Downloading Subscribed Bills

1. Choose Service List > Storage > Object Storage Service.
2. Click the bucket name.

   

3. In the navigation bar on the left, click Objects. You can view all files of the subscribed bills that have been exported.
   

   • You can search for bills by name prefix. For example, enter 2020-11 in the search box to view all bill files in November 2020.
   • Data generated each day for customers in the monthly settlement mode is estimated. It is suggested that these customers obtain the full bill of a month on the third day of the next month.
   • If the number of rows exceeds a certain threshold, the system automatically splits the bill in CSV format into multiple CSV files.

   After expenditure data storage is enabled, data listed in Table 1 will be automatically exported based on your selection.

Further Description

If you want to download subscribed bills every day, run the following script to set it up. After the setup is completed, the subscribed bills will be automatically downloaded.

The following code example is for reference only. You can make changes to it for development as needed.

#!/usr/bin/python
# -*- coding:utf-8 -*-
import string,os,sys,datetime
import commands
import json

#get date 
date = datetime.date.today()-datetime.timedelta(1)
str_date = date.strftime("%Y%m%d")

AK = ''
SK = ''
server = ''
bucketName = ''
#prefix="Consumedetails_"+str_date
prefix="Resource_Expenditures_"+str_date
print prefix

from com.obs.client.obs_client import ObsClient
# Constructs a obs client instance with your account for accessing OBS
obsClient = ObsClient(access_key_id=AK, secret_access_key=SK, server=server)

#find which billing
resp=obsClient.listObjects(bucketName,prefix)
#billing name
objectKey=resp.body.contents[0].key
localFileDir='/opt/huawei/zcm/data/'+objectKey
# Download the object to a file
print('Downloading an object to dir:' + localFileDir + '\n')
obsClient.getObject(bucketName, objectKey, downloadPath=localFileDir)

Description of parameters:

• AK: access key ID on OBS. One AK maps to only one user but one user can have multiple AKs. The OBS system recognizes the users who access the system by their access key IDs. For information about how to create AK and SK, see Creating Access Keys (AK and SK).
• SK: secret access key on OBS. It is used to access OBS. Authentication information is generated for users based on their SKs and request header fields. An SK matches an AK.
• server: domain name, which is the address of the bucket on the Internet. It can be used for scenarios where the bucket is accessed directly through the domain name, such as cloud application development and data sharing. You can obtain its value from "1" in Figure 1.
• bucketName: name of the bucket used for the subscribed bills. You can obtain its value from "2" in Figure 1.
• prefix: bills that need to be automatically downloaded.
• localFileDir: local directory for storing downloaded bill files.
