透過JS跨網域存取XML檔
為了一些安全性的因素,通常伺服器會阻擋跨網域的XML存取,當然如果你是該網站開發者,所開發的頁面應該將會被放在被認可的網域中,不會碰到這個問題,但我們在開發前期有可能會不在所屬的網域,這樣就會造成開發上的困難,不過我們可以透過Yahoo所提供的YQL查詢語法來解決這個問題,以下就是相關的說明:
若我們在自己的電腦用以下的語法去存取一個網路上的XML
<script> $(function () { var xmlSource = "http://stanley.cloudlab.tw/crossDomainXML/testXML.xml"; $.ajax({ url: xmlSource, success: function (data) { console.log(data); } }) }) </script>
很可能會出現「No Access Control Allow Origin」的訊息:
但如果套用上YQL之後
<script> $(function(){ var xmlSource = "http://stanley.cloudlab.tw/crossDomainXML/testXML.xml"; var yqlURL = [ "http://query.yahooapis.com/v1/public/yql", "?q=" + encodeURIComponent("select * from xml where url='" + xmlSource + "'"), "&format=xml&callback=?" ].join(""); $.getJSON(yqlURL, function(data){ console.log(data) }); }) </script>
可以看到已經可以抓到XML內容,這樣可以讓我們較為方便的去開發,其他詳細的使用說明可以參考Yahoo YQL Guide。
