JavaScript 跨域請求庫：XDomain

XDomain 是 JavaScript CORS 跨域請求的一個替代產品，無需任何服務器端的配置。只需要在同域下放置一個 proxy.html 文件即可。該庫利用 XHook 來獲取所有 XHR，可以無縫的和其他庫協同工作。

特性

• 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

瀏覽器支持情況：

示例代碼：

//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);
});
