# 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'

# 1. 上传文件(默认不覆盖)
#    将本地的local_file_1.txt上传到bucket的根分区下,并命名为sample_file.txt
#    默认不覆盖, 如果cos上文件存在,则会返回错误

# 2.1上传本地文件，将本地的local_file_2.txt上传到bucket的根分区下,覆盖已上传的sample_file.txt

# 3. 获取文件属性
request = StatFileRequest(bucket, u'/sample_file.txt')

# 4. 更新文件属性

# 5. 更新后再次获取文件属性
request = StatFileRequest(bucket, u'/sample_file.txt')

# 6. 移动文件, 将sample_file.txt移动位sample_file_move.txt

# 7. 删除文件
request = DelFileRequest(bucket, u'/sample_file_move.txt')

# 8. 下载文件
request = DownloadFileRequest(bucket, u'/sample_file_move.txt')
del_ret = cos_client.download_file(request)
print 'del file ret:', repr(del_ret)

# 9. 下载文件到内存
request = DownloadObjectRequest(bucket, u'/sample_file_move.txt')
