Extracto de resultados de JSONP en PHP

Question

Me gustaría poder acceder a los datos devueltos de esta url. ¿Puedo hacer esto en PHP?

<?php 
    $yahooSS = "http://d.yimg.com/autoc.finance.yahoo.com/autoc?query=yahoo&callback=YAHOO.Finance.SymbolSuggest.ssCallback"; 

    $yss = fopen($yahooSS,"r"); 
    .... 

creo que esto devuelve una función de devolución de llamada de Javascript, pero no tengo ni idea de por dónde empezar.

A continuación se muestra un ejemplo del conjunto de resultados devueltos.

YAHOO.Finance.SymbolSuggest.ssCallback({"ResultSet":{"Query":"yahoo","Result":[{"symbol":"YHOO","name": "Yahoo! Inc.","exch": "NMS","type": "S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"YAHOY.PK","name": "YAHOO JAPAN CORP","exch": "PNK","type": "S","exchDisp":"Pink Sheets","typeDisp":"Equity"},{"symbol":"ETD","name": "Citigroup Inc. ELKS On Yahoo","exch": "PCX","type": "S","typeDisp":"Equity"},{"symbol":"YOJ.BE","name": "YAHOO JAPAN","exch": "BER","type": "S","exchDisp":"Berlin","typeDisp":"Equity"},{"symbol":"YHO.SG","name": "YAHOO","exch": "STU","type": "S","exchDisp":"Stuttgart","typeDisp":"Equity"},{"symbol":"YAHOF.PK","name": "YAHOO JAPAN CORP","exch": "PNK","type": "S","exchDisp":"Pink Sheets","typeDisp":"Equity"},{"symbol":"YHO.HM","name": "YAHOO","exch": "HAM","type": "S","exchDisp":"Hamburg","typeDisp":"Equity"},{"symbol":"YOJ.DE","name": "YAHOO JAPAN","exch": "GER","type": "S","exchDisp":"XETRA","typeDisp":"Equity"},{"symbol":"YHO.DU","name": "YAHOO","exch": "DUS","type": "S","exchDisp":"Dusseldorf Stock Exchange","typeDisp":"Equity"},{"symbol":"YHOO.BA","name": "YAHOO INC.","exch": "BUE","type": "S","exchDisp":"Buenos Aires","typeDisp":"Equity"}]}}) 

Cualquier ayuda es muy apreciada.

Answer 1

Derecho, es JSON with padding. Tiene que eliminar el nombre de la función (y paréntesis) y luego puede analizar el JSON con json_decode.

una vez me escribió una función para la que:

function jsonp_decode($jsonp, $assoc = false) { // PHP 5.3 adds depth as third parameter to json_decode 
    if($jsonp[0] !== '[' && $jsonp[0] !== '{') { // we have JSONP 
     $jsonp = substr($jsonp, strpos($jsonp, '(')); 
    } 
    return json_decode(trim($jsonp,'();'), $assoc); 
} 

Uso:

$data = jsonp_decode($response);

Answer 2

puede utilizar json_decode en php con el fin de transformar el resultado en una matriz (justo quitar la llamada de función y la paranthesis)

Answer 3

Pruebe esto primero, podría ahorrarle problemas: simplemente omita el parámetro callback de la URL.

Este webservice tiene el comportamiento bastante estándar de producir JSONP si se define callback; JSON simple de lo contrario. Inténtelo:

http://d.yimg.com/autoc.finance.yahoo.com/autoc?query=yahoo&region=us&lang=eng

vuelve JSON sencillo:

{"ResultSet":{"Query":"yahoo","Result":[{"symbol":"YHO.HM","name":"YAHOO","exch":"HAM","type":"S","exchDisp":"Hamburg","typeDisp":"Equity"},{"symbol":"YHOO","name":"Yahoo! Inc.","exch":"NAS","type":"S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"YAHOY","name":"Yahoo Japan Corporation","exch":"PNK","type":"S","exchDisp":"OTC Markets","typeDisp":"Equity"},{"symbol":"YHOO.MX","name":"Yahoo! Inc.","exch":"MEX","type":"S","exchDisp":"Mexico","typeDisp":"Equity"},{"symbol":"YAHOF","name":"Yahoo Japan Corporation","exch":"PNK","type":"S","exchDisp":"OTC Markets","typeDisp":"Equity"},{"symbol":"YHOO.BA","name":"Yahoo! Inc.","exch":"BUE","type":"S","exchDisp":"Buenos Aires","typeDisp":"Equity"},{"symbol":"YHO.F","name":"YAHOO","exch":"FRA","type":"S","exchDisp":"Frankfurt","typeDisp":"Equity"},{"symbol":"YHO.MU","name":"YAHOO","exch":"MUN","type":"S","exchDisp":"Munich","typeDisp":"Equity"},{"symbol":"YHO.DE","name":"Yahoo! Inc.","exch":"GER","type":"S","exchDisp":"XETRA","typeDisp":"Equity"},{"symbol":"YHOO.F","name":"YAHOO","exch":"FRA","type":"S","exchDisp":"Frankfurt","typeDisp":"Equity"}]}} 

http://d.yimg.com/autoc.finance.yahoo.com/autoc?query=yahoo&region=us&lang=eng&callback=YAHOO.Finance.SymbolSuggest.ssCallback

vuelve JSONP (JSON envueltos en una llamada de función):

YAHOO.Finance.SymbolSuggest.ssCallback({"ResultSet":{"Query":"yahoo","Result":[{"symbol":"YHO.HM","name":"YAHOO","exch":"HAM","type":"S","exchDisp":"Hamburg","typeDisp":"Equity"},{"symbol":"YHOO","name":"Yahoo! Inc.","exch":"NAS","type":"S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"YAHOY","name":"Yahoo Japan Corporation","exch":"PNK","type":"S","exchDisp":"OTC Markets","typeDisp":"Equity"},{"symbol":"YHOO.MX","name":"Yahoo! Inc.","exch":"MEX","type":"S","exchDisp":"Mexico","typeDisp":"Equity"},{"symbol":"YAHOF","name":"Yahoo Japan Corporation","exch":"PNK","type":"S","exchDisp":"OTC Markets","typeDisp":"Equity"},{"symbol":"YHOO.BA","name":"Yahoo! Inc.","exch":"BUE","type":"S","exchDisp":"Buenos Aires","typeDisp":"Equity"},{"symbol":"YHO.F","name":"YAHOO","exch":"FRA","type":"S","exchDisp":"Frankfurt","typeDisp":"Equity"},{"symbol":"YHO.MU","name":"YAHOO","exch":"MUN","type":"S","exchDisp":"Munich","typeDisp":"Equity"},{"symbol":"YHO.DE","name":"Yahoo! Inc.","exch":"GER","type":"S","exchDisp":"XETRA","typeDisp":"Equity"},{"symbol":"YHOO.F","name":"YAHOO","exch":"FRA","type":"S","exchDisp":"Frankfurt","typeDisp":"Equity"}]}});
