在PHP中提取JSONP结果集

我希望能够得到这个url的返回数据。 我甚至可以在PHP中做到这一点？

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

我相信这将返回一个Javascriptcallback函数，但我不知道从哪里开始。

以下是返回的结果集示例。

 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"}]}}) 

任何帮助是极大的赞赏。

对，这是填充JSON。 你必须删除函数名（和括号），然后你可以用json_decodeparsingJSON。

我曾经为此写过一个函数：

 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); } 

用法：

 $data = jsonp_decode($response);

先试试这个，它可以为您节省麻烦： 只需从URL中省略callback参数即可 。

如果callback被定义的话，这个webservice具有产生JSONP的相当标准的行为; 纯JSON否则。 尝试一下：

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

返回纯JSON：

 {"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®ion=us&lang=eng&callback=YAHOO.Finance.SymbolSuggest.ssCallback

返回JSONP（包装在函数调用中的JSON）：

 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"}]}});

你可以在php中使用json_decode来将结果转换为一个数组（只是删除函数调用和paranthesis）
