Request Parameters

This request uses parameters to specify the query range for multipart uploads. Table 1 describes the parameters.

**Table 1** Request parameters
Parameter	Description	Mandatory
delimiter	For a multipart upload that contains delimiters, the string between the first character and the first delimiter in the object name (excluding the prefix specified in the request, if any) are returned as CommonPrefix. Multipart uploads with objects that contain CommonPrefix are considered as a group and returned as one record. The record contains no information about the tasks, only informing the user that the group involves multipart uploads. Type: string	No
prefix	If a prefix is specified, the response only contains tasks whose names start with the prefix value. Type: string	No
max-uploads	Maximum number of multipart upload tasks returned. The value ranges from 1 to 1000. If the value has exceeded this range, 1000 tasks are returned by default. Type: integer	No
key-marker	Lists multipart uploads that follow the value of key-marker. Type: string	No
upload-id-marker	Lists multipart tasks that follow the value of upload-id-marker in key-marker. This parameter only functions together with key-marker. Type: string	No
