我正在使用goo.gl API和Javascript使用jsonlib这样做:
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);
});
}
但是当我尝试运行它时,我收到了这个错误:
ReferenceError:找不到变量:jsonlib_cb_1307278663586 - fetch:1
fetch:1
的内容:
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"})
我需要做些什么来纠正这个问题?
PS:我已从代码中删除了我的API密钥以使其公开,在我的测试中,API密钥就在那里并且它是正确的,因为如果我点击{{我可以看到有效的JSON Safari调试器上的1}}

您忘了将代理(在本例中为:jsonlib.com)应该用于POST
的方法设置为required by the goo.gl API。
查看the documentation of JSONlib,您应该在参数对象method
中提供另一个属性,例如:
jsonlib.fetch({
url: 'https://www.googleapis.com/urlshortener/v1/url',
header: 'Content-Type: application/json',
method: 'POST',
data: JSON.stringify({longUrl: url})
}, function (m) {
/* … */
});
现在m.content
包含
'{ "kind": "urlshortener#url", "id": "http://goo.gl/ysEOJ", "longUrl": "http://tobyho.com/Trampolines_in_Javascript_and_the_Quest_for_Fewer_Nested_Callbacks" }'
这是一个完全有效的JSON字符串。
