Extrahiere JSONP Resultset in PHP

Ich würde gerne zu den zurückgegebenen Daten dieser URL gelangen. Kann ich das auch in PHP machen?

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

Ich glaube, dass dies eine Javascript-Callback-function zurückgibt, aber ich habe keine Ahnung, wo ich anfangen soll.

Im Folgenden finden Sie ein Beispiel für das zurückgegebene Resultset.

 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"}]}}) 

Jede Hilfe wird sehr geschätzt.

Richtig, es ist JSON mit Padding. Sie müssen den functionsnamen (und die Klammer) entfernen und dann können Sie den JSON mit json_decode .

Ich habe mal eine function dafür geschrieben:

 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); } 

Verwendung:

 $data = jsonp_decode($response);

Versuchen Sie dies zuerst, es könnte Ihnen Ärger ersparen: einfach den callback Parameter aus der URL weglassen .

Dieser Webservice hat das Standardverhalten von JSONP, wenn callback definiert ist. ansonsten JSON. Versuch es:

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

Gibt JSON-Ebene zurück:

 {"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!

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

gibt JSONP zurück (JSON in einem functionsaufruf eingeschlossen):

 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!
