First, import the s3 module

import package

from importlib import reload
from s3bz.s3bz import S3

set up dummy data

bucket = 'pybz-test'
key = 'test.dict'
sampleDict = {'test': 'bool'}
USER = None
PW = None

save object

result = S3.save(key = key, 
       objectToSave = sampleDict,
       bucket = bucket,
       user=USER,
       pw = PW,
       accelerate = True)
print(('failed', 'success')[result])

success

check if an object exist

result = S3.exist('', bucket, user=USER, pw=PW, accelerate = True)
print(('doesnt exist', 'exist')[result])

exist

load object

result = S3.load(key = key,
       bucket = bucket,
       user = USER,
       pw = PW,
       accelerate = True)
print(result[0])

{'ib_prcode': '10932', 'ib_brcode': '1003', 'ib_cf_qty': '473', 'new_ib_vs_stock_cv': '391'}

presign download object

url = S3.presign(key=key,
              bucket=bucket,
              expiry = 1000,
              user=USER,
              pw=PW)
print(url)

testing signed link

from s3bz.s3bz import Requests
result = Requests.getContentFromUrl(url)

File operations

save

inputPath = '/tmp/tmpFile.txt'
key = 'tmpFile'
downloadPath = '/tmp/downloadTmpFile.txt'
with open(inputPath , 'w')as f:
  f.write('hello world')

S3.saveFile(key =key ,path = inputPath,bucket = bucket)

load

S3.loadFile(key= key , path = downloadPath, bucket = bucket)

with open(downloadPath, 'r') as f:
  print(f.read())

hello world
