XDomainJavaScript 跨域请求库

XDomain 是 JavaScript CORS 跨域请求的一个替代产品，无需任何服务器端的配置。只需要在同域下放置一个 proxy.html 文件即可。该库利用 XHook 来获取所有 XHR，可以无缝的和其他库协同工作。

Features

• Simple




• Library Agnostic






• With jQuery  $.ajax (and subsequently $.get, $.post)




• With Angular $http service






• Cross domain XHR just magically works






• No need to modify the server code




• No need to use IE's silly XDomainRequest Object






• Easy XHR access to file servers:






• Amazon




• Dropbox






• Includes XHook and its features




• proxy.html files (slaves) may:






• White-list domains




• White-list paths using regular expressions (e.g. only allow API calls: /^\/api/)






• Highly performant




• Seamless integration with FormData

示例代码：

//do some vanilla XHR

var xhr = new XMLHttpRequest();

xhr.open('GET', 'http://xyz.example.com/secret/file.txt');

xhr.onreadystatechange = function(e) {

  if(xhr.readyState === 4)

    alert(xhr.responseText);

};

xhr.send();



//or if we are using jQuery...

$.get('http://xyz.example.com/secret/file.txt').done(function(data) {

  console.log("got result: ", data);

});
