Multipart Write Example
Following is an example of the entire multipart object uploading POST process, using CURL (with line breaks for ease of reading).
Info
CLUSTER
or <cluster>
in a URL stands for <host>[:<port>]
, where host
is a fully qualified domain name or IP address, plus a port
number if other than 80. If the Host header does not match the domain name, override it with the domain=
argument.
Start the upload with a 0-byte POST. Set the encoding (
&encoding=2:1
) if there is no default encoding or you need a non-default setting:Initiate the upload
curl -i "${cluster}/ ?uploads" -XPOST
In the response, locate the headers for the UploadID and the Content-UUID, which is the new object being created:
Returned headers
Castor-System-UploadID: c88fe8a5daf98f7ce84dc4947238f5c1d0b0b42b8ce464e4566cc2c080ecf401d0b0b42b8ce464e4566cc2c080ecf4010P Content-UUID: c88fe8a5daf98f7ce84dc4947238f5c1
Write the first part using the UploadID and Content-UUID and partNumber=1:
Upload the first part
curl -i "${cluster}/c88fe8a5daf98f7ce84dc4947238f5c1 ?partNumber=1 &uploadid=c88fe8a5daf98f7ce84dc4947238f5c1d0b0b42b8ce464e4566cc2c080ecf401d0b0b42b8ce464e4566cc2c080ecf4010P" -XPOST --data-binary "part 1 data"
