我打了一下,與goo.gl API和Javascript:解析錯誤使用使用<a href="http://call.jsonlib.com/jsonlib-src.js" rel="nofollow">jsonlib</a>這樣jsonlib
function googl(url, cb) {
jsonlib.fetch({
url: 'https://www.googleapis.com/urlshortener/v1/url?key=<my-api-key>',
header: 'Content-Type: application/json',
data: JSON.stringify({longUrl: url})
}, function (m) {
var result = null;
try {
result = JSON.parse(m.content).id;
if (typeof result != 'string') {
result = null;
}
} catch (e) {
result = null;
}
cb(result);
});
}
但是當我嘗試運行此,我得到這個錯誤:
ReferenceError: Can't find variable: jsonlib_cb_1307278663586 - fetch:1
的fetch:1
內容:
jsonlib_cb_1307278663587({"url": "https://www.googleapis.com/urlshortener/v1/url?key=<my-api-key>", "headers": {"via": "HTTP/1.1 GWA", "x-content-type-options": "nosniff", "x-google-cache-control": "remote-fetch", "expires": "Fri, 01 Jan 1990 00:00:00 GMT", "server": "GSE", "x-xss-protection": "1; mode=block", "etag": "\"0CNIIHrQYpIA69r1Pk9QCe1kzwI/u2pHqKdqG-dNhbJgEDlvIXi9lWk\"", "pragma": "no-cache", "cache-control": "no-cache, no-store, max-age=0, must-revalidate", "date": "Sun, 05 Jun 2011 13:14:52 GMT", "x-frame-options": "SAMEORIGIN", "content-type": "application/json; charset=UTF-8"}, "original-encoding": "iso-8859-1", "content": "{\n \"kind\": \"urlshortener#url\",\n \"id\": \"http://goo.gl/45cs\",\n \"longUrl\": \"http://developer.android.com/guide/practices/ui_guidelines/icon_design.html\"\n}\n"})
我需要做什麼改正這個?
PS:我已經移除代碼我的API密鑰將其公開,在我測試的API密鑰是存在的,它是正確的,因爲我可以看到有效的JSON,如果我點擊fetch:1

響應表明您實際上正在使用[JSONP](http://en.wikipedia.org/wiki/JSONP),您不應該解析它,但讓插入的腳本調用回調函數,解析參數。這是必要的,因爲您不能跨域發佈XMLHttpRequest。 – 2011-06-05 14:57:16
