在您开始之前,您需要注册阿里云帐户并获取您的凭证。
from alibabacloud_ocr20191230.client import Client
from alibabacloud_ocr20191230.models import GetAsyncJobResultRequest
from alibabacloud_tea_rpc.models import Config
from alibabacloud_tea_util.models import RuntimeOptions
config = Config(
access_key_id='<access_key_id>',
access_key_secret='<access_key_secret>'
)
# 实例化Client
client = Client(config)
request = GetAsyncJobResultRequest(
job_id='<job_id>'
)
runtime_options = RuntimeOptions()
response = client.get_async_job_result(request, runtime_options)
print(response.to_map())
通过用户信息管理设置 access_key,它们具有该账户完全的权限,请妥善保管。有时出于安全考虑,您不能把具有完全访问权限的主账户 AccessKey 交于一个项目的开发者使用,您可以创建RAM子账户并为子账户授权,使用RAM子用户的 AccessKey 来进行API调用。
from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config
config = Config(
type='access_key', # 凭证类型
access_key_id='accessKeyId', # AccessKeyId
access_key_secret='accessKeySecret', # AccessKeySecret
)
cred = Client(config)
access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
cred_type = cred.get_type()
通过安全令牌服务(Security Token Service,简称 STS),申请临时安全凭证(Temporary Security Credentials,简称 TSC),创建临时安全凭证。
from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config
config = Config(
type='sts', # 凭证类型
access_key_id='accessKeyId', # AccessKeyId
access_key_secret='accessKeySecret', # AccessKeySecret
security_token='securityToken' # STS Token
)
cred = Client(config)
access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
security_token = cred.get_security_token()
cred_type = cred.get_type()
通过指定RAM角色,让凭证自动申请维护 STS Token。你可以通过为 Policy
赋值来限制获取到的 STS Token 的权限。
from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config
config = Config(
type='ram_role_arn', # 凭证类型
access_key_id='accessKeyId', # AccessKeyId
access_key_secret='accessKeySecret', # AccessKeySecret
security_token='securityToken', # STS Token
role_arn='roleArn', # 格式: acs:ram::用户ID:role/角色名
role_session_name='roleSessionName', # 角色会话名称
policy='policy', # 可选, 限制 STS Token 的权限
role_session_expiration=3600 # 可选, 限制 STS Token 的有效时间
)
cred = Client(config)
access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
security_token = cred.get_security_token()
cred_type = cred.get_type()
通过指定角色名称,让凭证自动申请维护 STS Token
from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config
config = Config(
type='ecs_ram_role', # 凭证类型
role_name='roleName' # 账户RoleName,非必填,不填则自动获取,建议设置,可以减少请求
)
cred = Client(config)
access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
security_token = cred.get_security_token()
cred_type = cred.get_type()
通过指定公钥ID和私钥文件,让凭证自动申请维护 AccessKey。仅支持日本站。
from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config
config = Config(
type='rsa_key_pair', # 凭证类型
private_key_file='privateKeyFile', # PrivateKey文件路径
public_key_id='publicKeyId' # 账户PublicKeyId
)
cred = Client(config)
access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
security_token = cred.get_security_token()
cred_type = cred.get_type()
如呼叫中心(CCC)需用此凭证,请自行申请维护 Bearer Token。
from alibabacloud_credentials.client import Client
from alibabacloud_credentials.models import Config
config = Config(
type='bearer', # 凭证类型
bearer_token='bearerToken', # BearerToken
)
cred = Client(config)
access_key_id = cred.get_access_key_id()
access_key_secret = cred.get_access_key_secret()
security_token = cred.get_security_token()
cred_type = cred.get_type()
from alibabacloud_credentials.client import Client as CredClient
from alibabacloud_ocr20191230.client import Client as OcrClient
from alibabacloud_ocr20191230.models import GetAsyncJobResultRequest
from alibabacloud_tea_rpc.models import Config
from alibabacloud_tea_util.models import RuntimeOptions
cred = CredClient()
config = Config(credential=cred)
client = OcrClient(config)
request = GetAsyncJobResultRequest(
job_id='<job_id>'
)
runtime_options = RuntimeOptions()
response = client.get_async_job_result(request, runtime_options)
默认凭证提供程序链查找可用的凭证,寻找顺序如下:
1.环境凭证
在环境变量里寻找环境凭证,如果定义了 ALIBABA_CLOUD_ACCESS_KEY_ID
和 ALIBABA_CLOUD_ACCESS_KEY_SECRET
环境变量且不为空,程序将使用它们创建默认凭证。
2.配置文件
如果用户主目录存在默认文件 ~/.alibabacloud/credentials (Windows 为 C:\Users\USER_NAME\.alibabacloud\credentials)
,程序会自动创建指定类型和名称的凭证。默认文件可以不存在,但解析错误会抛出异常。配置名小写。不同的项目、工具之间可以共用这个配置文件,因为不在项目之内,也不会被意外提交到版本控制。
可以通过定义 ALIBABA_CLOUD_CREDENTIALS_FILE
环境变量修改默认文件的路径。不配置则使用默认配置 default
,也可以设置环境变量 ALIBABA_CLOUD_PROFILE
使用配置。
[default] # 默认配置
enable = true # 启用,没有该选项默认不启用
type = access_key # 认证方式为 access_key
access_key_id = foo # Key
access_key_secret = bar # Secret
[client1] # 命名为 `client1` 的配置
type = ecs_ram_role # 认证方式为 ecs_ram_role
role_name = EcsRamRoleTest # Role Name
[client2] # 命名为 `client2` 的配置
enable = false # 不启用
type = ram_role_arn # 认证方式为 ram_role_arn
region_id = cn-test # 获取session用的region
policy = test # 选填 指定权限
access_key_id = foo
access_key_secret = bar
role_arn = role_arn
role_session_name = session_name # 选填
[client3] # 命名为 `client3` 的配置
type = rsa_key_pair # 认证方式为 rsa_key_pair
public_key_id = publicKeyId # Public Key ID
private_key_file = /your/pk.pem # Private Key 文件
3.实例 RAM 角色
如果定义了环境变量 ALIBABA_CLOUD_ECS_METADATA
且不为空,程序会将该环境变量的值作为角色名称,请求 http://100.100.100.200/latest/meta-data/ram/security-credentials/ 获取临时安全凭证。
