接続プールサイズの指定

次のサンプルコードは、接続プールサイズを指定する方法の例を示しています。

# -*- coding: utf-8 -*-
import oss2
from oss2.credentials import EnvironmentVariableCredentialsProvider

# We recommend that you do not save access credentials in the project code. Otherwise, access credentials may be leaked. As a result, the security of all resources in your account is compromised. In this example, access credentials are obtained from environment variables. Before you run the sample code, make sure that the environment variables are configured. 
auth = oss2.ProviderAuthV4(EnvironmentVariableCredentialsProvider())

# Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. 
endpoint = "https://oss-cn-hangzhou.aliyuncs.com"
# Specify the ID of the region that maps to the endpoint. Example: cn-hangzhou. This parameter is required if you use the signature algorithm V4.
region = "cn-hangzhou"

# Specify the connection pool size. Default value: 10. 
session = oss2.Session(pool_size=20)

# Specify the name of the bucket. 
bucket = oss2.Bucket(auth, endpoint, 'examplebucket', session=session,region=region)

TLSバージョンの指定

TLSバージョンによって、セキュリティとパフォーマンス機能が異なります。 シナリオに基づいてTLSバージョンを選択します。

次のサンプルコードは、TLSバージョンを1.2に設定する方法の例を示しています。

# -*- coding: utf-8 -*-
import ssl
import oss2
from requests.adapters import HTTPAdapter
from oss2.credentials import EnvironmentVariableCredentialsProvider

# Obtain access credentials from environment variables. Before you run the sample code, make sure that the environment variables are configured. 
auth = oss2.ProviderAuthV4(EnvironmentVariableCredentialsProvider())

# Configure the SSL adapter. 
class SSLAdapter(HTTPAdapter):
    def init_poolmanager(self, *args, **kwargs):
        # Set the TLS version to 1.2. 
        kwargs["ssl_version"] = ssl.PROTOCOL_TLSv1_2
        return super().init_poolmanager(*args, **kwargs)

# Create a session object and configure the adapter by using the session object. 
session = oss2.Session(adapter=SSLAdapter())

# Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. 
endpoint = "https://oss-cn-hangzhou.aliyuncs.com"
# Specify the ID of the region that maps to the endpoint. Example: cn-hangzhou. This parameter is required if you use the signature algorithm V4.
region = "cn-hangzhou"

# Specify the name of the bucket. Example: examplebucket. 
bucket = oss2.Bucket(auth, endpoint, 'examplebucket', session=session, region=region)

# Upload the object. 
bucket.put_object("example.txt", "hello")
