(Softlayer，Open Stack Swift)如何使用对象存储API解决跨域起源? [英] (Softlayer, Open Stack Swift) How to solve cross domain origin with object storage api?

问题描述

我使用了此文档: http://docs.openstack .org/developer/swift/cors.html#test-cors-page

使用以下代码，发送Option请求并获得200作为响应. 但是原始方法"get"不会得到响应. 并且浏览器控制台显示未找到"Access-Control-Allow-Origin" CORS标头.

Used the below code, sends Option request and get 200 as the response. But the orginal method 'get' doesn't get response. And browser console says 'Access-Control-Allow-Origin' CORS header is not found.

$.ajax({
    method: "GET",
    url : url,
    crossDomain: true,
    headers: {
        'X-Container-Meta-Access-Control-Allow-Origin' : 'http://127.0.0.1:8080',
        'X-Container-Meta-Access-Control-Max-Age' : 10,
        'X-Auth-Token' : token
    },  
    contentType : 'application/json; charset=utf-8'
});

推荐答案

如果内存用于SL对象存储，则仅支持容器上的CORS，而不支持单个对象.应该支持以下标头:

If memory serves the SL Object Storage only support CORS on containers and not individual objects. The following headers should be supported:

X容器元访问控制允许来源
允许起源发出交叉起源请求，以空格分隔.

X-Container-Meta-Access-Control-Allow-Origin
Origins to be allowed to make Cross Origin Requests, space separated.

X容器元访问控制最大年龄
Origin保留预检结果的最大年龄.

X-Container-Meta-Access-Control-Max-Age
Max age for the Origin to hold the preflight results.

X容器-元访问控制-暴露头标题
实际请求响应中显示给用户代理(例如浏览器)的标头，以空格分隔.

X-Container-Meta-Access-Control-Expose-Headers
Headers exposed to the user agent (e.g. browser) in the actual request response, space separated.
