问题描述
我正在尝试使用apiary api进行测试，如下所示:
I am trying to perform test using apiary api as the following:
$scope.createAsset = function () {
$http({
method: 'POST',
url: 'http://polls.apiblueprint.org/createStory',
headers: {'Access-Control-Allow-Origin': '*'}
});
}
养蜂场:
FORMAT: 1A
HOST: http://polls.apiblueprint.org/
# BulBulTest
BulBulTest is a simple API for testing.
## Create story [/createStory]
### Create story [POST]
+ Response 200 (application/json)
{
"Status": "Story created sucessfully",
"published_at": "2015-08-05T08:40:51.620Z",
"publisher": "Johm Smith"
}
，即使设置了 allow-origin ，我仍然收到错误消息.
and I get error even after setting the allow-origin.
推荐答案
您对CORS : Access-Control-Allow-Origin 标头来自服务器，而不是客户端.服务器决定是否允许跨域调用.
You have a misunderstanding of CORS: The Access-Control-Allow-Origin header comes from the server, not the client. It's the server that decides whether to allow a cross-origin call.
在服务器不支持的跨域调用中，客户端代码中您无能为力.
There's nothing you can do in your client-side code to enable a cross-origin call if the server doesn't support it.
