我正在尝试调用Google API,这是来自Firefox扩展程序的JSON帖子请求,例如
POST https://www.googleapis.com/urlshortener/v1/url
Content-Type: application/json
{"longUrl": "http://www.google.com/"}
如何调用此API并在Firefox扩展中处理响应?

最简单的方法是使用XMLHttpRequest,就像使用网页一样(只是网页受到同源策略的限制)。
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,请参阅https://developer.mozilla.org/En/Using_native_JSON。
