飞行前响应在角度中无效 [英] Response for preflight is invalid in angular

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.
