推荐答案

最简单的方法是使用XMLHtt prequest，正是因为你会做从网页（只有一个网页是由相同来源的限制政策）。

Simplest way is to use XMLHttpRequest, exactly as you would do from a web page (only that a web page is limited by the same-origin policy).

var request = new XMLHttpRequest();
request.open("POST", "https://www.googleapis.com/urlshortener/v1/url");
request.setRequestHeader("Content-Type", "application/json");
request.overrideMimeType("text/plain");
request.onload = function()
{
    alert("Response received: " + request.responseText);
};
request.send('{"longUrl": "http://www.google.com/"}');

要序列化和解析JSON看到 https://developer.mozilla.org/En/Using_native_JSON。
