Upload Object

Upload an object

POST /api/archive/:instance/:bucketName/:objectName
POST /api/archive/:instance/:bucketName

_global can be used as instance name to upload to a bucket at the global level.

If the bucketName is user.username then a bucket will be created automatically if it does not exist. Otherwise the bucket must exist before being used.

Simple Upload

In case of simple upload, the objectName has to be specified as part of the URL and the Content-Type header has to be set to the type of the object. The body of the request is the object data.

Form upload

The form based upload can be used to upload an object from an HTML form. In this case the Content-Type of the request is set to multipart/form-data, and the body will contain at least one part which is the object data. This part includes a filename which is used as the object name as well as a Content-Type header. The name attribute for the file part is ignored. Additional parts (which do not specify a filename) will be used as metadata: the name is specified as part of the Content-Disposition and the value is the body of the part.

This can be tested using the curl with the -F option.


POST /api/buckets/_global/my_bucket HTTP/1.1
Host: localhost:8090
User-Agent: curl/7.58.0
Accept: */*
Content-Length: 1090
Content-Type: multipart/form-data; boundary=------------------------7109c709802f7ae4

Content-Disposition: form-data; name="file"; filename="object/name"
Content-Type: text/plain

[object data]
Content-Disposition: form-data; name="name1"

Content-Disposition: form-data; name="name2"


This will create an object named “object/name” with two metadata properties:

   "name1": "value1",
   "name2": "value2"
