除了内容类型和缓存控制之外，无法响应jquery getJson调用的标头

Question

I'm doing a getJson call with jquery like this

jQuery.getJSON("api.url.com/resource", function(result, status, hxr) {
  console.log(hxr.getAllResponseHeaders());
  console.log(hxr.getResponseHeader('link'));
});

I'm only getting for hxr.getAllResponseHeaders()

content-type: application/json; charset=utf-8
cache-control: public, max-age=60, s-maxage=60

hxr.getResponseHeader('link') is showing null,

What am I doing wrong to get the other response headers This are all the headers that I'm getting for the request

Access-Control-Allow-Origin:*
cache-control:public, max-age=60, s-maxage=60
connection:close
content-length:8426
content-type:application/json; charset=utf-8

Aditional Notes:

1. This is a cross-domain call
2. I'm using jquery 1.11.0

Answer 1

您无法在跨域调用中访问标头信息。
