Parameters from URL query processed by E-Entity

Closed this issue 9 years ago · 4 comments

I'm playing with this piece of code in zend framework 2.

        $request = new Request();
        $request->getHeaders()->addHeaders(array(
            'Content-Type' => 'application/x-www-form-urlencoded; charset=UTF-8',
        ));
        $request->setUri("http://api-dev.freme-project.eu/current/e-entity/dbpedia-spotlight/documents");
        $request->setQuery(new Parameters([
            'informat' => 'text',
            'outformat' => 'json-ld', // will be fixed
            'language' => 'en',
            'confidence' => 0.3
        ]));
        $request->setMethod(Request::METHOD_POST);
        $request->setPost(new Parameters([
            "Welcome to Berlin"
        ]));
        $client = new Client();
        $response = $client->dispatch($request);
        $data = json_decode($response->getContent(), true);
        return $data;

And I have this back:

I'm doing something wrong?

Answer 1 · 2015-08-18T08:25:06.000Z

Hi Francisc,
The results are wrong, actually all the params are considered as content since you send the data as application/x-www-form-urlencoded.

I am not familiar with the performing HTTP requests with the Zend framework but here are some tips that might solve you problem:

set the Content-Type header to text/plain

set the parameters as part of the main URI.

$request->setUri("http://api-dev.freme-project.eu/current/e-entity/dbpedia-spotlight/documents?confidence=0.3&informat=text&outformat=json-ld");

send the actual text as body of the request - in Zend there is setContent function which can be used to set the body. See http://framework.zend.com/manual/current/en/modules/zend.http.request.html#zend-stdlib-message-methods-set-content

If you are familiar with cURL, here is one line command which do the same thing

request against DBpedia Spotlight

curl -v -X POST -d "Welcome to Berlin." "http://api-dev.freme-project.eu/current/e-entity/dbpedia-spotlight/documents?confidence=0.3&informat=text&outformat=json-ld" -H "Content-Type: text/plain"

request against FREME NER (recommended)

curl -v -X POST -d "Welcome to Berlin." "http://api-dev.freme-project.eu/current/e-entity/freme-ner/documents?informat=text&outformat=json-ld&dataset=dbpedia&language=en" -H "Content-Type: text/plain"

BTW, its not good practice to write your own parser for RDF (serialized as turtle, json-ld, rdf/xml, etc.). I recommend you use well-established RDF parsers for PHP. Here are some RDF libraries you can use in PHP:

http://wifo5-03.informatik.uni-mannheim.de/bizer/rdfapi/
http://graphite.ecs.soton.ac.uk/

Hope it helps!
