Implementations§

Source§

impl OssRepository

Source

pub fn new(pool: PgPool, config: AppConfig) -> Self

PgPool 构造

Source

pub fn from_db(db: DatabaseConnection, config: AppConfig) -> Self

DatabaseConnection 构造

Source

pub async fn upsert_oss(&self, dto: &OssDto, member_id: i32) -> ApiResult<i32>

新增或更新 OSS 记录,绑定到话数岗位列

Source

pub async fn delete_oss(&self, oss_id: i32) -> ApiResult<Option<String>>

删除 OSS 记录

Source

pub async fn get_upload_credential( &self, episode_id: i32, post_name: &str, filename: &str, ) -> ApiResult<OssCredential>

获取上传凭证

Source

pub async fn get_download_credential( &self, episode_id: i32, post_name: &str, ) -> ApiResult<OssCredential>

获取下载凭证

Source

pub async fn get_image_upload_credential( &self, image_type: &str, filename: &str, ) -> ApiResult<OssCredential>

获取图片上传凭证

Source

pub async fn presigned_image_put_url( &self, object_key: &str, max_bytes: u64, ) -> ApiResult<String>

生成图片桶的预签名 PUT URL(服务端导入图源时上传用)

get_image_upload_credential 不同:此处不校验图片后缀白名单, 且使用更大的大小上限,用于服务端批量上传解压后的页面图片。

Source

pub async fn presigned_image_put_urls( &self, prefix: &str, object_keys: &[String], max_bytes: u64, ) -> ApiResult<Vec<String>>

批量生成图片桶预签名 PUT URL(前端图源解压后逐张直传用)

{prefix}* 前缀策略仅申请一次 STS 联合身份临时凭证, 再用同一份临时密钥对每个对象键分别签名,避免逐张调用 STS 拖慢上传。

§参数
  • prefix: 对象键公共前缀(如 editor/episode_123/),策略按 {prefix}* 授权
  • object_keys: 全部待签名对象键(必须都落在 prefix 下)
  • max_bytes: 单个对象允许的最大字节数
Source

pub fn image_display_url(&self, object_key: &str) -> String

构造图片访问 URL(优先图片 CDN 域名,否则 COS 直链)

Source

pub fn image_bucket_name(&self) -> String

图片桶名

Source

pub async fn get_object_key(&self, oss_id: i32) -> ApiResult<Option<String>>

按 ID 查询 objectKey

Source

pub async fn episode_post_oss_id( &self, episode_id: i32, post_name: &str, ) -> ApiResult<Option<i32>>

查询话数某岗位是否已绑定 OSS 记录(对外只读)

用于「下载图源」判断:provider 未绑定压缩包时改走编辑器页面现打包。
