对象存储 OSS设置CORS规则

详细解答可以参考官方帮助文档

通过Client.SetBucketCORS设置CORS规则：

    import "github.com/aliyun/aliyun-oss-go-sdk/oss"

    client, err := oss.New("Endpoint", "AccessKeyId", "AccessKeySecret")
    if err != nil {
        // HandleError(err)
    }

    rule1 := oss.CORSRule{
        AllowedOrigin: []string{"*"},
        AllowedMethod: []string{"PUT", "GET"},
        AllowedHeader: []string{},
        ExposeHeader:  []string{},
        MaxAgeSeconds: 200,
    }

    rule2 := oss.CORSRule{
        AllowedOrigin: []string{"http://www.a.com", "http://www.b.com"},
        AllowedMethod: []string{"POST"},
        AllowedHeader: []string{"Authorization"},
        ExposeHeader:  []string{"x-oss-test", "x-oss-test1"},
        MaxAgeSeconds: 100,
    }

    err = client.SetBucketCORS("my-bucket", []oss.CORSRule{rule1, rule2})
    if err != nil {
        // HandleError(err)
    }
