腾讯云COSv4 的Python SDK, 目前可以支持Python2.6与Python2.7。
使用pip安装
pip install -U qcloud_cos_v4
手动安装:
python setup.py install
使用python sdk，参照sample.py
# 设置用户属性, 包括appid, secret_id和secret_key
# 这些属性可以在cos控制台获取(https://console.qcloud.com/cos)
appid = 100000 # 替换为用户的appid
secret_id = u'xxxxxxxx' # 替换为用户的secret_id
secret_key = u'xxxxxxx' # 替换为用户的secret_key
region_info = "sh" # # 替换为用户的region，目前可以为 sh/gz/tj/sgp，分别对应于上海，广州，天津,新加坡园区
cos_client = CosClient(appid, secret_id, secret_key, region=region_info)
# 设置要操作的bucket
bucket = u'mybucket'
