本文档提供关于存储桶 Referer 白名单或者黑名单的 API 概览以及 SDK 示例代码。

设置存储桶 Referer

功能说明

设置指定存储桶的 Referer 白名单或者黑名单（PUT Bucket referer）。

方法原型

cos_status_t *cos_put_bucket_referer(const cos_request_options_t *options,                                     const cos_string_t *bucket,                                     cos_referer_params_t *referer_params,                                     cos_table_t **resp_headers);
