已经过测试，直接上代码：
# -*- coding: UTF-8 -*-
# 引入模块
from obs import ObsClient
import sys
IS_PYTHON2 = sys.version_info.major == 2 or sys.version < '3'
if IS_PYTHON2:
from urlparse import urlparse
import httplib
else:
import http.client as httplib
from urllib.parse import urlparse
# 创建ObsClient实例
obsClient = ObsClient(
access_key_id='*** Provide your Access Key ***',
secret_access_key='*** Provide your Secret Key ***',
server='https://obs.cn-south-1.myhwclouds.com'
)
bucketName = '*** your bucketname ***''
objectKey = 'test.png'
res = obsClient.createSignedUrl('GET', bucketName, objectKey, expires=3600)
url = res['signedUrl']
print('Getting object using temporary signature url:')
print(res['signedUrl'])
# 关闭obsClient
obsClient.close()
使用自定义域名的情况
当需要使用自定义域名时，配server参数为自定义域名，然后在初始ObsClient的参数中增加参数“is_cname=True” 。
obsClient = ObsClient(
access_key_id='*** Provide your Access Key ***',
secret_access_key='*** Provide your Secret Key ***',
server='***You own domain***',
is_cname=True
)
