PostObject

Struct PostObject 

Source
pub struct PostObject<'a> { /* private fields */ }
Expand description

此方法用于预签名生成给前端使用,如果需要使用sdk上传使用PutObject方法

注意:上传的签名在有效期内都可以使用,要考虑恶意多次上传等等;所以限制条件要写好

Implementations§

Source§

impl PostObject<'_>

Source

pub async fn generate_policy( self, expiration: OffsetDateTime, ) -> Result<GeneratePolicyResult, Error>

生成用于浏览器表单方式上传所需要的内容

§参数
  • expiration:策略过期时间
§注意

当你使用sts的方式生成policy后。在发起表单请求的时候请求头如果没有携带x-oss-security-token,会报InvalidAccessKeyId的错误

impl<'a> PostObject<'a>

Source

pub fn builder(client: &'a Client) -> PostObjectBuilder<'a>

Create an instance of PostObject using the builder syntax
