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'

# 文件操作 #

# 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 request = UploadFileRequest(bucket, u'/sample_file.txt', u'local_file_1.txt') upload_file_ret = cos_client.upload_file(request) print 'upload file ret:', repr(upload_file_ret)

# 2. 上传文件(覆盖文件) # 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 request = UploadFileRequest(bucket, u'/sample_file.txt', u'local_file_2.txt') request.set_insert_only(0) # 设置允许覆盖 upload_file_ret = cos_client.upload_file(request) print 'overwrite file ret:', repr(upload_file_ret) # 2.2从内存上传文件 request = UploadFileFromBufferRequest(bucket, u'/sample_file.txt', data) request.set_insert_only(0) # 设置允许覆盖 upload_file_ret = cos_client.upload_file_from_buffer(request) print 'overwrite file ret:', repr(upload_file_ret)

# 3. 获取文件属性 request = StatFileRequest(bucket, u'/sample_file.txt') stat_file_ret = cos_client.stat_file(request) print 'stat file ret:', repr(stat_file_ret)

# 4. 更新文件属性 request = UpdateFileRequest(bucket, u'/sample_file.txt')

request.set_biz_attr(u'this is demo file') # 设置文件biz_attr属性,不支持中文 request.set_authority(u'eWRPrivate') # 设置文件的权限 request.set_cache_control(u'cache_xxx') # 设置Cache-Control request.set_content_type(u'application/text') # 设置Content-Type request.set_content_disposition(u'ccccxxx.txt') # 设置Content-Disposition request.set_content_language(u'english') # 设置Content-Language request.set_x_cos_meta(u'x-cos-meta-xxx', u'xxx') # 设置自定义的x-cos-meta-属性 request.set_x_cos_meta(u'x-cos-meta-yyy', u'yyy') # 设置自定义的x-cos-meta-属性

update_file_ret = cos_client.update_file(request) print 'update file ret:', repr(update_file_ret)

# 5. 更新后再次获取文件属性 request = StatFileRequest(bucket, u'/sample_file.txt') stat_file_ret = cos_client.stat_file(request) print 'stat file ret:', repr(stat_file_ret)

# 6. 移动文件, 将sample_file.txt移动位sample_file_move.txt request = MoveFileRequest(bucket, u'/sample_file.txt', u'/sample_file_move.txt') stat_file_ret = cos_client.move_file(request) print 'move file ret:', repr(stat_file_ret)

# 7. 删除文件 request = DelFileRequest(bucket, u'/sample_file_move.txt') del_ret = cos_client.del_file(request) print 'del file ret:', repr(del_ret)

# 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') fp = cos_client.download_object(request) fp.read()

# 目录操作 #

# 1. 生成目录, 目录名为sample_folder request = CreateFolderRequest(bucket, u'/sample_folder/') create_folder_ret = cos_client.create_folder(request) print 'create folder ret:', create_folder_ret

# 2. 更新目录的biz_attr属性 request = UpdateFolderRequest(bucket, u'/sample_folder/', u'this is a test folder') # biz_attr不支持中文 update_folder_ret = cos_client.update_folder(request) print 'update folder ret:', repr(update_folder_ret)

# 3. 获取目录属性 request = StatFolderRequest(bucket, u'/sample_folder/') stat_folder_ret = cos_client.stat_folder(request) print 'stat folder ret:', repr(stat_folder_ret)

# 4. list目录, 获取目录下的成员 request = ListFolderRequest(bucket, u'/sample_folder/') list_folder_ret = cos_client.list_folder(request) print 'list folder ret:', repr(list_folder_ret)

# 5. 删除目录 request = DelFolderRequest(bucket, u'/sample_folder/') delete_folder_ret = cos_client.del_folder(request) print 'delete folder ret:', repr(delete_folder_ret)
