QingStor Client Package

Prepare step

install.packages('httr') 
install.packages('xml2') 
install.packages('aws.signature') 
install.packages('data.table') 
install.packages('path\\to\\QingStorRSDK_0.1', repos = NULL, type="source") 

library('Qingstor')

First set as follows in R environment:

Sys.setenv("Qstor_ACCESS_KEY_ID" = "...", "Qstor_SECRET_ACCESS_KEY" = "...", "Qstor_DEFAULT_REGION" = "pek3a")

• get_object

  get an object in memory(now only support csv data, read data as dataframe)

    get_object(object = 'object_name', bucket = 'bucket_name') 

the object_name could be a name under a folder like 'some_folder/object_name'

• put_object

  put an object in Qingstor bucket

R tempPath <- file.path("path","to","folder","xxxx.csv") put_object(file = tempPath , object = basename(tempPath),folder = 'folder_name', bucket = 'bucket_name')

*folder* is optional

• delete_object

  delete an object in Qingstor bucket

R delete_object(object = 'object_name', bucket = 'bucket_name') the object_name could be a name under a folder like 'some_folder/object_name'

• get_bucket

  list the object in Qingstor bucket

  Note : folder is must, even in the root of the bucket . R get_bucket(bucket = 'bucket_name',folder = "/") prefix is support ,example:

R get_bucket(bucket = 'bucket_name',folder = "/",prefix = 'prefix_name')

• Now there is no operation on bucket ,for example create bucket, delete bucket.
