Struct GotUploadPolicy

pub struct GotUploadPolicy<'a>(/* private fields */);

获取的上传策略

该数据结构目前和上传策略相同，可以和上传策略相互转换，但之后可能会添加更多字段

Implementations

impl GotUploadPolicy<'_>

pub fn upload_policy(&self) -> &UploadPolicy

获取上传策略

pub fn upload_policy_mut(&mut self) -> &mut UploadPolicy

获取上传策略的可变引用

pub fn into_upload_policy(self) -> UploadPolicy

转换为上传策略

Methods from Deref<Target = UploadPolicy>

pub fn bucket(&self) -> Option<&str>

存储空间约束

pub fn key(&self) -> Option<&str>

对象名称约束或对象名称前缀约束

pub fn use_prefixal_object_key(&self) -> bool

是否是对象名称前缀约束

pub fn is_insert_only(&self) -> bool

是否仅允许新增对象，不允许覆盖对象

pub fn mime_detection_enabled(&self) -> bool

是否启用 MIME 类型自动检测

pub fn token_deadline(&self) -> Option<SystemTime>

上传凭证过期时间

pub fn return_url(&self) -> Option<&str>

Web 端文件上传成功后，浏览器执行 303 跳转的 URL

pub fn return_body(&self) -> Option<&str>

上传成功后，自定义七牛云最终返回给上传端的数据

pub fn callback_urls(&self) -> Option<Split<'_, char>>

上传成功后，七牛云向业务服务器发送 POST 请求的 URL 列表

pub fn callback_host(&self) -> Option<&str>

上传成功后，七牛云向业务服务器发送回调请求时的 Host

pub fn callback_body(&self) -> Option<&str>

上传成功后，七牛云向业务服务器发送回调请求时的内容

支持魔法变量和自定义变量

pub fn callback_body_type(&self) -> Option<&str>

上传成功后，七牛云向业务服务器发送回调请求时的 Content-Type

默认为 application/x-www-form-urlencoded，也可设置为 application/json

pub fn save_key(&self) -> Option<&str>

自定义对象名称

支持魔法变量和自定义变量

pub fn is_save_key_forced(&self) -> bool

是否忽略客户端指定的对象名称，强制使用自定义对象名称进行文件命名

pub fn file_size_limitation(&self) -> (Option<u64>, Option<u64>)

限定上传文件尺寸的范围

返回的第一个元素为最小尺寸，第二个元素为最大尺寸，如果为 None 表示不限制，单位为字节

pub fn mime_types(&self) -> Option<Split<'_, char>>

限定用户上传的文件类型

指定本字段值，七牛服务器会侦测文件内容以判断 MIME 类型，再用判断值跟指定值进行匹配， 匹配成功则允许上传，匹配失败则返回 403 状态码

pub fn file_type(&self) -> Option<FileType>

文件类型

pub fn object_lifetime(&self) -> Option<Duration>

对象生命周期

精确到天

pub fn as_json(&self) -> String

获取 JSON 格式的上传凭证

pub fn get(&self, key: impl JsonValueIndex) -> Option<&JsonValue>

根据指定的上传策略字段获取相应的值

pub fn keys(&self) -> JsonMapKeys<'_>

获取上传策略的字段迭代器

pub fn values(&self) -> JsonMapValues<'_>

获取上传策略的字段值的迭代器
