.sort=count, wt=json, and json.nl=map as an option, you can see the sorting is lost:
"dc_coverage": {
"19th century": 1,
"20th century": 1,
"Detroit (Mich.)": 1,
"Pennsylvania": 1,
"United States": 5,
"United States--Michigan--Detroit": 1,
"United States--Washington, D.C.": 1
}
There is more information here about formatting the JSON response when using json.nl=map: https://cwiki.apache.org/confluence/display/solr/Response+Writers#ResponseWriters-JSONResponseWriter
