问题
I'm using $resource to get data from my RESTful service and I need to read response headers to get 'X-Page' and 'X-Total-Pages' value for pagination.
Example:
Access-Control-Max-Age:1728000
Cache-Control:max-age=0, private, must-revalidate
Connection:Keep-Alive
Content-Length:2637
Content-Type:application/json
Date:Thu, 10 Apr 2014 16:53:01 GMT
Server:WEBrick/1.3.1 (Ruby/2.1.1/2014-02-24)
Vary:Origin
X-Page:1
X-Per-Page:10
X-Total:17
X-Total-Pages:2
But I couldn't get full headers from server.
This is returned headers:
This is the headers from server:
This is my code:
.factory('TestAPI', ['$resource',
function ($resource) {
return $resource("http://ip.jsontest.com/?callback=showIP", {}, {
query: {
method: 'GET'
}
});
}])
TestAPI.query({}, function (value, responseHeaders) {
console.log(responseHeaders());
}, function (response) {
console.log(response);
});
回答1:
In your response headers you have to add the following header:
Access-Control-Expose-Headers: X-Total-Pages, X-Page
With this, the browser is capable to expose your customs headers an read it angular.
回答2:
After doing what @nancoder said
You could read the header by adding an interceptor to your $resource.
It would looks like this
.factory('TestAPI', ['$resource',
function ($resource) {
return $resource("http://ip.jsontest.com/?callback=showIP", {}, {
query: {
method: 'GET',
interceptor: {
response: function (resp) {
console.log(resp.headers("X-Total-Pages"));
console.log(resp.headers("X-Page"));
return resp.resource;
}
}
}
});
}])
