## Quickstart

To easily try out the feature, run the included demo Access Management Plugin program in this directory:

```sh
go run access-manager-plugin.go
```

This program, lets the admin user perform any action and prevents all other users from performing `s3:Put*` operations.

In another terminal start MinIO:

```sh
export MINIO_CI_CD=1
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio123

`http://localhost:8080`, y su JavaScript está tratando de comunicarse con un backend corriendo en `http://localhost` (porque no especificamos un puerto, el navegador asumirá el puerto por defecto `80`).

Entonces, el navegador enviará un request HTTP `OPTIONS` al backend `:80`, y si el backend envía los headers apropiados autorizando la comunicación desde este origen diferente (`http://localhost:8080`), entonces el navegador `:8080` permitirá que el JavaScript en el frontend envíe su request al backend...

   "Id":"PutObjectPolicy",
   "Statement":[{
         "Sid":"DenyObjectsThatAreNotSSEKMS",
         "Effect":"Deny",
         "Principal":"*",
         "Action":"s3:PutObject",
         "Resource":"arn:aws:s3:::multi-key-poc/*",
         "Condition":{
            "Null":{
               "s3:x-amz-server-side-encryption-aws-kms-key-id":"true"
            }
         }
      }
   ]

即使它们都在 `localhost` 中，但是它们使用不同的协议或者端口，所以它们都是不同的「源」。

## 步骤

假设你的浏览器中有一个前端运行在 `http://localhost:8080`，并且它的 JavaScript 正在尝试与运行在 `http://localhost` 的后端通信（因为我们没有指定端口，浏览器会采用默认的端口 `80`）。

然后，浏览器会向后端发送一个 HTTP `OPTIONS` 请求，如果后端发送适当的 headers 来授权来自这个不同源（`http://localhost:8080`）的通信，浏览器将允许前端的 JavaScript 向后端发送请求。

为此，后端必须有一个「允许的源」列表。

在这种情况下，它必须包含 `http://localhost:8080`，前端才能正常工作。

## 通配符

也可以使用 `"*"`（一个「通配符」）声明这个列表，表示全部都是允许的。
