Problem description
The position parameter is missing.
Causes
You initiated an AppendObject request, but the position parameter required for this operation is not included in the request URL.
Examples
The required position parameter is missing in the URL of the following request:
POST /example?append HTTP/1.1
Host: versioning-append.oss.aliyuncs.com
Date: Tue, 09 Apr 2019 03:59:33 GMT
Content-Length: 3
Content-Type: application/octet-stream
Authorization: OSS qn6q**************:77Dv****************Solutions
Make that the position parameter is included in the request URL. This parameter specifies the position for the append operation. The value of position in the first AppendObject operation performed on an object must be 0. The value of position in subsequent AppendObject operations performed on the object is the current length of the object. For example, if the value of position specified in the first AppendObject request is 0 and the value of Content-Length is 65536, the value of position in the second AppendObject request must be set to 65536.
An example of the first append request:
POST /example?append&position=0 HTTP/1.1
Host: versioning-append.oss.aliyuncs.com
Date: Tue, 09 Apr 2019 03:59:33 GMT
Content-Length: 3
Content-Type: application/octet-stream
