logging.basicConfig(level=logging.DEBUG, stream=sys.stdout)

设置用户属性, 包括secret_id, secret_key, region ​

appid已在配置中移除,请在参数 ​

Bucket中带上appid。Bucket由bucketname-appid组成

python
secret_id = 'AKID15IsskiBQACGbAo6WhgcQbVls7HmuG00'     # 替换为用户的secret_id
secret_key = 'csivKvxxrMvSvQpMWHuIz12pThQQlWRW'     # 替换为用户的secret_key
region = 'ap-beijing-1'    # 替换为用户的region
token = ''                 # 使用临时秘钥需要传入Token，默认为空,可不填
config = CosConfig(Region=region, Secret_id=secret_id, Secret_key=secret_key, Token=token)  # 获取配置对象
client = CosS3Client(config)
secret_id = 'AKID15IsskiBQACGbAo6WhgcQbVls7HmuG00'     # 替换为用户的secret_id
secret_key = 'csivKvxxrMvSvQpMWHuIz12pThQQlWRW'     # 替换为用户的secret_key
region = 'ap-beijing-1'    # 替换为用户的region
token = ''                 # 使用临时秘钥需要传入Token，默认为空,可不填
config = CosConfig(Region=region, Secret_id=secret_id, Secret_key=secret_key, Token=token)  # 获取配置对象
client = CosS3Client(config)

文件流 简单上传 ​

python
file_name = 'test.txt'
with open('test.txt', 'rb') as fp:
    response = client.put_object(
        Bucket='test04-123456789',  # Bucket由bucketname-appid组成
        Body=fp,
        Key=file_name,
        StorageClass='STANDARD',
        CacheControl='no-cache',
        ContentDisposition='download.txt'
    )
    print response['ETag']
file_name = 'test.txt'
with open('test.txt', 'rb') as fp:
    response = client.put_object(
        Bucket='test04-123456789',  # Bucket由bucketname-appid组成
        Body=fp,
        Key=file_name,
        StorageClass='STANDARD',
        CacheControl='no-cache',
        ContentDisposition='download.txt'
    )
    print response['ETag']

response = client.put_object(
    Bucket='test04-123456789',
    Body='abcdefg',
    Key=file_name,
    CacheControl='no-cache',
    ContentDisposition='download.txt'

    Body='abcdefg',
    Key=file_name,
    CacheControl='no-cache',
    ContentDisposition='download.txt'
)
print response['ETag']

文件下载 获取文件到本地 ​

python
response = client.get_object(
    Bucket='test04-123456789',
    Key=file_name,
)
response['Body'].get_stream_to_file('output.txt')
response = client.get_object(
    Bucket='test04-123456789',
    Key=file_name,
)
response['Body'].get_stream_to_file('output.txt')

文件下载 获取文件流 ​

python
response = client.get_object(
    Bucket='test04-123456789',
